Pneumatic seal (English And Pneumatic seal) is the use of compressed air to block the gap of the rotating shaft, does not make the working medium leakage sealing device called pneumatic seal. (As shown in Figure 1-1.) The East Seal seal tells you that... The annular groove is formed on the pneumatic seal housing 1 and the clearance of the rotary shaft 2 is blocked by the compressed air to prevent leakage of the lubricant.
What is a pneumatic seal? Figure 1-1 What is a pneumatic seal?
Pneumatic sealing has the characteristics of simple structure, but requires a gas source with a certain pressure, the consumption of compressed air is large, and the pressure of the gas source is 0.03-0.05 MPa larger than the pressure of the sealing medium. Pneumatic seals are not limited by speed and temperature. They are usually used for seals of rotating machinery with low differential pressure. They are used for sealing in liquid media and can also be used for sealing with gas media, for example, to prevent the leakage of lubricating oil in bearing chambers. It can sometimes be used in combination with labyrinth seals or screw seals.
