breaking of vacuum

Abstract : in this paper , via analysis and research on the actual working situation of jk3 - type vacuum concentrating equipment we have found that reasons of the reduced function of working are the result of that the vacuum degree of work cuts down and isn ' t suitable with the temperature of heating and the heat cycle in each evaporator
文摘:本文通过对jk3型真空浓缩设备工作性能的研究分析表明：导致其生产能力和蒸发量减少，能耗增加，蒸发温度升高，产品质量下降的主要原因是各效蒸发器工作真空度下降，加热温度和热循环与其不相匹配所致。
