Solution To Corrosion/Nigh NSS Problem At Petrotrin Refinery
(Texas A&M University. Turbomachinery Laboratories, 2004)
Determining The Cause Of Bearing Failures In Circulating Water Pump Motors
(Texas A&M University. Turbomachinery Laboratories, 2004)
Eight vertical circulating water pumps are used to circulate condenser water at the generation station in a nuclear power plant. The pump installation is pictured in Figure 1. The motor pump system is arranged vertically ...
Overview Of API 682, Second Edition
(Texas A&M University. Turbomachinery Laboratories, 2003)
APIs recent release of Standard 682, Second Edition, represents a major revision to this standard. The latest revision has greatly expanded the scope of the standard by including applications to more pumps, adding new seal ...
Selecting Steam Turbines For Pump Drives
(Texas A&M University. Turbomachinery Laboratories, 2003)
Selecting the right steam turbine for the application can save the purchaser money on initial cost (avoiding oversizing) as well as operating costs (better efficiency). The intent of this paper is to provide steam turbine ...
Understanding The Performance Of A Progressive Cavity Pump With Metallic Stator
(Texas A&M University. Turbomachinery Laboratories, 2003)
Analytical and experimental studies were carried out on a progressive cavity pump (PCP) fitted with a metallic stator with a fixed, positive clearance around the single helical rotor. This eliminates wear and greatly ...
Developments In High Performance Seal Designs For Critical High Pressure Offshore And Pipeline Applications
(Texas A&M University. Turbomachinery Laboratories, 2003)
Ever demanding business and operating conditions have highlighted the need for significant improvements in the reliability of high duty mechanical seals. With platform operators under pressure to minimize deferred oil ...
Advances In Mechanical Sealing - An Introduction To API 682 Second Edition
(Texas A&M University. Turbomachinery Laboratories, 2002)
The first edition of API 682 was the first broad-based standard covering the design and application of mechanical seals in centrifugal and rotary pumps. One of the main goals of this standard was to capture successful field ...
Design Consideration For A Large Mixer Used In An Agitated Column Application
(Texas A&M University. Turbomachinery Laboratories, 2003)
Industrial agitator or mixer configurations and associated applications present the design engineer with a unique set of challenges. This was especially true when a major chemical company required an agitator for a large ...
Numerical Simulation Of BPF Pressure Pulsation Field In Centrifugal Pumps
(Texas A&M University. Turbomachinery Laboratories, 2002)
There is a close link between the pressure pulsation in the pump working cavity and its vibration and noise level. Due to a current trend in increasing rotation speed and power, the problem of noise, vibration, and pressure ...
Practical Use Of Rotordynamic Analysis To Correct A Vertical Long Shaft Pump's Whirl Problem
(Texas A&M University. Turbomachinery Laboratories, 2002)
The use of long shaft vertical pumps is common practice in the nuclear waste processing industry. Unfortunately, when such pumps employ plain cylindrical journal bearings, they tend to suffer from rotordynamic instability ...
