Thank you Mr. Wee for your extended comments on this Preventive Maintenance. Members who are interested in his CMMS May reach out to him for more details.
Thank you to Mr. Lee Tiang Hock for the detail discourse on the causes of motor failure.
The key words here are 'detect' and 'prevent'. How do mill engineers keep track of the 150 - 200 motors in their mill? To effectively do this, it is recommended that mills implement and maintain a computerized maintenance management program (CMMS). The CMMS will help engineers plan and schedule the preventive maintenance activities for all the plant and machinery in their mill.
For example for motors, the maintenance schedule can be set for Weekly, Monthly, 3-Monhtly, 6-Monthly and Yearly inspections and condition monitoring. Weekly Inspections can include checks for Vibration, Noise and Temperature. Monthly inspections can include normal running amps and No Load amps testing and recording. 3-Monthly inspections can include testing for free running amps and testing of Overload Relays and Yearly inspection will include Insulation Resistance testing.
In addition to scheduling maintenance, the CMMS will include the following features to help the Maintenance Engineer to keep tab on their plant and machinery in the mill:
1. Machinery Database
2. Maintenance Schedules for all machinery in the Machinery Database
3. Works Order and Job Sheets generation from the schedules
4. Corrective Action Required (CAR) after maintenance check or breakdown.
5. Machinery Breakdown Record
6. Machinery History
Attached is a demo video the CMMS program using Excel.
