降低水蒸汽喷射真空泵能耗的研究

Study on Reducing Expenditure of Energy of Water Vapour Ejector Pumps

水蒸汽喷射真空泵各级压缩比大小的确定是设计水蒸汽喷射泵的关键，它直接影响到泵的工作蒸汽耗量和冷却水耗量。传统设计方法是凭经验确定各级压缩比的大小，缺乏理论依据。本文运用计算机对水蒸汽喷射泵压缩比进行优化计算，其结果可为今后设计节能型水蒸汽喷射泵提供一些理论依据。

Abstract Determining each stage compressibility ratio of water vapour ejector pumps is key of designing it.This indirect effects expenditure of water vapour and cooling water of pumps.Traditional ways determined each stage compressibility ratio of pumps by experience.These were short of theoretic basis.ln this paper.ee calculated each stage optimum compressibilily ratio of water vapour ejector pumps using computer.The result can suppy a few foundation with designing in future economic type water vapour ejecto r pumps
