Focus on: Condition Monitoring Maintenance Matters February/March 2023 www.pwemag.co.uk Plant & Works Engineering | 19 than you think. With a short learning curve, ease of collecting data, and remote monitoring solutions, ultrasound can become another valuable tool to use for your condition monitoring efforts. Lubrication PM’s can also become more effective because ultrasound trends will show which bearings need to be lubricated. Therefore, instead of greasing everything on a time-based lube route, only the points that are currently in the lubrication alarm from ultrasound trends are greased until the decibel level drops back down to the baseline dB. If you’re only using ultrasound as a leak detector, I would encourage you to take a more in depth look into condition monitoring with ultrasound. 01706 835 331 | info@spminstrument.co.uk | www.spminstrument.co.uk Safeguard your machinery – it doesn’t have to be complicated Wireless vibration and temperature monitoring Industry-leading measurement technology Wi-Fi or cellular network communication balls (bearings), an outer race, inner race, ball pass, and cage frequency are calculated. For this particular motor, the speed was 1750rpm and the type and number of bearings was confirmed and the number of bearings was 10. The fault frequency calculated by the spectrum analysis software that was of interest was an inner race fault at 175Hz. This is the same fault harmonic detected on the ultrasound instrument. Another interesting point was the fact that the vibration analysis data was collected two days later, and did confirm an inner race fault on the Pump 4 motor outboard point. Conclusion Implementing ultrasound for condition monitoring applications is easier PUMP 4 MTROB 010 Pump 4 MTR OB from the ultrasound instrument. Notice the distinct 175.8Hz harmonics detected.
