Note: This root cause analysis (RCA) is from real-time scenarios that happened in industries during the tenure of two or three decades ago. These articles will help you to improve your troubleshooting skills and knowledge.
Why low on stream hrs? Because of the V-belts coupling the 1500 RPM motor and 750 RPM pulverizer last max a month!
Why? The reasons are:
A few days ponder showed a way out: the author recalled his college day pole changing motor topic; though he did not understand Motors application Handbook” given winding change details, and electrical engineers were diffident, a smart re-winder rewound a test motor for 750 RKM.
Its tire coupling coupled to a pulverizer did so well that all enthusiastically modified all the pulverizers’ drives within a month.
The below are the mentioned benefits of the author’s solution.
