G、Y6-41系列通風機所用的設(shè)計方法:選擇合適的風機型式,合理的風機工況,優(yōu)選流型,合理組織氣源,精心設(shè)計葉型,增大風舌間隙,適當降低風機轉(zhuǎn)速,改進蝸殼設(shè)計凈化來流及盡量減少二次流損失等設(shè)計原則,采用有限差分法計算進風口和葉輪輪蓋型線,并以葉輪進口處氣流順暢均勻作為優(yōu)化判據(jù)進行了風口優(yōu)化設(shè)計。再結(jié)合原有的風機葉輪、蝸殼等優(yōu)化設(shè)計方法,綜合葉輪、蝸殼、進風口三者一體化的優(yōu)化設(shè)計程序,得出氣動略圖曲線,實踐證明,它既能保證風壓、風量,又能保證較高的效率、較低的比噪聲和較小的風機尺寸。
