Common failure analysis of automatic lifting column!

The automatic lifting column is driven by hydraulic method, so the main factor of the general insensitive lifting column is the hydraulic machine.

The oil pipe plays the role of the pressure of the transport fluid in the hydraulic elevator. If the quality of the oil pipe is poor, it will cause a burst failure of the oil pipe, and the hydraulic oil will also be deteriorated and solidified due to external factors and its own failures, which indirectly leads to oil pipe leakage Oil and air leakage failure.

So what are the other common failures and failure factors that cause unstable operation of the automatic lifting column?

1. The automatic lifting column often has a rising position that is more difficult to detect and cannot find the middle position, there is impact noise when ascending, oil leakage from the hydraulic cylinder, etc .;

This is mainly because the lifting speed of the lifting hydraulic cylinder is too fast, which causes the failure rate to increase and seriously affects the production efficiency. The instability of hydraulic lifts must be analyzed firstly, which is the factor of hydraulic oil flow. The quality of hydraulic oil is not good, there are many impurities, and it will also block and cause slow speed

2. The speed of the electric hydraulic lifting column becomes slow;

It should be checked whether the oil supply flow of the hydraulic pump is stable. This is because the hydraulic pump is an important factor affecting the flow of hydraulic oil. Hydraulic pumps that are used for a long time are also prone to problems.

The diameter of the cylinder and the flow of hydraulic oil cannot be ignored either. The speed of the hydraulic elevator is inversely proportional to the cross-sectional area of ​​the piston rod of the cylinder, and is proportional to the flow of hydraulic oil. The diameter of the cylinder is fixed. When the speed of the hydraulic elevator becomes slower, priority should be given to the hydraulic flow.

Therefore, we usually pay more attention to daily maintenance when using automatic lifting columns, so as to improve the working life of lifting columns, and this is true for any product.
