Hydraulic systems are in general members of the fluid power branch of power transmission. Hydraulic pumps are also members of the hydraulic power pack/hydraulic power unit family. Hydraulic units are encased mechanical systems that use liquids for hydraulics.
The hydraulic systems that hydraulic pumps support exist in a range of industries, among them agriculture, automotive manufacturing, defense contracting, excavation, and industrial manufacturing. Within these industries, machines and applications that rely on hydraulic pumps include airplane flaps, elevators, cranes, automotive lifts, shock absorbers, automotive brakes, garage jacks, off-highway equipment, log splitters, offshore equipment, hydraulic motors/hydraulic pump motors, and a wide range of other hydraulic equipment.
When designing hydraulic pumps, manufacturers have many options from which to choose in terms of material composition. Most commonly, they make the body of the pump–the gears, pistons, and hydraulic cylinders–from a durable metal material. This metal is one that that can hold up against the erosive and potentially corrosive properties of hydraulic fluids, as well as the wear that comes along with continual pumping. Metals like this include, among others, steel, stainless steel, and aluminum.
First, what are operating specifications of their customer? They must make sure that the pump they design matches customer requirements in terms of capabilities. These capabilities include maximum fluid flow, minimum and maximum operating pressure, horsepower, and operating speeds. Also, based on application specifications, some suppliers may choose to include discharge sensors or another means of monitoring the wellbeing of their hydraulic system.
Next, what is the nature of the space in which the pump will work? Based on the answer to this question, manufacturers will design the pump with a specific weight, rod extension capability, diameter, length, and power source.
Manufacturers must also find out what type of substance does the customer plan on running through the pumps. If the application calls for it, manufacturers can recommend operators add other substances to them in order to decrease the corrosive nature of certain hydraulic fluids. Examples of such fluids include esters, butanol, pump oils, glycols, water, or corrosive inhibitors. These substances differ in operating temperature, flash point, and viscosity, so they must be chosen with care.
All hydraulic pumps are composed in the same basic way. First, they have a reservoir, which is the section of the pump that houses stationary fluid. Next, they use hydraulic hoses or tubes to transfer this fluid into the hydraulic cylinder, which is the main body of the hydraulic system. Inside the cylinder, or cylinders, are two hydraulic valves and one or more pistons or gear systems. One valve is located at each end; they are called the intake check/inlet valve and the discharge check/outlet valve, respectively.
Hydraulic pumps operate under the principle of Pascal’s Law, which states the increase in pressure at one point of an enclosed liquid in equilibrium is equally transferred to all other points of said liquid.
To start, the check valve is closed, making it a normally closed (NC) valve. When the check is closed, fluid pressure builds. The piston forces the valves open and closes repeatedly at variable speeds, increasing pressure in the cylinder until it builds up enough to force the fluid through the discharge valve. In this way, the pump delivers sufficient force and energy to the attached equipment or machinery to move the target load.
When the fluid becomes pressurized enough, the piston withdraws long enough to allow the open check valve to create a vacuum that pulls in hydraulic fluid from the reservoir. From the reservoir, the pressurized fluid moves into the cylinder through the inlet. Inside the cylinder, the fluid picks up more force, which it carries over into the hydraulic system, where it is released through the outlet.
Piston pumps create positive displacement and build pressure using pistons. Piston pumps may be further divided into radial piston pumps and axial piston pumps.
Radial pumps are mostly used to power relatively small flows and very high-pressure applications. They use pistons arranged around a floating center shaft or ring, which can be moved by a control lever, causing eccentricity and the potential for both inward and outward movement.
Axial pumps, on the other hand, only allow linear motion. Despite this, they are very popular, being easier and less expensive to produce, as well as more compact in design.
Gear pumps, or hydraulic gear pumps, create pressure not with pistons but with the interlocking of gear teeth. When teeth are meshed together, fluid has to travel around the outside of the gears, where pressure builds.
