Abnormal temperature fluctuations at point B of the compressor secondary bearing
Thread Content
There are abnormal fluctuations in the temperature at point B of the compressor’s secondary bearing; however, there are no changes in flow rate, inlet and outlet pressures, or gas volume. Please analyze the possible causes.
Such reasons are quite complex; if it is possible to break them down for inspection, that would be the best approach. Tile-type bearings should belong to the category of sliding bearings. In such bearings, an increase in temperature is not necessarily indicated when they are damaged; however, apart from issues related to the measuring instruments, any rise in temperature is likely due to damage to the bearing itself. When such problems occur, first check whether the sound is normal. What are the trends in temperature and vibration for the other bearings, including checking whether there are any abnormalities by touching them with hands or using a stethoscope to listen to them. These tasks are judged based on the insights accumulated from routine inspections of this kind. Regarding the instruments, first cut off the interconnection at this point, check the wiring terminals, or try replacing the temperature sensor; if there are indeed no issues, it’s time to shut down the equipment for a thorough inspection. It is recommended to specify the type and model of the compressor, as well as its flow rate, pressure, or power, to facilitate discussion. For reference.
This requires close monitoring to ensure that the instrumentation is functioning properly
