摘要:

介绍了大流量三叶罗茨风机的容积效率、机械效率、理想罗茨的绝热效率和全绝热效率ηad,对风机的无逆流冷却和有逆流冷却的两种温度变化情况进行了比较分析.结合生产实例说明,罗茨风机容积效率随径距比的变化,罗茨风机理想罗茨的绝热效率、全绝热效率ηad随风机的压力ε比增加呈现的下降趋势,排气温度随压力比ε增加呈现的上升趋势规律.大流量三叶罗茨风机采用逆流冷却极大地降低排气温度、减小回流冲击噪声.

Abstract:

The volumetric efficiency, mechanical efficiency, thermal insulation efficiency and full adiabatic efficiency ηad of high-flow three-lobe roots fan are introduced, and the temperature changes of non-counterflow cooling and counter-flow cooling of the fan are comparatively analyzed. Combined with production examples, the volume efficiency of roots fan changes with the diameter ratio, the thermal adiabatic efficiency of roots fan, the full adiabatic efficiency ηad with the increase of pressure-to-ε ratio of the fan, and the upward trend of exhaust temperature with the increase of pressure ratio ε. The large-flow three-blade roots fan adopts counter-flow cooling to greatly reduce the exhaust temperature and reduce the return impact noise.
