What should be done if oil seepage occurs between the motor rear cover and valve block?

Remove the motor to inspect the high-pressure part of the valve block. If the issue persists, replace the entire power unit or replace the loose gear pump skeleton oil seal.

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

This may be due to electrical connection errors, a burned-out start switch, or a burned-out AC contactor.

How can I reduce excessive system noise?

Remove air from the system by working back and forth, check and replace the worn coupling, inspect the motor, or stop operation if the relief valve overflows due to extreme pressure.

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 are the common causes 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 when the motor starts?

Possible causes include low oil level, incorrect oil viscosity, clogged filter screen, air leaks in the suction pipe, unclosed valves, or reverse motor rotation.

Q:What should I do if the relief cylinder does not descend or descends unsteadily?

Check if the solenoid valve is powered, verify input voltage, clean clogged filters, inspect for damaged electromagnets, or adjust blocked throttle/pressure compensation valves.

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

Clean or replace the check valve and solenoid valve seals. If the actuator is the issue, connect a pressure gauge directly to the oil outlet to confirm.

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

Inspect the O-ring for wear or damage and replace it if necessary.
