Using Finite Element Analysis (Fea) To Estimate Reed Frequency Of Vertical Motors For Pump Applications
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Vertical motor/pump systems that run close to the motor reed frequency may experience significantly high vibration levels, which can damage the motor as well as the entire pump system. These damages can result in costly ...
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 ...
Torsional Instability Of Cooling Tower Fan During Induction Motor Startup
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Torsional instability during starting of an induction motor has caused excessive torque oscillation and eventual failure of gearbox pinion teeth of a cooling tower fan train. A torsional instability appeared due to a steep ...
Double Flow Refrigeration Compressor Inlet Piping Design and Analysis
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Objective: • Design an inlet piping system for a double flow centrifugal compressor that effectively utilizes existing site spacing constraints: • Distributes flow to each inlet evenly with minimal pressure loss and without ...
Why Proper Low Pass Filter Settings on Crosshead Vibration Signals are Crucial to Minimize Risk of Missed Detects
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Crosshead guide acceleration measurements have gained mainstream acceptance by operators of API 618 recips and now joins frame velocity as a recommended shutdown parameter in the 5th edition of the API 670 Machinery ...
Development Of Fuel-Flexible Gas Turbine Combustor
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Growing global energy demands are motivating the gas turbine industry to seek fuel-flexible gas turbines capable of burning a wide variety of fuels as a means of increasing energy supply stability and security. These ...
New Control Method For Fixed Speed Compressors With Side Stream
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Problem statement: Operability issues were experienced on flash gas back-to-back compressors with lower molecular weight side stream, driven by fixed speed electric motor: • Failed attempts of start-up/loading • During ...
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, ...
