style="text-indent:25px">風(fēng)機(jī)歷史：1862年，英國(guó)的圭貝爾發(fā)明離心風(fēng)機(jī)，其葉輪、機(jī)殼為同心圓型，機(jī)殼用磚制，木制葉輪采用后向直葉片，效率光為40%左右，主要用于礦山通風(fēng)。1892年法國(guó)研制成橫流風(fēng)機(jī)；1898年，愛爾蘭人設(shè)計(jì)出前向葉片的西羅柯式離心風(fēng)機(jī)，并為各國(guó)所普遍采用；19世紀(jì)，軸流風(fēng)機(jī)已應(yīng)用于礦井通風(fēng)和冶金工業(yè)的鼓風(fēng)，但其壓力光為100～300帕，效率光為15～25%，直到二十世紀(jì)40年代以后才得到較快的發(fā)展。1935年，德國(guó)首先采用軸流等壓風(fēng)機(jī)為鍋爐通風(fēng)和引風(fēng)。1948年，丹麥制成運(yùn)行中動(dòng)葉可調(diào)的軸流風(fēng)機(jī)；旋軸流風(fēng)機(jī)、子午加速軸流風(fēng)機(jī)、斜流風(fēng)機(jī)和橫流風(fēng)機(jī)；1874年成立的Clarage公司，于1997年被美國(guó)雙城風(fēng)機(jī)集團(tuán)并購(gòu)，成為至今較老的風(fēng)機(jī)制造商之一，風(fēng)機(jī)的發(fā)展也都獲得了長(zhǎng)足進(jìn)步。1880年，人們?cè)O(shè)計(jì)出用于礦井排送風(fēng)的蝸形機(jī)殼，和后向彎曲葉片的離心風(fēng)機(jī)，結(jié)構(gòu)已比較完善了。1892年法國(guó)研制成橫流風(fēng)機(jī)。</p><p style="text-indent:25px">對(duì)多翼離心風(fēng)機(jī)的性能測(cè)試方法做簡(jiǎn)要說明，以電動(dòng)機(jī)Y174L-3為例，要求風(fēng)機(jī)直接與電動(dòng)機(jī)聯(lián)接并認(rèn)為電動(dòng)機(jī)的轉(zhuǎn)速為其額定值。初步是進(jìn)行現(xiàn)場(chǎng)測(cè)量，測(cè)試內(nèi)容有大氣壓力、平面干濕球溫度、平面面積、進(jìn)出口風(fēng)筒接口的長(zhǎng)度，芯筒面積等，把這些數(shù)據(jù)記錄在表格內(nèi)，為后續(xù)計(jì)算做準(zhǔn)備。第二步是測(cè)電動(dòng)機(jī)數(shù)據(jù)，測(cè)得電壓為382V，電流為30.5A，電動(dòng)機(jī)輸入功率為18Kw，再把此型號(hào)的電動(dòng)機(jī)的標(biāo)牌數(shù)據(jù)進(jìn)行記錄。第三步是計(jì)算系統(tǒng)附加阻力，這里要注意，圖4-1、圖4-2示出4段彎筒的半徑與直徑之比為1、彎管與風(fēng)機(jī)進(jìn)口間的風(fēng)筒長(zhǎng)度為直徑的0.886倍、速度為13.626m/s時(shí)，系統(tǒng)附加阻力曲線S適用，且在1.43kg/m3時(shí)。較后把上述數(shù)據(jù)換算成規(guī)定條件，即風(fēng)機(jī)出口速度、風(fēng)機(jī)出口動(dòng)壓、風(fēng)機(jī)靜壓和風(fēng)機(jī)所需軸功率。風(fēng)機(jī)發(fā)展：特別是中國(guó)加入WTO后，增加風(fēng)機(jī)出口是完全可能的。</p><div
