Application of Reliability Centered Maintenance in a Bulb Manufacturing Unit

Rupinder Singh, Harmesh Kumar, N. S Bhangu


In the present research work, application of Reliability Centered Maintenance (RCM) in a bulb manufacturing unit has been highlighted as a case study. Three lines of bulb assembly were running at a speed of 4250 bulbs/hour. Due to consistent low machine efficiency, there was an urgent requirement for analysis of the maintenance system.

 Last eight months data has been collected and analyzed for calculating the machine efficiency. The results of study suggested that as regards to down time in bulb manufacturing unit is concerned; sealing, mounting, threading machine, pump and stem contributes 27%, 23%, 15%, 10% and 7% respectively. The result of study proposed preventive maintenance plan with recommended actions.
