This hydraulic power unit is specially designed for dump trailers. It is integrated by a high-pressure gear pump, DC carbon brush machine, central valve block, cartridge valve, and oil tank. It is a typical single-action principle to rely on the rise of motor power on the decrease of load self-weight. The system can be equipped with a built-in constant speed balance valve and an external adjustable flow valve.There are iron and plastic fuel tanks to choose from.
MAIN FEATURES INCLUDE:
- Single-acting principle: The dump trailer power unit adopts a typical single-acting principle, relying on the motor to energize for lifting, and the deadweight of the load to lower. This design makes the system simple and efficient, easy to operate, and particularly suitable for scenarios that require fast unloading.
- Internal and external flow control options: The system can be equipped with an optional built-in constant speed balance valve to ensure stability during unloading and avoid uneven lifting of the hydraulic system due to load changes. At the same time, an external adjustable flow valve can also be selected to provide greater flexibility. Users can adjust the flow and lifting speed according to actual needs to improve operating efficiency.
- Motor selection: The system is equipped with a DC carbon brush motor, which has high efficiency and a long service life, ensuring the stable operation of the hydraulic system. The motor can provide strong lifting power to ensure that the trailer can run smoothly during unloading.
- Fuel tank material selection: iron and plastic tanks are available. Users can choose the appropriate tank material according to different working environments and load requirements. Iron tanks are suitable for high-load work and have strong durability, while plastic tanks are lightweight and suitable for scenarios with requirements for weight and flexibility.
- Cartridge hydraulic valve design: Cartridge valves provide precise hydraulic control to ensure that the system is more efficient and stable during operation. Whether it is lifting or the load's own weight falling, the system can be accurately adjusted to avoid pressure fluctuations and instability.
This hydraulic power unit is suitable for dump trailers and can provide them with efficient and stable hydraulic support, especially in applications that require smooth lifting and fast unloading, which can ensure smooth operation. The choice of built-in constant speed balance valve and external adjustable flow valve also makes the operation of the hydraulic system more flexible and adaptable to various working conditions.
SPECIAL NOTES
The power unit is an S3 working system and can not operate continuously. It starts in 10 seconds and stops in 90 seconds.
Before installation, ensure that hydraulic components such as oil cylinder, oil pipe, and joint are free of impurities.
The viscosity of hydraulic oil shall be 15- 68st. No. 46 anti-wear hydraulic oil is recommended in summer, and No. 32 low temperature hydraulic oil is recommended in winter.
After starting the operating system for the first time, check whether the oil in the oil tank is sufficient, generally 2 / 3 of the oil tank.
After the system is used for the first 100 hours, the hydraulic oil shall be replaced, and then the hydraulic oil shall be replaced every 3000 hours.
