Abstract:
It is a challenge for sealing technology for seals working under high temperatures,high pressures, great linear speed and long work duration. This paper introduces the applications of new technologies and new concepts used in the world. The development trend of seals of long life, high rotating speed, high temperature or high pressure, and little leakage is discussed. Based on comparing several seal configurations and analizing their advantages and disadvantages, solutions to the motive seal problems are put forward for liquid propellant engines under high temperatures and high pressures.
