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 ...
Plunger Pump Station Vibration-Induced Cracks in Piping
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Many plunger pumps are installed without adequate pulsation and vibration considerations at the design stage. Pressure
pulsations from normal pump operating can cause high shaking forces throughout the entire piping system. ...
NPSHR (NPSH3) IMPROVEMENT OF A LOW PRESSURE SAFETY INJECTION PUMP
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This case study discusses the rerate of a set of vertically-mounted singlestage end-suction centrifugal pumps used for low pressure safety injection (LPSI) in a nuclear power plant. The original LPSI pumps were supplied ...
