Characteristics Of Pneumatic Seals For Rotating Shafts Of Compressor Equipment
Nov 18, 2022
The pneumatic seal has the characteristics of simple structure, but it requires air supply with a certain pressure. The consumption of compressed air is large, and the pressure of the air source is 0.03-0.05 MPa higher than that of the sealing medium. Pneumatic seals are not limited by speed and temperature. They are usually used for seals of rotating machinery equipment with small differential pressure, liquid media and gas media, such as to prevent the leakage of lubricating oil in bearing chambers. Sometimes it can be used in combination with labyrinth seals or spiral seals.