External gear pumps facilitate flow by enlisting two identical gears that rotate against each other. As liquid flows in, it is trapped by the teeth and forced around them. It sits, stuck in the cavities between the teeth and the casing, until it is so pressurized by the meshing of the gears that it is forced to the outlet port.
Internal gear pumps, on the other hand, use bi-rotational gears. To begin the pressurizing process, gear pumps first pull in liquid via a suction port between the teeth of the exterior gear, called the rotor, and the teeth of the interior gear, called the idler. From here, liquid travels between the teeth, where they are divided within them. The teeth continue to rotate and mesh, both creating locked pockets of liquid and forming a seal between the suction port and the discharge port. Liquid is discharged and power is transported once the pump head is flooded. Internal gears are quite versatile, usable with a wide variety of fluids, not only including fuel oils and solvents, but also thick liquids like chocolate, asphalt, and adhesives.
Various other types of hydraulic pumps include rotary vane pumps, centrifugal pumps, electric hydraulic pumps, hydraulic clutch pumps, hydraulic plunger pumps, hydraulic water pumps, hydraulic ram pumps, portable 12V hydraulic pumps, hydraulic hand pumps, and air hydraulic pumps.
Rotary vane pumps are fairly high efficiency pumps, though they are not considered high pressure pumps. Vane pumps, which are a type of positive-displacement pump, apply constant but adjustable pressure.
Centrifugal pumps use hydrodynamic energy to move fluids. They feature a rotating axis, an impeller, and a casing or diffuser. Most often, operators use them for applications such as petroleum pumping, sewage, petrochemical pumping, and water turbine functioning.
Electric hydraulic pumps are hydraulic pumps powered by an electric motor. Usually, the hydraulic pump and motor work by turning mechanisms like impellers in order to create pressure differentials, which in turn generate fluid movement. Nearly any type of hydraulic pump can be run with electricity. Most often, operators use them with industrial machinery.
Hydraulic clutch pumps help users engage and disengage vehicle clutch systems. They do so by applying the right pressure for coupling or decoupling shafts in the clutch system. Coupled shafts allow drivers to accelerate, while decoupled shafts allow drivers to decelerate or shift gears.
Hydraulic ram pumps are a type of hydraulic pump designed to harness hydropower, or the power of water, to elevate it. Featuring only two moving hydraulic parts, hydraulic ram pumps require only the momentum of water to work. Operators use hydraulic ram pumps to move water in industries like manufacturing, waste management and sewage, engineering, plumbing, and agriculture. While hydraulic ram pumps return only about 10% of the water they receive, they are widely used in developing countries because they do not require fuel or electricity.
Hydraulic water pumps are any hydraulic pumps used to transfer water. Usually, hydraulic water pumps only require a little bit of energy in the beginning, as the movement and weight of water generate a large amount of usable pressure.
Air hydraulic pumps are hydraulic pumps powered by air compressors. In essence, these energy efficient pumps work by converting air pressure into hydraulic pressure.
Hydraulic pumps are useful for many reasons. First, they are simple. Simple machines are always an advantage because they are less likely to break and easier to repair if they do. Second, because fluid is easy to compress and so quick to create pressure force, hydraulic pumps are very efficient. Next, hydraulic pumps are compact, which means they are easy to fit into small and oddly shaped spaces. This is especially true in comparison to mechanical pumps and electrical pumps, which manufacturers cannot design so compactly. Speaking of design, another asset of hydraulic pumps is their customizability. Manufacturers can modify them easily. Likewise, hydraulic pumps are very versatile, not only because they are customizable, but also because they can work in places where other types of pump systems can’t, such as in the ocean. Furthermore, hydraulic pumps can produce far more power than similarly sized electrical pumps. Finally, these very durable hydraulic components are much less likely to explode than some other types of components.
