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 ...
Vibration Analysis of Gas Turbine’s Transportation Carrigage and Warranty Issues
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This paper describes the investigation of whether the vibration shock limits were exceeded on the transportation of 2 gas turbines. This investigation was requested due to an improper suspension type of the carriage used ...
Applying Upstream Pumping Sealing Technology for high corrosive fluid – Improve Reliability & Operating Cost
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This is a mechanical seal upgrade case study about applying advanced upstream pumping technology instead ofconventional tandem seal arrangements with external flushing in high corrosive fluid pump seal applications in order ...
Rotor Magnetization in Turboexpander and its Effect on Vibration Readings
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
A magnetized rotating machine behaves like an electrical generator. It often produces localized stray current that usually discharges across small clearance paths imposing damage to machine internals and vibration probes. ...
