How to handle oil seepage between the motor rear cover and valve block?

If high-pressure leakage occurs, remove the motor for inspection and notify the manufacturer if unsolvable. If the gear pump skeleton oil seal is loose, replace the gear pump.

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

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

How to reduce excessive system noise?

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

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.

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

Possible causes include: oil level too low (add oil), oil viscosity incorrect (use recommended oil), clogged filter screen (clean or replace), air leaks in suction pipe (repair), valve not closed (clean or replace), emergency button issues, solenoid valve energization problems, motor reverse rotation, relief valve installation/pressure issues, or coupling problems.

Q:What if the relief cylinder does not descend or descends unsteadily during unloading?

Check if the solenoid valve is powered on, verify input voltage meets requirements, clean or replace clogged filter screens, check for damaged electromagnets due to overheating, or adjust/replace blocked throttle or pressure compensation valves.

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

Clean or replace the check valve oil seal, clean or replace the solenoid/manual valve oil seal, or check if the cylinder itself is the issue by connecting a pressure gauge to the oil outlet.

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

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