窄缝式增氧喷水嘴的试验研究

Experiment Research on the NarrowSeam Type Injector of the Aerator　(NSIA)

摘要: 为解决寒冷地区专用增氧机利用率低、投资大、难以推广的问题，开发了一种窄缝式增氧喷水嘴，阐述了其工作原理、结构参数。将之安装在渔场普遍使用的ＪＱＢ、ＱＹ系列潜水电泵上，既可达到增氧，又可排灌；且具有结构简单、成本低、效率高、经济效益显著的特点。

Abstract: NSIA can solve the problems i．e． in the cold region the aerators are inefficient,need much money input and are difficult to be extended． The operating principle and structure parameters of NSIA were discussed.NSIA can be installed in JQB or Y series electresubmersible pump for use of aeration and irrigation and drainage. The NSIA possesses of simple structure,low cost and notable economic results.