To make sure that your hydraulic pumps stay useful for a long time, you need to treat them with care. Care includes checking them on a regular basis for problems like insufficient fluid pressure, leaks, and wear and tear. You can use diagnostic technology like discharge sensors to help you with detect failures and measure discharge pressure. Checking vibration signals alone is often not enough.
To keep yourself and your workers safe, you need to always take the proper precautions when operating or performing maintenance and repairs on your hydraulic pumps. For example, you should never make direct contact with hydraulic fluid. For one, the fluid made be corrosive and dangerous to your skin. For two, even if the pump isn’t active at that moment, the fluid can still be pressurized and may potentially harm you if something goes wrong. For more tips on hydraulic pump care and operation, talk to both your supplier and OSHA (Occupational Safety and Health Administration).
Pumps that meet operating standards are the foundation of safe and effective operations, no matter the application. Find out what operating standards your hydraulic pumps should meet by talking to your industry leaders.

Impeller blades revolve inside the casing, rotating the surround fluids. the blades also lubricate and cool the system. Pump bearings are often made to anti-friction, to help the impeller rotate inside the casing. The pump shaft is made of steel, and its size corresponds to the size of the impeller.
A hydraulic hand pump transforms human power into hydraulic energy by combining pressure and flow. The foundation for hydraulic fluid delivery is the simple notion that a handle gives an internal piston leverage under manual pressure. The piston then pushes the hydraulic fluid into the cylinder port. Water and hydraulic fluid are the two most common fluids, and however other pressure media can also be used.
The hydraulic pressure generated can be used to test, calibrate, and adjust various measuring instruments and tools. Hydraulic hand pumps are widely used to load and test mechanical parts when a user requires precise adjustments. They are also used in lifting and lowering heavy things in material handling equipment, which similarly necessitates precise control over the movement of the objects.
The working medium, requisite pressure range, drive type, etc., are only a few of the functional and hydraulic system requirements that are considered when manufacturing hydraulic pumps. In addition, there are numerous design philosophies and hydraulic pump combinations to choose from. Due to this, only a few pumps can completely fulfill all needs. The most common types of hydraulic pumps have already been described.
The use of hydraulic pumps is still common in industrial settings. Elevators, conveyors, mixers, forklifts, pallet jacks, injection molding machines, presses (shear, stamping, bending, etc.), foundries, steel mills, and slitters are examples of equipment used in material handling. With an application"s need, a hydraulic pump is more likely to be used.
Additionally, hydraulic pumps are used in every conceivable mobile or industrial hydraulic machine. They are used on many different pieces of gear, such as excavators, cranes, loaders, tractors, vacuum trucks, forestry equipment, graders, dump trucks, and mining equipment. Mobile applications use hydraulic pumps more commonly than industrial applications since industrial devices typically don"t use electric actuators.

Hydraulic pumps (sometimes erroneously referred to as "hydrolic" pumps) are devices within hydraulic systems that transport hydraulic liquids from one point to another to initiate the creation of hydraulic power. They are an important component overall in the field of hydraulics, a specialized form of power transmission that harnesses the energy transmitted by moving liquids under pressure and converts it into mechanical energy. Other types of pumps that are used to transmit hydraulic fluids may also be called hydraulic pumps. Because of the wide variety of contexts in which hydraulic systems are employed, hydraulic pumps are very important in various industrial, commercial and consumer utilities.
The term power transmission refers to the overall process of technologically converting energy into a useful form for practical applications. Three main branches compose the field of power transmission: electrical power, mechanical power, and fluid power. Fluid power encompasses the use of moving gases and well as moving liquids for power transmission. Hydraulics, then, can be considered as a sub-branch of fluid power which focuses on liquid usage as opposed to gas usage. The other field of fluid power is known as pneumatics and revolves around storing and releasing energy with compressed gas.
As described above, the incompressible nature of fluid within hydraulic systems enables an operator to create and apply mechanical power in a very efficient manner. Practically all of the force generated within a hydraulic system is applied to its intended target.
