G、Y6-41系列通風(fēng)機(jī)所用的設(shè)計(jì)方法:選擇合適的風(fēng)機(jī)型式,合理的風(fēng)機(jī)工況,優(yōu)選流型,合理組織氣源,精心設(shè)計(jì)葉型,增大風(fēng)舌間隙,適當(dāng)降低風(fēng)機(jī)轉(zhuǎn)速,改進(jìn)蝸殼設(shè)計(jì)凈化來流及盡量減少二次流損失等設(shè)計(jì)原則,采用有限差分法計(jì)算進(jìn)風(fēng)口和葉輪輪蓋型線,并以葉輪進(jìn)口處氣流順暢均勻作為優(yōu)化判據(jù)進(jìn)行了風(fēng)口優(yōu)化設(shè)計(jì)。再結(jié)合原有的風(fēng)機(jī)葉輪、蝸殼等優(yōu)化設(shè)計(jì)方法,綜合葉輪、蝸殼、進(jìn)風(fēng)口三者一體化的優(yōu)化設(shè)計(jì)程序,得出氣動(dòng)略圖曲線,實(shí)踐證明,它既能保證風(fēng)壓、風(fēng)量,又能保證較高的效率、較低的比噪聲和較小的風(fēng)機(jī)尺寸。
