What is the cause of the sudden drop in the speed of the hydraulic motor? Dalan hydraulic small series made a summary, for reference only.
The reasons are as follows:
1. The oil supplied by the hydraulic oil pump is insufficient.
2. The pressure of the hydraulic oil pump to input the oil motor is insufficient.
3. The motor power is insufficient and the speed is too low.
4. The filter of the oil suction port is blocked, the oil is too large, or the oil address is insufficient.
5. The oil temperature is too high, causing the viscosity of the hydraulic oil to decrease, the internal leakage to increase, and the efficiency to be insufficient.
6. The joints are poorly sealed and air is mixed.
7. The joints of the oil motor are poorly attached or fastened, causing leakage.
8. The overflow valve fails, the spool valve is trapped by impurities in the valve body, or the damping orifice is blocked, and the pressure regulating spring is broken or loses elasticity.
9. Push the bearing spring of the oil distribution plate to fatigue.
10. The hydraulic system piping is too long and the path is too small, causing too much pressure loss.
11. The axial clearance or radial clearance of the hydraulic oil pump is too large.
12. The one-way valve seat and the steel ball are worn to make the seal malfunction.
How to solve these reasons?
1. Minimize the length of the pipeline, increase the diameter of the tubing and reduce the pressure loss.
2. Repair or replace the motor with higher power.
3. Increase the cooling device, reduce the oil temperature, or replace the oil with higher viscosity, reduce leakage and improve efficiency.
4. Clean the filter, add enough oil or replace the oil with less viscosity.
5. Carefully inspect the joint surfaces and tighten the screws to eliminate leakage.
6. Repair the relief valve, clean the slide valve and damper the small hole, or replace the spring.
7. Replace the support spring.
8. Carefully inspect and tighten the joints to avoid air ingress.
9. Repair and replace the seat and steel ball, make sure the valve seat is in close contact with the steel ball.
