Field case · Condition monitoring

Condensate pump: thermography found the hot bearing, vibration found the loose bolts, temperature fell from 57 to 36 °C

Quick answer

Thermography showed an overheated non-drive-end bearing in seconds. Vibration analysis then showed 1X with harmonics: looseness. After the bolts were tightened, vibration fell from 2.94 to 0.38 mm/s RMS and temperature from 57 to 36 °C.

What the case covers

Takeaway. A 21 °C drop after tightening bolts is worth about 2.6 times the grease life by the rule of thumb. Fix loose bolts the day you find them.
