The working principle of electric fully automatic lifting platform car

The production technology of the electric fully automatic lifting platform car is very mature now, and we have rarely had low-level quality problems when using it, but in order to better cooperate with the use of the machine, let me simply understand its working principle.

When the lifting platform is rising, the hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic 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 hydraulic cylinder Move upwards to lift heavy objects. The oil returned from the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic reversing valve. The 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 (that is, the weight falls). The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the oil returned from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control check valve, throttle valve, and explosion-proof electromagnetic directional valve.

In order to make the weight drop smoothly and the brake safe and reliable, a balance valve is installed on the oil return line to balance the circuit and maintain pressure so that the descending speed is not affected by the weight, and the flow rate is adjusted by the throttle valve to control the lifting speed.

In order to make the brake safe and reliable, and prevent accidents, a hydraulic control check valve, that is, a hydraulic lock, is added to ensure that it can lock itself safely when the hydraulic pipeline bursts accidentally. An overload sound-activated alarm is installed to distinguish overload or equipment failure.

After we have a certain understanding of the basic working principle of the fully automatic lifting platform truck, we need to combine this knowledge to carry out the work reasonably during the operation process, so that the platform truck can be delivered in the best working state.

The above is the lifting platform manufacturer to share with you, if you have any questions, please call for consultation.
