Next Generation Pump Systems Enable New Opportunities For Asset Management And Economic Optimization (Texas A&M University. Turbomachinery Laboratories, 2002)There is growing interest in cost-effective techniques that can detect the earliest stage of degradation or malfunction and predict machinery failure. New diagnostic and prognostic techniques may be effectively coupled ...

-
(Texas A&M University. Turbomachinery Laboratories, 2007)This Paper describes design, fabrication, installation and operational experience with non-metallic brush seals installed in all four GT Units, GE-made, Frame No 7, model EA, presently operating at Watson Cogeneration ...
-
(Texas A&M University. Turbomachinery Laboratories, 1988)Nondestructive evaluation is becoming increasingly important in determining the quality of materials and fabrications used in the manufacture and maintenance of rotating machinery. NDE has long been used as a tool for ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2015)Measurement of the modal parameters of rotors is of interest to understand the dynamics of rotating systems, validate design models, and assess how operational parameters affect the vibration response. Torsional vibratory ...
-
(Texas A&M University. Turbomachinery Laboratories, 2010)Continuous improvements in the power rating and switching characteristics of power semiconductor devices have enabled the use of power electronics converters in high power variable speed drives (VSDs). These multimegawatt ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)This case study discusses the rerate of a set of vertically-mounted single-stage end-suction centrifugal pumps used for low pressure safety injection (LPSI) in a nuclear power plant. The original LPSI pumps were supplied ...
-
(Texas A&M University. Turbomachinery Laboratories, 2001)There was a time when people worked on radiologically contaminated equipment with a low level of protection, when equipment leakage was considered unavoidable, and when contaminated equipment was disposed of with little ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2015)The increasing demand of higher efficiency and increased equipment compactness is pushing the modern rotordynamic design towards higher and higher bearing peripheral speeds. Due to the increased viscous dissipation, fluid ...
-
(Texas A&M University. Turbomachinery Laboratories, 2001)With the increase in power per unit of volume for modern pumps, driven by manufacturing costs reduction, cavitation becomes more and more the main limiting factor in pump design. The classical one-dimensional design rules ...
-
(Texas A&M University. Turbomachinery Laboratories, 2008)Pump intake is designed to provide adequate water supply to pumps. It is essential to design the pump intake to provide fairly uniform and swirl free flow to pumps. However, it is not always possible due to site constraints. ...
-
(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 ...
-
(Texas A&M University. Turbomachinery Laboratories, 2007)This paper deals with pump as turbine (PAT) as a feasible solution to the energy problems in rural and hilly areas. PAT provides an economical alternative to actual turbines especially for pico and microhydropower generation. ...

-
(Texas A&M University. Turbomachinery Laboratories, 1997)Oil lubrication systems, when required and provided for the pumping system, are the life insurance policy for the process. If the oil lubrication system should fail to perform, the results are bearing failures in pumps, ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1994)Oil Mist lubrication has been shown to be a very effective method for reducing maintenance costs by minimizing lubrication related bearing failures. What oil mist is, how it works, and typical results from its application ...
-
(Texas A&M University. Turbomachinery Laboratories, 1986)Oil seals are used in many industrial compressor designs where positive control of the process gas is essential. Consideration of the influence of these seals is necessary for proper design evaluation. The oil seals can ...
-
(Texas A&M University. Gas Turbine Laboratories, 1972)The speaker will briefly review the type of problems which have been experienced with lubrication and seal oil systems and their impact upon process compressor train reliability. Recommendations for reducing these problems ...
-
(Texas A&M University. Turbomachinery Laboratories, 2004)Industrial gas turbines allow operation with a wide variety of gaseous and liquid fuels. To determine the suitability for operation with a gas fuel system, various physical parameters of the proposed fuel need to be ...
