Gas spring installation and method of judging quality

The piston rod of the gas spring must be installed in the downward position and must not be installed upside down, which can reduce friction and ensure the best damping quality and cushioning performance.

Determining the installation position of the fulcrum is the guarantee that the gas spring can work correctly. The gas spring must be installed in the correct way, that is, when it is closed, let it move over the centerline of the structure, otherwise, the gas spring will often automatically push the door open.

Gas springs should not be subjected to tilting or lateral forces during operation. Not to be used as a handrail.

In order to ensure the reliability of the seal, the surface of the piston rod must not be damaged, and it is strictly forbidden to apply paint and chemical substances to the piston rod. It is also not allowed to install the gas spring in the desired position before spraying and painting.

The gas spring is a high-pressure product, and it is strictly forbidden to arbitrarily analyze, bake, or touch it.

The gas spring piston rod is strictly prohibited to rotate to the left. If you need to adjust the direction of the connector, you can only turn it to the right.

The connection line between the two installation connection points should be as vertical as possible to the rotation centerline of the gas spring when it swings, otherwise, the normal expansion and contraction of the gas spring will be affected, and even jamming and abnormal noise will occur. The selected size should be reasonable, the size of the force should be appropriate, and the stroke size of the piston rod should be left with an allowance of 8 mm.

Judging the quality of a gas spring is mainly from the following aspects: first, it’s sealing, if the sealing is not good, there will be oil leakage, air leakage, and other phenomena during use; secondly, the accuracy, such as the need for 500N For gas springs, the force error produced by some manufacturers does not exceed 2N, and the products of some manufacturers may be far from the actually required 500N; again, the service life, its service life is calculated by the number of times it can be fully stretched; The force value changes during the stroke. Ideally, the force value of the gas spring should remain the same throughout the stroke. However, due to design and processing factors, the force value of the gas spring during the stroke inevitably changes. The magnitude of its change is an important criterion for measuring the quality of a gas spring. The smaller the magnitude of the change, the better the quality of the gas spring, and vice versa.
