<p>Maintenance management function is enhanced during an actual operation by making it possible to accurately measure temperature at the bearing portion of a refueling screw compressor as well as making it possible to pick up a temperature detection signal from a temperature sensor to the outside of the casing, and facilitating the fixing and removing of the temperature detection end, thereby making it possible to manage temperature at the bearing part. In the refueling screw compressor (1) comprising a radial bearing (5) and a thrust bearing (6) for supporting the rotating rotor shafts (2a or 3a), the radial bearing (5) and the thrust bearing (6) are so worked as to be provided with bottomed hole spaces (25, 34) into which to insert the temperature detection end (26), and through holes (28, 35) for allowing communication between a radial bearing insertion space (s1) formed inside the casing wall (1c) for encasing the radial bearing (5) and the outside and for guiding a sheath pipe (27) integral with the temperature detection end (26) from the outside are bored in the casing wall. The temperature detection end (26) is inserted into the bottomed hole spaces (25, 34) from the outside of the casing wall (1c) through the through holes (28, 35) and the radial bearing insertion space (s1) and fixed in place.</p> |
