Field Testing & Troubleshooting

MSI specializes in field testing and vibration troubleshooting of critical service rotating machinery for all industries including energy, oil & gas, water & wastewater, transportation, and others.  Typical equipment includes pumps, compressors, turbines, fans, bearings, gearboxes, motors, generators, and more.  A vibration troubleshooting effort may include experimental modal analysis (EMA) to determine system natural frequencies, operating deflection shape (ODS) characterization to observe system behavior under operational loading, and continuous monitoring during transient events using ME’scope.  By evaluating the entire system, including foundation, support structures, piping, etc., and employing supplementary tools such as finite element analysis (FEA) and computational fluid dynamics (CFD), MSI is able to solve the most challenging problems when others have failed.  Explore our case studies or contact an engineer to discuss your challenge.

Featured Case Study


Pipe Strain Causing Pump Vibration

Mechanical Solutions, Inc. (MSI) was contracted by a coal power electricity generation plant to perform thorough and specialized vibration testing of the main turbine driven boiler feed pump (TDBFP). It was previously reported that for several years, high shaft vibration had been detected at the pump inboard bearing (IBB), but mostly in the X direction.

Root Cause Analysis of Pump Rotor Failures

Impact testing was used to determine the reasons for three failures of a hydrocarbon cracking pump which was critical to a diesel fuel production process at a major California refinery. Each failure closed down or severely curtailed fuel production at the refinery, at an average cost of about $3/4 million per day.

Curing Resonance in Reactor Feed Pumps

A newly constructed European nuclear power plant had all of its main feed pumps exhibiting vibration on the bearing housings in excess of the vibration specifications, by up to a factor of three, depending upon operating load. Nearly all of the vibration was at vane passing frequency.
