(5)風(fēng)扇的空間設(shè)計(jì)。為了風(fēng)扇的效率、噪音，必須保證扇葉和風(fēng)扇外殼的距離為5~10mm。風(fēng)扇的扇葉必須靠近Tongue以獲得比較好的效率。衢州風(fēng)扇聯(lián)系方式風(fēng)扇距離人比較好控制在大于2米。</p><div style="width:100%;text-align: center;"><img

<p> 風(fēng)扇轉(zhuǎn)運(yùn)主要的部件就是軸承，時(shí)間長(zhǎng)了缺乏潤(rùn)滑油，這樣高速轉(zhuǎn)動(dòng)時(shí)就會(huì)產(chǎn)生噪聲。因此，我們只需要在風(fēng)扇軸承上滴幾滴潤(rùn)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?yàn)槠漕w粒比較大，容易對(duì)軸承產(chǎn)生傷害。 </p> <p> 折疊二、固定扇葉 </p> <p> 震動(dòng)噪音亦是風(fēng)扇噪音的一個(gè)重要組成部分，因?yàn)槿~片在軸承上的松動(dòng)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(huì)再震動(dòng)。 </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(shí)由于工藝上的缺點(diǎn)，扇葉的重心可能沒有處在軸心上，形成""偏心""，使用時(shí)間一長(zhǎng)，風(fēng)扇的""偏心""現(xiàn)象會(huì)變得越來越嚴(yán)重，這不僅會(huì)產(chǎn)生噪音，嚴(yán)重的還可能損壞CPU。對(duì)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(cè)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。 </p> <p> <br /> 風(fēng)扇用久以后，扇葉的下面很容易沾上很多灰塵。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="電梯風(fēng)扇,風(fēng)扇"
