-
(Texas A&M University. Turbomachinery Laboratories, 1994)The use of engineering thermoplastics is increasing rapidly in today's turbomachinery industry. The primary use of these thermoplastics has been as a material upgrade from aluminum for centrifugal compressor labyrinths. ...
-
(Texas A&M University. Turbomachinery Laboratories, 1993)The stabilizing effects achieved by replacing labyrinth seals with honeycomb seals are described. Although honeycomb seals have been used for some time in high pressure compressors and other turbomachinery applications, ...
-
(Texas A&M University. Turbomachinery Laboratories, 2005)The inducer is a very small booster pump, lifting the suction pressure to a sufficient level for the main conventional impeller. By adding the inducer to high speed centrifugal pumps, NPSHr can be reduced to a great extent. ...
-
(Texas A&M University. Turbomachinery Laboratories, 2003)The industrial gas industry has been using integrally geared compressors for over 35 years. This industry has the most experience in the design aspects, the commissioning, and the operation of this style compressor. With ...
-
(Texas A&M University. Turbomachinery Laboratories, 1999)Steam turbines are used throughout the process industries and provide a reliable means of driving pumps, compressors; and other rotating equipment. Carbon rings are currently the most common way . of seali g these ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)Use of Operating Deflection Shapes (ODS) has become an accepted method for understanding and diagnosing pump and other turbomachinery vibration problems. However, data acquisition can take a long period of time, and requires ...
-
(Texas A&M University. Turbomachinery Laboratories, 2003)Sealing volatile high-pressure fluids has always been a challenge unless the temperature is cold enough to produce a true liquid state around the seal. Even handling true liquids having low boiling points can result in low ...

-
(Texas A&M University. Turbomachinery Laboratories, 1998)Wavy face technology in mechanical face seals is the use of circumferential waves manufactured into a seal face. This unique wavy shape is bidirectional, can be used in liquids, gases or combination, and incorporates a ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)A description is presented from a user’s viewpoint, of a vibration monitoring program using a portable data terminal (PDT) system. A brief description of these systems is given, followed by an explanation of what they can ...
-
(Texas A&M University. Turbomachinery Laboratories, 1995)As organizations reengineer to become more competitive and as people are exposed to the purchase of new machinery in an increasingly competitive international market, an acquaintance with the activities needed for effective ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)Exxon Chemical like many other petrochemical companies and refineries, is announcing emission plans with a long term goal to achieve continuous emission reduction from the plant sites. Exxon Chemical’s emission plan has ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)Numerous surveys have shown that the shaft seal is the dominate root cause of failure for the chemical process pump. These component failures are attributed with the lion’s share of the pump maintenance cost. Moreover, ...
-
(Texas A&M University. Gas Turbine Laboratories, 1980)Described in this paper is a device referred to as a soundtube, which has been designed to accurately measure only the normal component of the surface velocity of a vibrating structural noise source. Both laboratory and ...
-
(Texas A&M University. Turbomachinery Laboratories, 1995)A new type of labyrinth seal that reduces cross coupled rotor forces and produces a remarkable amount of damping has been invented at Texas A&M University. Laboratory tests have shown complete elimination of critical speeds ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Background - Pump application: This case study is based on an application supplied into a Polysilicon production facility. The purpose of the application is to pump Trichlorosilane (TCS) liquid into the production process ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)The great value of using multidisciplinary task groups to conduct root cause failure analyses (RCFA) on pump and rotating equipment failures is discussed. The RCFA method offers its users a structured means of achieving ...
-
Using Fiber-Optic Pressure Sensors To Detect Cavitation And Flow Instabilities In Centrifugal Pumps (Texas A&M University. Turbomachinery Laboratories, 1998)This paper introduces the benefits of applying the fiber-optic Fabry-Perot interferometer (ffpi) pressure sensor as a means of detecting cavitation and flow instabilities in centrifugal pumps. The need for monitoring dynamic ...
-
(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 ...
-
(Texas A&M University. Gas Turbine Laboratories, 1978)Acoustic emission is the release of high frequency sound energy in a material under strain. It is the result of microscopic changes in material structure and is associated with deformation and defect growth. Until about ...
