The key to the hydraulic control system of the Jinan hydraulic lifting platform The hydraulic control system of the hydraulic lifting platform is the key to the operation of the entire hydraulic lifting platform, so you must pay great attention to it during production and use. Today we will talk about the steps and precautions of the hydraulic control system of the Jinan hydraulic lifting platform in order to facilitate your further understanding and understanding. When the common Jinan hydraulic lifting platform hydraulic control system is in use, you must tighten the oil return valve knob clockwise, pull the manual reversing valve handle to the 'neutral' position, start the motor to make the system work, and then turn the reversing handle Pull to the 'lifting cage
' position, the hydraulic hydraulic lifting cage platform is lifted. When it reaches the required height, push the reversing handle to the 'neutral' position, the hydraulic lifting platform will stop rising and the motor must be turned off at the same time to work. When descending, loosen the oil return valve, and the hydraulic hydraulic lifting platform can descend by its own weight. On the basis of the hydraulic control system of the hydraulic lifting platform, a set of spare hand pumps are added for use in the absence of power. When using a manual pump, first tighten the oil return valve knob in a clockwise direction, pull the handle to the 'neutral' position, and press the handle to construction lift the hydraulic platform to lift. When lowering, loosen the oil return valve knob and the hydraulic lifting platform will lower by its own weight. At that time, the operation method was when the electric motor or diesel engine was used as the power. Electromagnetic reversing valve hydraulic control system: first press the motor switch, the oil pump is in the unloading state when the oil pump is pumping oil, press the start switch, the electromagnetic reversing valve 1DT works, and the hydraulic lifting platform is lifted. When the required working height is reached, turn off the lifting switch, and you can work. Press the down switch, the electromagnetic reversing valve 2DT works, and the hydraulic hydraulic lifting cage platform descends to the original position by its own weight. The support valve controls the hydraulic system: First, start the motor switch, the motor rotates, the gear pump pumps oil, the cylinder extends, and the hydraulic lifting platform rises; when it reaches the height required for work, press the motor stop button, and the hydraulic hydraulic lifting platform stops lifting, that is It can be operated. When descending, press the solenoid switch button, the Jinan hydraulic lifting platform is connected with the oil return of the oil cylinder, and the hydraulic lifting platform is under its own weight. 141.
