Evaluation Of A High Speed, Light Load Phenomenon In Tilting-Pad Thrust Bearings.
(Texas A&M University. Turbomachinery Laboratories, 2000)
This paper discusses a newly found high speed, light load hydrodynamic tilting-pad thrust bearing phenomenon was first witnessed on centrifugal compressors operating above 10,000 rpm. Testing results have shown that in ...
A Review Of Aerodynamically Induced Forces Acting On Centrifugal Compressors, And Resulting Vibration Characteristics Of Rotors.
(Texas A&M University. Turbomachinery Laboratories, 2000)
There are several sources of nonsynchronous forced vibration of centrifugal compressor rotors. Many of them are aerodynamic phenomena, created within the gas path of the compressor. Phenomena such as impeller stall, diffuser ...
Application Of Foil Bearings To Helium Turbocompressor.
(Texas A&M University. Turbomachinery Laboratories, 2001)
Hydrodynamic gas-lubricated foil bearings are ideal for machinery that operates at high speed or in extreme-temperature environments. As motors and generators run at higher speeds with more torque capacity, the need for ...
Design, Testing, And Field Experience Of A High-Pressure Natural Gas Reinjection Compressor.
(Texas A&M University. Turbomachinery Laboratories, 2000)
This paper explains the design and testing of a high-pressure centrifugal compressor. It also covers commissioning and field experience. Importance issues for high-pressure compressors are highlighted in the paper in general ...
Design And Experience With A 30,000 HP Magnetic Bearing Supported Motor Driven Turbocompressor For A Speed Range Of 600 To 6300 Rpm.
(Texas A&M University. Turbomachinery Laboratories, 2000)
In the Northern Netherlands, after more than 30 years of production, the pressure of the gigantic Groningen onshore gas field is gradually decreasing, requiring up to 500 MW compression over the next 30 years to fulfil ...
Debottlenecking Hydrogen Reciprocating Compressors And Synchronous Motors.
(Texas A&M University. Turbomachinery Laboratories, 2000)
A Midwest refinery realized significant gains in hydrocracker throughput and to its bottom line by debottlenecking its hydrogen makeup compressors. Maintaining and even improving compressor reliability and operating ...
Sidestream Optimization Through The Use Of Computational Fluid Dynamics And Model Testing.
(Texas A&M University. Turbomachinery Laboratories, 2000)
The development of sidestreams for industrial centrifugal compressors presents many difficult challenges for aerodynamic designers. Most often, past practice dictated the configurations used for new applications. However, ...
Gas Damper Seal Test Results, Theoretical Correlation, And Applications In Design Of High-Pressure Compressors.
(Texas A&M University. Turbomachinery Laboratories, 2000)
The rotordynamic and leaking characteristics of two types of gas damper seals, honeycomb seal and pocket damper seal, were experimentally evaluated on a rotating test rig. The effect of supply pressure, preswirl, and seal ...
Eliminating A Rub-Induced Startup Vibration Problem In An Ethylene Drive Steam Turbine.
(Texas A&M University. Turbomachinery Laboratories, 2001)
A 16 megawatt ethylene drive steam turbine built in 1973 experienced rub related startup vibration problems for many years. The turbine would lock into a rub as it accelerated through the rotor’s first critical speed causing ...
