Full Scale Validation Of A High Pressure Ratio Centrifugal Compressor
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
The present paper describes the test activities which have validated a new compressor architecture, developed by the OEM, which is able to deliver a higher pressure ratio in a single casing with respect to traditional ...
Squeeze Film Dampers: A Further Experimental Appraisal Of Their Dynamic Forced Performance
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Squeeze Film Dampers (SFDs) are effective means to ameliorate rotor vibration amplitudes and to suppress instabilities in rotor-bearing systems. A SFD is not an off-the-shelf mechanical element but tailored to a particular ...
Compression Packing: A Traditional Sealing Method Achieving High Levels Of Performance With Modern Technology
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
The oldest and still quite common sealing device for pumps is compression packing, so called because of the manner in which it performs the sealing function. This tutorial will explain the technology and also clarify some ...
A CFD Primer: What Do All Those Colors Really Mean?
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
This tutorial provides a general overview of computational fluid dynamics (CFD). It is not intended for CFD experts but rather for those seeking answers to questions such as: What is the role of CFD in the design / analysis ...

Potassium Carbonate Pump Failure : High Axial Movement due to Uncontrolled (unbalanced) forces
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
A multi stage pump 1.4 MW was in operation till 4 years, the pump stand still for mean period without any failure symptoms , all last measurements (casing vibration, pressure ,flow) was OK , when the pump operated again ...
Solving an Acoustic Resonance in Crude Oil Pump Internals
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Specific Problem: Crude oil pump piping system that had previously operated without problems experienced a failure resulting in a release of oil: Vibration increased when a new well was opened and the fluid properties ...
Improved Mechanical Seal Design for High Temperature/Light Slurry Applications
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Extracting hydrocarbon products in oil sand formations requires high pressure to drive fluid out of the formation and to move the products out to production. The pump models that fit this operating envelope are not common ...
Investigation of process gass compressor shaft vibration phenomena
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
This paper presents details of investigation results of issues observed during plant start-up on a centrifugal compressor. Compressor was operated with air/ nitrogen during start-up and high shaft vibration (approx. 75 um) ...
