shaft drive hydraulic pump manufacturer

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.

A hydraulic drive motor can be an alternative to an electric motor. However, hydraulic motors may need additional equipment, such as a hydraulic pump and fluid reservoir. They are also bigger and more expensive than electric motors. Hydraulic systems may not fit some applications because they use more energy than electric systems. Manufacturers ought to consult experts or conduct a study when choosing a motor for an application.

A hydraulic motor transforms a revolving shaft and hydraulic energy into mechanical energy. It uses hydraulic pressure and flows to provide the necessary torque and rotation. Hydraulic motors can power winches, crane drives, self-propelled farming machinery, excavators, mixer and agitator drives, and roll mills, to name a few.

A hydraulic motor"s flow, displacement and pressure drop affect how much power and torque it produces. Speed has a direct relationship to the power output. Hydraulic motors come in various speeds, from low-speed hydraulic motors with a minimum speed of 0.5 rpm to high-speed motors with up to 10,000 rpm. Large torques can be generated at low speeds using low-speed hydraulic motors.

Manufacturers should make sure hydraulic motors are geared to the needs of the hydraulic system. One must take into account factors like load, operating pressure, speed, and serviceability. There are various hydraulic motors to choose from, including piston motors, hydraulic vane motors, and internal and external hydraulic gear motors.

The following are the main categories of hydraulic motors:Gear motors can be noisy but affordable and easy to operate. Tehy are well-suited for medium-speed applications.

Hydraulic drive motors are advantageous because of their high power and torque output. They are adaptable to heavy-duty applications due to their ability to tolerate severe environments. Additionally, hydraulic drive motors offer a great degree of precision in robotics and industrial processes. Hydraulic drive motors can manage multiple operations simultaneously. A full hydraulic system may be assembled using hydraulic drive motors and components like pumps and valves.

Compared to other types of motors,hydraulic drive motors are expensive and bulky. Additionally, hydraulic fluid is required to operate hydraulic systems. This fluid can be environmentally hazardous if improperly handled. Hydraulic systems can be intricate and need specific knowledge and upkeep to function. Additionally, because they are frequently made to work at slower rates than electric motors, they might not be appropriate for use in applications requiring high speed.

In a large bulldozer, a hydraulic drive motor might work better than an electric motor. A lot of torque is required to move huge loads, and a hydraulic motor can deliver that more efficiently than an electric motor. Additionally, hydraulic motors can function in settings that could harm electric motors, such as underwater or in extremely hot or cold temperatures.

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 when each form is integrated into an overall power transmission strategy. As a result, it is worthwhile to put in an effort to find honest and skilled hydraulic manufacturers / suppliers who can assist you in developing and implementing an overall hydraulic strategy.

Despite the apparent simplicity of hydraulic systems, engineers and manufacturers must take into account certain variables in order to build an efficient and safe device. The fluid used in the motor or system must be a good lubricant, first and foremost. It should also be chemically stable and compatible with the metals inside the motor. The pump, fluid reservoir and relief valves should be of appropriate power, capacity or strength to allow the motor to perform at optimum levels.

Problems with hydraulic motors can often be traced to poor maintenance, the use of improper fluid within the motor, or improper usage of the motor itself. Some not uncommon causes of motor failure are:

It is important to keep in mind that hydraulic motors are designed to function within certain limits which should not be exceeded. Those limits mainly include torque, pressure, speed, temperature, and load. To give one example, operating a hydraulic motor at excessive temperatures thins hydraulic fluid, negatively affects internal lubrication, and decreases overall the efficiency of the motor. Staying within a motor’s operational limits will preempt unnecessary and needless malfunctions.

In terms of safety, the relative simplicity of hydraulic systems and components (when compared to electrical or mechanical counterparts) does not mean they should not 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.

A container that stores fluid under pressure. Accumulators, the common types of which are piston, bladder and diaphragm, are used as an energy source or to absorb hydraulic shock.

The amount of fluid that passes through a pump, motor or cylinder in a period of time or during a single actuation event, such as a revolution or stroke.

When you begin working with hydraulic pump drives, they can be a bit overwhelming. But, it doesn"t have to be that way. Below we will dive into some pump drive basic info and review the key manufacturers.

A hydraulic pump drive(also referred to as a pump drive) is a device that connects a prime mover to a hydraulic pump. There are several different sizes & configurations available. There are also several different input options, which we will go into more detail about later.

The multi-pad pump drives have a gear train in them to drive the pumps and can be a 1:1 ratio or an increasing or decreasing ratio to drive the hydraulic pumps at the optimal RPM while running the engine at its optimal RPM.

There are various terms used in the field for pump drives. If you hear any of the below nicknames, they are likely referring to a hydraulic pump drive.

Hydraulic pump drives are found in various applications, with the most common being marine, cranes, drilling rigs, construction equipment, and agricultural applications. They can power hoists, boom cylinders, outriggers, drill heads, and power the machine through hydraulic motors.

As machines have gotten more complex in recent years, they now need power for multiple actions during use. Therefore, it is much easier to design a system that drives these loads hydraulically than drive the loads mechanically.

That is where the hydraulic pump drive comes into play in various applications. Additionally, pump drives are pretty simple, comprised of a gearbox with an input, bearings, gears, and outputs to mount with the hydraulic pumps.

The simplest pump drive available is a single pump direct drive, consisting of a flex plate and bell housing plate coupled to one hydraulic pump. Pump drives come in a variety of output sizes, going up to five outputs.

The most common input style is a drive plate input that bolts to the flywheel and housing of the engine. The sizes that are available all abide by the SAE flywheel and SAE housing standards for industrial engines.

There are remote inputs, with the most common being keyed input shafts or flanged input shafts. Lastly, there are clutch inputs, with the most common being a mechanically engaged clutch. Palmer Johnson has the resources to also offer pneumatic or hydraulic engaged clutch inputs for pump drives.

The most common pump drive manufacturers are Funk, Durst, and Twin Disc. All three manufacturers offer a full array of pump drive sizes, ranging from one pad all the way up to a five pad option.

In addition, they all offer an expansive list of input and output options as well as several ratio options that vary depending on the particular pump drive model.
