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, ...
Design And Operation Of Pumps For Hot Standby Service
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
Pump thermal distortion problems routinely arise in refinery applications where hot fluids must be handled. This is particularly the case when warming up standby pumps. The single stage, double suction configuration, which ...
High Head-Low Flow Centrifugal Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
Centrifugal pumps that fall into a category defined as high head, low flow pumps are discussed. A brief history of these pump types is presented. The principle of operation and performance envelope are addressed. Comparative ...
Rotordynamic Considerations In The Design Of High Speed Centrifugal Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
Operating speeds of multistage pumps tended to increase during the last decade from 4000 to 6000 rpm to 7000 to 10000 rpm, due to new super critical powerplant designs and new conversion processes in the hydrocarbon industry. ...
A New Method For Computing Minimum Flow
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
Appropriate specification of minimum flows is important to avert pump reliability problems. A method is presented for the calculation of minimum flow by allowing a satisfactory margin below the onset of flow recirculation ...
