We can see lifts everywhere now, but how much do you know about the structure of lifts? Now the elevator is the most important industry where safety accidents occur. So what kind of elevator can we choose to ensure our safety when working at height? To ensure the safety of working at height, we need to know more about lifts.
The elevator is mainly one of the most important equipment for high-altitude operation. The special hydraulic lifting table product used for transporting goods between building floors is mainly used for transporting goods between various working floors; car lifts in three-dimensional garages and underground garage floors. . This is the main function of the elevator. Lifts are needed to move from low to high places. The working principle of the elevator uses the power system to transfer the loan from the lower place to the higher place. The hydraulic oil is formed with a certain pressure by the vane pump, 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 to lift the weight. The return oil at the upper end of the liquid cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve. Its rated pressure is adjusted by the overflow valve, and the reading value of the pressure gauge is observed through the pressure gauge. The lift has a high stability, a wide working platform and a high load-bearing capacity, which makes the aerial work area wider and suitable for multiple people working at the same time. It makes the aerial work more efficient and more secure.
The hydraulic oil enters the upper end of the liquid cylinder through the anti-type 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.
In order to make the weight fall smoothly, the brake is safe and reliable, a balance valve is set on the return line to balance the circuit and maintain the pressure, so that the falling speed is not changed 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 the hydraulic pipeline can be safely locked when it unexpectedly bursts. Overload sound control alarm is installed to distinguish overload or equipment failure
