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 ...
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 ...
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 ...
Low Cost Reliability Through Operator Involvement
(Texas A&M University. Turbomachinery Laboratories, 1999)
At most industrial facilities, the engineering, maintenance, and operation groups are under great pressure to increase reliability and also reduce costs. This paper discusses the role of operators in achieving low cost ...
Case Study - Increasing The System Flow In An Existing Sump
(Texas A&M University. Turbomachinery Laboratories, 1999)
The status of our country’s infrastructure is a topic that has been discussed at length in the past few years. Aging roads and bridges are no longer capable of meeting the demands of a growing population. They suffer either ...
Double Gas Seal With Coplanar Coaxial Rayleigh Pad Faces For Pump Sealing Applications
(Texas A&M University. Turbomachinery Laboratories, 1999)
There has been a rapid growth in the application of noncontacting double seals with a gas buffer fluid to pump sealing. The advantages of such a sealing arrangement are:
• There is no liquid buffer fluid to maintain or ...
Finding And Eliminating Chronic Pump Failures
(Texas A&M University. Turbomachinery Laboratories, 1999)
A Gulf Coast refinery decided to actively address rising pump maintenance costs and risk of production losses by using accumulated failure data and maintenance costs to identify bad actor pumps, then solving the problems ...
