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 ...
Design And Testing Of Seals To Meet API 682 Requirements
(Texas A&M University. Turbomachinery Laboratories, 1996)
In recent years, manufacturers of mechanical seals have been faced with meeting more stringent leakage requirements along with reliability and extended MTBPM. Regulations by Environmental Protection Agency and standards ...
Torsional Vibration In Pump/Driver Shaft Trains - The Role Of External Damping From Pump Impellers
(Texas A&M University. Turbomachinery Laboratories, 1996)
Consideration of torsional vibration in pump/driver shaft trains has become of increasing importance with the development of electronically controlled variable speed electric motors. Such motors not only provide a static ...
Double Row Angular Contact Ball Bearings In Centrifugal Pumps.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Double row angular contact ball bearings are used extensively in ANSI type end suction centrifugal pumps and other fluid machinery. The double row angular contact ball bearing supports combined axial and radial loads, ...
Abrasive Wear In Pumps - A Tribometric Approach To Improve Pump Life
(Texas A&M University. Turbomachinery Laboratories, 1996)
The reduction of abrasive wear and extension of the endurance of pumps requires a system analysis. Various pump types demonstrate different tribological systems under abrasive wear, which are basically dominated by sliding, ...
Multiphase Gas-Liquid Pumping
(Texas A&M University. Turbomachinery Laboratories, 1996)
Pumping crude oil and gas without prior separation greatly reduces the machinery and platform space required. Multiphase pumps can be located at the surface or subsea and are designed primarily as a) two-screw rotary or ...
Improving Building Energy System Performance by Continuous Commissioning
(Energy Systems Laboratory (http://esl.tamu.edu), Texas A&M UniversityDepartment of Mechanical Engineering, Texas A&M University, 1996)
The term Continuous Commissioning (CC) was first used by engineers at the Energy Systems Lab (ESL) at Texas A&M University to describe an ongoing process which improves the operation of buildings using measured hourly ...
Improved Mechanical Seal For High Pressure Pumps In Severe Abrasive Tailings Services
(Texas A&M University. Turbomachinery Laboratories, 1996)
The cost of high pressure gland water and increasing environmental concerns have made the use of flushless mechanical seals attractive in many slurry applications. One such application exists at Syncrude Canada Lts (SCL). ...
