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 eliminate excessive system noise?

Remove air from the system by working back and forth, check and replace worn couplings, inspect the motor, or avoid operating under extreme pressure for long periods.

What is the lead time for orders?

Peak season lead time is one month, while off-season lead time is within 15 workdays.

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 wiring.

Q:Why does the oil cylinder not rise or rises unsteadily?

Possible causes include low oil level, incorrect oil viscosity, clogged filter screen, air leaks in suction pipe, unsealed valves, or incorrect solenoid valve energization.

Q:What should be done if the relief cylinder does not descend?

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

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

Clean or replace the check valve and solenoid valve seals. Connect a pressure gauge to the oil outlet to rule out actuator issues.

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

Inspect and replace worn or broken O-rings at the connection points.
