Case Study: Lateral Analysis Fixes a Multi-Stage Diffuser Boiler Feedwater Pump
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
History gets confusing. A lot of emails, vibration reports, and attempted fixes over the years. Customer spent 3 years working closely with OEM, Pump was shipped back to OEM for additional testing. OEM design suggestions ...
Detection of Misalignment from Vibration Data
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
On a boiler feed pump driven by a motor running close to 3600 rpm, a horizontal misalignment issue was suspected by examining orbit plots besides shaft centerline plots. The follow-up inspection did uncover large parallel ...
Excessive Axial Load on Main Oil Line Pump Thrust Bearing, Measurement and Control
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
This case study describes the deployment of an axial load measurement and control solution for centrifugal pumps experiencing high bearing temperatures on the Non-Drive End (NDE). Through the real-time measurement of the ...
Video Based Vibration: A tutorial and case study with a live demonstration and data analysis on real life pump data
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Recent advances in camera technology allows the user to detect subtle motion and amplify that motion to a level visible with the naked eye. Furthermore displacements, phase and frequency of motions can all be determined ...
Development and Field testing of Strain Gauge Based Torque measurement system for Oil Pipeline Pump Application
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
As part of a PRCI (Pipeline Research Council International) project that involved developing a field testing procedure for large oil pipeline pumps, this case study focuses on the development of a system to precisely measure ...
Balance Line Flow Monitoring Diagnoses Pump Problem
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Two stage BB1 style pump. Lean Solutions service in Gas Separation Plant. Operating at 6075 gpm with 1470 ft of head. Running Plan 53C for mechanical seals. Recently rebuilt and new seals installed
Vibration and NPSHr (NPSH₃), improvement of BB1 two stage pump reliability
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
This case study discusses the impeller redesign of 10 8x15 BB1 two stages Amine pump in a Gas Sweeting Plant in Malaysia. The original pump was supplied in 1996 and after some design changes it had an history of recurring ...
Multi-stage pump vibration caused by excessive wear ring clearance, Improper balancing, rotating stall
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Generally, the centrifugal pump vibration caused by mis-alignment, unbalance or bearing failure. But, I have seen two abnormal vibration phenomena in a multi-stage high pressure pump which has 13th stage impeller.First ...
Significant cost savings in Crude oil / Multiphase pump application by using Diamond seal Face material technology
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
In an upstream facility in Venezuela, Single Mechanical Seals in combination with API 682 Piping Plan 32 and 62 have been used in a Multiphase twin-screw pump application successfully over many years. It was clients target ...
How to detect Electrostatic discharge (ESD) using proximity probes on rotating machines
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
In this session, a brief introduction about electrostatic discharge phenomena will be done. Then three historical cases with Electrostatic Discharge (ESD) issue will be analyzed in order to explain how to detect Electrostatic ...
