热合机的定期保养一般由仪管员配合工程技术人员完成，它是一项不断循环进行的有组织有计划的维修措施，这有利于掌握仪器的运行规律，有利于出现故障后的查找：定期保养的内容和时间，不同仪器有不同的做法．一般可以一个月至一个季度进行一次.主要内容除厂日常维护的工作外，可以拆开机壳，清除各处积尘，污垢、异物、紧固螺丝、添加润滑剂；检查务器件、元件有无磨损、变形、烧蚀、击穿、松动，受潮，老化、接地不良等情况；检测各组电源电压及纹波，检查高压部件运行和接触情况等；
The regular maintenance of the heat sealing machine is generally completed by the instrument controller in cooperation with the engineering and technical personnel. It is an organized and planned maintenance measure that is carried out continuously and circularly, which is conducive to mastering the operation law of the instrument and finding out after the failure. The contents and time of the regular maintenance are different for different instruments. It can be carried out once a month to a quarter. Main contents In addition to the daily maintenance work of the plant, the casing can be disassembled to remove dust, dirt, foreign matters, tighten screws and add lubricant; check whether the service components and elements are worn, deformed, ablated, broken, loose, damped, aged and poorly grounded; check the power supply voltage and ripple of each group, and check the operation and contact of high-voltage components;
