The quality of the lifting column hydraulic oil is not good, there are many impurities, but in addition to the following other reasons, it will also lead to slower speed, unstable rise and fall.
1. Composition of lifting hydraulic circuit. Oil pump safety valve, directional valve, directional valve, one-way throttle valve (no throttle valve), lifting cylinder.
2. Cylinder diameter and hydraulic oil flow. The hydraulic lift speed is inversely proportional to the cross-sectional area of the piston rod and inversely proportional to the hydraulic oil flow. When the diameter of the hydraulic cylinder is fixed, when the hydraulic lift speed slows down, the analysis of the hydraulic oil flow should be given priority.
Reduce the output speed of the hydraulic cylinder of the hydraulic lift actuator to a negative number. In order to make the forward number a positive number, a negative sign is added to the formula. When replacing the hydraulic lift, the greater the speed stiffness of the imported throttle speed control circuit, the better the speed stability of the hydraulic circuit.
