Dry Gas Compressor Seals
(Texas A&M University. Turbomachinery Laboratories, 1988)
Dry gas seals can eliminate some of the conventional problems associated with seal oil systems. Increased safety, lowered maintenance and improved reliability are key considerations for retrofitting with gas seals. ...
Full Fluid Film Face Seals
(Texas A&M University. Turbomachinery Laboratories, 1988)
The basic types of seal face lubrication are described and the basic design concepts and deflection analysis are discussed. Present field installations are presented, along with operating conditions and common problems ...
Vibration Problems Of Large Vertical Pumps And Motors
(Texas A&M University. Gas Turbine Laboratories, 1980)
A large vertical pump with its associated motor driver constitutes a very complex dynamic system. The apparent simplicity of the visible cantilever portion of the machine belies the complex interaction of the unit with its ...
Alignment Using Water Stands And Eddy Current Proximity Probes
(Texas A&M University. Gas Turbine Laboratories, 1980)
This paper covers one of seven techniques in alignment being presented at an alignment tutorium at Texas A&M University’s Ninth Turbomachinery Symposium. The specific procedure will be covered only, without delving into ...
Lateral Vibration Reduction In High Pressure Centrifugal Compressors
(Texas A&M University. Gas Turbine Laboratories, 1980)
Recent designs of high and medium pressure centrifugal compressors show a well-behaved response to forced vibration and an adequate margin to self-excited vibration. This can only be achieved by an extensive rotor dynamic ...
High Speed Balancing Procedures
(Texas A&M University. Gas Turbine Laboratories, 1980)
The paper describes elastic balancing procedures and experimental results for turbomachine rotors. The commonly known criteria of static and dynamic balancing no longer apply in this case. The rotating elements are balanced ...
