This hydraulic power unit is specifically designed for medium and small lifting platforms. It integrates high-pressure pumps, AC motors, multi-functional integrated blocks, hydraulic valves, and fuel tanks into a single compact unit. 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 is also included to handle power failures. This unit is widely used in stackers, small and medium-sized lifting platforms, and various industrial applications.
It comes standard in many dump trailers and serves as a direct replacement for most power-up and gravity-down systems. The unit features a high-quality starter that ensures long life and quick starting every time. The motor is built for durability, and the tank is designed to resist 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 or DC voltage.
- Test the motor without load, observe for any abnormalities, and gradually increase the load to ensure smooth operation.
Precautions:
- The system pressure is set at the factory. If adjustment is needed, users can adjust it using the knob, but must not exceed the system's rated pressure.
- Carefully check the motor and electromagnetic valve connections to avoid incorrect wiring.
- During initial installation and debugging, ensure the internal oil level is sufficient. After each cycle, refill the oil but avoid overfilling.
- Pay close attention to the electrical and electromagnetic valve connection characteristics (AC/DC voltage). Ensure the motor casing is grounded properly and avoid operating without a proper ground. Keep the motor terminal box waterproof and moisture-proof. Check the motor rotation direction when first connecting—should rotate counterclockwise from the back end. Do not allow reverse rotation or no-load idling.
- When refilling 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 thoroughly to prevent valve failure. Tubing should also be kept clean.
Maintenance Tips:
- Keep actuators and pipelines clean to prevent dirt from entering the system.
- Maintain the oil level in the tank. Refill after each work cycle, but avoid overfilling to prevent pump damage and seal issues.
- After 100 hours of operation, replace the hydraulic oil. Replace it again after one year (1500 hours).
- Use hydraulic oil with viscosities of 22 or 46 commonly.
- In high-temperature environments, use high-viscosity hydraulic oil; in low-temperature settings, use low-viscosity oil.