Because of the relationship between force, area, and pressure (F = P x A), it is relatively easy to modify the force of a hydraulic system simply by modifying the size of its components.
Hydraulic systems can transmit power on par with many electrical and mechanical systems while being generally simpler at the same time. For example, it is easy to directly create linear motion with a hydraulic system. On the contrary, electrical and mechanical power systems generally require an intermediate mechanical step to produce linear motion from rotational motion.
Hydraulic power systems are generally smaller than their electrical and mechanical counterparts while generating similar amounts of power, thus providing the advantage of conserving physical space.
The basic design of hydraulic systems (a reservoir/pump connected to actuators by some sort of piping system) allows them to be used in a wide variety of physical settings. Hydraulic systems can also be used in environments that are impractical for electrical systems (e.g. underwater).
Using hydraulic systems in place of electrical power transmission increases relative safety by eliminating electrical safety hazards (e.g. explosions, electric shock).
A major, specific advantage of hydraulic pumps is the amount of power they are able to generate. In some cases, a hydraulic pump can produce ten times the amount of power produced by an electrical counterpart. Some types of hydraulic pumps (e.g. piston pumps) are more expensive than the average hydraulic component. These types of disadvantages, however, may be offset by the pump’s power and efficiency. For example, piston pumps are prized for their durability and ability to transmit very viscous fluids, despite their relatively high cost.
The essence of hydraulics lies in a fundamental physical reality: liquids are incompressible. Because of this, liquids resemble solids more than compressible gases. The incompressible nature of liquid enables it to transmit force very efficiently in terms of force and speed. This fact is summarized by a version of "Pascal’s Law" or "Pascal’s Principle", which states that virtually all of the pressure applied to any part of a (confined) fluid will be transmitted to every other part of the fluid. Using alternative terms, this scientific principle states that pressure exerted on a (confined) fluid transmits equally in every direction.
Furthermore, force transmitted within a fluid has the potential to multiply during its transmission. From a slightly more abstract point of view, the incompressible nature of liquids means that pressurized liquids must maintain a constant pressure even as they move. Pressure, from a mathematical point of view, is force acting per a specific area unit (P = F/A). A rearranged version of this equation makes it clear that force equals the product of pressure times area (F = P x A). Thus, by modifying the size or area of certain components within a hydraulic system, the force acting within a hydraulic system can also be modified accordingly (to either greater or lesser). The need for pressure to stay constant is responsible for making force and area reflect each other (in terms of either growing or shrinking). This force-area relationship can be illustrated by a hydraulic system containing a piston that is five times bigger than a second piston. if a certain force (e.g. 50 pounds) is applied to the smaller piston, that force will be multiplied by five (e.g. to 250 pounds) as it is transmitted to the larger piston within the hydraulic system.
The chemical nature of liquids as well as the physical relationship between force, area, and pressure form the foundation of hydraulics. Overall, hydraulic applications enable human operators to create and apply massive mechanical forces without exerting much physical effort at all. Water and oil are both used for power transmission within hydraulic systems. The use of oil, however, is far more common, due in part to its very incompressible nature.
It has previously been noted that "Pascal’s Law" applies to confined liquids. Thus, for liquids to act in a hydraulic fashion, it must function with some type of enclosed system. An enclosed mechanical system that uses liquid hydraulically is known as a hydraulic power pack or a hydraulic power unit. Though specific operating systems are variable, all hydraulic power packs (or units) have the same basic components. These components generally include a reservoir, a pump, a piping/tubing system, valves, and actuators (including both cylinders and motors). Similarly, despite the versatility and adaptability of these mechanisms, these components all work together within similar operating processes, which lie behind all hydraulic power packs.
Hoses or tubes are needed to transport the viscous liquids transmitted from the pump. This piping apparatus then transports the solution to the hydraulic cylinder.
