Mechanical Seals
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Mechanical seals are the most common method of sealing industrial centrifugal pumps
and other rotary equipment. Although the basic concepts of a seal is simple,
successfully using seals requires an understanding of the ...
Sealless Pumps
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Types of sealless pumps and application limitations such as HP, pressure, temperature,
solids, etc.
Applications where sealless pumps have been successfully applied, and where they have
failed
Environmental performance ...
Tutorial on Centrifugal Compressor Surge Control
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
For every centrifugal compressor installation, the design of the surge control system is vitally important to prevent damage of the compressor internal components, seals, and bearings. While most surge control systems are ...
Mechanical, Stress and Flow Considerations for Piping Design of Centrifugal Compressors
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This tutorial covers a range of factors that must be considered in the piping design associated with the installation of any new centrifugal compressor system. Multiple factors must be balanced in the piping design to have ...
The Synchronous Rotor Instability Phenomenon—Morton Effect
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This paper gives an overview on the “Morton Effect” and explains how synchronous rotor instability, due to non-uniform heating of bearing journals, can occur in high-speed turbomachinery. The paper was also presented in ...
Additive Manufacturing and Topology Optimization Applied to Impeller to Enhance Mechanical Performance
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
The paper describes the link between additive manufacturing techniques and topological optimization design process.
An overview of Inconel718 printed material characteristics and as printed quality is given
Finally ...
New Challenges and Design for High Mach High Flow Coefficient Impeller for Large Size LNG Plant
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
The new generation of LNG plant are moving toward a larger size, that mean larger compression stations, driven by higher power gas turbine that can arrive and exceed 100 MW. This increase of specific power means also ...
Maximum Efficiency for High Head Process Pumps –Optimizing Side Channel Pumps
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Side channel pumps provide high pressure at relatively low flow rates. This comes along with a quite low specific speed and thus with the known disadvantage of a quite poor maximum efficiency.
This paper describes the ...
Crude Oil Non-Pusher Secondary Seal
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Crude oil pipeline pumps traditionally suffer from seal leakage due to the fretting or wearing of the dynamic O-ring. A new concept secondary seal has been developed to eliminate this fretting occurrence. All major seal ...
Cooling Water Pump Station Optimization Using CFD and Physical Model Test
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
In this paper, a combined study between Computational Fluid Dynamics (CFD) and a model test has been carried on a Cooling Water Pumping Station as part of a new power plant. The aim of this work was to validate a water pit ...
