几种新型空调用大孔径离心式喷嘴性能的对比分析

Comparative Analyses of Performance on Some New Centrifugal Air-condition Nozzles with Large-caliber

运用回归分析方法并借助于计算机建立了PX－I型、PY－I型、FD型和仿LUWA型四种新型空调用离心式喷嘴的喷水压力、流量与出口孔径之间以及水滴粒径、流量与出水口孔径之间的定量关系；提供了四种喷嘴的性能曲线；对四种喷嘴在同一工况下的流量、雾化角、分散度、水滴粒径进行了对比分析。

The quantitative relations among water jet pressure, rate of flow and water exit caliber or amongdrop particle diameter, rate of flow and water exit caliber are established, these are about PX-I,PY-I, FD and LUWA-like four--type new centrifugal jet nozzles with a regression analysis andthe computer. The performance curve of four--type jet nozzles is given, and the rate of flow, atomizing angle, disperse degree and drop particle diameter are contrasted and analysed with same operating condition.
