Hydraulic motor is an executive element of hydraulic system, which transforms the liquid pressure energy provided by hydraulic pump into mechanical energy (torque and speed) of its output shaft. Hydraulic motors are mainly used in injection molding machinery, ships, cranes, engineering machinery, construction machinery, coal mining machinery, mining machinery, metallurgical machinery, marine machinery, petrochemical industry, port machinery, etc.

Hydraulic motor according to its structure type can be divided into gear type, vane type, plunger type and other types. According to the rated speed of the hydraulic motor is divided into two categories: high speed and low speed. Rated speed higher than 500r/min belongs to the high speed hydraulic motor, rated speed lower than 500r/min belongs to the low speed hydraulic motor. The basic type of high-speed hydraulic motors are gear type, screw type, vane type and axial plunger type. Their main characteristics are high speed, small rotational inertia, easy to start and brake, adjustment (speed regulation and directional) sensitivity is high. Usually high speed hydraulic motor output torque is not large, so also known as high speed small torque hydraulic motor. The basic type of low-speed hydraulic motor is radial piston type, in addition to the axial piston type, vane type and gear type also has a low-speed structure type, low-speed hydraulic motor is the main characteristic of displacement, large volume of low speed (sometimes up to a few revolutions per minute or even a few revolutions), so can be directly connected with the work mechanism, do not need a reduction device, so that the transmission mechanism is greatly simplified, usually low-speed hydraulic motor output torque is larger. Therefore, it is also called low-speed large.

Hydraulic motors are mechanical actuators that convert hydraulic pressure and flow into torque and angular displacement (rotation). Hydraulic motors are the rotary counterparts of hydraulic cylinders as linear actuators. ATO has high torque, high speed, high efficiency hydraulic radial piston motor, hydraulic pump motor, hydraulic orbital motor, optional working power 8-50 horsepower (6 kW-38 kW), rated pressure 2300~3600 psi, speed range 15-1500 rpm , ATO hydraulic motors have competitive prices and a wide range of applications.

Using mechanical energy produced by a machine’s engine, a hydraulic pump can move hydraulic fluid from the pump’s own reservoir to a connected hydraulic motor, converting the mechanical energy to hydraulic energy. The incoming fluid/energy triggers the hydraulic motor to begin rotation, which can be used to actuate a component outside the system, such as a wheel or axle. The power of hydraulics allows for machines to do more with less, such as traversing tough terrain or lifting heavy loads.

In the world of hydraulics, the performance range of gear pumps and piston pumps overlap for low-speed, high-torque applications. So why would an engineer select one over the other? What kinds of advantages and disadvantages do piston pumps have compared to gear pumps?

Piston pumps provide robust performance for myriad applications. Compared to a gear pump, a piston pump can operate at higher pressures with the same flow performance. Typically, gear pumps are rated for around 3,000 psi, but some models reach as high as 5,000 psi. On the other hand, piston pumps can be rated to as high as 30,000 psi.

Piston pumps have the ability to produce variable displacement. Variable displacement is the act of adjusting flow during the usage of the pump while maintaining the same motor speed. Conversely, pumps that use fixed displacement can only operate at one flow specification. By using internal controllers, like springs and dampeners, a piston pump can change displacement while maintaining the same motor speed. Gear pumps require external valving to attain this effect, which can increase the cost of the overall unit.

While a piston pump provides greater pressure ratings and flow controls, a gear pump is a more cost-effective option. The gear pump’s interlocking gear design is simpler and easier to produce on a large scale, allowing for consumers to purchase the product at a lower cost. If an application requires a lower pressure rating and is able to operate using fixed displacement, a gear pump may be the proper solution.

The engineers at Parker Pump and Motor Division have developed the HP Series of pumps, ideal for the low-speed, high torque (LSHT) applications. The HP Series is the only line of the closed loop, variable displacement pumps, designed specifically for LSHT applications, with an integrated oil reservoir, filter, and cooling fan. This compact model saves an engineer space within a design and reduces the number of components from 72 to 5. HP pumps are designed for superior performance and longer life; up to 20% more efficient than other pump and motor systems. They are compact and able to fit in small machine platforms where space is limited. They also easily connect to various Parker Torqmotors, providing ultimate design flexibility.

“The HP series was designed to complement our transmission technology by addressing specific customer needs. Those requirements included durability, compactness, integrated features to lessen leak points and reduced OEM assembly time. HP1 single pumps incorporate a proven design with integrated filter, reservoir and a low center of gravity pulley attachment point. HP2 dual pumps can be direct mounted to a horizontal shaft engine, so there is no need for belts and pulleys. Like the HP1, the HP2 has an integrated filter, reservoir and fan for cooling. Both units, paired with our LSHT motors, provide design versatility to better serve our customers,” said Somer Malone, senior engineer, Parker Hannifin.

In a condition-based maintenance environment, the decision to change out a hydraulic pump or motor is usually based on remaining bearing life or deteriorating efficiency, whichever occurs first.