Actuators are hydraulic components which perform the main conversion of hydraulic energy into mechanical energy. Actuators are mainly represented by hydraulic cylinders and hydraulic motors. The main difference between hydraulic cylinders and hydraulic motors lies in the fact that hydraulic cylinders primarily produce linear mechanical motion while hydraulic motors primarily produce rotary mechanical motion.
Hydraulic systems possess various valves to regulate the flow of liquid within a hydraulic system. Directional control valves are used to modify the size and direction of hydraulic fluid flow, while pressure relief valves preempt excessive pressure by limiting the output of the actuators and redirecting fluid back to the reservoir if necessary.
Two main categories of hydraulic pumps to be considered are piston pumps and gear pumps. Within the piston grouping are axial and radial piston pumps. Axial pumps provide linear motion, while radial pumps can operate in a rotary manner. The gear pump category is also divided into two groupings, internal gear pumps and external gear pumps.
No matter piston or gear, each type of hydraulic pump can be either a single-action or double-action pump. Single-action pumps can push, pull or lift in only one direction, while double-action pumps are multidirectional.
The transfer of energy from hydraulic to mechanical is the end goal, with the pump mechanism serving as a generator. In other cases, however, the energy is expelled by means of high pressure streams that help to push, pull and lift heavy loads.
Hydraulic piston pumps and hydraulic clutch pumps, which operate in slightly different ways, are all utilized in heavy machinery for their versatility of motion and directionality.
And hydraulic water pumps are widely used to transfer water. The design of these pumps dictates that, although a small amount of external energy is needed to initiate the action, the weight of the water and its movement can create enough pressure to operate the pump continuously thereafter. Hydraulic ram pumps require virtually no maintenance, as they have only two moving parts. Water from an elevated water source enters one of two chambers through a relatively long, thick pipe, developing inertia as it moves down to the second chamber, which starts the pump.
The initial energy within a hydraulic system is produced in many ways. The simplest form is the hydraulic hand pump which requires a person to manually pressurize the hydraulic fluid. Hydraulic hand pumps are manually operated to pressurize a hydraulic system. Hydraulic hand pumps are often used to calibrate instruments.
Energy-saving pumps that are operated by a compressed air source and require no energy to maintain system pressure. In both the single and two-stage air hydraulic pumps, air pressure is simply converted to hydraulic pressure, and they stall when enough pressure is developed.
Non-positive displacement pumps that are used in hydraulics requiring a large volume of flow. Centrifugal pumps operate at fairly low pressures and are either diffuser or volute types.
Convert hydraulic energy to mechanical power. Hydraulic pumps are specially designed mechanisms used in industrial, commercial and residential settings to create useful energy from the pressurization of various viscous fluids. Hydraulic pumps are extremely simple yet effective mechanisms for moving liquids. "Hydralic" is actually a misspelling of "hydraulic;" hydraulic pumps rely on the power provided by hydraulic cylinders to power various machines and mechanisms.
Pumps in which the clamps and cylinders are quickly extended by high flow at low pressure in the first stage of operation. In the second stage, piston pumps build pressure to a preset level and then maintain that level.
The construction, automotive manufacturing, excavation, agriculture, defense contracting and manufacturing industries are just a few examples of operations that utilize the power of hydraulics in normal, daily processes. Since the use of hydraulics is so widespread, hydraulic pumps are naturally used in a broad array of industries and machines. In all of the contexts which use hydraulic machinery, pumps perform the same basic role of transmitting hydraulic fluid from one place to another to create hydraulic pressure and energy (in conjunction with the actuators).
Various products that use hydraulics include elevators, automotive lifts, automotive brakes, airplane flaps, cranes, shock absorbers, motorboat steering systems, garage jacks, log splitters, etc. Construction sites represent the most common application of hydraulics in large hydraulic machines and various forms of "off-highway" equipment such as diggers, dumpers, excavators, etc. In other environments such as factories and offshore work areas, hydraulic systems are used to power heavy machinery, move heavy equipment, cut and bend material, etc.
