where is the hydraulic pump located supplier

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.

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.

Technically, hydraulic motors are mechanical actuators; they convert pressure into rotational hydraulic energy and torque. They are also the rotary counterpart of hydraulic cylinders. Because hydraulic motors are driven by engines, they may also be called hydraulic drive motors.

Broadly, hydraulic motors serve the construction, automotive, agriculture, forestry, manufacturing, military, waste management and recycling, aerospace, marine, and oil and energy industries.

They are designed to serve equipment and machinery that need strong pressurized actions to power their functions or parts of their functions. These are functions that could not be supported by the lesser power produced by electric motors.

Hydraulic motors, for example, help raise the wing flaps of airplanes and power the lifting of industrial cranes. Some other of the many machines with which customers use hydraulic motors include agitator and mixer drives, crane drives and self-driven cranes, conveyor and feeder drives, drilling rigs, cars and trucks, drum drives for digesters, high-powered lawn trimmers, the wheel motors of military vehicles, shredders, trench cutters, trommels, kilns, excavators, marine winch drives, and plastic injection machines.

The first hydraulic motors were born during the Industrial Revolution, when industrialist William Armstrong started working on ways to make hydraulic power more efficient. One of the first results of his efforts was his invention of the water powered rotary engine. While his contemporaries did not make much use out his engine, it did serve as an example of a working hydraulic powered rotary actuator upon which later inventors could build. Later, Armstrong designed the hydraulic motor used to the power the Swing Bridge positioned over the River Tyne. His oscillating, single action engine featured three cylinders. Over the years, Armstrong designed many different hydraulic motors, used to power machines like hydraulic cranes and applications related mainly to bridges and docks.

Many of Armstrong’s designed wasted water because they used the same amount of water no matter the load size. This is because they featured fixed strokes and valves with cut-offs operators could not control. To remedy this, engineers such as Arthur Rigg began designing variable stroke hydraulic motors. Generally, operators were able to control water consumption and engine power by adjusting stroke. Arthur Rigg patented his engine design in 1886. It featured a three-cylinder radial engine, the stroke length of which operators could control using a double eccentric mechanism.

Since the Industrial Revolution, engineers have learned ways to use hydraulic power more efficiently and to achieve greater feats. Modern hydraulic systems power hydraulic equipment and products like bulldozers, cranes, kilns, hydraulic lifts, metalworking machines, and much more.

For the best results, manufacturers build the interior hydraulic motor components and main hydraulic motor enclosure from a durable metal, like steel or iron, that can weather both high operating speeds and pressure.

In order to build the best hydraulic motor possible, manufacturers must take a number of factors into consideration, including the state of the relief valves, fluid reservoir, and hydraulic pump. All of these components must all be endowed with levels of strength, capacity, and power that matches the needs of the fluid that will go through them. This fluid, in turn, must be chemically stable and compatible with the metals with which the motor is made, and it must be a good lubricant.

Some of the motor components that manufacturers can customize include torque (starting torque, torque output, breakaway torque, running torque, etc.), motor size, motor range, presence of pistons and shafts, pressure fluid level, and resistance rating.

Hydraulic motors are constructed with a fair amount of simplicity. Its three main parts are the hydraulic pumps, reservoir, and cylinder. Of course, a hydraulic motor, or hydraulic pump motor, would be nothing without the addition of pressurized fluid, usually a type of oil. This hydraulic component creates motion by pushing against it so that the motor’s rotating components spin all the more quickly and generate mechanical energy. Hydraulic motors often also feature input shafts and output shafts. Shafts assist in operation by applying fluid energy to the load.

To work, a small pneumatic engine pumps oil from the reservoir, where it goes from an inlet valve to an outlet valve and through a series of gears and cylinders or turning vanes, depending on the motor’s design.

There are a few different types of hydraulic motors. The main ones, which are each named for the rotating component they use, are vane, gear, and piston hydraulic motors.

