The rubber parts can effectively prevent the erosion of the corrosive medium to the inner wall of the rubber parts in the pipelines with high temperature resistance, acid and alkali resistance, and oil resistance, and improve the service life, and the rubber parts have good comprehensive performance. Rubber parts are mainly used for mechanical parts to prevent leakage of liquid and gaseous media under static conditions. In some cases, rubber parts can also be used as dynamic sealing elements for axial reciprocating motion and low-speed rotary motion. Choose different materials to suit it.
Generally, rubber parts should be selected with large cross-sections as much as possible. In the case of the same gap, the volume of rubber parts squeezed into the gap should be smaller than the maximum allowable value for the rubber parts to be squeezed into. For different types of fixed sealing or dynamic sealing applications, the rubber part is a two-way acting sealing element, the initial compression in the radial or axial direction during installation, and its own initial sealing ability. The sealing force generated by the system pressure and the initial sealing force are combined into the total sealing force, which increases with the increase of the system pressure.
