Temperature and vibration measurement for fans and pumps
Thread Content
I would like to ask everyone: are there any standard requirements regarding fan and pump equipment as well as the motors associated with them, specifying under what circumstances it is necessary to install systems for monitoring bearing temperature and vibration, as well as motor temperature and vibration?
Based on what is known at present, the existing processes do not specify exactly what power level is required; there is no clear boundary
It mainly depends on the nature of equipment use; for example, in the case of flue gas fans, due to the high levels of impurities in the medium, problems related to imbalance in dynamic balance often occur, and it is necessary to detect these issues promptly and replace the fans to address them. Bearings are required for large centrifugal compressors, as well as in those applications where high vibration tolerance is necessary. The establishment of standards and norms is mostly driven by the needs of production processes; it is not always the case that these standards determine the necessity for their creation. There are also methods that involve using a handheld vibration meter for periodic measurements, but it is better to conduct online measurements and use a computer to display the trends for reference.
