Hydraulic motor After application for a period of time, it is very likely that the speed will decrease to a certain extent. What on earth will cause the speed of the hydraulic motor to decrease?

Causes:

1. The pump is damaged, the pump casing is overheated and causes noise

2. The pressure regulating valve is tightly closed or the oil supply and return system software is blocked, and some parts are overheated

3. When the valve is opened, it makes a sound or hiss, and some parts are overheated

4. There is too much leakage in the equipped operating valve, the valve chamber is overheated, and it feels very hot when touched

5. The hydraulic motor crankcase has excessive ventilation and leakage, and the single oil discharge pipe has excessive leakage and high oil volume

Solution:

1. Check the condition of ball joint

2. Check the tightness of cylinder piston

3. Check oil viscosity and operating temperature

4. Check the middle surface between the oil baffle and the housing

5. Check the condition between the crankshaft and the rack surface and the sealing condition of the running valve

6. Check whether the oil baffle is damaged, and whether the safety channels of the two oil cavities in the oil hole of the casting are collusive to increase the total flow can certainly increase the speed, but it will more or less endanger its service life. If it is within its maximum power range, there is no problem. If the steam pressure reaches the rated working pressure and the speed is increased, it will exceed the output power range it can bear. Naturally, it will be harmful to the service life of the rotary roller line hydraulic motor, as if you can't eat so much, you will break your stomach. The total flow can only be increased by a relatively limited speed. The speed is increased from 500 to 900. It is proposed to replace the motor with a new model and specification, Cycloid hydraulic motor When the total flow is raised to a certain level, the speed is not easy to rise indefinitely, the internal steam pressure rises, the internal leakage expands, the efficiency drops immediately, or the motor is damaged.
