Reapplication Of An Induction Steam Turbine To Extraction Cogeneration Service.
(Texas A&M University. Turbomachinery Laboratories, 1989)
Reapplication of used power equipment can shorten project schedule and decrease capital cost significantly. The following is a broad overview of the reapplication of an FCC airblower steam turbine to 15 megawatt cogeneration ...
Operating Turbomachinery On Or Near The Second Critical Speed In Accordance With API Specifications.
(Texas A&M University. Turbomachinery Laboratories, 1989)
The question of when is it safe to operate turbomachinery on or near the second critical speed is addressed. A parallel evolutionary progression of the API rotordynamic specifications and rotordynamic analysis capabilities ...
Vibration Assessment Of Variable Speed Vertically Mounted Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
Analytical and experimental assessments of the vibration characteristics are described for two 700 hp, vertically mounted centrifugal service water pumps following their conversion from fixed speed to variable speed ...
An Open Letter To The Pump Industry
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
Every industrial process which underlies our modern civilization involves the transfer of liquids from one level of pressure or static energy to another level, and, as a result, pumps have become an essential part of all ...
Solutions To Abrasive Wear-Related Rotordynamic Instability Problems On Prudhoe Bay Injection Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
Prudhoe Bay produced water injection pumps suffered serious vibration problems and high balance piston leakage a few months after initial startup. Even though initial pump orientation at low water rates was satisfactory, ...
Vertical Diffuser Type Turbine, Mixed-Flow, And Axial-Flow Propeller Pumps - A Brief Overview
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
Vertical diffuser type pumps, their applications, advantages, disadvantages, multistaging, manufacturing, material selection, construction possibilities, operation, and repair are reviewed. Also discussed are semi-open and ...
User Experience With Portable Data Terminals In A Machinery Monitoring Program
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
A description is presented from a user’s viewpoint, of a vibration monitoring program using a portable data terminal (PDT) system. A brief description of these systems is given, followed by an explanation of what they can ...
Characteristics Of The Reciprocating Pump
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
A discussion is presented on the physical differences between centrifugal pumps and reciprocating pumps. The disparities are explained in a nonbiased manner and such knowledge should precede an introduction to reciprocating ...
Condition Monitoring Of Rolling Element Bearings Installed In Centrifugal Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
Monitoring the condition of bearings in centrifugal pumps continues to be an important concern to pump users, especially in critical pump installations. Additionally, pump users are interested in simple, easy to use, ...
Solving The Vibration Problem Of A Vertical Multistage Cryogenic Pump
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1987)
Recent experience in solving the shaft breakage and seal rub problem of a vertical, eight-stage liquid nitrogen pump at a plant site is documented. Several initial field tests conducted to diagnose the vibration problem ...
