摘要
真空操作普遍应用于在化工及制药行业,文章总结了化工真空系统的计算过程,从判断系统的流动状态计算流导,计算真空有效抽速,最后得到实际的真空泵抽速。归纳了影响真空系统的一些操作因素。
Vacuum operating condition is often applied in chemical and pharmaceutical industries. In this article, the calculation used for vacuum system in chemical process was summarized. Based on determining the lfowing status in the system, lfow conduction and efifcient extracting capacity needed were calculated. Then, the actual extracting capacity of vacuum pump was obtained. Some operating factors inlfuencing vacuum system were ifnally concluded.
