Design Considerations And Application Guidelines For Pumping Liquids With Entrained Gas Using Open Impeller Centrifugal Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
The proper selection of a centrifugal pump for liquid and gas (two phase) mixtures, is highly dependent on the amount of gas and the characteristics of the mixture. The presence of entrained gases will reduce the output ...
Development Of A Magnetic Bearing, API Process Pump With A Canned Motor
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)
A new class of pumps has been developed where both end face seals and contacting bearings are eliminated. The objective is to provide a sealless pump with long life bearings meeting the duty requirements of API Standard ...
Magnetically Driven Centrifugal Pumps Eliminating Seal Problems In Refinery And Chemical Processing Plant Equipment
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
Centrifugal pump design plays an essential role in the safe operation of any refinery or chemical processing plant. In analyzing the performance of centrifugal pumps, pump operating time to failure is almost always limited ...
Pump Rotor Critical Speeds Diagnosis And Solutions
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
Delmarva Power Indian River Power Station’s Unit 4 has had boiler feed pump reliability problems since startup in 1980. The pump has been rebuilt nine times with post overhaul operability ranging from 30 minutes to 16 ...
New Developments In Standby Seals For Applications For Environmental Sensitive Duties
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)
Over the years, close attention has been paid in process facilities to the pumping of light hydrocarbons. Leakage of these products can and do cause environmental and health threatening situations. Since attention has been ...
Vane Pass Vibration - Source, Assessment, And Correction - A Practical Guide For Centrifugal Pumps
(Texas A&M University. Turbomachinery Laboratories, 1999)
With the ever-increasing use of hand held vibration analyzers, data collectors, and predictive maintenance programs, a more complete understanding of vibrations is ever more important. This tutorial treats one of the most ...
The New Hydraulic Institute Pump Intake Design Standard
(Texas A&M University. Turbomachinery Laboratories, 1999)
A balanced committee of users, designers, researchers, and pump manufacturers has produced a revised Hydraulic Institute Pump Intake Design Standard that is considerably different from the existing standard and more ...
Pump Reliability And Efficiency Increase Maintenance Program - Utilizing High Performance Thermoplastics
(Texas A&M University. Turbomachinery Laboratories, 1999)
At a major oil products refinery, an aggressive effort has been ongoing to improve centrifugal pump reliability and efficiency. Working closely with a manufacturer of high-grade thermoplastics, the company has developed ...
High Pressure Noncontacting Mechanical Seal For API Applications
(Texas A&M University. Turbomachinery Laboratories, 1999)
Since the introduction of noncontacting, gas lubricated, dual pressurized mechanical seals for process pumps over five years ago, and they have primarily been applied to ANSI pumps and other applications where the barrier ...
How To Extend The Life Of Your Boiler Feed Pump
(Texas A&M University. Turbomachinery Laboratories, 1999)
Six topics that should extend the life of a boiler feedpump will be described in detail. These topics will explore both operational and maintenance techniques that, when instituted, have been shown to extend the useful ...
