A STUDY IN THE FIELD OF FLUID SEALS FOR HIGH SPEED ROTATING EQUIPMENT

Abstract

Many types of seals have been designed for use in reciprocating or rotating machines. In recent years, particularly in military applications, the sealing problem has become complex. High contact speeds, extreme temperatures, and superpressures have presented the designer with some challenging problems. The seals for new applications usually are developed by extrapolating data from previous designs. Most of the recent investigations have been experimental evaluations of new materials. The wear rate, leakage, and frictional drag of the material are observed over a range of speeds, temperatures and pressures. There is little evidence in the literature of analytical studies that pertain to dynamic fluid seals. A few types, such as the Labyrinth Seal, have a well developed theoretical analysis. (Author)
