Impact Of Electrical Noise On The Torsional Response Of VFD Compressor Trains
(Texas A&M University. Turbomachinery Laboratories, 2012)
The popularity of VFD motors in compressor trains has increased in recent years. Increased process flexibility is a primary consideration for implementation of VFD systems. However, this comes at a cost of increased ...
Shop Rotordynamic Testing - Options, Objectives, Benefits and Practices
(Texas A&M University. Turbomachinery Laboratories, 2013)
Understanding the lateral rotordynamic behavior is critical in determining the reliability/operability of rotating equipment. Whether examining a centrifugal pump or compressor, steam or gas turbine, motor or generator, ...
Rotordynamic Design Of Centrifugal Compressors In Accordance With The New APIStability Specifications.
(Texas A&M University. Turbomachinery Laboratories, 2005)
The American Petroleum Institute (API) has recently implemented new rotordynamic stability specifications for centrifugal compressors. The specifications consist of a Level I analysis that approximates the destabilizing ...
Lateral Rotordynamics of Petrochemical Equipment - Review, Examples and Problems
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Preventing Undetected Train Torsional Oscillations
(Texas A&M University. Turbomachinery Laboratories, 2010)
In the past few years the authors have encountered numerous problems and coupling failures related to unexpected torque fluctuations on applications with reciprocating compressors and on VFD, synchronous motor, and gas ...
Short Course T7: Lateral Rotordynamics of Petrochemical Equipment - Review, Examples, and Problems
(Texas A&M University. Turbomachinery Laboratories, 2014)
This course is aimed at machinery and project engineers and technicians who need a basic understanding of critical speeds, response to unbalance, and stability of rotating machinery. The course is intended for the layman’s ...
Short Course T4 On Lateral Rotordynamics of Petrochemical Equipment - Review, Examples, and Problem
(Texas A&M University. Turbomachinery Laboratories, 2011)
Knowledge-Based Tool Development And Design For Reciprocating Compressors.
(Texas A&M University. Turbomachinery Laboratories, 2009)
Condition monitoring data collection capabilities have grown over the last decade in large part due to advances in integrated circuits (IC). These advances now permit real time thermodynamic and process calculations on ...
Retrofit Of Gas Lubricated Face Seals In A Centrifugal Compressor.
(Texas A&M University. Turbomachinery Laboratories, 1987)
There are significant advantages in using gas lubricated face seals (dry gas seals) in centrifugal compressor service. Foremost among these are the elimination of the seal oil system resulting in lower maintenance, increased ...
Subsynchronous Vibration Problem And Solution In Multistage Centrifugal Compressor.
(Texas A&M University. Turbomachinery Laboratories, 1987)
The investigation of a subsynchronous vibration problem encountered in a six stage centrifugal compressor is discussed. At a running speed of approximately 9000 rpm, a subsynchronous vibration (at 4200 rpm) of nearly two ...
