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

If leakage occurs at the high-pressure part of the valve block, remove the motor for inspection; if unsolvable, notify the manufacturer to replace the unit. If the gear pump skeleton oil seal is loose, replace the gear pump.

What to do if the motor continues 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 system noise?

Remove air from the system by working back and forth, check and reinstall or replace a worn coupling, inspect and replace the motor if failed, and 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: low oil level (add oil to specified level), incorrect oil viscosity (use recommended oil), clogged filter screen (clean or replace), air leaks in suction pipe (repair or replace), valves not closed (clean or replace), emergency button status (open auxiliary, close main), solenoid valve energization issues (check circuit), reverse motor rotation (reconnect), improper relief valve installation (reset pressure), or coupling issues (reinstall or replace).

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

Check if the solenoid valve failed to power on, input voltage does not meet requirements, filter screen is clogged, electromagnet is damaged, throttle or pressure compensation valve is blocked, or adjust/replace the valve.

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

Check if the check valve is not sealed (clean or replace seal), solenoid/manual valve is not sealed (clean or replace seal), or connect a pressure gauge to the oil outlet to rule out actuator issues.

Q:What should be done if there is oil leakage between the oil tank and valve block?

Inspect and replace the O-ring if it is worn or broken.
