Winter Vibration Problems on VS6 Booster Pumps and Solutions
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Background: Three multistage canned vertically-suspended pumps are installed at Kerrobert, Canada to transfer crude oil. The pumps are driven by 1000 HP vertical motor at 885 RPM. Problem Statement: The installed pumps ...
Mechanical Seal and Support System Considerations for Negative Temperature Hydrocarbon Services: NGL Processing and Ethylene Production Focus
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
There are many challenging mechanical seal applications throughout industry and perhaps none more so than those with negative operating temperatures, more succinctly, a temperature value lower than zero on respective ...
Highlights of Draft API 610 12th Edition
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
API 610 Eleventh Edition, Centrifugal Pumps for Petroleum, Petrochemical and Natural Gas Industries, has been updated to the Twelfth Edition. The Eleventh Edition was identical to the ISO 13709 Second Edition; however, API ...
API 682 Arrangement 2 Configurations - Considerations for Outer Seal and Support System Design
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
API 682, now in its 4th Edition, has made a concerted effort to accurately define and distinguish between different types of seal configurations available under the designation of ‘Arrangement 2’, including 2CW-CW, 2CW-CS, ...
Solving a Sever Vibration Problem in the Downstream Piping of a Gear Pump
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
A solution was developed for an extreme discharge piping vibration problem on an 80 hp gear pump piping system. Maximum field-measured vibration levels were over 4 ips 0-pk (200 mm/sec pk-pk). Most gear pumps are not ...
Centrifugal Pump Operation, Maintenance, and Reliability
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2017)
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 ...
Rotordynamic Developments For High Speed Multistage Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)
At present, the majority factor limiting the designer’s ability to predict the rotordynamic behavior of multistage centrifugal pumps is the availability of accurate input data for the forces acting on the rotor. Recent ...
