二手化工設備的壽命在很大程度上決定于維護保養的好壞。維護保養依工作量大小和難易程度分為日常保養、一級保養、二級保養、三級保養等。 二手化工設備維護保養的內容是保持設備清潔、整齊、潤滑良好、安全運行，包括及時緊固松動的緊固件，調整活動部分的間隙等。簡言之，即“清潔、潤滑、緊固、調整、防腐”十字作業法 首先我們要做好設備的防腐工作。這就需要我們工廠人員不僅要從材料以及防腐手段上面著手，也要注意平時的操作的規范性來達到防腐的效果。在平時的工作中，要對工人進行操作培訓，提高工人的安全生產意識和規范操作能力，嚴格的遵守操作要求，不準超壓、超溫、超負荷運行。 另外，我們工廠的保養人員還要要注意日常的維護和修理，對于一些腐蝕性能較差和壓力容器要注重其養護，能夠建立設備的檔案，對于其制備原料、施工環境等做好相應的檢查和記錄，以便在日常的工作中能夠有效的運作，提高二手化工設備的防腐性能。
The service life of used chemical equipment depends to a great extent on the quality of maintenance. Maintenance according to the size of the workload and the degree of difficulty is divided into routine maintenance, first level maintenance, two levels of maintenance, three levels of maintenance. The maintenance of second-hand chemical equipment is to keep the equipment clean, tidy, well lubricated and safe operation, including fastening fasteners in time and adjusting the gap between the moving parts. In short, the "clean, lubrication, fastening, adjusting and anticorrosion" cross operation method, first of all, we should do a good job of equipment corrosion protection. This requires our factory staff not only from the material and anti-corrosion means to start, but also pay attention to the usual operation of the normative to achieve the effect of corrosion. In peacetime work, workers should be trained in operation, improve workers' awareness of safety in production and standard operation ability, strictly comply with the operation requirements, and forbid overpressure, over temperature and overload operation. In addition, our factory maintenance personnel also must pay attention to the daily maintenance and repair, for some poor corrosion resistance and pressure vessel should pay attention to the maintenance, it is best to set up equipment files for the preparation of raw materials, construction environment and make corresponding inspection records, in order to effectively operate in the daily work, to improve the anticorrosion performance of used chemical equipment. .
