Abstract:

The interface instability observed during the operation of dynamic fluid seals continued to be investigate Several methods of suppressing the instability leakage using waster as the seal fluid have been developed. These methods are not dependent on close axial clearances. Metallurgical data on the materials used in the liquid metal test rig have been obtained and the information used to insure proper design of the equipment. Additional data on the welding and heat treatment of the Rex 49 gas bearing shaft material is still being investigated. Analysis of the operating characteristics of the argon gas bearing for the liquid metal test rig has been made with a program on the 7090 computer. Author
