Machine seal parts are a type of component used to seal machines or equipment, typically used to prevent liquid or gas leakage. The main function of machine sealing parts is to maintain the sealing inside the machine, prevent external impurities from entering, and ensure the normal operation of the machine.

Machine sealed components are mainly divided into two types: static seals and dynamic seals. Static sealing is used between components that do not require movement, such as connecting pipes, valves, etc; And dynamic sealing is used between parts that need to be moved, such as pistons, bearings, etc.

The material of machine seal parts is usually made of rubber, metal, plastic and other materials, and different materials are selected according to different usage environments and requirements. Rubber seals have good sealing performance and wear resistance, and are suitable for some special working environments; Metal seals have good resistance to high temperatures and corrosion, and are suitable for working environments with high temperatures and pressures; Plastic seals have good wear resistance and chemical corrosion resistance, and are suitable for some special working environments.
