How to reduce the loss of hydraulic motor pressure energy

To reduce the pressure energy loss when using a hydraulic final drive motor, first start from the inside and reduce the power loss while reducing the internal pressure loss of the system. To solve this problem, it is possible to improve the pressure loss of the internal flow path of the component, using an integrated circuit and a casting flow path.

To reduce the pressure energy loss when using a hydraulic motor, first start from the inside and reduce the power loss while reducing the internal pressure loss of the system. To solve this problem, it is possible to improve the pressure loss of the internal flow path of the component, using an integrated circuit and a casting flow path. At the same time, it is necessary to reduce or eliminate the throttling loss of the system, minimize the overflow required for non-safety, and avoid the use of a throttling system to regulate the flow and pressure.

In the use of materials, materials made by static pressure technology and new sealing materials can be used, so that the friction loss can be effectively reduced. Maintenance during use is indispensable. Maintaining the hydraulic motor in time to prevent pollution from affecting the life and reliability of the motor. It is necessary to develop a new pollution detection method. Online measurement of pollution should be adjusted in time, and no lag is allowed. Loss caused by untimely processing. Hydraulic final drives need to reduce the pressure energy loss, and manufacturers and consumers need to work together, so that the pressure energy loss can be prevented to a large extent.

Hydraulic motor routine parameters

Working pressure and rated pressure Working pressure: The actual pressure of the input motor oil, the size of which depends on the load of the motor. The difference between the motor inlet pressure and the outlet pressure is called the differential pressure of the motor. Rated pressure: A higher pressure that allows the motor to operate continuously in accordance with the test standards.

1. Working pressure and rated pressure

Working pressure: Enter the actual pressure of the motor oil, the size of which depends on the load of the motor.

The difference between the motor inlet pressure and the outlet pressure is called the differential pressure of the travel motors.

Rated pressure: A higher pressure that allows the motor to operate continuously in accordance with the test standards.

2. Displacement and flow

Displacement: The volume of liquid that needs to be input per revolution of the hydraulic motor without considering leakage. Vm (m3/rad)

Flow rate: The flow rate excluding the leakage is called the theoretical flow rate qMt, and the leakage flow rate is considered to be the actual flow rate qM.

3. Volumetric efficiency and speed

Volumetric efficiency ηMv: The ratio of the actual input flow to the theoretical input flow.

4. Torque and mechanical efficiency

The output power is equal to the input power regardless of the loss of the motor.

Actual torque T: The loss torque ΔT is generated due to the actual mechanical loss of the motor, so that it is smaller than the theoretical torque Tt, that is, the mechanical efficiency of the motor ηMm: equal to the ratio of the actual output torque of the motor to the theoretical output torque.

5. Power and total efficiency

The actual input power of the motor is pqM, and the actual output power is Tω.

The total motor efficiency ηM: the ratio of the actual output power to the actual input power. Please take the physical parameters as the main. https://www.spfinaldrives.com/
