Metal Bellows Mechanical Face Seals For High Performance Pump Applications
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
Metal bellows seals have been steadily gaining wider acceptance in process and general industrial pump applications. This paper discusses design criteria and advantages of metal bellows seals, and attempts to define ...
New Developed Multistage Variable Speed Drive (MSVD) Of High Economy For The Speed Control Of Pumps With Power Up To 40,000 HP
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
The multistage variable drive, called MSVD, the latest development of a hydrodynamic mechanical drive system is presented. The special characteristics are high efficiency, excellent reliability, and availability, which are ...
Upstream Pumping: New Developments In Mechanical Seal Designs
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
Conventional mechanical seals are arranged to prevent leakage from a high pressure source. When leakage occurs, it is expected to be from the high pressure area to the lower pressure surroundings. The basic concept of the ...

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 ...
