摘　　要：介绍了水喷射式真空发生器的结构和原理,提出了在纸机干燥部利用水喷射式真空发生器替代传统真空泵产生真空的方式,解决了传统真空泵运行过程中由于蒸汽进入而导致的汽蚀问题,改善了纸机低温段的排水。The structure and principle of water jet vacuum generator was introduced,and using water jet vacuum generator instead of the traditional vacuum pump to generate vacuum in the paper machine drying section was put forward,which can solve the cavitation problem caused by steam entering in the operation of the traditional vacuum pump and improve the drainage in the warm up section.
