- 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.
