Reduced lift platform controlled by electromagnetic unloading valve, falling speed is controlled by a bulit-in balancing valve. Back-up manual unlaoding valve is used to power down.It's widely used in stacker, samll and medium-sized lifting platform and various industrial fields. This unit comes standard in many dump trailers and It is a direct replacement for most power-up/gravity-down applications. Its high quality starter ensure long life and a fast starting each time. The motor is built to last, and the tank has been specifically designed to not crack & leak under harsh conditions. According to hydraulic principle diagrams, with clean connecting hydraulic powe unit and oil cylinder tubing. According to the motor and the power of the electromagnetic valve marked characteristics ac, dc voltage is properly connected. Inching motor observe any abnormal phenomenon. In actuators, without load, start the electric, short run test, check whether all the parts run smooothly, determine and correct after loading step by step to normal operation. The factory production of a hydraulic power unit when leaving the factory, the system pressure has been set. If you want to change, the user according to the actual situation on their own through the knob to adjust the system pressure regualting valve, but no more than nominal pressure of the system.
Carefully check the motor and the electromagnetic valve connection. In the installation and debugging for the first time, we must keep the internal fuel tank oil level, after a work cycle, oil tank should be made up, but not be too full. Electrical and electromagnetic valve connection should pay special attention to the supply characteristics ac, dc voltage and has the same sign. Ac power motor shell must be reliable grounding, forbidden ground operation. The motor terminal box note waterprrof, moistureproof.
Connection for the first time, inching motor check direction, from the motor back end, spin to counterclockwise. Absolutely forbidden motor reverse reverse rotation and oil-free idling. When the gas tank hydraulic oil must be filtered, filtration precision is not lower than 25 microns.
Power unit can't filter the impurities inside the hydraulic cylinder. So the hydraulic cylinder internal must clean.
Tubing must also be clean. We must keep the actuators, and pipeline cleaning, prevent dirt from entering the system. We must keep the tank oil level, after a work cycle, proper fill oil. Such as pump suction air will cause the damage of pump and the damage of the seal. 100 hours after the running of hydraulic oil for the first time to join, change the new oil.After a year(1500 hours) to replace a new oil. Hydraulic iol viscosity for 22 and 46 was commonly/s. Working environment temperature high use hydraulic oil of high viscosity, low working environment with low viscosity hydraulic oil. Perfect for Dump Trailers-Lift Gates! Perfect replacement pump for 12VDC controlled hydraulic systems.
