Application of synchronous automatic control watet vapour jet pump in deferrizafion of groundwater 同步自控式水气射流泵在地下水除铁中的应用
The work theory of the roto - jet pump is very specific and it has very simple construction and smooth performance curve and cheap maintain 旋喷泵工作原理比较特殊，结构简单，性能曲线稳定，维护方便。
The design of the pick - up tube accords to the research on the roto - jet pump by other people in china and a new type model is designed 集流管的设计参照了目前国内对集流管的研究并提出了一种改进型的集流管模型。
The pick - up tube is one of the most important overflowing parts , and its design result will directly influent the efficiency of the roto - jet pump 集流管是旋喷泵的重要的过流部件，它的设计的好坏直接影响到旋喷泵的效率。
The calculating results of time - averaged efficiency of pullsed liquid jet pump are approximately in agreement with the experimental results in our and foreign countries 脉冲液体射流泵时均效率的计算结果与国内外的试验结果基本一致。
Secondly , after calculating the pipeline water power and system heat power of the scwr system , the thermal economic nature of the jet pump model scwr system was studied 然后在研究了各种热经济学模式之后，选用会计学热经济模式对喷射泵式蒸汽冷凝水回收系统进行了热经济性分析。
The theoretical and experimental results show that the efficiency of transmission of energy and mass to use pulsed jet is greatly raised , compared with steady jet , in the same device of liquid jet pump 结果表明，在相同的液体射流泵装置上，采用脉冲射流比恒定射流的传能及传质效率有较大的提高。
A new type of very low specific speed pump ? roto - jet pump is presented for low flowrate and high head transportation , which is introduced at the end of the thesis 论文最后主要研究了一种隶属于极低比转数离心泵范畴的新型泵? ?旋喷泵，它是一种新型的石油化工用泵，具有流量小、扬程高、流量扬程曲线平缓的特点。
Streaming from the hot end to the cold end of the regenerator was found which would waste much useful heating energy . modified structure of the jet pump could control this sort of streaming efficiently 实验中还观察到了直流现象，气体从回热器热端向冷端运动，造成大量的能量浪费，通过改进喷射泵结构可以有效抑制直流。
