由于蒸汽噴射真空泵的真空度高、工作能力大、設备簡单、操作及維护方便等一系列优点,因此在輕化、制药、石油、冶金等工业及其他許多国民經济部門中的应用日益广泛。作者曾参与将蒸汽噴射真空泵用于鋼水炉外高真空处理的工作,根据在实踐中摸索到的一些体会,把該泵的安装、运行及故障消除方法等介紹于后,以供参考。 Due to the high degree of vacuum of the steam jet vacuum pump, the ability to work, equipment is simple, easy operation and maintenance and a series of advantages, so in the light of, pharmaceutical, petroleum, metallurgy and other industries and other national economic sectors increasingly widely. The author has been involved in the use of steam jet vacuum pump outside the vacuum furnace for high vacuum treatment work, based on some experience found in practice, the pump installation, operation and troubleshooting methods are introduced for reference.
