Solutions for the Digital Machine Tool Industry

1、 Hydraulic pump has no pressure or insufficient pressure

Possible causes: hydraulic pump damage, improper adjustment of inlet valve, oil pump suction of air or insufficient oil.

Solution: Check the hydraulic pump and replace damaged components; Adjust the inlet valve; Remove air or add oil.

2、 Hydraulic cylinder does not move or moves slowly

Possible causes: hydraulic cylinder damage, pipeline blockage, insufficient hydraulic pump pressure, and low hydraulic oil temperature.

Solution: Check the hydraulic cylinder and replace damaged components; Check the pipeline and remove blockages; Check the hydraulic pump and adjust the pressure; Adjust the hydraulic oil temperature.

3、 Hydraulic oil temperature too high

Possible causes: excessive load, oil blockage, pump leakage, insufficient oil volume, high ambient temperature.

Solution: Reduce the load; Remove oil circuit blockages; Replace the internal seal of the pump; Add an appropriate amount of hydraulic oil; Reduce the ambient temperature.

4、 Severe hydraulic oil pollution

Possible reasons: prolonged use, oil leakage, impurities in the fuel tank, etc.

Solution: Replace hydraulic oil; Clean the oil circuit; Replace the filter inside the fuel tank.

5、 Excessive noise from hydraulic pump

Possible causes: Internal damage to hydraulic pump, blocked oil circuit, insufficient oil, etc.

Solution: Check the hydraulic pump and replace damaged components; Remove oil circuit blockages; Increase the amount of hydraulic oil.

In short, the hydraulic system of CNC punching machines is a complex system, and the handling of faults needs to be based on specific situations. In daily maintenance, it is necessary to strengthen the maintenance and inspection of equipment, promptly identify and solve problems, and ensure the normal operation and production efficiency of equipment.
