What should I do if the motor does not rotate?

Check the accuracy of the connection lines.

How to fix unsteady lifting or rising issues?

Check oil level, oil viscosity, filter screen cleanliness, pipe sealing, valve closure, emergency button status, solenoid valve energization, motor rotation direction, relief valve installation, and coupling selection.

What causes the relief cylinder to descend unsteadily?

Possible causes include solenoid valve power failure, incorrect voltage, clogged filters, damaged electromagnets, blocked valves, or improper pressure adjustment.

How to resolve pressure holding failures?

Clean or replace the check valve and solenoid valve seals, or check the actuator by connecting a pressure gauge directly to the oil outlet.

What if there is oil leakage between the tank and valve block?

Inspect and replace the worn or broken O-ring.

What causes the motor to continue running after the switch is cut off?

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

How to reduce excessive system noise?

Remove air from the system, check and replace the coupling, inspect the motor, 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.
