Study on Preventive Maintenance Strategies of Filling Equipment Based on Reliability-Cantered Maintenance

Abstract

In order to ensure normal operation of enterprise production activities and enhance the competitiveness of enterprise, equipment management and maintenance strategy formulation has always been one of important contents of daily management of enterprise. According to the actual requirement of a Chinese beer production enterprise, preventive maintenance strategy of filling equipment is put forward based on reliability-centred maintenance (RCM). Firstly, on the basis of analyzing RCM theory and equipment maintenance, the general process of failure analysis of beer production equipment is presented. Secondly, the general production process of bottled beer is analyzed, and the composition of major filling equipment is also introduced in the beer production line. With the help of key indicators of equipment reliability, such as mean time between failure (MTBF), mean time to repair restoration (MTTR) and availability Ai, the fault analysis of filling production line is carried out, and the relevant results are calculated. Then, process failure mode and effect analysis (PFMEA) of filling machine is implemented, and fault tree analysis (FTA) of potential failure modes with high risk priority numbers is also completed. Finally, preventive and maintenance strategies of filling equipment are established on the basis of RCM. Through the research in this paper, maintenance costs and unplanned breakdown hours can be significantly reduced.

Improvement proposal to increase performance by applying redesign of stations and work methods together with a preventive maintenance plan in a LPG bottling machine

“…Una de las formas de lograr este objetivo es mejorar el proceso de producción. El proceso de producción debe llevarse a cabo de forma continua para reducir la pérdida de material y de tiempo [28] [29]. Del mismo modo, la gestión de capital humano, recursos materiales y financieros en conjunto son importantes, ya que estos permiten una reducción costos y una mejora en la calidad de los productos.…”

“…Mediante el establecimiento de normas de trabajo se permite lograr el aumento de la productividad y reducir el costo por unidad, logrando aumentar su eficiencia de forma que se pueda producir más productos en menor tiempo. [29] En la tercera fase, se ejecutó el diseño del plan de mantenimiento preventivo para las balanzas envasadoras. En [35] para implementar el plan de mantenimiento se debe realizar el análisis de las funciones de la maquinaria, relacionar a las posibles causas de fallo, clasificar las causas y realizar soluciones para mitigar las causas encontradas.…”

“…Corrective maintenance is a task normally performed to identify, isolate, and resolve faults. Whereas predictive maintenance techniques are generally designed to determine and predict failure conditions (Zeng et al, 2021).…”
