There are many actuators in the hydraulic system, including hydraulic motors. It converts the hydraulic pressure energy provided by the hydraulic pump into the mechanical energy of its output shaft. At the same time, it can also be called an oil motor. It is used in injection molding machinery, ships, construction machinery, construction machinery, coal mining machinery, etc., but in the process of using hydraulic The motor speed is too slow, so what causes it? How to exclude it? Let us understand it together! To
1. Reasons for the slow speed of hydraulic motor actuators
1. Internal leakage of hydraulic motor;
2. The pump used is leaking;
3. The one-way valve in the oil circuit fails, resulting in oil leakage;
4. The solenoid valve fails and the valve is not fully opened;
5. Excessive load;
6. Caused by improper adjustment of the overflow valve used;
7. The variable mechanism of the oil pump fails, and the flow cannot be increased;
8. Insufficient motor oil;
9. The system oil temperature is too high and the leakage is too large;
10. The filter element is clogged;
Second, the elimination method of the hydraulic motor actuator speed is too slow
1. Replace with a new hydraulic motor;
2. Repair or replace the pump;
3. Repair the failed one-way valve or replace it;
4. Clean or replace the solenoid valve;
5. Reduce the motor load;
6. Readjust the overflow and adjust the component standards;
7. Check and repair the oil pump, or replace with a new pump;
8. Add hydraulic oil to make it reach the standard;
9. Cool the hydraulic oil and maintain the temperature of the oil;
10. Find the reason for the blockage of the filter element and clean it.
The above content is the reason for the slow speed of the hydraulic motor actuator and the troubleshooting method shared by the editor. I hope it will be helpful to everyone.
