Analyze the working principle of hydraulic freight elevator

The hydraulic lifting freight elevator is mainly a vane pump to form a certain pressure to analyze the working principle of the hydraulic freight elevator. The hydraulic lifting freight elevator is mainly a certain pressure formed by the vane pump, from the oil filter → throttle valve → hydraulic control check valve → balance valve → the lower end of the cylinder, Complete an action. Conversely, the hydraulic freight elevator will work like this. The hydraulic oil enters the upper end of the cylinder from the electromagnetic reversing valve → the lower end of the cylinder → the balance valve → the hydraulic control check valve → the throttle valve → the explosion-proof electromagnetic reversing valve → the fuel tank, we Knowing the working principle of the lift freight elevator, the hydraulic freight elevator schematic diagram will be clear at a glance.
