Electric lifting column as some of the main places of maintenance equipment, more and more loved by everyone. What is the reason for the instability of the electric lifting column? The following lifting column manufacturer Qi Xinlong will give you a good analysis.
1. Hydraulic pipeline
The hydraulic pump is also an important factor affecting the flow of hydraulic oil. Hydraulic pumps that have been used for too long are also prone to problems. When the speed of the electro-hydraulic lifting column slows down, check whether the oil supply of the hydraulic pump is stable.
2. Cylinder diameter and hydraulic oil flow
Lifting column manufacturers tell you that the speed of hydraulic lifting is inversely proportional to the cross-sectional area of the piston rod, and the lifting column manufacturers tell you that the speed of hydraulic lifting is proportional to the flow of hydraulic oil, and the diameter of the hydraulic cylinder is fixed. When the hydraulic lifting speed slows down, the hydraulic flow should be given priority.
3. Rigidity analysis of the speed of the lifting circuit
The flow into the hydraulic cylinder, that is, the flow through the one-way throttle valve, is the flow through the throttle valve, the throttle shape of the throttle valve, the viscosity of the hydraulic oil and other related coefficients. The greater the speed stiffness of the throttle control circuit, the better the speed stability of the hydraulic circuit.
4, the electro-hydraulic lifting column can often appear lifting position to detect the middle position can not be found, lifting impact noise, hydraulic cylinder oil leakage and other phenomena. The main reason is that the lifting speed of the hydraulic cylinder is too fast, which increases the failure rate and seriously influences the production efficiency. The instability research of hydraulic elevator first needs data analysis as an important factor of hydraulic oil flow. The hydraulic oil is of poor quality and has many impurities, which will block and slow down.
