HydraulicLifting columnA certain pressure is formed by the vane pump, and enters the lower end of the liquid cylinder through the oil filter, flameproof electromagnetic reversing valve, throttle valve, hydraulic control one-way valve, and balance valve, so that the piston of the liquid cylinder moves upward and lifts heavy objects. The oil return at the upper end of the liquid cylinder returns to the oil tank through the flameproof electromagnetic reversing valve. Its rated pressure is adjusted by the overflow valve, and the reading value of the pressure gauge is observed. The piston of the liquid cylinder moves downward (both the weight drops). The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, the hydraulic control one-way valve, the throttle valve and the explosion-proof electromagnetic directional valve. In order to make the heavy objects fall smoothly and the braking is safe and reliable, a balance valve is set on the oil return road to balance the circuit and maintain the pressure so that the falling speed will not be changed by the heavy objects. The throttle valve is used to adjust the flow and control the lifting speed. In order to make the brake safe and reliable, prevent accidents, add hydraulic control check valve, that is, hydraulic lock, to ensure that the hydraulic pipeline can be safely self-locking when the accident burst.
The pneumatic lifting column is mainly installed centrally, and the control box shares the power unit for unified control. A control box can drive and control up to 8 lifting columns, saving system costs for users. The lifting speed of the pneumatic full-automatic lifting column can be actively adjusted by the control box according to the requirements, and the fastest response speed is less than 1 second, which fully meets the control requirements of high-frequency entrances and exits and high-safety emergency channels, and supports movement change to prevent accidents. The pneumatic automatic lifting column system does not need strong electric construction, and the power supply mode is more environmentally friendly, and the safety and reliability are relatively high. Electronic control, automatic lifting; unified control, centralized power and control units, easy to maintain; use air as power supply, especially environmentally friendly; fast response speed, support movement change direction; prevent strong current pipeline construction, high safety; provide higher Combination cost performance.
