Lift-related works

Lift-related works:

Elevator Principle: hydraulic vane pump oil from the formation of a certain pressure, by the oil filter, flame proof solenoid valve, throttle valve, check valve, balance valve into the hydraulic cylinder at the bottom, so that upward movement of piston hydraulic cylinder enhance weight, liquid tank top oil return solenoid valve by flameproof back tank, the rated pressure relief valve by adjusting observed by pressure gauge pressure gauge readings.

Hydraulic cylinder piston downward movement (both the weight down). Hydraulic oil by the explosion-proof electromagnetic valve into the liquid tank top, the bottom liquid cylinder oil return by balancing valve, check valve, throttle valve, explosion-proof electromagnetic valve back to tank. In order to weight down a smooth, safe and reliable braking in the back to set the balance valve oil on the road, balanced circuit, to maintain pressure on the rate of decline from weight change, regulate the flow from the throttle to control the speed down.

To enable safe and reliable braking, to prevent accidents, increase the hydraulic control valve, hydraulic lock is to ensure that burst in the hydraulic pipeline accidents when the safety self-locking. Overload alarm installed voice to distinguish overloaded or equipment failure. Explosion-proof electronic control system can control the motor rotation button to flameproof solenoid valve of the commutation, in order to maintain the load raised or lowered, and through the "LOGO" procedure to adjust the amount of time delay, to avoid frequent starting motor caused The movements are not flexible, the phenomenon card machine service life.

Scissors platform
Is supported by scissor-type expansion and folding frame to complete the cargo platform of the lift, its power is through the expansion tank to promote the unfolding and folding scissors. As the retractable tank pump flow rate is determined by the general design of fuel tanks in the very slow pace, the rate of 200mm / minute, and connected with the fuel tank inlet pipe diameter Φ6mm. Case of pipeline rupture, hydraulic oil only from Φ6mm the oil return inlet, so the rate of decline is very slow, it will not cause damage and loss.

Pump hydraulic oil from the leaves of a certain pressure, by the oil filter, flame proof solenoid valve, throttle valve, check valve, balance valve into the hydraulic cylinder at the bottom, so that upward movement of piston hydraulic cylinder to enhance the re- material, liquid tank top oil return solenoid valve by flameproof back tank, the rated pressure relief valve by adjusting observed by pressure gauge pressure gauge readings.
