Analyzing Unacceptable Seal Performance
(Texas A&M University. Turbomachinery Laboratories, 1998)
For many years, acceptable seal performance was defined as “minimal or no visible leakage.” During the last decade, these definitions have changed immensely as government and industry have combined in a massive effort to ...
Reliability Improvements To A High Pressure, High Temperature, Thirteen Stage Charge Pump
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1994)
Reliability of a high pressure charge pump has been a problem for over 20 years. Unplanned unit outages and sometimes fires accompany pump failures. This paper details the joint effort of the OEM and the user to resolve ...
Rotating Equipment Pump Reliability Upgrading Project
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1994)
In 1988, a general performance assessment was undertaken at Shell UK’s Stanlow Manufacturing Complex to review its competitive position in the market place. The review concluded there was a high level of maintenance ...
Continuous Monitoring Of Sealless Pumps - The Next Step
(Texas A&M University. Turbomachinery Laboratories, 1998)
All centrifugal sealless pumps, both canned motor and magnetic drive, should be monitored to determine mechanical condition. In sealless pumps, the pumped fluid is used as the cooling and lubricating medium for the pump ...
Application Guidelines For Pumping Liquids That Have A Large Dissolved Gas Content
(Texas A&M University. Turbomachinery Laboratories, 1998)
A case history is presented pertaining to five (four operating and one spare), 150 hp sealless pumps operating in parallel in a closed loop-65° chilled liquid system. The pumping system is designed to use a liquid refrigerant ...
Understand Progressing Cavity Pumps Characteristics And A Void Abrasive Wear
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
Progressing cavity pumps develop their pumping action by the meshing of the external threads of the elastomer stator and the internal threads of the metallic rotor. The special geometry, as characterized by the different ...
The Road To Reliable Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
A Team Approach To Quality Pump Procurement And Installation
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1994)
There are three factors that will enhance smooth equipment startup, operation, maintenance, and reliability in any new process plant: *Initial pump design and selection *Proper installation *Consistent operational support ...
Centrifugal Pumps Inspection And Testing
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
The general requirements for inspection and testing of centrifugal pumps are presented. The successful completion of inspection and testing verifies pump design and specification compliance prior to release of pump for ...
High Temperature Twin Screw Pumps
(Texas A&M University. Turbomachinery Laboratories, 1998)
High temperature applications present many engineering problems. Thermal growth of piping and vessels, coupled with typically lower viscosities at high temperature, has made centerline mounted centrifugal pumps the primary ...
