The Effects Of Pulsations On The Surge Margin Of Centrifugal Compressors In Stations With Both Reciprocating And Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 2009)
Mixed operation with both centrifugal and reciprocating compressors in a compression plant poses significant operational challenges as pressure pulsations and machine mismatches lead to centrifugal compressors’ instabilities ...
Rotordynamic Stability Of A 9500 Psi Reinjection Centrifugal Compressor Equipped With A Hole Pattern Seal-Measurement Versus Prediction Taking Into Account The Operational Boundary Conditions.
(Texas A&M University. Turbomachinery Laboratories, 2009)
Extensive stability measurements were performed during the full-load, full-pressure factory testing of a five-stage inline centrifugal compressor. The compressor, tested up to a maximum discharge pressure of 655 bar (9,500 ...
Steam Turbine Pipe Strain Case Study
(Texas A&M University. Turbomachinery Laboratories, 2008)
This is a case study of a new steam turbine installation in which pipe strain became an issue after commissioning and start-up. This case study will bring light to the use of shaft indicator movement vs. turbine casing ...
Torsional Instability Of Cooling Tower Fan During Induction Motor Startup
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Torsional instability during starting of an induction motor has caused excessive torque oscillation and eventual failure of gearbox pinion teeth of a cooling tower fan train. A torsional instability appeared due to a steep ...
Double Flow Refrigeration Compressor Inlet Piping Design and Analysis
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Objective: • Design an inlet piping system for a double flow centrifugal compressor that effectively utilizes existing site spacing constraints: • Distributes flow to each inlet evenly with minimal pressure loss and without ...
Why Proper Low Pass Filter Settings on Crosshead Vibration Signals are Crucial to Minimize Risk of Missed Detects
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Crosshead guide acceleration measurements have gained mainstream acceptance by operators of API 618 recips and now joins frame velocity as a recommended shutdown parameter in the 5th edition of the API 670 Machinery ...
Development Of Fuel-Flexible Gas Turbine Combustor
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Growing global energy demands are motivating the gas turbine industry to seek fuel-flexible gas turbines capable of burning a wide variety of fuels as a means of increasing energy supply stability and security. These ...
New Control Method For Fixed Speed Compressors With Side Stream
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Problem statement: Operability issues were experienced on flash gas back-to-back compressors with lower molecular weight side stream, driven by fixed speed electric motor: • Failed attempts of start-up/loading • During ...
Radar-Based Sensors - A New Technology For Real-Time, Direct Temperature Monitoring Of Crank And Crosshead Bearings Of Diesels And Hazardous Media Reciprocating Compressors.
(Texas A&M University. Turbomachinery Laboratories, 2006)
Surveys aiming to isolate the main causes of severe damage of large machines such as reciprocating compressors and diesel engines clearly indicate the need for a reliable method to perform real-time monitoring of the ...
An Impeller Dynamic Risk Assessment Toolkit.
(Texas A&M University. Turbomachinery Laboratories, 2006)
A standardized and cost-effective risk assessment toolkit is described in this paper to comprehensively analyze centrifugal compressor impellers under steady and dynamic loads. The first step in this process occurs in the ...
