Research On Equipment Maintenance Model Of Municipal Wastewater Treatment Plant Based On RCM / TPM

In order to improve the efficiency of the sewage treatment plant equipment, this study analyzed the maintenance management mode and the realization method for the wastewater treatment plant equipment.This research mainly uses the methods of literature research, system analysis and case analysis:First of all, the status of equipment management in the wastewater treatment plant is analyzed, the problems and needs of the equipment management are identified, and the corresponding solutions are found by combining the existing equipment management theory.Second, compared with the characteristics of different maintenance theory, the research shows that the single maintenance mode has not adapted to the efficient management of the existing equipment of the sewage treatment plant, and it needs a combination of various maintenance modes. Combining reliability centered maintenance(RCM) method and the characteristics of total production maintenance(TPM) management, this study proposed the combination of RCM method and TPM management. At the same time, the application of the method of fault risk analysis is analyzed, and the application process is established.Third, the sewage treatment plant to focus on process equipment, aeration devices and sludge dewatering equipment, as an independent system for maintenance decision research, developed the method and flow of RCM maintenance decision-making, and carries on the revision to the maintenance cycle with TPM equipment state inspection, make maintenance plan is more practical. Through the practical application of the sewage plant, the efficiency of the maintenance process is improved, and the utilization rate of equipment is improved by 3%. The maintenance mode and the effectiveness of the decision method are proved by the combination of RCM method and TPM management. The results can be used in the maintenance and management of other equipments in the plant.Research shows that the combination of RCM method and TPM management mode and decision-making method for improving the maintenance management of the sewage plant has obvious effect, which is of reference for the similar sewage treatment plant.
