Did you miss Gary’s discussion of pump hydraulics earlier this year? You’re in luck! We are rerunning this popular topic in a partnership with Pumps & Systems magazine.
Join instructor Dr. Gary Dyson as he discusses how fluid movement has consequences for pump reliability.
Hydro’s condition monitoring solution, Centaur, is currently being used to monitor rotating machinery at a Gulf Coast terminal facility. Through Hydro’s Centaur system, real-time vibration amplitude levels and temperature levels are collected and stored at several measurement locations on compressors and their drive trains. Analysts at Hydro’s Monitoring and Diagnostic Center help to evaluate the collected data. They use their subject matter expertise to make recommendations to the end user when they identify actions that could minimize downtime and maximize the lifespan of the monitored machinery.

A Midwest power utility customer was experiencing increased vibration after a refurbished Condensate pump was reinstalled on-site. They reached out to Hydro Reliability Services to help troubleshoot the vibration issue and determine if it was a problem inherent to the equipment or the result of the refurbishment.

A major power plant in the United States experienced high vibration and recirculation issues with several ring section (BB4) boiler feed pumps, resulting in multiple catastrophic failures and unplanned outages. This case study details one of the pumps that was shipped to an aftermarket pump service center for a full analysis, troubleshooting, repair plan, rebuild and performance testing.
In combined-cycle plants, the demand for robust, yet expensive, barrel pumps diminished as the industry moved toward less expensive segmental rings pumps. Due to the recent shifts in the power industry, operators often face a shorter mean time between repair (MTBR), internal wear and high vibration issues on newly installed units.
After experiencing numerous boiler feed pump performance and reliability issues at their power plant, the plant owner opted to pursue a comprehensive root cause analysis and repair plan with an aftermarket pump service center in Los Angeles, California. The investigation ultimately revealed a series of underlying issues linked to the performance problems and unexpected pump failures.
