Centrifugal Pump Specification And Selection - A System's Approach
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
Proper pump specification and selection results in the best pump being purchased for the required service. Economic considerations may meant that “best” is not always the most efficient, best hydraulic fit or most expensive. ...
Face Seal Balance Ratio Selection For Two Phase Single And Multicomponent Mixtures
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
It is well known that the fluid pressure distribution between the faces of a mechanical seal greatly affects seal performance. In cases where a sealed fluid changes phase from liquid to vapor as it leaks across the seal ...
Reliability And Future Development Of High Pressure Diaphragm Pumps For Process Service
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
The aim of pump development in recent years has been mainly reliability, safety, low maintenance, and the avoidance of dangerous leakages. For years, more and more rigid regulations against pollution and for better safety ...
Pump Baseplate Installation And Grouting
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
Methods used by the author to level and epoxy grout pump baseplates. The methods used are not the only way pumps can be installed, but if followed, will ensure a 100 percent void free grout job. Execution of the leveling ...
A New Computer Program For Pump Rotordynamic Analysis
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
A new computer program for pump rotor analysis has been developed to improve the accuracy of critical speed, stability, and response calculations for multistaging centrifugal pumps. The program capabilities include: (1) ...
Metal Bellows Mechanical Face Seals For High Performance Pump Applications
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
Metal bellows seals have been steadily gaining wider acceptance in process and general industrial pump applications. This paper discusses design criteria and advantages of metal bellows seals, and attempts to define ...
New Developed Multistage Variable Speed Drive (MSVD) Of High Economy For The Speed Control Of Pumps With Power Up To 40,000 HP
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
The multistage variable drive, called MSVD, the latest development of a hydrodynamic mechanical drive system is presented. The special characteristics are high efficiency, excellent reliability, and availability, which are ...
