喷射泵在冷冻脱水装置中的调控分析

Regulation analyses on ejector used in freezing dewater equipment

喷射泵结构简单,无运动部件,对两相区适应性好,将其作为节流部件引入普通压缩式冷冻机中,产生2个蒸发温度,构造出一种新型的冷冻脱水装置,通过对节流阀或喷射泵的调节改变系统工况。整个机组结构紧凑,喷射泵回收了节流膨胀过程损失的功,并增加压缩机吸气压力,提高了循环性能系数。

The structure of ejector is simple and it has no moving parts,it can suit itself to the two-phase region working situation. The compressing freezing equipment can produce two different evaporating temperatures with ejector as a throttle and the system＇s condition may be changed by the adjustment of the valve or ejector. The structure of the whole equipment is closely arranged, the ejector can recover some work lost in the expansion process and raise the suction pressure of compressor, and so it can raise its property performance of the circulation.