Despite recent advances in predictive maintenance technologies, the maintenance professional’s ability to determine the remaining bearing life of a pump or motor, with a high degree of accuracy, remains elusive.

Deteriorating efficiency on the other hand is easy to detect, because it typically shows itself through increased cycle times. In other words, the machine slows down. When this occurs, quantification of the efficiency loss isn’t always necessary. If the machine slows to the point where its cycle time is unacceptably slow, the pump or motor is replaced. End of story.

In certain situations, however, it can be helpful, even necessary, to quantify the pump or motor’s actual efficiency and compare it to the component’s native efficiency. For this, an understanding of hydraulic pump and motor efficiency ratings is essential.

There are three categories of efficiency used to describe hydraulic pumps (and motors): volumetric efficiency, mechanical/hydraulic efficiency and overall efficiency.

Volumetric efficiency is determined by dividing the actual flow delivered by a pump at a given pressure by its theoretical flow. Theoreticalflow is calculated by multiplying the pump’s displacement per revolution by its driven speed. So if the pump has a displacement of 100 cc/rev and is being driven at 1000 RPM, its theoretical flow is 100 liters/minute.

Actualflow has to be measured using a flow meter. If when tested, the above pump had an actual flow of 90 liters/minute at 207 bar (3000 PSI), we can say the pump has a volumetric efficiency of 90% at 207 bar (90 / 100 x 100 = 90%).

Its volumetric efficiency used most in the field to determine the condition of a hydraulic pump - based on its increase in internal leakage through wear or damage. But without reference to theoretical flow, the actual flow measured by the flow meter would be meaningless.

A pump’s mechanical/hydraulic efficiency is determined by dividing thetheoretical torque required to drive it by the actual torque required to drive it. A mechanical/hydraulic efficiency of 100 percent would mean if the pump was delivering flow at zero pressure, no force or torque would be required to drive it. Intuitively, we know this is not possible, due to mechanical and fluid friction.

Table 1. The typical overall efficiencies of hydraulic pumps, as shown above, are simply the product of volumetric and mechanical/hydraulic efficiency.Source: Bosch Rexroth

Like theoretical flow, theoretical drive torque can be calculated. For the above pump, in SI units: 100 cc/rev x 207 bar / 20 x p = 329 Newton meters. But like actual flow, actual drive torque must be measured and this requires the use of a dynamometer. Not something we can - or need - to do in the field. For the purposes of this example though, assume the actual drive torque was 360 Nm. Mechanical efficiency would be 91% (329 / 360 x 100 = 91%).

Overall efficiency is simply the product of volumetric and mechanical/hydraulic efficiency. Continuing with the above example, the overall efficiency of the pump is 0.9 x 0.91 x 100 = 82%. Typical overall efficiencies for different types of hydraulic pumps are shown in the Table 1.

System designers use the pump manufacturers’ volumetric efficiency value to calculate the actual flow a pump of a given displacement, operating at a particular pressure, will deliver.

As already mentioned, volumetric efficiency is used in the field to assess the condition of a pump, based on the increase in internal leakage due to wear or damage.

When calculating volumetric efficiency based on actual flow testing, it’s important to be aware that the various leakage paths within the pump are usually constant. This means if pump flow is tested at less than full displacement (or maximum RPM) this will skew the calculated efficiency - unless leakage is treated as a constant and a necessary adjustment made.

For example, consider a variable displacement pump with a maximum flow rate of 100 liters/minute. If it was flow tested at full displacement and the measured flow rate was 90 liters/minute, the calculated volumetric efficiency would be 90 percent (90/100 x 100). But if the same pump was flow tested at the same pressure and oil temperature but at half displacement (50 L/min), the leakage losses would still be 10 liters/minute, and so the calculated volumetric efficiency would be 80 percent (40/50 x 100).

The second calculation is not actually wrong, but it requires qualification: this pump is 80 percent efficient at half displacement. Because the leakage losses of 10 liters/minute are nearly constant, the same pump tested under the same conditions will be 90 percent efficient at 100 percent displacement (100 L/min) - and 0 percent efficient at 10 percent displacement (10 L/min).

To help understand why pump leakage at a given pressure and temperature is virtually constant, think of the various leakage paths as fixed orifices. The rate of flow through an orifice is dependant on the diameter (and shape) of the orifice, the pressure drop across it and fluid viscosity. This means that if these variables remain constant, the rate of internal leakage remains constant, independent of the pump"s displacement or shaft speed.

Overall efficiency is used to calculate the drive power required by a pump at a given flow and pressure. For example, using the overall efficiencies from the table above, let us calculate the required drive power for an external gear pump and a bent axis piston pump at a flow of 90 liters/minute at 207 bar:

As you’d expect, the more efficient pump requires less drive power for the same output flow and pressure. With a little more math, we can quickly calculate the heat load of each pump:

No surprise that a system with gear pumps and motors requires a bigger heat exchanger than an equivalent (all other things equal) system comprising piston pumps and motors.
