What is the working principle of the hydraulic lifting platform?

作者: Release Date: 2019-05-06 Author: Click:

What is the working principle of the hydraulic lifting platform? Xiaobian, the official website of Hainan Ventilation Equipment, introduces you.

Lifts are generally divided into mobile lifts, fixed lift platforms, rail-type freight elevators, aluminum lifts, hydraulic lift platforms, and other hydraulic lift platforms based on the movement, structure, and materials.

Although the elevators are classified differently, the working principle is the same. The horseman of Jinan Tianyue Machinery will explain it to everyone.

The working principle of the lift is that the hydraulic oil is formed by a certain pressure by a vane pump. It enters the lower end of the hydraulic cylinder through an oil filter, an explosion-proof electromagnetic directional valve, a throttle valve, a hydraulic control check valve, and a balance valve. The piston moves upward, the lifting platform raises and lifts the heavy object, and the oil return from the upper end of the cylinder is returned to the fuel tank through the explosion-proof electromagnetic directional valve. Its rated pressure is adjusted through the relief valve, and the pressure gauge reading value is observed through the pressure gauge.

When the heavy object is lowered by the electric lifting platform due to gravity, the piston of the hydraulic cylinder moves downward, and the hydraulic oil enters the upper end of the hydraulic cylinder through an explosion-proof electromagnetic directional valve, and the oil returning from the lower end of the hydraulic cylinder passes through a balance valve, a hydraulic control check valve, a joint The flow valve and flameproof electromagnetic directional valve return to the fuel tank. In order to make the heavy objects fall smoothly and the lifting platform is safe and reliable, a balance valve is installed 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 flow is adjusted by the throttle valve to control the lifting of the hydraulic lifting platform speed. In order to make the brake safe and reliable and prevent accidents, a hydraulically controlled one-way valve, that is, a hydraulic lock is added to ensure that the hydraulic pipeline can be safely self-locked when the hydraulic pipeline accidentally bursts. 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, so that the explosion-proof electromagnetic directional valve can be reversed to keep the load raised or lowered, and the amount of time delay can be adjusted to avoid the inflexible lifting caused by the frequent starting of the motor. 3. The machine jam phenomenon prolongs the service life of the lift pump station.

By explaining the working principle of the lift, everyone will understand that the use of the lift is very safe. When the oil spill valve is installed, the pressure will not be adjusted too much, thereby ensuring the smooth lifting of the lift. The hydraulic control check valve is installed to prevent the rapid drop of the lifting platform caused by the burst of the hydraulic oil pipe.
