多效蒸馏水机由于其热效率高，量大，出水水质好，并配有自动系统，已被广泛应用。现就我院在使用ＬＤ列管式多效蒸馏水机过程中，所出现的积液、出水量低及内毒素检查不合格的问题及解决办法总结如下。１　　积液蒸馏水机在正常工作状态下，各蒸发器间必须保持一定的压差，操 The multi-effect water distiller has been widely used due to its high thermal efficiency, large volume, good effluent quality, and an automatic system. Now in the process of using LD tube multi-effect distilled water machine in our hospital, the problems of effusion, low water yield and unqualified endotoxin inspection and solutions are summarized as follows. 1 The effusion distilled water machine must maintain a certain pressure difference between the evaporators under normal working conditions.
