Elimination Of Cavitation-Related Instabilities And Damage In High-Energy Pump Impellers
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
The suction-stage impeller of a large crude oil pipeline pump was designed by combining quasi-three dimensional flow analysis with current theories to generate an impeller geometry, which was evaluated in a half-size model ...
Measurement And Prediction Of Full Scale Annular Seal Coefficients
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
The accurate prediction of rotordynamic behavior of centrifugal pumps has increased in importance over the last decade, with a steady increase in speed and power concentration. Designing a pump which has acceptable vibration ...
A User's Engineering Review Of Sealless Pump Design Limitations And Features
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
Exxon Chemical like many other petrochemical companies and refineries, is announcing emission plans with a long term goal to achieve continuous emission reduction from the plant sites. Exxon Chemical’s emission plan has ...
Tandem Seals For Near Zero Hydrocarbon Emissions
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
More stringent regulatory limits are being placed on gaseous emissions from pumps handling hydrocarbon fluids. For example, new pumps in the Los Angeles Basin are required to have ear zero emissions. The EPA is proposing ...
Changes In Pump Vibration Levels Caused By The Misalignment Of Different Style Couplings
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
Unacceptable pump vibrations are sometimes caused by the misalignment of the motor to the pump. Pump vibration increases due to misalignment is dependent on the amount of misalignment and the type of coupling used. The ...
Dual Containment Shells - Added Safety For Magnetically Driven Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
Proper function of the shroud is fundamental to the success of the magnetically driven pump. It provides the static seal of the product to the atmosphere without the need for conventional shaft seals. The efficiency and ...
Techniques For Eddy Current Reduction In Magnetic Drives Using Metallic Containment Barriers
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
Magnetic drive systems, using permanent magnets, are a well known transmitting power through a casing or barrier where penetration of that casing is to be avoided. Several magnetically driven pumps are available today which ...
Table of Contents for the Proceedings of the 8th International Pump Users Symposium
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
Analysis Of The Thermal Behavior In The Sealing Cavity Of An Overhung Api Process Pump
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
In recent years, cooling requirements for mechanical seals have become a subject of controversial opinions. While the maximum limiting temperatures of mechanical seals are known and specified by seal manufacturers, the ...
The Texas LoanSTAR Monitoring and Analysis Program: Report to the Monitoring and Analysis Review Committee, August 1991 (Volume II)
