The lifting column is driven by hydraulic means. Due to long-term operation, mechanical failure is inevitable.
Poor quality of oil pipes or quality problems of hydraulic oil will affect the later use, such as oil pipe burst or oil leakage, especially.
So in addition, what are the reasons for the unstable operation of the lifting column?
1. The electric hydraulic lifting column often fails to detect the center of the lifting position, produces impact noise when rising, and hydraulic cylinder oil leakage. The main reason is that the lifting speed of the lifting hydraulic cylinder is too fast, resulting in an increase in the incidence of failure., Seriously affect work efficiency.
When the operation of the lifting equipment is unstable, the first thing to analyze is the cause of the hydraulic oil flow. The quality of the hydraulic oil is not good, and when there are many impurities or pollutants, it will be blocked, which will slow down.
2. The use of hydraulic pipelines is also very important. At the same time, hydraulic pumps are also one of the important reasons that affect the flow of hydraulic oil.
If the hydraulic pump is used for too long, the failure rate and repair rate will increase. When the lifting speed is reduced, it is necessary to check whether the oil supply speed is stable.
3. The diameter of the cylinder and the flow rate of the hydraulic oil.
The speed of the hydraulic lifting column is negatively related to the section of the cylinder piston rod and positively related to the hydraulic oil flow. The fixed diameter of the cylinder will not change. When the lifting speed slows down, the hydraulic flow should be considered first;
4. In the process of lifting the lifting column, a lifting loop will be formed, and the speed and rigidity of the loop will be analyzed.
The flow into the hydraulic cylinder is the flow through the one-way throttle valve. The throttle valve's throttle port style is related to the viscosity of the hydraulic oil. The greater the speed stiffness of the throttle speed control circuit, the higher the speed stability of the hydraulic circuit.
