Hydraulic elevator is widely used in automotive, container, mold manufacturing, wood processing, chemical and other kinds of industrial enterprises and filling production line, meet the demand of the rise and fall of various working height, at the same time can be equipped with all kinds of mesa, cooperate with all kinds of control mode, are characterized by their smooth lifting characteristics of accurate, frequent start, large capacity, effectively solve all kinds of lifting operation difficulties in industrial enterprises, make the production operation.
Fixed hydraulic elevator
The special hydraulic lifting platform used for transporting goods between building floors is mainly used for transporting goods between working floors. Three – dimensional garage and underground garage between the car lift. The hydraulic system of the product is equipped with anti-fall and overload safety protection device. Operation buttons can be set on each floor and the working table of the lifting platform to realize multi-point control. The product structure is firm, the bearing capacity is big, the rise and fall is steady, the installation and maintenance is simple and convenient, it is economical and practical the ideal goods transportation equipment which replaces the elevator between the low floor. According to the installation environment and use requirements of the lifting platform, different optional configurations can be selected to achieve better use effect.
It is mainly through the hydraulic oil pressure transmission to achieve the lifting function, its shear fork mechanical structure, so that the lift has a higher stability, wide platform and higher bearing capacity, so that the upper working range is larger, and suitable for multiple people at the same time. It makes working at height more efficient and more secure.
Working principle of hydraulic elevator
Hydraulic oil made certain pressure vane pump, the oil filter, flameproof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, balance valve into the lower cylinder, the hydraulic cylinder piston upward movement, improve the weight, the upper cylinder oil return by the flameproof electromagnetic directional valve back to the fuel tank, the rated pressure through the overflow valve adjustment, observing the pressure gauge pressure gauge reading values.
The piston of the cylinder moves downward. The hydraulic oil enters the upper end of the cylinder through the explosion-proof electromagnetic directional valve, and the lower end of the cylinder returns to the oil tank through the balance valve, the liquid controlled one-way valve, the throttle valve and the explosion-proof electromagnetic directional valve. In order to stabilize the drop of the weight and ensure the safety and reliability of braking, a balance valve and a balance circuit are set on the oil return circuit to maintain the pressure, so that the drop speed is not changed by the weight. The throttle valve regulates the flow and controls the rise and fall speed. In order to make the brake safe and reliable, to prevent accidents, increase the hydraulic control check valve, that is, the hydraulic lock, to ensure that the hydraulic pipeline can be safe when the accidental explosion of the lock. Installed overload sound alarm to distinguish overload or equipment failure.
The electrical control system controls the rotation of the motor through the explosion-proof button and the reversing of the flameproof electromagnetic directional valve to keep the load up or down, and adjusts the amount of time delay through the “LOGO” program to avoid the influence of frequent start of the motor on the service life.
