Using Fault Trees To Determine The Root Cause Of Rotating Equipment Failures
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)
The great value of using multidisciplinary task groups to conduct root cause failure analyses (RCFA) on pump and rotating equipment failures is discussed. The RCFA method offers its users a structured means of achieving ...
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 ...
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 ...
Selection Of Lube Oil Systems Components For Process Pumps And Auxiliaries (External, Pressurized)
(Texas A&M University. Turbomachinery Laboratories, 1999)
Lube oil systems are utilized in rotating process equipment to lubricate and cool hydrodynamic bearings. These systems are essential to the life and maintenance free operation of the process equipment. Dependable performance ...
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 ...
Pump Life-Cycles And The Internet Utilizing Technology To Improve Pump Reliability
(Texas A&M University. Turbomachinery Laboratories, 1997)
Information technology, specifically computer mediated communication (CMC), will revolutionize the pump industry, from selection through installation, operation, and maintenance. There will be winners and losers. It will ...
The Application Of Computer Simulation And Real-Time Monitoring To Minimize The Pressure Pulsations In Complex Pumping Systems
(Texas A&M University. Turbomachinery Laboratories, 1997)
Chemical and process plants usually contain numerous valves and pumps in a complex network of pipe runs. Plant design and pump selection are usually based on steady state design conditions. However, the opening or closing ...
Replacement Of The Boiler Feedpumps During The Retrofit Of The 500 Mw Units At A German Power Station
(Texas A&M University. Turbomachinery Laboratories, 1997)
The Janschwalde Power Station consists of six 500 MW units that were commissioned between 1981 and 1989. These units, which were equipped with turbo feedpumps manufactured in Russia, had an average efficiency of only 78 ...
