How to resolve oil seepage between the motor and valve block?

If leakage occurs at the high-pressure part, remove the motor for inspection. If unresolved, replace the entire power unit. For loose skeleton oil seals on the gear pump, replace the pump.

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

Check for electrical connection errors, a burned-out start switch, or a burned-out AC contactor. Correct wiring or replace the faulty components.

What causes excessive system noise?

Noise may be caused by air in the system, incorrect or worn coupling, motor failure, or prolonged operation under extreme pressure. Remove air, reinstall or replace the coupling, inspect the motor, or stop operation when the relief valve overflows.

Product Q&A

Q:What should I do if the motor does not rotate?

Check the accuracy of the connection lines to ensure proper electrical contact.

Q:Why does the oil cylinder not rise or rise unsteadily?

Possible causes include low oil level, incorrect oil viscosity, clogged filter screen, air leaks in the suction pipe, or valve issues. Add oil, use recommended oil, clean filters, repair leaks, or replace valves as needed.

Q:What causes the relief cylinder to descend unsteadily during unloading?

Check if the solenoid valve is powered, if voltage meets requirements, if filters are clogged, if the electromagnet is damaged, or if valves are blocked. Adjust, clean, or replace components accordingly.

Q:How to fix the system failing to maintain pressure?

Inspect the check valve and solenoid valve seals for leaks. If the cylinder itself is not holding pressure, connect a pressure gauge to the oil outlet to diagnose the actuator.

Q:What to do if there is oil leakage between the oil tank and valve block?

Inspect and replace the worn or broken O-ring located between the oil tank and valve block.