While hydraulic power transmission is extremely useful in a wide variety of professional applications, it is generally unwise to depend exclusively on one form of power transmission. On the contrary, combining different forms of power transmission (hydraulic, pneumatic, electrical and mechanical) is the most efficient strategy. Thus, hydraulic systems should be carefully integrated into an overall strategy of power transmission for your specific commercial application. You should invest in finding honest and skilled hydraulic manufacturers / suppliers who can assist you in developing and implementing an overall hydraulic strategy.
When selecting a hydraulic pump, its intended use should be considered when selecting a particular type. This is important since some pumps may carry out only one task, while others allow more flexibility.
The material composition of the pump should also be considered in an application-specific context. The pistons, gears and cylinders are often made of durable materials such as aluminum, steel or stainless steel which can endure the constant wear of repetitive pumping. The materials must hold up not only to the process itself, but to the hydraulic fluids as well. Oils, esters, butanol, polyalkylene glycols and corrosion inhibitors are often included in composite fluids (though simply water is also used in some instances). These fluids vary in terms of viscosity, operating temperature and flash point.
Along with material considerations, manufacturers should compare operating specifications of hydraulic pumps to ensure that intended use does not exceed pump capabilities. Continuous operating pressure, maximum operating pressure, operating speed, horsepower, power source, maximum fluid flow and pump weight are just a few of the many variables in hydraulic pump functionality. Standard measurements such as diameter, length and rod extension should also be compared. As hydraulic pumps are used in motors, cranes, lifts and other heavy machinery, it is integral that they meet operating standards.
It is important to remember that the overall power produced by any hydraulic drive system is affected by various inefficiencies that must be taken into account to get the maximum use out of the system. For example, the presence of air bubbles within a hydraulic drive is notorious for diverting the energy flow within the system (since energy gets wasted en route to the actuators on compressing the bubbles). Using a hydraulic drive system must involve identifying these types of inefficiencies and selecting the best components to mitigate their effects. A hydraulic pump can be considered as the "generator" side of a hydraulic system which begins the hydraulic process (as opposed to the "actuator" side which completes the hydraulic process). Despite their differences, all hydraulic pumps are somehow responsible for displacing fluid volume and bringing it from the reservoir to the actuator(s) via the tubing system. Pumps are generally enabled to do this by some type of internal combustion system.
Even though hydraulic systems are simpler when compared to electrical or mechanical systems, they are still sophisticated systems that should only be handled with care. A fundamental safety precaution when interacting with hydraulic systems is to avoid physical contact if possible. Active fluid pressure within a hydraulic system can pose a hazard even if a hydraulic machine is not actively operating.
Insufficient pumps can lead to mechanical failure in the workplace, which can have serious and costly repercussions. Although pump failure has been unpredictable in the past, new diagnostic technologies continue to improve on detection methods that previously relied upon vibration signals alone. Measuring discharge pressures allows manufacturers to more accurately predict pump wear. Discharge sensors can be easily integrated into existing systems, adding to the safety and versatility of the hydraulic pump.
A container that stores fluid under pressure and is utilized as a source of energy or to absorb hydraulic shock. Accumulator types include piston, bladder and diaphragm.
A circumstance that occurs in pumps when existing space is not filled by available fluid. Cavitation will deteriorate the hydraulic oil and cause erosion of the inlet metal.
Any device used to convert potential energy into kinetic energy within a hydraulic system. Motors and manual energy are both sources of power in hydraulic power units.
A slippery and viscous liquid that is not miscible with water. Oil is often used in conjunction with hydraulic systems because it cannot be compressed.
A device used for converting hydraulic power to mechanical energy. In hydraulic pumps, the piston is responsible for pushing down and pulling up the ram.
A hydraulic mechanism that uses the kinetic energy of a flowing liquid to force a small amount of the liquid to a reservoir contained at a higher level.
