This hydraulic power unit is specifically designed for medium and small lift platforms. It integrates key components such as a high-pressure pump, AC motor, multi-functional integrated block, hydraulic valves, and fuel tanks into a single compact system. The lifting platform is controlled by an electromagnetic unloading valve, while the falling speed is regulated by an internal balancing valve. A backup manual unloading valve ensures safe operation during power outages. This unit is widely used in stackers, small and medium-sized lifting platforms, and various industrial applications.
The unit is commonly installed in dump trailers and serves as a direct replacement for most power-up or gravity-down systems. Its high-quality starter ensures long-lasting performance and quick starting every time. The motor is built to last, and the tank is specially designed to prevent cracking or leaking under harsh conditions.
Usage Instructions:- Connect the hydraulic power unit and oil cylinder tubing according to the hydraulic principle diagram, ensuring all connections are clean and secure.
- Follow the motor and electromagnetic valve markings to properly connect the AC/DC voltage.
- Test the motor without load, observe any unusual behavior, and gradually increase the load until normal operation is achieved.
Precautions:
- The system pressure is pre-set at the factory. If adjustment is needed, users can adjust it using the knob, but should not exceed the system’s nominal pressure.
- Carefully check the motor and electromagnetic valve connections. Do not attempt to lift or move the unit during installation.
- During initial installation and testing, ensure the internal oil level is adequate. After each work cycle, refill the tank, but avoid overfilling.
- Pay close attention to the electrical characteristics of the motor and electromagnetic valve (AC/DC voltage). Ensure the AC motor casing is properly grounded. Avoid operating the motor without grounding. Keep the motor terminal box waterproof and moisture-proof. During first-time connection, test the motor direction by rotating counterclockwise from the back end. Never allow reverse rotation or no-load idling.
- When filling the hydraulic oil, ensure it is filtered with a precision of at least 25 microns.
- The unit cannot filter impurities inside the hydraulic cylinder, so the cylinder must be cleaned before use. Similarly, all tubing should also be clean to prevent valve failure.
Maintenance Tips:
- Keep the actuators and pipelines clean to prevent dirt from entering the system.
- Maintain the oil level in the tank. Refill after each work cycle, as low oil levels may damage the pump and seals.
- Change the hydraulic oil after 100 hours of operation and replace it every year (1500 hours).
- Hydraulic oil viscosity typically ranges between 22 and 46 cSt.
- Use high-viscosity oil in high-temperature environments and low-viscosity oil in colder conditions.
