摘要: 本文扼要地阐述了水蒸汽喷射真空泵现场调试的几个关键问题,如:蒸汽管网中凝结水的排除;蒸汽的节流减压减湿以及冷凝器供排水系统的水力计算方法。本文还提出一种用正压法代替真空法用于真空系统检漏的等效方法。

Abstract: This paper concisely explains the key points in the commissioring of steam jet vacuum pumps on job sites, Such as: discharging of condensate in steam lines, reduction, of the pressure and the humidity by pressure regulating valves and the calculation method of hydraulics in water transporting pipes for condensers. This paper relates to a method of equivalence for inspection of leakage in vacuum system by applying the method for building-up of positive pressure instead of the method for building-up of vacuum.
