Gas springs can be divided into lift gas spring, lockable gas spring, cabinet gas spring, damper and traction gas spring. Stainless steel gas spring is one of lift gas spring, mostly used in food machinery, medical equipment, military industry.
So how to judge stainless gas springs’ quality?
The gas spring is an industrial accessory that can support, cushion, brake and adjust the angle. The control element and the control unit in the cylinder, if mixed with a mixture of gas and oil liquid, cause a sudden increase in the pressure in the cylinder, so that smooth movement of the piston rod is not easy. When judging the quality of a gas spring, the first thing to consider is the sealing, and the second is the service life. The life is calculated according to the number of times of full expansion, and finally the change of the force value in the stroke.
The magnitude of the change in the value of the gas spring force 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. At the same time, it is also a kind of lifting spring that can save labor, and can be divided into self-locking spring and non-self-locking spring. The self-locking spring works very stable, but the efficiency is not high. On the contrary, the self-locking spring does not work fast, but it is easy to cause problems. It is not difficult to see that the quality of the gas spring is not an absolute value. It is determined according to the environment.
How to choose gas spring?
By adjusting the position of the two support points of the gas spring, the stretch length L and the stroke S of the gas spring are determined, and then the gas spring product series, that is, the diameters of the piston rod and the cylinder are determined according to the calculated F1 force value.
If the gas spring sealing performance is good and the sealing performance is not good, then there will be problems such as oil leakage or air leakage, which may affect its normal use. The service life of gas springs is generally expressed in terms of the number of full expansions. When the number of expansions is large, the service life is long.
Select the gas spring, first consider the sealing performance of the gas spring. If the sealing performance of the gas spring is not good, then some other faults such as oil leakage and air leakage will occur during the use. The accuracy of the gas spring is also very important. The accuracy error cannot be too large. The error values produced by different manufacturers are different, as long as they are within the normal range.