A device used to regulate the amount of hydraulic or air flow. In the closed position, there is zero flow, but when the valve is fully open, flow is unrestricted.
Hydraulic motors (sometimes incorrectly spelled as “hydrolic” motors) convert hydraulic pressure into force that is able to generate great power. They are a type of actuator that converts the pressure of the moving hydraulic fluid into torque and rotational energy.
Hydraulic motors are an important component overall in the field of hydraulics, a specialized form of power transmission that harnesses the energy transmitted by moving liquids under pressure and converts it into mechanical energy. Power transmission is a general term denoting the field of translating energy into usable, everyday forms. The three main branches of power transmission are electrical power, mechanical power, and fluid power. Fluid power can further be divided into the field of hydraulics and the field of pneumatics (translating the energy in compressed gas into mechanical energy).
Arguably, hydraulic power traces back to the beginnings of human civilization. For thousands of years, humans have harnessed the power of moving water for energy. (The most basic “hydraulic” application is harnessing moving water to turn wheels.) For a brief survey of hydraulic history, please refer to our article on Hydraulic Cylinders.
In terms of hydraulic motor development, the middle of the Industrial Revolution proved to be a notable turning point. During that year, English industrialist William Armstrong started developing more efficient applications of hydraulic power after observing inefficiencies in water wheel usage on a fishing trip. One of his first inventions was a rotary, water-powered engine. Unfortunately, this invention failed to attract much attention, but it provided an early model for a rotary actuator based on hydraulic power.
The use of hydraulic systems in general offer several advantages within the overall field of power transmission. Some of those advantages include efficiency, simplicity, versatility, relative safety, etc. These and other advantages are further elaborated on in our article on Hydraulic Pumps.
Hydraulic motors are able to produce much more power than other motors of the same size and for this reason are used for larger loads than electric motors.
When space constrictions are an issue, small hydraulic motors are used. Small hydraulic motors have small stroke lengths; they may be less than an inch.
A major disadvantage of using hydraulic motors is inefficient usage of the actual energy source. Power systems with hydraulic motors can consume large amounts of hydraulic fluid. For example, it is not uncommon for hydraulically-driven machines on construction sites to require 100 or more gallons of hydraulic oil to operate.
Since they are often confused in everyday language, it is important to distinguish between hydraulic motors and hydraulic power packs or hydraulic power units. Technically speaking, an enclosed mechanical system that uses liquid to produce hydraulic power is known as a hydraulic power pack or a hydraulic power unit. These packs, or units, generally include a reservoir, a pump, a piping/tubing system, valves, and actuators (including both cylinders and motors). It is not uncommon, however, to hear a hydraulic motor described as consisting of these components – a reservoir, a pump, etc. However, it is more accurate to describe a hydraulic motor as a part of an overall hydraulic power system that works in sync with these other components. Hydraulic motors are a type of actuating component within an overall hydraulic power system – a component responsible for actually translating hydraulic energy into mechanical energy.
Liquids represent a “median” state between gases and solids on the matter spectrum. Despite this, liquids represent solids far more than gases in an important aspect: they are virtually incompressible. One consequence of this is that force applied to one point in a confined liquid can be transmitted quite efficiently to another point in that same liquid. This reality forms the basis of the mechanical energy that hydraulic systems are able to produce. For a fuller explanation of how hydraulic power works, please refer to our article on Hydraulic Pumps.
It has previously been noted that “Pascal’s Law” applies to confined liquids. Thus, for liquids to act in a hydraulic fashion, it must function with some type of enclosed system. As noticed in the introduction, these “systems” are known as hydraulic power packs and share three main parts—a reservoir, a pump and an actuator—that work together to convert hydraulic energy into mechanical energy.
