What causes the relief cylinder to descend unsteadily during unloading?

Possible causes include solenoid valve power failure, incorrect input voltage, clogged filter screens, damaged electromagnets, blocked throttle valves, or pressure compensation valves.

How to fix system pressure loss or cylinder drop?

Check if the check valve or solenoid valve is sealed and replace oil seals if necessary. Connect a pressure gauge to the oil outlet to rule out actuator issues.

What are the solutions for oil leakage?

Inspect and replace worn O-rings between the tank and valve block, or between the motor rear cover and valve block. If high-pressure leakage persists, replace the entire power unit.

Why does the motor 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 by working back and forth, check and replace worn couplings, 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.

Product Q&A

Q:What is the maximum weight this unit can bear?

Depending on the cylinder diameter and system pressure configuration, it can bear a maximum weight of 90 tons.

Q:What motor power options are available?

Motor power can be customized to 0.8kw, 1.2kw, 1.6kw, 2.2kw, 2.5kw, 3kw, or 4kw.

Q:What voltage does the unit support?

The unit supports DC12V, DC24V, DC48V, DC60V, and DC72V.

Q:How do I troubleshoot if the motor does not rotate?

Check the accuracy of the connection lines.

Q:What should I do if the oil cylinder does not rise or rises unsteadily?

Check if the oil level is too low and add oil, verify oil viscosity, clean or replace the filter screen, check for air leaks in the suction pipe, ensure valves are closed, check the emergency button, verify solenoid valve energization, check motor rotation direction, reset pressure adjustment, and verify coupling installation.
