A gas spring is a part that can realize functions such as support, buffering, braking, height and angle adjustment. In construction machinery, it is mainly used in covers, doors and other parts.
The gas spring is mainly composed of a piston rod, a piston, a sealing guide sleeve, a filler, a pressure cylinder and a joint. The pressure cylinder is a closed cavity, which is filled with inert gas or oil and gas mixture, and the pressure in the cavity is several times the atmospheric pressure. times or dozens of times. When the gas spring acts, the pressure difference existing on both sides of the piston is used to realize the movement of the piston rod. Gas springs have different structures and types to meet different needs. Compression gas springs are mainly used in construction machinery. This type of gas spring mainly plays a supporting role and has only the shortest and longest working positions. stop on its own.
