Hydraulic lifting column as some of the main places of maintenance equipment, more and more loved by everyone. How to distinguish whether the hydraulic lifting column short circuit? The following small series to answer.
Step 1: Check the lifting column circuit for aging, exposure or damage. Disconnect the power supply, and then through the circuit schematic to measure, according to the size of the measured resistance value, to analyze the fault point.
Step 2: After turning on the power, check whether the indicator light of the lifting column electrical box is working to eliminate the short circuit between the power supplies. At this time, a large short-circuit current will be generated and the melting fuse will be burned. This situation is obvious, so it can be detected and eliminated during circuit analysis.
Step 3: carry out the no-load and load test of the lifting column, and check whether the relay can be connected freely. When the contacts are bonded, the switch will not release continuously. When such a short circuit occurs, a large current is not generated and the fuse will blow. Facilities will not be damaged.
How to reduce the noise of hydraulic lifting column?
The power device of the hydraulic lifting column generally adopts pressure control on both sides to ensure the lifting speed. That is to say, the automatic hydraulic lifting column in the lifting process, is to apply pressure.
When the lifting column is lifted to a certain position, the upper and lower physical limits will be hit on the structure. Qixinlong lifting column uses a foot pad with a certain cushioning elasticity to ensure the reduction of the ultimate impact force, thereby reducing noise.
The upper and lower limit horizontal position, through the utility model patented structure technology, to achieve the upper and lower limit horizontal position. It can increase touch area and reduce noise while ensuring multi-touch. At the same time, this innovative structure also allows the column to rise and fall in the movement, as straight as possible.
In addition, another noise source is the sound of the power plant overflow valve. When the piston rod rises in place, the overflow valve will open, at this time there is a certain overflow valve working sound. This noise cannot be prevented. However, by adjusting the time of the control box time relay to reduce the blocking time, maximum noise reduction can be achieved.
The automatic hydraulic lifting column must have a sound during the lifting process, which cannot be stopped. However, professional hydraulic lifting column manufacturers, from a technical point of view, try to control the sound within an acceptable range, and then give users a better product experience.
