Recent Experience With Large Liquid Injected Rotary Screw Process Gas Compressors.
(Texas A&M University. Turbomachinery Laboratories, 1991)
Advances in manufacturing techniques and design enhancements for such components as shaft seals have made it possible for liquid flooded rotary screw compressors to achieve availability, reliability, and overall performance ...
Adaptation Of A Propylene Refrigeration Compressor With Dry Gas Seals.
(Texas A&M University. Turbomachinery Laboratories, 1991)
The retrofit of a 35000 hp, two-case centrifugal, propylene refrigeration compressor with tandem dry gas seals in DuPont's ethylene plant at Orange, Texas, is described. The installation of these dry gas seals is one of ...
Centrifugal Compressor Performance Enhancement Through The Use Of A Single Stage Development Rig.
(Texas A&M University. Turbomachinery Laboratories, 1991)
Despite recent advances in computation fluid dynamics, the complex flows through centrifugal compressor components are still not totally understood. These uncertainties detract from the designer's ability to accurately ...
Fluid Film Bearing Fundamentals And Failure Analysis.
(Texas A&M University. Turbomachinery Laboratories, 1991)
Fluid film bearing technology is presented in this tutorial as it applies to turbomachinery equipment. The focus here is on the practical aspects of fluid film journal bearings, as opposed to theoretical analysis. Failure ...
Procedure For Selecting And Evaluating A Special Purpose Motor.
(Texas A&M University. Turbomachinery Laboratories, 1991)
During recent years, there has been considerable interest in motors. This interest has stemmed from what appears to be an increase in motor problems. As a result of this, along with the need for machinery reliability, ...
The Investigation Of Suitability Of Abradable Seal Materials For Application In Centrifugal Compressors And Steam Turbines.
(Texas A&M University. Turbomachinery Laboratories, 1991)
Clearances between sealing devices of rotating and stationary components of turbomachinery have always been important to engineers in controlling gas leakages. One way of accomplishing this is by the use of abradable seals ...
Fan Laws, The User And Limits In Predicting Centrifugal Compressor Off Design Performance.
(Texas A&M University. Turbomachinery Laboratories, 1991)
The fan laws, particularly what the limits are in their use is described. The derivation is covered very briefly. To help understand some of the fan law uses, centrifugal impeller characteristics are covered, particularly ...
An Integral Balance Piston For Centrifugal Pump Impellers
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
Axial thrust balancing of pressure forces in centrifugal pumps has long been a design challenge for pump engineers. This becomes particularly important in sealless pumps, due to their lack of thrust bearing capacity, and ...
Single Plane Balancing
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
Balancing rotating equipment is a form of correction for things that were either not uniform in material sciences or in assembly of components on a rotating shaft. The single plane balancing procedures are addressed, wherein ...
Solution To Cavitation Induced Vibration Problems In Crude Oil Pipeline Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
An output was increased on the Eat-West crude oil pipeline in Saudi Arabia, increasing shaft seal failures were encountered. These limited the operation of the pipeline. Surveys on site and detailed model tests with flow ...
