Machinery condition monitoring includes periodic and on call testing and analysis of rotating machinery. The techniques include primarily vibration testing and assessment to identify equipment in need of repair or modification based on measured data.
The service is beneficial for a number of reasons including:
Service options depend on the needs of the plant, with typical options including periodic vibration monitoring as well as on-call testing when unusual conditions are identified by plant personnel. Periodic vibration monitoring is generally conducted on a monthly basis. On-call testing is triggered by perception of plant personnel or data from online monitoring equipment that indicates possible issues with rotating machinery.
In addition to inspection and analysis services, Kelm Engineering, LLC can also provide reliability improvement services by using the information gathered during routine or on-call testing to identify proactive improvements and modifications of equipment to extend equipment life or to address operational inadequacies.
Kelm Engineering, LLC is a professional engineering company located in Houston that is staffed by engineers and technicians, with vibration analysis programs that are developed and maintained by registered professional engineers with ISO Category 4 Vibration Consultant certification per ISO 18436 through Vibration Institute.
Kelm Engineering, LLC currently is using Emerson Process Management CSI-2140 data collectors and AMS Suite software. Monitoring will include vibration measurement using magnet or stud mounted accelerometers on bearing housings as appropriate per the machinery details as well as measurements from permanently installed vibration monitoring equipment when available in the plant.
Database details include overall and band alarming, PeakView, and other parameters per machine type. Sensors used include accelerometers, proximity probes (when available), key in values (pressures, etc.), and other sensors in special cases.
All testing activities are detailed in written procedures for clear definition of scope of work and to control the ongoing PSM requirements. Each test or measurement is documented with date/time of testing, equipment description, who conducts the test, description of the testing completed and results of the test. Recommendations include identification of likely faults and recommended corrective actions.
