The working principle of the fully automatic lifting column is like a hydraulic or pneumatic piston, which is the piston principle that we are very familiar with, for example, syringe, jack hydraulic cylinder. The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the liquid cylinder through the oil filter, flameproof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, and balance valve, so that the piston of the liquid cylinder moves upward and lifts the heavy object. The oil return at the upper end of the liquid cylinder returns to the oil tank through the flameproof electromagnetic directional 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 weight drop smoothly and brake safely and reliably, a balance valve is set on the oil return path to balance the circuit and maintain the pressure so that the falling speed is not changed by the weight. The throttle valve adjusts the flow and controls the lifting speed. Hydraulic is more complicated than electric, and its accessories are also more. The internal hydraulic mechanical and electrical integration adopts hydraulic technology in the cavity to achieve integrated sealing. After the pressure oil enters the oil inlet cavity of the motor through the oil distribution shaft, it enters the top of the corresponding plunger cylinder through the barrier-free lifting platform housing groove. The hydraulic force acting on the plunger acts on the eccentric wheel through the connecting rod. Its tangential force. The torque is formed in the rotation of the crankshaft, so that the crankshaft rotates counterclockwise. Due to the different positions of the three plunger cylinders, the magnitude of the torque generated is also different.
The full-automatic lifting column is mainly driven up and down by the pneumatic and electromechanical integration inside the column. The main accessories are electric gas spring and power motor. The electric gas spring and power motor are combined. After energization, the pull rod can be controlled to drive the column. The advantage of this design is that the lifting can be realized through simple control mode, and the product cost will also be reduced a lot. The automatic lifting column is a complete set of miniature hydraulic drive system composed of a miniature motor and an integrated hydraulic cylinder. The system is built into the lifting column through a structural part. Each lifting column is an independent unit, realizing The integration of microcomputer, electricity and liquid. Equipped with emergency release system, in case of power failure and other emergencies, the column can be lowered to open the passage.
