Resolution of Check Valve Failures in Reciprocating Compressors
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Discharge line check valves for reciprocating compressors are subjected to pressure pulsations, varying flow rates, and debris in the gas stream. Consequently, swing check, piston check, and modified plate-style compressor ...
What’s inside the ‘Box’ When Considering API Piping Plan 54?
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
What could typically drive support system selection towards Plan 54?A Plan 54 support system designation may be selected as it has specific advantages over Plan 53A, B, and C. The primary difference is that the circulation ...
Benefits of Physical Modeling in Large Pump Station Design
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
This presentation explores common problems with pumps and pump stations, issues with pump intake hydraulics, HI standards, physical modeling – key considerations and presents the case study of Dallas Elm Fork WTP Pump Station 1.
ROTORDYNAMIC PERFORMANCE OF A FULLY-PARTITIONED DAMPER SEAL: EXPERIMENTAL AND NUMERICAL RESULTS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Balance piston seals restrict leakage at the discharge side of single shaft centrifugal compressors. There are multiple types of annular seals including labyrinth seals, textured surface seals such as honeycomb seals and ...
Dry Gas Seal Material Investigation for Enhanced Slow Roll & Wind-Milling Reliability
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Dry gas seals, while ideally non-contacting, must reliably perform under all operating conditions encountered by a compressor, including those conditions which induce contact such as slow roll, turning gear, ratcheting, ...
Successful 2 planes balancing confirm by rotordynamics calculation
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
This historical case is focus on the vibration behavior of a generator. After a short circuit issue on the grid, the machine train trip. At this time the level of vibration of the generator was acceptable and well below ...
Optimizing compressor packing designs by predicting rod temperatures.
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
The pressure packing is a critical component of every reciprocating compressor. High wear leads to increased process gas leakage rates which can result in a compressor shutdown. Excessive leakage can even cause fugitive ...
METHODS TO EFFECTIVELY EVALUATE MODERN JOURNAL BEARING PERFORMANCE AND ACHIEVE HIGH RELIABILITY
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Centrifugal compressors and steam turbines commonly use hydrodynamic journal bearings. These bearings can be fixed geometry (sleeve) or tilting pad type. Most end users expect bearings to operate trouble free from major ...
Resolving Centrifugal Compressor Aerodynamic-Performance Issues Related to Inlet Flow Distortion
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
A compressor aero-performance issue occurred during in-house Type 2 testing of a centrifugal compressor – the overload limit was close to the expected design capacity. Root cause analyses initially focused on the compressor ...
Excessive Axial Load on Main Oil Line Pump Thrust Bearing, Measurement and Control
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
This case study describes the deployment of an axial load measurement and control solution for centrifugal pumps experiencing high bearing temperatures on the Non-Drive End (NDE). Through the real-time measurement of the ...
