Screw compressor
Thread Content
Is it feasible to install a temperature sensor at the screw air compressor head to monitor the temperature of the bearing in that head? Is it needed? I feel that the temperature of the lubricating oil in the air compressor itself can reflect the operating temperature of the bearings.
Everything that’s needed is already there; just make good use of it. Once there is an abnormality in the bearing, a bearing temperature detection element should be available.
The screw compressor has only an over-temperature alarm, but the temperature being measured is the oil temperature, specifically the temperature of the oil inside the oil-gas separator; it is this temperature that triggers the over-temperature alarm, not the temperature inside the compressor head. There is a slight difference between the two temperatures.
In some of these compressors, the temperature sensor is located on the bearing housing; if it isn’t there, simply drill a hole, tap it, and insert one. I just don’t know what it looks like, or whether it exists in that location at that depth.
The screw compressor is equipped with an exhaust temperature probe and an oil temperature sensor; it will issue alerts in case of any problems, so there’s no need to worry too much
