Do you know the principle of elevator?
Lifting principle: The hydraulic oil is formed by the vane pump to a certain pressure, and enters the lower end of the liquid cylinder through the oil filter, explosion-proof electromagnetic reversing valve, throttle valve, hydraulic control check valve and balance valve, so that the piston of the liquid cylinder moves upward. , Lift the heavy objects, the oil return from the upper end of the liquid cylinder returns to the fuel tank through the explosion-proof electromagnetic reversing valve, and its rated pressure is adjusted through the overflow valve, and the reading value of the pressure gauge is observed through the pressure gauge.
The piston of the hydraulic cylinder moves downward (ie, the weight drops). The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic reversing valve, and the return oil at the lower end of the hydraulic cylinder returns to the fuel tank through the balance valve, hydraulic control check valve, throttle valve, and explosion-proof electromagnetic reversing valve. In order to make the heavy objects descend smoothly and the braking is safe and reliable, a balance valve is set on the oil return road to balance the circuit and maintain the pressure, so that the descending speed is not changed by the heavy objects. The throttle valve adjusts the flow and controls the lifting speed.
In order to make the braking safe and reliable and prevent accidents, a hydraulic control check valve, namely a hydraulic lock, is added to ensure safe self-locking in the event of an accidental burst of the hydraulic pipeline. An overload sound alarm is installed to distinguish overload or equipment failure. The electronic control system can control the rotation of the motor through the explosion-proof button to reverse the direction of the explosion-proof electromagnetic directional valve to keep the load rising or falling, and adjust the time delay through the "LOGO" program to avoid the frequent start of the motor. The lifting is not flexible, the machine is stuck, and the service life is prolonged.
