While gas springs and hydraulic dampers, specialized kinds of springs that utilize gas under compression to exert force, are designed in various sizes and lengths, selecting one depends on two main factors, the required spring force and also the effective stroke of the spring. Application design considerations with the
gas strut mount involves selecting springs with the proper sized cylinder and piston based on the force required for the application. For instance, the trunk lid of a car is sustained by two gas springs on both sides of the lid, that if compressed make a force that’s roughly comparable to the weight of the lid. Similarly for an office chair, the force created by the gas lift needs to be a little higher than the weight with the chair, allowing the consumer to effortlessly move the chair along. Furthermore, to prevent buckling the buckling of the gas springs, the force produced should invariably be in line with its centerline, particularly for a slender gas spring device.

Another point to consider while selecting or designing a gas spring will be the ambient operating temperature, as both extreme hot and cold temperatures affect the operation. The change in temperature affects pressure that a gas spring can exert and therefore the output force. At high temperatures, the seal permeability increases and gas molecules may escape from the seal quicker. They are also designed depending on the performance guidelines that include cold closing and opening efforts, hot opening and closing efforts, self-rise and self-close angle, hump, room temperature, and damping.

Capacity dents, damage, and abrasion should also be ensured while designing the cylinder and also the piston. Special features, including external locking and variable damping, ought to be considered. Safety factors are another major component that should be considered while producing gas springs. As an element of this factor, the suitability with the spring and also the mounting position strength are taken into account. In addition, a second locking mechanism may also be incorporated for safety purposes, if required.

While mounting a gas spring, care needs to be taken to ensure that they are mounted in an upright fashion with the piston rod pointed downwards. This really is to ensure that the rod seal is kept lubricated at all times. If the spring will be mounted at an angle, care ought to be taken to ensure that the level of the lubricating oil is sufficient for the rod seal to be always lubricated during the operation.
