Characteristics of supporting gas spring and selection of evaluation quality:
The supporting gas spring is composed of the following parts: pressure cylinder, piston rod, piston, seal guide sleeve, filler, control elements inside the cylinder and outside the cylinder, and connectors. So today, let's introduce the characteristics and quality evaluation of the supporting gas spring!
Features: The supporting gas spring is a kind of lifting spring that can save labor. It can be divided into self-locking supporting gas springs (such as the bottom lifting of the seat, the back of the boss's chair, etc.), and non self-locking supporting gas springs (such as the lifting support of the trunk and closet door).
To judge the quality of a supporting gas spring, the following aspects should be taken into consideration: first, its sealing performance. If the sealing performance is not good, oil leakage and gas leakage will occur in the use process; The second is accuracy, and the range of its change is an important standard to measure the quality of a supporting gas spring. The smaller the range of change is, the better the quality of the supporting gas spring is, and vice versa.
1、 Locating
Before disassembling the supporting gas spring, it is necessary to find the correct position. The gas spring support rod should be installed in a downward position, and the pile should not be reversed. Therefore, we should ensure its position before disassembling, and then make a simple observation.
It is better to ensure the resistance quality and cushioning performance, and then remove them according to the specific situation. If it is necessary to remove the gas spring because of its failure, do not remove it forcefully to avoid serious problems.
2、 Bit bleed
We can put the air spring on the drill floor first, then find a suitable position, and use a small drill bit to drill holes and deflate. - The initial drilling should not be too large, so we must deflate slowly to avoid some internal faults.
The sound of air bleeding may appear at the moment of drilling, and oil may also be ejected, so we should be cautious and wear protective clothing.
