在进行聚氯乙烯的生产过程时,聚合釜是其中所不可或缺的一项设备,如果聚合釜的机械密封一旦由于使用年限过期亦或是因为其他相关原因而发生了失效情况,便很有可能会导致企业生产将面临巨大的安全隐患。本文简要介绍了聚合釜机械密封的工作原理及特点,针对机械密封失效的主要原因展开了深入的研究工作,结合本次研究,进一步提出了一些针对性的改进措施,以期能够实现对聚合釜机械密封使用年限的有限延长,确保其日常运行达到良好的稳定性与安全性。
Polymerization vessels are an indispensable element in the production of PVC and if the mechanical seal of the polymerization vessel fails once due to expiration of its service life or for any other relevant reasons May lead to enterprise production will face a huge security risk. In this paper, the working principle and characteristics of the mechanical seal of polymerizer are briefly introduced. In the light of the main reasons for the mechanical seal failure, an in-depth research work is carried out. Combining with this study, some further improvement measures are put forward, Limited extended use of the seal to ensure that its daily operation to achieve good stability and safety.
