What is the principle of scissor lift platform?

  Scissor lift platformWhat are the principles? Here are our company's technical staff to introduce to customers and friends about the scissor lift platform using hydraulic transmission method for aerial work

1. First, the hydraulic oil vane pump constitutes a certain pressure and enters the lower end of the liquid cylinder through the oil filter, flameproof electromagnetic directional valve, throttle valve, hydraulic control check valve, and balance valve, so that the piston of the liquid cylinder moves upward. , Lift the heavy object, return the oil at the upper end of the liquid cylinder to the oil tank through the explosion-proof electromagnetic directional valve, and adjust its extra pressure through the overflow valve, and observe the reading value of the pressure gauge through the pressure gauge.

  

2. Then, the piston of the hydraulic cylinder moves downward (both heavy objects fall). The hydraulic oil enters the upper end of the liquid cylinder through the explosion-proof electromagnetic directional valve, and the return oil at the lower end of the liquid cylinder returns to the oil tank through the balancing valve, hydraulic check valve, throttle valve, and explosion-proof electromagnetic directional valve.
