A Review Of NSS Limitations: New Opportunities
(Texas A&M University. Turbomachinery Laboratories, 2009)
Specifications of some pump users limit the suction specific speed (Nss) with the objective of selecting more reliable centrifugal pumps. This limitation is based on a statistical evaluation of pump failures published by ...
Validation Of Numerical Procedure For Assessment Of Centrifugal Pump Cavitation Erosion
(Texas A&M University. Turbomachinery Laboratories, 2009)
This paper presents validation of a novel method for assessment of the centrifugal pump cavitation erosion with two configurations of a model feed centrifugal pump: with thru shaft, and Cantilever impeller. The method ...
A Vision For Pump R&D Over The Next 25 Years
(Texas A&M University. Turbomachinery Laboratories, 2009)
Energizing research and development on pumps in today’s emerging global and environmental context is envisioned as a major feature of the pump industry in the next quarter century. The mission for how to realize this vision ...
Hybrid Pump: A New Type Of Pump For The Pazflor Deep Sea Project
(Texas A&M University. Turbomachinery Laboratories, 2009)
Subsea processing gives pump engineers permanent technical challenges due to the comprehensive specifications that often stretch the proven limits of technology. It is particularly true for pumps that have to boost a ...
Power Pump Valve Dynamics
(Texas A&M University. Turbomachinery Laboratories, 2009)
The dynamics (movement) of the check valves in a reciprocating power pump determine whether the pump will operate quietly and smoothly, or noisily with pulsation and vibration. Although piping pulsation and vibration are, ...
Dynamic Improvement Of An Overhung Single-Stage Pump
(Texas A&M University. Turbomachinery Laboratories, 2009)
Vibration control is an important aspect of all pump design. It helps assure quiet operation and high reliability. Therefore, the design of pump components should avoid any dangerous resonances with excitation forces, such ...
Contemporary Guide To Mechanical Seal Leakage
(Texas A&M University. Turbomachinery Laboratories, 2009)
The mechanical seal is a critical component in many mature industrial processes such as flue gas desulphurization, crude oil transport and refining, electricity production, and pharmaceutical manufacturing. A “critical ...
