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.

AI-Powered supplier vetting

SummaryThe supplier demonstrates documented quality and service-management procedures, including corrective/preventive actions, complaint handling, finished-product inspection, and supplier-service assessment. It offers broad customization and 3D design services, but reports no new products in the past year. Production evidence is limited to one production line, with no ongoing batch quantity reconciliation; outsourcing procedures exist, while no valid manufacturing-capacity contract with affiliated subcontractors is reported. The supplier has inventory capability and export experience, but no overseas warehouse, showroom, agents, branches, or offline trade-show participation. Financial credibility cannot be established because the provided financial indicators are all zero and no supporting financial context is available.

Supplier typeThe supplier describes itself as a hydraulic-products enterprise focused on quality control, customer satisfaction, and reliable products and solutions. It has self-operated import and export rights and reports that exports represent 41%–50% of total sales, indicating a manufacturer-oriented supplier with international trading capability.

After-Sales capabilityThe supplier has documented complaint-handling and corrective-action procedures, inventory capability, and listed service offerings including debugging, maintenance, repair, training, and equipment installation. However, it has no overseas agents or branches, overseas warehouse, overseas showroom, or reported overseas service countries, limiting evidence of local international support.

Production capacityThe supplier reports one production line, inventory capability, and a standard operating procedure for outsourced manufacturing. It also reports no ongoing batch quantity reconciliation and no valid manufacturing-capacity contract with affiliated subcontractors, creating documented production-control and capacity-assurance weaknesses.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, alongside 3D software design services. This directly supports broad customization capability.

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.
