Question 1

What are the common causes if the motor does not rotate?

Accepted Answer

Check the accuracy of the connection lines.

Question 2

What should I do if the oil cylinder does not rise or rises unsteadily?

Accepted Answer

Check if the oil level is too low and add oil, verify oil viscosity, clean the suction filter screen, check for air leaks in the suction pipe, ensure valves are closed, check the emergency button status, verify solenoid valve energization, check motor rotation direction, reset the relief valve pressure, and inspect the coupling installation.

Question 3

Why might the relief cylinder not descend or descend unsteadily during unloading?

Accepted Answer

Check if the solenoid valve is powered on, verify input voltage, clean or replace clogged filter screens, check for electromagnet damage due to overheating, inspect for blocked throttle or pressure compensation valves, and adjust or replace them.

Question 4

How can I fix the system failing to maintain pressure?

Accepted Answer

Clean or replace the check valve seal, clean or replace the solenoid or manual valve seal, and connect a pressure gauge to the oil outlet to determine if the issue lies with the actuator.

Question 5

What causes oil leakage between the oil tank and valve block?

Accepted Answer

Inspect and replace worn or broken O-rings.

Question 6

What should be done if oil seepage occurs between the motor rear cover and valve block?

Accepted Answer

Remove the motor to inspect high-pressure leaks, and if unsolvable, notify the manufacturer to replace the power unit. Also, replace the loose skeleton oil seal on the gear pump.

Question 7

Why does the motor continue to run after the switch is cut off?

Accepted Answer

Check for electrical connection errors, inspect for a burned-out start switch, or replace a burned-out AC contactor.

Question 8

How can I reduce excessive system noise?

Accepted Answer

Remove air from the system by working back and forth, inspect and reinstall or replace a worn coupling, inspect and replace the motor if failed, and avoid operating under extreme pressure for long periods.
