Vertically-Suspended Pumps With Water-Lubricated Rubber Bearings - Experimental Identification Of Dynamic Stiffness Coefficients
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2013)
Design and development of vertically-suspended water pumps requires good understanding of the rotor system characteristics with water-lubricated rubber bearings (WLRB). This paper presents a newly-built experimental device ...
Breaking The Cycle Of Pump Repairs
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2014)
Of the numerous process centrifugal pumps undergoing repair right this very minute, an estimated 90% have failed randomly before. Some have run just fine until the very first repair two or three years after startup, and ...
Factors Affecting Oil Ring And Slinger Lubricant Delivery & Stability
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2014)
The choice of which lubrication strategy to apply for pump bearings has implications for both the short term characteristics exhibited by the bearings and their long term reliability. When lubricating rolling element ...
Drive Shaft Failure Analysis On A Multistage Vertical Turbine Pump In River Water Supply Service In A Nickel And Cobalt Mine In Madagascar - Based On ODS And FEA
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2014)
Co2 Capture And Pumping
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2013)
Vertical Integral Thrust Bearing Upgrade
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2014)
Breaking The Cycle Of Pump Repairs
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2013)
Achieving lowest possible life cycle cost (LCC) and valueoptimized mean-times-between-repairs (MTBRs) are the undisputed goals of thoughtful pump users. Achieving these goals requires concentrating not only on pump hydraulics, ...
Bearing Maintenance Practices To Ensure Maximum Bearing Life
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2013)
Reliability of centrifugal pumps is heavily dependent on bearing reliability. The bearings that support the impeller shaft are complex machine components whose service life is directly affected by: Contamination (both ...
Witness Testing Of API 610 Centrifugal Pumps And API 611 Steam Turbines
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2013)
The tutorial outlines the basic concepts and offers some tips on witness testing of API 610 centrifugal pumps and API 611 steam turbines. The section on API 610 pump testing discusses performance, NPSH and mechanical run ...
Using Finite Element Analysis (Fea) To Estimate Reed Frequency Of Vertical Motors For Pump Applications
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Vertical motor/pump systems that run close to the motor reed frequency may experience significantly high vibration levels, which can damage the motor as well as the entire pump system. These damages can result in costly ...
