本系列燒結(jié)離心鼓風(fēng)機(jī)系鋼板焊接機(jī)殼，機(jī)殼內(nèi)部采用鋼管支撐筋，外部設(shè)計(jì)有型鋼加強(qiáng)筋，結(jié)構(gòu)合理，剛性好。殼體與軸承箱為同-中心高度，安裝方便，熱脹量影響小，穩(wěn)定性好。采用有限元法計(jì)算程序計(jì)算轉(zhuǎn)子的臨界轉(zhuǎn)速和葉輪強(qiáng)度，準(zhǔn)確可靠，確保機(jī)組的平穩(wěn)運(yùn)行，安全可靠。以高效模型為基本級(jí)，模化設(shè)計(jì)，性能可靠，工況范圍寬。葉輪和機(jī)殼內(nèi)部采用先進(jìn)的防磨措施，使用壽命可提高3~5倍。

The sinter plant fan is of steel plate fabricated casing with steel piping supports inside thecasing and formed steel reinforcement outside the casing, which is reasonable in constructionand characterized by good rigidity.The casing is in the same centre height with the bearingpedestals, which is easy for installation,ess influence from thermal expansion and excellencein stability.Computer software with finite elementmethod is adopted to calculate the critical speed ofrotors and impeller strength,resulting in accuracy andreliability and thus the stable and safe operation oftrain is ensured. Simulation design with high efficientbasic stage model leads reliable performance andwider operating range. Advanced anti-erosionmeasures are taken for impellers and casinginternals, while increasing the
