Automatic lifting column as some of the main places of maintenance equipment, more and more loved by everyone. How to adjust the automatic lifting column is not stable? The following small series to answer.
1. Full-automatic lifting column often has lifting parts that are difficult to test and find negative correlation, impact noise when lifting, oil leakage of hydraulic oil cylinder, etc. The key is that the lifting rate of hydraulic oil cylinder of the lift is too fast, resulting in the improvement of repair rate and serious harm to productivity. The unstable hydraulic lifting platform must be analyzed first, that is, the factors of the total flow of gear oil. The quality of gear oil is not very good, there are many residues, and the blocking rate is very slow.
2. Create a rate stiffness analysis for the lifting control circuit. The total flow rate injected into the hydraulic cylinder, I .e. the total flow rate flowing through the one-way throttle valve, is the total flow rate passing through the overflow valve, the shape of the throttle valve opening of the overflow valve and the viscosity of gear oil. The greater the rate bending stiffness of the throttle valve variable speed control circuit, the better the rate reliability of the hydraulic machine control circuit will be.
3. Hydraulic pipelines are very critical. Hydraulic oil pumps are the key elements that endanger the total flow of gear oil. Hydraulic oil pumps that have been used for too long are also very prone to problems. When the speed of the fully automatic lifting column is very slow, the hydraulic oil should be checked. If the oil supply of the oil pump is interrupted, it is likely to cause accidents and whether the total flow is stable.
4. The diameter of the hydraulic cylinder and the total flow rate of the gear oil. The speed of the full-automatic lifting column is inversely proportional to the cross section of the hydraulic cylinder, which is proportional to the total flow rate of gear oil. The diameter of the hydraulic cylinder is fixed and will not change. When the speed of the full-automatic lifting column is very slow, priority should be given to considering from the perspective of the total flow rate of the hydraulic press.
