液压阀价格

The working principle of the hydraulic lifting platform is as follows: the machine is installed in the position of the hydraulic cylinder a sensor to control a solenoid directional valve.In the lifting platform in the rise, fall, locking, are to use the O - function of three - way four - way valve to achieve.

The pressure of the hydraulic system of the platform is determined by the load pressure.Speed control flow does not control pressure.That is, the greater the speed of the lifting platform rise faster.If in use, to adjust to the desired height, it should be at the appropriate time to control the direction of the reversing valve.But do not need to adjust the speed, even if you want to adjust the flow rate is generally not by adjusting the speed, but the lifting platform with variable pump or throttle valve to achieve.

The working principle of lifting platform

Lift power unit

Lifting platform with external power as traction, using three-phase power or diesel as power, easy to move, suitable for long-distance work.

By rising button control contactor or absorption, turn on the electric motor power supply, electric motor driven hydraulic pump work, the hydraulic oil in the hydraulic pump pressure under the action of the oil filter, flameproof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, balance valve, explosion-proof valve into the lower hydraulic cylinder, hydraulic oil on the piston, moves the upward movement of the piston rod, the concern about higher lift platform mesa, the oil in the hydraulic cylinder top back of 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. When set to lift platform position, by the stroke switch contactor control circuit power supply, the contactor disconnects, the electric motor power is cut off, and the lifting platform stops at the designated position;Through the down button and relay on unloading loop electromagnetic directional valve, the lift platform under the action of its own gravity and gravity of goods, the hydraulic cylinder piston rod downward movement, the oil in the hydraulic explosion-proof solenoid directional valve to enter the upper cylinder, and the lower cylinder oil return the balance valve, hydraulic control one-way valve, throttle valve, flameproof electromagnetic directional valve back to tank. When to set position, unloading loop is cut off by travel switch electromagnetic directional valve power supply, lift platform in formulating the stop position. In order to make the weight fall is smooth, safe and reliable braking, set the balance valve on back to oil, balance circuit, maintain pressure, make the falling speed is not affected by weight changes, the throttle valveAdjust the flow rate and control the lifting speed. In order to make the brake safe and reliable and prevent accidents, increase the hydraulic control one-way valve, namely the hydraulic lock, to ensure the safety of self-locking when the hydraulic pipeline is unexpectedly burst. Install the overload acoustic control alarm to distinguish overload or equipment fault.
