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

If leakage is at the high-pressure part, remove the motor for inspection or notify the manufacturer to replace the unit. If the skeleton oil seal on the gear pump is loose, replace the gear pump.

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

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

What causes the system noise to be too loud?

Possible causes include air in the system (work continuously to remove), incorrect or worn coupling (reinstall/replace), motor failure (inspect/replace), or operating under extreme pressure for too long (stop when 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.

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

Possible causes include: low oil level (add oil), incorrect oil viscosity (use recommended oil), clogged filter screen (clean or replace), air leaks in suction pipe (repair), valve not closed (clean/replace), emergency button status (open/close), solenoid valve energization issue (check circuit), motor rotation direction (reconnect), relief valve installation (reset), or coupling issues (reinstall/replace).

Q:What causes the relief cylinder to not descend or descend unsteadily during unloading?

Check if the solenoid valve is powered on, if input voltage meets requirements, if filter screens are clogged (clean/replace), if the electromagnet is damaged (check voltage/signal), or if throttle/pressure compensation valves are blocked (adjust/replace).

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

Check if the check valve is sealed (clean/replace seal), if solenoid/manual valves are sealed (clean/replace seal), or connect a pressure gauge to the oil outlet to rule out actuator issues.

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.
