A Fresh Look at Containment Seals and Equipment
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
The need for reliable and safe sealing of rotating equipment remains as a primary concern for industry. In situations where single mechanical seals were used the introduction of environmental and safety legislation brought ...
Metallurgical Failure Analysis of Steam Turbine, Compressor, and Hot Gas Expander Components
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
When components fail it is usually unexpected and the root cause is not always known. Downtime from failure can cost a company many thousands of dollars a day depending on the type of equipment. This cost can be magnified ...
Digitalisation in Medium Voltage Variable Speed Drive Systems to increase productivity in O&G applications
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
In this paper we talk about influence of digitalization in process industries and how it can be adapted to Medium Voltage drive systems. Various aspects of digitalization like monitoring, preventive maintenance and using ...
Dry Gas Seal Contamination During Operation and Pressurized Hold Background and Potential Solutions
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This paper will discuss the challenges with contamination of gas seals. The reliability of gas seals is largely dependent on having a continuous supply of clean and dry seal gas. In dynamic mode, gas supply systems take ...
Large Cooling Water Pump Upgrade for Increased Capacity And Reduced Impeller Cavitation
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This case study discusses the hydraulic upgrade of two sets of four (25 percent) large vertical cooling water pumps. To increase the electrical output of subject power station, the cooling water pumps of block 1 and 2 had ...

Recip Pump on Unstable Condensate
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Pump Design Conditions, Sealing/Packing System Design Features, Sealing/Packing System Failures, Pump Improvements, Conclusions and Lessons Learned
Increasing Pump Life In Abrasive Service Through State-Of-The-Art Surface Protection
(Texas A&M University. Turbomachinery Laboratories, 2000)
In hydrocarbon processing and oil and gas industries, many pumps are required to transport fluids containing some level of abrasive solids. If not properly designed and equipped with wear resisting materials, the pump ...
Improving Tribological Performance Of Mechanical Seals By Laser Surface Texturing
(Texas A&M University. Turbomachinery Laboratories, 2000)
Significant improvement in load capacity, wear resistance, friction coefficient, etc., of mechanical seals can be obtained by forming regular microsurface structure in the form of micropores on their surfaces. A feasibility ...
Monitoring Repairs To Your Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
Many centrifugal pumps are doomed to premature failure because the total pump installation was not evaluated or the repair activity coordinated to correct the basic cause of the initial failure. Pump users have a great ...
