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 ...
Planning, Preparation, And Implementation Of Turbomachinery Turnarounds.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Anyone involved in overhauling equipment during a scheduled
turnaround knows the importance of having the right people and
the right tools available in the right places at the right time.
Obviously, the orchestration ...
Turbine Overhaul Frequency Time Or Performance Based?.
(Texas A&M University. Turbomachinery Laboratories, 1996)
How long should a turbine run before it is disassembled for inspection and overhaul? This question is increasingly important in today's environment of reduced maintenance and turnaround costs. Many aspects of the degradation ...
Options For Low Speed And Operating Speed Balancing Of Rotating Equipment.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Most turbomachinery users refer to bearing vibration as one of
their major indicators of a successful repair. Frequently heard are
such comments as "we could not even tell the machine was
running." The single most ...
A Mathematical Formalism For Flexural Diaphragm Fatigue Life And Reliability Evaluation.
(Texas A&M University. Turbomachinery Laboratories, 1996)
A mathematical formalism is presented for flexural diaphragm fatigue life and reliability evaluation. The use of this formalism enables the diaphragm designer to match a customer's requirements for life and reliability, ...
A Systematic Approach To Case Recertification.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Turbomachinery life expectancy, economic conditions, and plant capacity enhancements have created a need for vintage compressors to be reevaluated and re-engineered for operational parameters that may not have been ...
Design Improvements Enhance Dry Gas Seal's Ability To Handle Reverse Pressurization.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Within the past three years, refrigeration compressors operating intermittently at subatmospheric pressures have experienced two dry gas seal failures which have been attributed, either all or in part, to reverse pressurization ...
Thrust Bearing Analysis, Optimization, And Case Histories.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Babbitted oil film thrust bearings as used in industrial turbomachinery
are discussed. The majority of the presentation covers tbe
higher performance tilting pad thrust bearings as found in most
critical rotating ...
Application Of High Speed And High Performance Fluid Film Bearings In Rotating Machinery.
(Texas A&M University. Turbomachinery Laboratories, 1994)
Some of the critical parameters in the design and application of high performance fluid film bearings are emphasized. The limitations and problems associated with high speed and highly loaded bearings will be discussed. ...
Centrifugal Compressor Application Sizing, Selection, And Modelling.
(Texas A&M University. Turbomachinery Laboratories, 1994)
The objective here is to build on the fan law paper presented at the Twentieth Turbomachinery Symposium [1]. The centrifugal sizing and modelling tutorial draws on the pseudo compressor stage curves presented in the fan ...
