Torsional Modal Damping of a LCI Driven Geared Moto-Compressor Train: Evaluation, Optimization Criteria and Active Control
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
The torsional modal response of geared compression trains
driven by Variable Speed Drive Systems (VSDS) can be
heavily affected by electro-mechanical interaction phenomena,
both in terms of excitation mechanism and resulting ...
Dynamic Simulation and Testing To Assess Rundown Speed Of A Compressor
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Dynamic simulations are frequently conducted to verify the behavior of compressor stations during transient events. The
most difficult situation to analyze is the event of an emergency shutdown, due to the very fast ...
Development of a Single Mechanical Seal equipped with a High-Pressure Containment Seal for Multiple Fluid Pipeline Pumps
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This paper discusses the critical design aspects, calculations, laboratory verification testing and field experience of a mechanical seal
arrangement for multiple fluid Pipeline Pumps. The seal cartridge consists of a ...
Subsynchronous Vibrations on a Vertical Electrical Motor During Factory Testing – Observed Phenomenon, Interpretation and Resolution
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
During the factory tests of a vertical electric driven de-ballasting pump, casing vibrations were observed on the motor above the contractual limit of 2.8 mm/s, mainly on the motor’s top, Non-Drive End. Supported by fluid ...
Rotordynamics, Design Aspects, Field and Operational Experiences of a Novel, Large Compressor String Supported by Active Magnetic Bearings
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
The giant Groningen onshore gas field in the Northeastern
Netherlands started production in 1963. About 35 years later,
the decreasing reservoir pressure required a first stage of compression
to provide sufficient capacity ...
A New Methodology for Verifying Pressurized Start-Up of Centrifugal Compressors Driven by Direct-On-Line Electric Motor by Leveraging String Test Results and Dynamic Simulation Analysis
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Fixed Speed Electric Motors driving Centrifugal Compressors are designed considering the pressurized start-up as the most critical
condition in terms of the torque requirement. Their capability is checked during the design ...
On the Performance of Tilting Pad Bearings: A Novel Model for Lubricant Mixing at Oil Feed Ports with Improved Estimation of Pads’ Inlet Temperature and Its Validation Against Experimental Data
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Energy efficient operation of fluid film bearings demands savings in delivery flow while also managing to reduce fluid film and
pad temperatures. To achieve this goal, tilting pad journal bearings (TPJBs) implement a variety ...
