Automatic lifting column as some of the main places of maintenance equipment, more and more loved by everyone. What is the reason for the natural decline after the automatic lifting column rises? The following lifting column manufacturer Qi Xinlong will give you a good answer.
First, check the hydraulic cylinder, tubing, hydraulic station valve block for oil leakage. The hydraulic cylinder is mainly used to check the upper edge of the exhaust hole and the cylinder. If oil leakage occurs in these two places, the cylinder seal will be damaged. The pipeline is mainly to check whether the joint leaks oil. The valve block is mainly used to check the connection with the valve block. Any oil leakage in any of the above areas will cause the lifting column to slide down.
Secondly, check whether the solenoid valve on the hydraulic pump station is damaged. If the indicator light of the solenoid valve is always on during the lifting of the lifting column, it means that it cannot be locked back to the oil circuit in the event of failure. If this is the case, then the lifting column will not rise too high and the landing is easy to distinguish the fault.
Again, check whether the safety valve has any failure that causes its low pressure to overflow back to the fuel tank, causing the lifting column to slide. This failure rate is low, but not easy to find. If you exclude the above two reasons, you need to check here.
Finally, the lifting column is prone to two factors, the carrying capacity is large, and the control system is complex. First, the lifting column rises to the stop limit switch, so that the electronic control system immediately sends a descending signal, so that the lifting column cannot stop. This usually happens with electronic control systems.
In short, the large load lifting column sometimes increases the electromagnetic ball valve that controls the drop of the hydraulic system. It can play a good pressure holding effect through the solenoid valve, but it needs extremely high purity hydraulic oil. If the hydraulic oil contains impurities that are easily blocked by the ball valve, it will not lock the oil circuit and cause the oil to flow back. This is what we usually call an internal leak. This type of failure will usually lead to a natural decline after the rise, which will affect its normal use.
