Experimental Research on the Axial-flow Impeller Aerodynamic Performance of the Axial-flow Fan
摘要
Abstract
According to GB/T 1236-2000 “Industrial fans---performance testing using standardized airways”,the aerody-namic performance tests of five axial-flow impellers about an axial-flow fan have been carried out respectively.By comparing and analyzing the pneumatic performance experimental data of five axial-flow fans,the influence of different blade angle and leave number of single-stage axial-flow impeller on the axial-flow fan aerodynamic performance parameters have been studied.The change situation of total pressure,dynamic pressure,power,efficiency with change of the blade angle and leave number have been obtained.The experimental results indicate that:under the most efficient operating point,firstly,compared to the same blade an-gle and different number of leaves of the first group test series,the most flow volume and smallest power of axial-flow impeller is Z=6.And compared to the same number of leaves and different blade angles of the second group test series,the most flow volume and largest total pressure of axial-flow impeller is Z=6,β=38°,it has the largest power,moderate total pressure efficiency,the best axial-flow impeller combination with blade angle and number of leaves applied in the newly axial-flow fire-fighting fan has been obtained.关键词
