What is Crankcase Explosion and reasons/causes of its occurance? What actions you will take if oil mist has occurred?

1. Avoid “hot spots”
2. Detect the oil mist In time.

• “Hot Spots’ in Crankcase

Well-maintained bearings only overheat if the oil supply fails, or if the bearing journal surfaces become too rough (owing to the lubricating oil becoming corrosive, or being polluted by abrasive particles).

For these reasons, it is very important to:

• – purify the lubricating oil correctly,
• – make frequent control analyses
• – ensure that the filter gauze is maintained intact.

Due to the high frictional speed of the thrust bearing, special care has been taken to ensure the oil supply to this bearing.

Monitoring equipment is arranged to give an alarm in cases of low circulating oil pressure and/or high temperature of thrust bearing segments. Keep this equipment in tiptop condition.

Feel over moving parts (by hand or with a “thermo-feel”) at suitable intervals (15-30 minutes after starting, one hour later, and again at full load.

lf in doubt, stop and feel over.
