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 ...
Guidelines To Maximize Reliability And Minimize Risk In Plants Using High Pressure Process Diaphragm Pumps
(Texas A&M University. Turbomachinery Laboratories, 1999)
Design And Operation Of A Nonpressurized Dual Gas Seal In Light Hydrocarbons
(Texas A&M University. Turbomachinery Laboratories, 1999)
A major producer of ethylene installed and is successfully operating a nonpressurized dual gas seal in liquid methane service. The least reliable pump in the unit was a single stage overhung centrifugal pump in demethanizer ...
A Case History - Improvements To An Existing Cooling Tower Sump And Horizontal Split Case Pumps
(Texas A&M University. Turbomachinery Laboratories, 1999)
In adding a second urea plant in 1974 at a Midwestern nitrogen plant, higher cooling water requirements necessitated the construction of an additional cooling tower. A 130 million Btu/hour cooling tower was installed with ...
How To Justify Machinery Improvements Using Reliability Engineering Principles
(Texas A&M University. Turbomachinery Laboratories, 1999)
For the typical machinery engineer, the difficulties encountered with making reliability improvements lie not with the “mechanics” of improvements, but with justifying the cost of improvements. It is difficult to translate ...
A Cavitation Resistant Hydrostatic Seal For High Pressure Breakdown
(Texas A&M University. Turbomachinery Laboratories, 1999)
A unique hydrostatic throttle bushing concept has been developed and successfully tested. The throttle bushing is based on the concept of typical hydrostatic face seals, but incorporates improvements to minimize cavitation ...
