At 1ast , basing on the ana1ysis of experimental date and work practice , it puts forward a new type equipment of vapor ejecting pump vacuum system , which is used for tobacco humidity 并基于实验数据的分析和工作实践，提出了烟草回潮用蒸汽喷射泵抽真空系统的新型配置。
The heat pump evaporation had become a feasible measure of energy conservation . however , the variational work situation influenced both the ejector ' s efficiency and the evaporation capability , even the normal production 蒸汽喷射式热泵蒸发为蒸发行业简单易行的节能措施，但工况的变化会影响喷射器的效率，降低蒸发能力，甚至影响蒸发操作的正常进行。
The inner fluid in the steam pump was discussed through theoretical study , the mathematic model on sucking was educed , and the extension of the model was in conformity to the experimental value of steam eject pump in actual practice 摘要主要对蒸汽喷射泵内流体进行理论研究，推导出了蒸汽喷射泵的抽气数学模型，并给出了该模型与实际蒸汽喷射泵实验值的符合范围。
Second1y , this thesis a1so contrasts and conc1udes on a11 kinds of methods designing vapor ejecting pump , and points out that vege1iner method is a simple but practica1 method on designing vapor ejecting pump vacuum system 其次，本文还对蒸汽喷射泵的各种设计方法做了对比归纳和总结，指出维杰利尔方法是设计烟草回潮用蒸汽喷射泵抽真空系统简单但又非常实用的方法。
