Working principle of hydraulic lifts
Aug 15, 2017

Hydraulic elevator is composed of tank, hydraulic gear pump, one-way valve, solenoid valve and hydraulic cylinder. Start the hydraulic oil gear pump hydraulic oil tank along the pipeline pump to the hydraulic cylinder piston in the hydraulic cylinder pressure continuously, the (even implantation surface) rises, stop the pump fluid, a one-way valve to prevent oil return, a plunger in the way up; down, simply connect the solenoid valve to open the valve to fluid, oil return tank, hydraulic cylinder pressure, piston down.

The hydraulic lift working process of hydraulic oil: a certain pressure by the vane pump, the oil filter, explosion-proof solenoid valve, throttle valve, hydraulic control valve, balance valve into the cylinder at the lower end of the piston cylinder upward movement, lifting hydraulic cylinder, the upper oil return by flameproof electromagnetic the valve back to tank, the rated pressure is adjusted by the overflow valve, the pressure gauge observation of pressure gauge readings. The piston of the cylinder moves downward (both weights fall). The hydraulic oil enters the upper end of the liquid cylinder through the explosion-proof electromagnetic reversing valve, and the lower end of the liquid tank is returned to the oil tank by the balance valve, the hydraulic control check valve, the throttling valve and the flame-proof electromagnetic reversing valve. In order to make the weight drop steadily, the brake is safe and reliable, the balance valve is installed on the oil return road, the balance circuit is used to keep the pressure, and the falling speed is not changed by the heavy load. The flow rate is controlled by the throttle valve, and the speed of lifting and lowering is controlled. In order to make the brake safe and reliable, and prevent accidents, the hydraulic control check valve is added, that is, the hydraulic lock ensures that the hydraulic pipe can be locked safely when it bursts unexpectedly. An overload sound control alarm is installed to distinguish between overload or equipment failure. Rotating electrical control system by SB1 - SB6 explosion-proof button to control the motor, explosion-proof electromagnetic valve commutation, to keep the load up or down, and the "LOGO" program to adjust the time delay, avoid frequent starting to affect the service life of motor.

The classification and characteristics of mobile hydraulic lifts: 1, hydraulic lifting platform can be divided into: four wheel mobile, two wheel traction type, car modification, car battery, auxiliary self-propelled, lifting height from 4 meters to 18 meters. This series of products load is divided into 0.1 to 0.8 tons, can also be customized according to user requirements, the maximum load of up to 10 tons. 2 、 hydraulic lifting platform widely used in industrial and mining enterprises workshop maintenance, municipal construction, Gaestgiveriet Hotel decoration, quality and reliable, perfect performance. 3, users can choose the power mode and configuration according to their own scope of use: the power system includes: battery DC power supply, single-phase or three-phase power supply, diesel engine. Second, walking: auxiliary self-propelled, two wheel traction, self drive, as well as car modification type. Leg: mechanical leg, hydraulic leg, ordinary hand leg, pull leg. Control system: explosion proof electric control system, remote control system and PIC control system. The hydraulic pump station: domestic lifting platform special pumping station, pumping station and Italy imported for protection device: organ type, mesh type, plate type seal.

The hydraulic lift is mainly through the hydraulic oil pressure drive so as to realize the function of lifting fork, its mechanical structure, so that the lift lifting a higher stability, wide working platform and high bearing capacity of the high operating range larger, and is suitable for people at the same time as the industry. It makes aerial work more efficient and safer.
