Investigating the Influence of Reliability Centered Maintenance on Water Treatment Plant Pumps (Case Study: Guilan Water Treatment Plant)

Abstract

With the increase in maintenance and repair costs, as well as changing expectations towards the growth of efficiency and increasing the life cycle of equipment, detecting the possibility of failures before they occur and reducing the time of breakdowns and stops, maintenance and repairs and condition monitoring of equipment have become more important. Reliability-centered maintenance is one of the methods and strategies that are systematically related to equipment maintenance and repairs. Since the pumps are the center and axis of the treatment plants, their study can be of great significance. This is because the output of the water and sewage industry is very important because of its connection with people's lives. The current research is focused on investigating the impact of RCM strategy on water treatment plant pumps by using the Analytical Hierarchy Process. Questionnaires were designed based on objectives and criteria, and the weighting of data was done by the AHP method. Also, information worksheets and RCM decision worksheets for pumps were designed and completed. In total, the MTBF index of clear water pumps was investigated in two time periods (from June 2021 to June 2022 and June 2022 to June 2023). The data analysis shows that the value of this index increased in the second period compared to the first period, which indicates the positive effect of Reliability Centered Maintenance activities.
