Application Range Of O-ring

O-ring seals are suitable for being installed on various mechanical equipment, and play a sealing role in static or moving states at specified temperatures, pressures, and different liquid and gaseous media. Various types of seals are widely used in machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, construction machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and various instruments and meters. element. O-rings are mainly used for static sealing and reciprocating sealing. When used for rotary motion seals, it is limited to low-speed rotary seals. The O-ring is generally installed in the groove with a rectangular cross-section on the outer or inner circle to play a sealing role. O-rings still play a good role in sealing and shock absorption in environments such as oil resistance, acid and alkali resistance, grinding, and chemical erosion. Therefore, O-rings are the most widely used seals in hydraulic and pneumatic transmission systems.

The O-ring has its own sealing function and does not need to be adjusted periodically. When used for sliding sealing, the sealing performance can not be affected by the direction of movement. It is small in size and easy to use. Because the sealing ring has a large adaptability, it is suitable for The range is very wide, but it is easy to deform when the pressure peak reaches a certain pressure, and there is the possibility of extruding voids. It is widely used in aviation and hydraulic engineering.
