通过理论计算分析蜗壳宽度变化对风机效率和声功率级的影响,拟合一优化函数使其同时考虑到蜗壳宽度对风机效率和声功率级的影响.以 T4-72型通风机为研究对象,计算其各函数关系式,并采用 MATLAB 软件将各函数关系式生成曲线,通过分析曲线确定出离心风机的最佳蜗壳宽度.通过上述方法得出结论:对于T4-72型通风机,当蜗壳出口宽度 C 为蜗壳终了截面张开度 A的1.3倍时,最佳蜗壳宽度约为0.481m,此时的风机效率最高,且声功率级最低.

@@@@Based on theoretically calculating and analyzing the effect of volute width variation on the fan efficiency and acoustic power level, fitting and optimization function is carried out to determine the effect of volute width on fan efficiency and acoustic power level. Take T4-72 type fan as the research object, each function equation is calculated and the function equation curve is generated based on MATLAB software, and the optimal volute width is determinded through the analysis of curve. Through the above methods, for T4-72 type fan,when outlet width of volute C is 1.3 times end section opening A of spiral case, the optimal width is about 0.481m , at the same time the fan efficiency is the highest, and sound power level is the lowest.
