High Pressure Sealing Systems For Boiler Circulating Pumps
(Turbomachinery Laboratory, Texas A&M University, 2011)
Boiler circulating pumps are among the most critical and difficult rotating equipment in power plants. The bearings and seals are subject to very high loads with respect to forces and temperatures. Typical operating pressures ...
Hazards Of Reverse Pump Rotation
(Turbomachinery Laboratory, Texas A&M University, 2011)
So What Did We Learn About Pumps During The Past 20 Years?
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2014)
The paper discusses and highlights the most prominent critical pump related challenges and experiences Eskom has been faced with during the past 20 years. The challenges include the following: The effects of Pump System ...
High Speed Arrangement 1 Seals In Water Injection Service
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2013)
As the pressure in older oil wells decrease over time, water injection services are becoming more prevalent on offshore platforms. Water injection is used to maintain the pressure in the wells and displace the oil from the ...
Hydraulic Upgrade Of Hot Water Circulation Pumps In A District Heating System
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2013)
Improving Pump Reliability And Longevity By Running In The Sweet Zone
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2013)
Influence Of Impeller Suction Specific Speed On Vibration Performance
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2013)
The most commonly used hard limitation for pump suction specific speed is 11,000 (US units). This hard limit grew out of the recommendations from a 1982 reliability study by J.L. Hallam (Hallam 1982). Concomitant testing ...
Design Of Pump Casings: Guidelines For A Systematic Evaluation Of Centrifugal Pump Pressure Boundary Failure Modes And Their Mechanisms
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2013)
This document contains recommendations of rigorous pump casing design techniques. A comparison of different design methods is made. The most sophisticated of these is then described in detail. Finally, a list of design ...
Design And Verification Testing Of New Balance Piston For High Boost Multiphase Pumps
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2013)
In 2011, the first Subsea Multiphase Pump (MPP) able to deliver a differential pressure of 2175 psi (150 bar) was introduced to the market. This major innovation for the subsea industry conquered the 17 year old 725 psi ...
Short Course P2/T2: The Utilization of Computational Fluid Dynamics in Turbomachinery Design and Analysis
(Texas A&M University. Turbomachinery Laboratories, 2012)
