What should be paid attention to during the use of hydraulic motors? Let Dalan Hydraulic Xiaobian share it with you! Please take note of the following instructions:
1. The hydraulic motor usually allows to work under a pressure of 20%-30% of the rated pressure in a short time, but the instantaneous maximum pressure cannot occur at the same time as the maximum speed.
2. There is a certain limit on the back pressure of the return line of the hydraulic motor. When the back pressure is large, the leaking oil pipe must be set.
3. The maximum torque and maximum speed of the hydraulic motor should not normally occur at the same time.
1 The actual speed should not be lower than the minimum speed of the motor to avoid creep.
2 When the required speed of the system is low, and the motor is not easy to meet the working requirements in terms of speed, torque and other performance parameters, a speed reduction mechanism can be added between the motor and the host it drives.
3 In order to run smoothly at very low speeds, the motor leakage must be constant, with a certain return oil back pressure and oil viscosity of at least 35 °C.
4. In order to prevent cavitation or loss of braking ability of the brake motor working as a pump, it should be ensured that the suction port of the motor has sufficient replenishing pressure.
1 It can be realized by a charge pump in a closed circuit or a back pressure valve in an open circuit;
2 When the hydraulic motor drives a large inertia load, the bypass check valve in parallel with the motor should be set in the hydraulic system to avoid the lack of oil in the inertial motor during the stop.
5. For hydraulic motors that cannot withstand additional axial and radial forces, or hydraulic motors can withstand additional axial and radial forces, but the actual axial and radial forces of the load are greater than the axial force or radial force allowed by the hydraulic motor. For force, consider using a flexible coupling to connect the motor output shaft to the working mechanism. Motors that require low speed operation must be checked for their lowest stable speed.
6. It is necessary to lock the motor for a long time to prevent the load from moving. The spring-loaded hydraulic release mechanical brake should be used on the motor shaft.
7. The hydraulic motor should not be disassembled after failure.
The above points are the matters that should be paid attention to during the use of hydraulic motors. If you have other different opinions, please feel free to discuss them together!
