A gas spring is a component with elastic function. It seals high-pressure nitrogen in a certain container, and the external force compresses the nitrogen through the plunger rod. When the external force is removed, the high-pressure nitrogen expands to obtain a certain elastic pressure, which is also the primary consideration when choosing a nitrogen spring. As far as the elastic pressure is concerned, many people will ask why the nitrogen gas spring can still maintain a certain spring elasticity even if it is subjected to a large pressure during the use process. In more professional terms, why is the nitrogen gas spring clearly Compressed, the spring itself still maintains the same elastic force. There are usually two use cases when using, one is independent use, and the other is used in series, which will have different effects on the elastic pressure due to different ways of use.
1. When used independently
When a single nitrogen gas spring is compressed by an external force, the spring force increases with the increase of the effective stroke. For example, a nitrogen gas spring with an initial force of 1000N may have a final force of about 1300N-1500N.
2. When used in series
Because the nitrogen gas inside the nitrogen gas springs connected in series is connected, the pressure is a fixed value set by the controller. At this time, the nitrogen gas spring is compressed after being subjected to external force, and the elastic pressure is constant and unchanged.
So in fact, it is not that the elastic pressure of the nitrogen gas spring remains unchanged, but when it is used in series, the elastic pressure of the nitrogen gas spring remains unchanged.
