Abstract

Abstract:

The fundamental equation of vapor pump and the functional relationship between, parameters are derived at stable operating condition in this paper.The performance of pump regulated by the vapor core during the variation of rotational speed, pressure, mass flow and loading factor is also analysed.A characteristic parameter P2/n2D22,which determines the relative diameter of vapour core is proposed.Additionally,the maximum operating condition and the range of maximum flow are discussed.

Key words: pump, vapour core pump, characterist ic
