Cleaning Turbomachinery Without Disassembly, Online And Offline.
(Texas A&M University. Turbomachinery Laboratories, 1995)
Turbomachinery is designed for optimum aerodynamic and mechanical performance at given user conditions. Before shipment, this performance is usually verified on the OEM's test floor, based on specified design conditions. ...
Reciprocating Compressor Valve Reliability Improvements.
(Texas A&M University. Turbomachinery Laboratories, 1995)
The primary improvements made to compressor valve reliability over the past several years are covered. The topics include seat, stop plate, element and spring design and will discuss the advantages and disadvantages of ...
Pad Temperature In High Speed, Lightly Loaded Tilting Pad Journal Bearings.
(Texas A&M University. Turbomachinery Laboratories, 1995)
The principal results from an extensive experimental investigation of the steady state characteristics of tilting pad journal bearings are presented. The conditions examined were primarily concerned with operation at high ...
Experience With Empirical Criteria For Rotating Stall In Radial Vaneless Diffusers.
(Texas A&M University. Turbomachinery Laboratories, 1995)
A seven stage, centrifugal compressor, for gas lift service on a North Sea oil production platform, exhibited subsynchronous shaft vibrations during full load, high density, factory tests. Pressure transducers in each stage ...
Dry Gas Seal Retrofit.
(Texas A&M University. Turbomachinery Laboratories, 1995)
Conventionally lubricated shaft sealing systems have long been known to be unreliable, high in maintenance and in some cases hazardous in centrifugal compressors. Labyrinth sealing systems, while generally low in maintenance, ...
Development And Field Application Of A Single Rotor Design Dry Gas Seal.
(Texas A&M University. Turbomachinery Laboratories, 1995)
Improving centrifugal compressor seal performance and reliability can be accomplished through development of new technology and/or by improvement of existing technology. An improved dry gas lubricating seal of single rotor ...
Experiences In Analysis And Monitoring Compressor Performance.
(Texas A&M University. Turbomachinery Laboratories, 1995)
Evaluations of life cycle costs in typical turbomachinery installations have shown that for reliable machines, energy costs normally far outweigh purchase, installation, and maintenance costs. Experience has shown that ...
An Application Of A Hydrostatic Pressure Lift System For Control Of Variable Thrust Loads.
(Texas A&M University. Turbomachinery Laboratories, 1995)
Thrust bearing failures on older equipment, especially large steam turbines, can be costly problems to remedy. A unique solution to a steam turbine thrust bearing problem that confronted Southern California Edison (SCE) ...
Factors And Preventive Measures Relative To The High Temperature Corrosion Of Blade/Disk Components In FCC Power Recovery Turbine.
(Texas A&M University. Turbomachinery Laboratories, 1995)
Power recovery expander turbines in the Fluid Catalytic Cracking Unit (FCCU) process operate under certain conditions that can adversely affect their performance and operational capability or integrity. For instance, erosion ...
Is The Dry Coupling Really Causing Your Vibration Problem?
(Texas A&M University. Turbomachinery Laboratories, 1995)
From time to time vibration probes pick up high vibration at the coupling location on output shafts. Many times the coupling will then be removed and sent to the shop or to the manufacturer for inspection, repair, and ...
