การจัดทำระบบบำรุงรักษาตามแผนสำหรับเครื่องฆ่าเชื้อแรงดันสูง

Abstract

This research aims to create a maintenance planning system for the High Pressure Processing machine, as currently there is only a plan for repairs when it is damaged. The data recording in 2022 exhibits that the 30-liter High Pressure Processing machine (STI-LTP-HPP-30-01) was downtime for 1,544 hours/year. Therefore, the researcher decides to establish a maintenance planning system by applying the concept of Total Productive Maintenance (TPM). According to the data recording, there are three damage causes including the leaking of the intensifier, the damageRelay, and the damage to the pressure vessel seal. After that, the activity of pillar 3 (planned maintenance) of TPM was applied to create a maintenance planning system for the High Pressure Processing machine. The details of the planned maintenance system are as follows. 1) Inspection checking and maintenance which consists of the daily plan, weekly plan, monthly plan, three-month plan, six-month plan, and yearly plan. 2) Inspection and maintenance documents. 3) Standard operation procedure of Inspection checking and maintenance. The results of the trial of the planned maintenance system over a period of 3 months found that there was no breakdown of the High Pressure Processing machine. Moreover, there is the evaluation of this system with great satisfaction. The average score is 4.63 and standard deviation is 0.49
