How to distinguish the quality of gas spring

  • Detail

How to distinguish the quality of gas spring four elements of gas spring is an airtight product, so we can't see the quality of gas spring from the appearance of the product. We can only see its fine surface workmanship. At the same time, we have carried out cooperation with China Academy of space technology. Generally, the problems will be reflected after three months of use: such as air leakage, oil leakage and serious explosion, It is suggested that the selection of gas spring must first depend on the production capacity and production status of the factory, as well as the development and production experience. For export and batch procurement, it is more important to strengthen their own testing, in case of careless selection, batch product quality problems will occur. It is better to have the authoritative test report of the third party

the quality of a gas spring is judged mainly from the following aspects:

the first is its sealing 7 There are obstacles in the lifting process of the pendulum. If the sealing is not good, oil leakage, air leakage and other phenomena will occur in the use process

the second is accuracy. For example, 500N gas spring is required. The force error produced by some manufacturers is not more than 2n, and the products of some manufacturers may be far from the actual 500N

again, the service life is calculated by the number of times it can be fully retracted

finally, the force value changes during the stroke. Ideally, the force value of the gas spring should remain unchanged throughout the stroke

however, due to design and processing factors, the force value of the gas spring in the stroke inevitably changes (i.e. the sample keeps changing in the jaw, in the jaw, in the parallel section or outside the gauge distance). The range of its change is an important standard to measure the quality of a gas spring ring. The smaller the range of change, the better the quality of the gas spring. Otherwise, the worse
