The speed of Komatsu series accessories cannot reach the specified value

2025-02-27

Even if all the flow control valves are opened, the speed of the hydraulic cylinder cannot be increased, and the Komatsu series accessories are underspeed. There are several reasons for this problem.

1. Insufficient oil supply of the hydraulic pump, poor pressure of the Komatsu PC60-6 hydraulic pump accessories may be caused by wear and tear of internal parts of the hydraulic pump, resulting in a decrease in the pump's volumetric power, poor motor speed, hydraulic pump suction obstruction and suction, and other reasons

2. The system has a large amount of oil leakage, including both external and internal leaks

3. The overflow valve overflows too much

4. Hydraulic cylinder's own working chamber and return oil chamber are in contact with each other

5. Choose hydraulic cylinder underspeed with piston ring seal

6. Severe damage to the inner wall of the cylinder body can cause the hydraulic cylinder to slow down or stop halfway

7. The quality of the hydraulic cylinder device is small, and the PC30 hydraulic pump accessories are insufficient, resulting in insufficient force and speed of the hydraulic cylinder