Vane motors function using a rotor contained inside a housing with an eccentric bore, that has vanes that slide in and out of it. The sliding motion of the rotor vanes is created by a force differential brought on by an unbalanced force of pressurized fluid. While they are not as efficient as piston motors, vane motors are less expensive than piston motors.

Gear motors, or hydraulic gear motors, consist of a driver gear and an idler gear. To generate power in a gear motor, high pressure fluid is forced into one side of the gears, where it flows around outskirts of the gears to the outlet port, where the gears then interlock and disallow the oil from flowing back out. Here, the gears rotate, generating energy.

Piston motors may use an axial piston pump or a radial piston pump. An axial piston motor pump consists of an odd number of pistons, arranged in a circle around a cylinder block, to regulate fluid pressure and flow. A radial piston motor pump, on the other hand, use pistons mounted around an eccentrically-balanced center shaft, which either radiate inward or outward.

In addition to the basic motor types, there are a few different types of specialized motors, modified for semi-specific applications. These include hydraulic wheel motors, high speed hydraulic motors, high torque hydraulic motors, and gerotor motors.

Hydraulic wheel motors are built directly into wheel hubs, where they contribute the power the wheels require to rotate. Depending on the size of the machine and the power of the motor, a hydraulic wheel motor can control just one or multiple wheels.

High speed hydraulic motors provide higher than normal amounts of power by converting hydraulic pressure fluid into force with an elevated number of rotations per minute.

High torque hydraulic motors, on the other hand, achieve increased torque by running at low speeds, which is why they are often called low speed-high torque (LSHT) motors.

Gerotor motors, or generated rotor motors, are motors that consist of an inner and outer rotor. These hydraulic motors can also work as pistonless rotary engines.

Hydraulic motors offer their users a wide a range of benefits. These benefits include improved power transmission, efficiency, improved power transmission safety, and increased ease and simplicity of power transmission.

In addition, hydraulic motors are much more powerful than electric motors of comparable size. They can also achieve high quality results even in a tight space; manufacturers are able to design compact hydraulic motors that use stroke lengths of less than an inch. A byproduct of this is the fact that they are very versatile.

Examples of hydraulic motor accessories you may require include motor seal kits, pump seal kits, check valves, tubing, pumps, and hydraulic fluid. To find out what accessories are best for your application, talk to your hydraulic motor supplier.

First, check your hydraulic motor regularly for issues like motor input shaft or output shaft misalignment, motor displacement, dirty hydraulic fluid and internal leaks (check motor feed lines and the like).

Second, treat your motor well by never operating it outside of its designed limitations. For example, do not push it beyond its designated load, speed, torque, temperature, and pressure. Exceeding your motor’s designed limits puts it at risks for issues like diminished internal lubrication (associated with excessive heat), single displacement reactions, and general malfunctions.

Finally, for your own safety, always handle your hydraulic motor components with proper care. For example, never make direct physical contact with active hydraulic fluid. Not only could it burn you, but if it is under pressure, it could release with a damaging amount of force. Look to organizations like OSHA to guide you when it comes to handling of hydraulic motors.

As we mentioned in the section above, you should always use hydraulic motors according to the guidelines of OSHA, or the Occupational Safety and Health Administration. OSHA puts out standard guidelines designed to keep you and your workers safe when operating machinery. You should also make sure your manufacturer builds your hydraulic motors in a way that supports OSHA requirements.

In addition to OSHA guidelines, your hydraulic motors likely need to meet the standards of a variety of other organizations. The answer to the question of which organizations and guidelines depends on your industry, application, and location. For example, in the United States, some of the standards organizations most influential in the hydraulics motor industry include the NFPA (National Fluid Power Association), SAE (Society of Automotive Engineers), and ANSI (American National Standards Institute). The premiere organization used internationally is the aptly named ISO, or International Standards Organization. All industries and applications either have their own standards or, most commonly, adapt standards from organizations like these. To find out which standards you should make sure your hydraulic motors meet, talk to your industry leaders.
