(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。 12v風(fēng)扇廠家電話風(fēng)扇的種類有哪些呢？</p><div style="width:100%;text-align: center;"><img

冬天溫度驟降，對(duì)于散熱風(fēng)扇的使用也是很多的，使用時(shí)的日常維護(hù)，是我們所需要做的事情。在冬天，有些地方的霧霾也是比較大的，當(dāng)然對(duì)于散熱風(fēng)扇來說，灰塵清理也是不可缺少的。當(dāng)散熱風(fēng)扇運(yùn)行的時(shí)候，它是處于高速運(yùn)轉(zhuǎn)的過程的，所以它所積攢的灰塵已經(jīng)可以用鋪天蓋地來形容了。 </p> <p> 那么，了解了問題所在，我們就能夠針對(duì)它給出相應(yīng)的措施了，我們可以將散熱風(fēng)扇所積累的灰塵，給它洗個(gè)澡，就是將散熱風(fēng)扇內(nèi)部所存在的灰塵給清理掉，在設(shè)計(jì)它的時(shí)候，可以安裝一個(gè)過濾器，來過濾灰塵，通過這種方式，也就讓散熱風(fēng)扇可以更長(zhǎng)壽了。 </p><p> 風(fēng)扇選購(gòu) </p> <p> 看隨機(jī)文件每臺(tái)電風(fēng)扇的隨機(jī)文件包括使用說明書、產(chǎn)品合格證、電氣線路圖和裝箱單，購(gòu)買時(shí)要按照裝箱單清查、核對(duì)零部件的數(shù)量和質(zhì)量。 </p> <p> 看網(wǎng)罩和扇葉是否有明顯變形:在裝配好的電風(fēng)扇網(wǎng)罩上，用一支筆指向一個(gè)扇葉比較高點(diǎn)，緩緩移動(dòng)扇葉，其他幾個(gè)扇葉相對(duì)應(yīng)點(diǎn)與筆尖之距離應(yīng)十分相近，再轉(zhuǎn)動(dòng)扇葉，注意觀察轉(zhuǎn)動(dòng)是否輕快靈活，并且可以在任一位置停下。 </p> <p> 看控制機(jī)構(gòu)是否靈活:控制機(jī)構(gòu)包括調(diào)速開關(guān)、定時(shí)旋鈕、搖頭開關(guān)、照明燈開關(guān)等，這些控制機(jī)構(gòu)應(yīng)該操作靈活、接觸可靠。對(duì)調(diào)速檔，不允許有兩擋同時(shí)接通或一擋按不下去的現(xiàn)象。按下停止鍵，各速度擋鍵應(yīng)正常復(fù)位。風(fēng)扇的工作原理是什么？</p>

風(fēng)扇葉端間隙:如何調(diào)整扇葉與外框之間所存在的間隙是風(fēng)扇設(shè)計(jì)中的一大難題。間隙過小會(huì)令此間氣流與葉片、外框發(fā)生摩擦,增大噪音;增大間隙則會(huì)由于反激氣流等影響耳降低風(fēng)扇效率——間隙增大1%,則全壓功率下降約2%。 </p> <p> 風(fēng)扇葉片弧度:扇葉除了在截面上具有一定曲率外,在俯視平面內(nèi)也并非沿著徑向筆直延伸,而是向著旋轉(zhuǎn)方向略有彎曲,呈一定弧度。如果葉片沿徑向筆直延伸,風(fēng)扇旋轉(zhuǎn)所帶動(dòng)的氣流在出風(fēng)口一側(cè)將呈散射狀,送風(fēng)距離短,且“力量”不集中;如現(xiàn)行產(chǎn)品版略帶弧度,則可保證吹出氣流集中在出風(fēng)口正前方的柱狀空間內(nèi),增加送風(fēng)距離與風(fēng)壓。 </p> <p> <br /> 風(fēng)扇存放的地點(diǎn)應(yīng)干燥通風(fēng)避免擠壓。浙江檔位式風(fēng)扇</p><p style="text-indent:25px">震動(dòng)噪音亦是風(fēng)扇噪音的一個(gè)重要組成部分。24v風(fēng)扇訂購(gòu)</p><p> 無噪聲電風(fēng)扇 </p> <p>