Hydraulic motors are an integral part of machines that rely on hydraulic power for operation because they actuate and “complete” the process of converting hydraulic energy into mechanical energy. Since hydraulic motors are fairly simple machines that are composed of rotating machinery, they specifically translate hydraulic energy into rotational mechanical energy. The main enclosure and interior components of the motor are made from metal such as steel or iron so they can withstand high pressures and operating speeds. In a sense, motors can be thought of as hydraulic pumps working “backward” or in reverse.
Overall, a hydraulic power unit pumps fluid (usually a type of oil) via a small pneumatic engine from a reservoir and sends it to the motor while regulating fluid temperature. Oil is pumped from the reservoir through an inlet valve to an outlet valve through a series of gears, turning vanes or cylinders, depending on what specific type of hydraulic motor it is. Pressurized fluid creates mechanical energy and motion by physically pushing the motor, causing the rotating components to turn very quickly, and transferring energy to the machinery that the motor is linked to. Typically, not every rotational component is directly connected to producing mechanical energy; for example, in a typical gear motor, only one of the two gears is connected to and responsible for turning the motor shaft. This type of operation directly contrasts with electric engines, in which electromagnetic forces produced by flowing electric current are the response for rotating the motor shaft.
Hydraulic motors, rotary or mechanical actuators which is operated by the conversion of hydraulic pressure or fluid energy to torque and angular displacement.
Driveshaft, a part of the hydraulic motor that delivers or transfers the torque created inside the motor to the outside environment where it is used for lifting loads and other applications.
Vane hydraulic motors have a hydraulic balance that prevents the rotor from sideloading the shaft, with the pressure difference develops the torque as the oil from the pump is forced through the motor.
There are three basic kinds of hydraulics motors: gear, vane and piston type. Each is identified by the design of the rotating component inside. Collectively, the various types of hydraulic motors are optimal for a wide range of specific applications, conditions or usages.
Another common type of hydraulic motor. Radial piston hydraulic motors have pistons mounted around a center shaft that is eccentrically balanced. Fluid causes the pistons to move outward, causing rotation. Axial piston hydraulic motors derive their name from the fact they use axial instead of radial motion, despite their similar design to radial piston motors.
Built into wheel hubs to supply the power needed to rotate the wheels and move the vehicle. A hydraulic wheel motor can operate a single wheel or multiple wheels, depending on the power of the motor and the size of the machine.
Other motors focus on the rotational speed and torque. High speed hydraulic motors convert hydraulic pressure into force at elevated rotations per minute thereby generating large amounts of power. High torque hydraulic motors run at low speeds while operating with increased torque, thus earning the name low speed-high torque (LSHT) motors.
Advances are still being made to hydraulic motors and their various applications. One example is the development of hybrid hydraulic automobiles, which are being developed as an alternative to gas/electric hybrid cars. Hybrid hydraulic vehicles are particularly efficient at reclaiming energy when braking or slowing down.
A type of orbital hydraulic motor, have rollers that are hydro-dynamically supported to minimize friction, ensuring maximum durability and high output at high pressure.
A type of orbital hydraulic motor, are particularly suited for long working cycles at average pressure. Rotor motors are operated by lobes that are fixed and set directly on the stator.
Hydraulic systems and their use are abundant in a wide variety of fields including construction fields, agricultural fields, industrial fields, transportation fields (e.g. automotive, aerospace), various marine work environments, etc. Hydraulic motors are commonly used in machinery that requires strong pressurized actions such as aircraft for raising the wing flaps, heavy duty construction vehicles such as backhoes or crane industrial lifting or for powering automated manufacturing systems. Hydraulics motors are also used in trenchers, automobiles, construction equipment, drives for marine winches, waste management and recycling processes, wheel motors for military vehicles, self-driven cranes, excavators, forestry, agriculture, conveyor and auger systems, dredging and industrial processing.
While hydraulic power transmission is extremely useful in a wide variety of professional applications, it is generally not recommended to use only one form of power transmission. Although it is somewhat counter-intuitive, the maximum benefit of each form of power transmission (electrical, mechanical, pneumatic, and hydraulic) occurs
