MSI always considers the machine as part of a system, including components such as the foundation, the piping network, associated valves, the process fluid, and everything associated with the successful operation of the machine. Our comprehensive test and analysis techniques help tell the whole story on what’s wrong, and how to make it right.
While MSI is often called upon to solve challenging vibration problems with rotating machinery, successful diagnosis and resolution often requires evaluation of the complete system, including the piping and pressure vessels. Often, the excess vibration captures the attention of the operators, while the underlying root cause is later found to involve the piping. MSI has the necessary instrumentation and data acquisition expertise to measure pressures and strains in these systems, along with the advanced analytic capabilities to predict these values. Our experience allows us to compare experimental against analytic results to uncover the thorniest issues in industrial systems.
Mechanical Solutions, Inc. (MSI) was contracted by a manufacturer to perform a seismic structural analysis on three identical large pump systems in a low-activity and high-activity nuclear waste treatment process.
A nuclear power plant’s generator stator cooling pumps had experienced random elevated vibrations during steady conditions since their installation in the 1980s.
Staff at a nuclear power plant was trying to understand why their new feed water pumps exhibited high vibration and showed step changes over time with inconsistent alignment behavior.
