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

If high-pressure leakage exists, remove motor for inspection; if unsolved, notify manufacturer to replace unit. If gear pump seal is loose, replace the gear pump.

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

Check: (1) Electrical connection error - wire correctly. (2) Start switch burned - replace switch. (3) AC contactor burned - replace contactor.

How to resolve excessive system noise?

Check: (1) Air in system - work back and forth to remove air. (2) Coupling issues - reinstall or replace. (3) Motor failure - inspect and replace motor. (4) Extreme pressure operation - 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: (1) Oil level too low - add oil to specified level. (2) Oil viscosity incorrect - use recommended hydraulic oil. (3) Filter screen clogged - clean or replace. (4) Air leak in suction pipe - repair or replace. (5) Valve not closed - clean or replace valve. (6) Emergency button engaged - open auxiliary valve button. (7) Solenoid valve energized causing unloading - check circuit. (8) Motor reverse rotation - reconnect. (9) Relief valve misadjusted - reset pressure. (10) Cou

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

Check: (1) Solenoid valve power - check circuit. (2) Input voltage - ensure standard value. (3) Clogged filter - clean or replace valve core. (4) Damaged electromagnet - check voltage and signal. (5) Blocked throttle/compensation valve - adjust or replace.

Q:How to fix system pressure failure where the cylinder drops while maintaining pressure?

Check: (1) Check valve seal - clean or replace seal. (2) Solenoid/manual valve seal - clean or replace seal. (3) Actuator issue - connect pressure gauge to oil outlet; if normal, the actuator is faulty.

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.
