風(fēng)量單位時間內(nèi)通過風(fēng)扇出風(fēng)口(或進(jìn)風(fēng)口)截面的空氣體積,單位一般為cfm,即立方英尺每分-cubic feet per minute,或cmm,即立方米每分- cubic metres per minute。風(fēng)量是風(fēng)扇性能的整體衡量指標(biāo),不受到尺寸、結(jié)構(gòu)、方式的限制,也不限于直流無刷風(fēng)扇,可適用于任何空氣導(dǎo)流設(shè)備。 </p> <p> 風(fēng)量=平均風(fēng)速x 過風(fēng)面積?？梢?風(fēng)扇風(fēng)量的大小基本取決于風(fēng)速的高低與過風(fēng)面積的大小。過風(fēng)面積相同,風(fēng)速越高,風(fēng)量越大;風(fēng)速相同,過風(fēng)面積越大,風(fēng)量越大 </p> <p> <br /> </p><p> 新穎風(fēng)扇 </p> <p> 時控電風(fēng)扇 </p> <p>

美國通用電器公司研制出的這種用聲控電風(fēng)扇裝有微型電子，只需在不超過3米的地方連續(xù)拍手2次，電風(fēng)扇就會自動運(yùn)轉(zhuǎn);若再連續(xù)拍手3次，電風(fēng)扇又會自動停轉(zhuǎn)。 </p> <p> 冷氣風(fēng)電風(fēng)扇 </p> <p> 歐洲市場上推出了一種風(fēng)扇與冰箱相結(jié)合的新型電風(fēng)扇，其風(fēng)扇有一個制冷機(jī)芯，機(jī)芯的中心圓筒中有混合液體，將此機(jī)芯置于冰箱中3個小時后取出配用，即可吹出冷風(fēng)，給人以有冷氣吹來的感覺。 </p> <p> <br /> 風(fēng)扇的工作方式是怎樣的？</p><div

1、橫流風(fēng)扇是使用一個比較長的圓桶狀扇葉輪進(jìn)行工作，這個圓桶狀扇葉的口徑都比較大，因為口徑大，才能在保證整體空氣循環(huán)量的基礎(chǔ)上使用比較低的轉(zhuǎn)速，從而降低由于高速運(yùn)轉(zhuǎn)帶來的噪音。 </p> <p> 2、風(fēng)扇的葉輪做過動平衡：正像汽車輪子要做動平衡一樣，橫流風(fēng)扇的風(fēng)輪也需要做這個工作，簡單來說，就是保持風(fēng)輪在運(yùn)轉(zhuǎn)狀態(tài)下的平衡，減低噪音，并且延長風(fēng)機(jī)壽命。動平衡是一件消耗工夫的工作，實際上，結(jié)果可能就是在風(fēng)輪的某個部位加上配重片而已?？墒牵烤乖谀膫€位置加？加多大？這都直接影響到橫流風(fēng)扇的使用壽命。風(fēng)扇的轉(zhuǎn)速越快散熱效果越好，風(fēng)扇的尺寸越大風(fēng)量越大，散熱效果越好。麗水訊達(dá)專配330型風(fēng)扇</p><p style="text-indent:25px">風(fēng)扇的發(fā)展歷程是怎樣的？電梯橫流風(fēng)扇哪里買</p><p> 風(fēng)扇消除噪音 </p> <p> 折疊一、潤滑軸承 </p> <p> 風(fēng)扇轉(zhuǎn)運(yùn)主要的部件就是軸承，時間長了缺乏潤滑油，這樣高速轉(zhuǎn)動時就會產(chǎn)生噪聲。因此，我們只需要在風(fēng)扇軸承上滴幾滴潤滑油，如果沒有使用縫紉機(jī)代替也可以。但是注意千萬不要使用食用油來替代，因為其顆粒比較大，容易對軸承產(chǎn)生傷害。 </p> <p> 折疊二、固定扇葉 </p> <p> 震動噪音亦是風(fēng)扇噪音的一個重要組成部分，因為葉片在軸承上的松動以及軸承磨損導(dǎo)致間隙變大等，因此只需要拆下分扇，把螺絲鈕緊，這樣牢牢固定之后，就不會再震動。 </p> <p> 折疊三、打磨扇葉 </p> <p> 另外使用質(zhì)量較差的散熱風(fēng)扇，在制作這類風(fēng)扇時由于工藝上的缺點，扇葉的重心可能沒有處在軸心上，形成""偏心""，使用時間一長，風(fēng)扇的""偏心""現(xiàn)象會變得越來越嚴(yán)重，這不僅會產(chǎn)生噪音，嚴(yán)重的還可能損壞CPU。對此，可以將共拆下來，然后用細(xì)線吊在其中心位置，待其靜止后看其向哪一方向下沉，把下沉的一端在砂輪上輕磨幾下，再進(jìn)行測試，一直待風(fēng)扇能夠處在水平位置之后再將其安裝上去即可。
