Product Description
Pneumatic seal is the use of compressed air to block the rotation of the shaft clearance, do not make the working medium leakage of the sealing device. In the shell on the processing of circular groove, through the compressed air into the back after the closure of the rotation axis of the gap, to prevent leakage of lubricating oil.
Pneumatic seal has the characteristics of simple structure, but requires a certain pressure of the gas supply, so the consumption of compressed air larger, and the gas pressure than the pressure of the sealing medium 0.03 ~ 0.05Mpa. Pneumatic seal is not limited by speed and temperature. It is usually used for sealing of rotary machinery equipment with little difference in pressure. It is also used for sealing of liquid medium and can also be used for gas medium seal, such as to prevent leakage of lubricating oil in bearing chamber. Sometimes it can be used in combination with labyrinth seals or spiral seals.
