Lifting column as some of the main places of maintenance equipment, more and more loved by everyone. What are the unstable factors that the lifting column encounters during operation? The following is a small series for everyone to answer.
1. The electric hydraulic lifting column often has the phenomenon that it is difficult to detect the rising position, the middle position cannot be found, the impact noise when rising, and the oil leakage of the hydraulic cylinder. The main reason is that the lifting speed of the lifting hydraulic cylinder is too fast, resulting in an increase in failure rate and serious Affect production efficiency;
2. The diameter of the oil cylinder and the flow rate of the hydraulic oil. The speed of the hydraulic lift is inversely proportional to the cross-sectional area of the cylinder piston rod, and is proportional to the hydraulic oil flow. The diameter of the cylinder is fixed. When the speed of the hydraulic lift is slow, priority should be given to the hydraulic flow;
3. Establish a speed rigidity analysis for the lifting circuit. The flow rate into the hydraulic cylinder, that is, the flow rate through the one-way throttle valve, is the flow rate through the throttle valve, the throttle shape of the throttle valve and the viscosity of the hydraulic oil. The greater the speed rigidity of the throttle speed control circuit, the better the speed stability of the hydraulic circuit;
4, hydraulic lift instability is the first to analyze the hydraulic oil flow factors, hydraulic oil quality is not good, there are a lot of impurities, will also lead to slow blockage;
5. The hydraulic pipeline is also very important. The hydraulic pump is also an important factor affecting the hydraulic oil flow. The hydraulic pump that has been used for too long is also prone to problems. When the speed of the electric hydraulic lifting column slows down, check the hydraulic pump oil supply flow. Is it stable.
