風(fēng)扇轉(zhuǎn)速 </p> <p> 風(fēng)扇轉(zhuǎn)速是指風(fēng)扇扇葉每分鐘旋轉(zhuǎn)的次數(shù)，單位是rpm。風(fēng)扇轉(zhuǎn)速由電機內(nèi)線圈的匝數(shù)、工作電壓、風(fēng)扇扇葉的數(shù)量、傾角、高度、直徑和軸承系統(tǒng)共同決定。轉(zhuǎn)速和風(fēng)扇質(zhì)量沒有必然的聯(lián)系。風(fēng)扇的轉(zhuǎn)速可以通過內(nèi)部的轉(zhuǎn)速信號進行測量，也可以通過外部進行測量。 </p> <p> 隨著應(yīng)用情況與環(huán)境溫度的變化，有時需要不同轉(zhuǎn)速風(fēng)扇來滿足需求。一些廠商特意設(shè)計出可調(diào)節(jié)風(fēng)扇轉(zhuǎn)速的散熱風(fēng)扇，分手動和自動兩種。手動的主要是讓用戶可以在冬天使用低轉(zhuǎn)速獲得低噪音，夏天時使用高轉(zhuǎn)速獲得好的散熱效果。自動類調(diào)溫散熱器一般帶有一個溫控感應(yīng)器，能夠根據(jù)當(dāng)前的工作溫度自動控制風(fēng)扇的轉(zhuǎn)速，溫度高則提高轉(zhuǎn)速，溫度低則降低轉(zhuǎn)速，以達到一個動態(tài)的平衡，從而讓風(fēng)噪與散熱效果保持一個比較好的結(jié)合點。衢州日立專配風(fēng)扇風(fēng)扇的在進行挑選時有什么技巧嗎？</p><div

風(fēng)速是風(fēng)扇重要的性能指標(biāo)之一,與重要的兩項性能指標(biāo)之一風(fēng)量關(guān)系密切。 </p> <p> 風(fēng)速即風(fēng)扇出風(fēng)口或進風(fēng)口的空氣流動速度,單位一般為m/s;*是某一位置的速度數(shù)值,不能完全體現(xiàn)風(fēng)扇的性能。風(fēng)速在不同位置數(shù)值可能有較大差異,且平均值難以計算,一般不用來表示風(fēng)扇的性能。 </p> <p> 風(fēng)速的高低主要取決于扇葉的形狀、面積、高度以及轉(zhuǎn)速。扇葉形狀設(shè)計、面積、高度的影響較為復(fù)雜;風(fēng)扇轉(zhuǎn)速越快,風(fēng)速越快,則是顯而易見的常識。 </p> <p> <br /> </p><p> 風(fēng)扇主軸直徑:由于電機與軸承的存在,軸流風(fēng)扇主軸所在的中心部分難免一定無氣流通過的盲區(qū),主軸直徑便決定著此盲區(qū)的大小。主軸直徑的大小則主要取決于風(fēng)扇電機的功率——大功率的電機需要更大的定子繞組線圈,必然占用更多的空間,在無法縱向擴展(增加高度)的情況下,便只好橫向擴展(增大面積)。 </p> <p> 風(fēng)扇葉片光滑度:這是一項非設(shè)計因素影響的指標(biāo),基本上取決于生產(chǎn)者的模具成形與后期處理工藝。在設(shè)計曲線之外,葉片上的不平整會在旋轉(zhuǎn)中產(chǎn)生紊流,增加摩擦,降低風(fēng)扇效率,折損風(fēng)扇性能,增大工作噪音。因此,應(yīng)對葉片表面的光滑度嚴格控制,如果所購產(chǎn)品處理不佳,則應(yīng)考率采用手工打磨等后續(xù)手段彌補。 </p> <p> <br /> 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。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

扇葉制造材料：風(fēng)扇內(nèi)的風(fēng)機葉輪是很長的，這樣的一個圓桶狀的扇葉如果使用劣質(zhì)材料制造，是可以節(jié)省不少成本，可是轉(zhuǎn)不了多久，就會發(fā)生變形，整個扇葉不再是在一條直線上，而是中間下垂，您可以想象，這樣下垂的扇葉在轉(zhuǎn)起來后，是何等的高噪音，并且會帶動整個風(fēng)幕機震動！ </p> <p> 電機：風(fēng)輪是要靠電動機來使之運轉(zhuǎn)的，如果電機質(zhì)量差，無法正常運轉(zhuǎn)或者啟動乏力，都是不行的，要是電機的質(zhì)量差，那還會聽見電機發(fā)出的“嗡嗡”聲，更是一種折磨。電梯風(fēng)扇的作用是什么？衢州日立專配風(fēng)扇</p><p

除了散熱效果之外，風(fēng)扇的工作噪音也是人們普遍關(guān)注的問題。風(fēng)扇噪音是風(fēng)扇工作時產(chǎn)生雜音的大小，受多方面因素影響，單位為分貝(dB)。測量風(fēng)扇的噪聲時需要在噪聲小于17dB的消音室中進行，距離風(fēng)扇一米，并沿風(fēng)扇轉(zhuǎn)軸的方向?qū)?zhǔn)風(fēng)扇的進氣口，采用A加權(quán)的方式進行測量。風(fēng)扇噪聲的頻譜特性也很重要，因此還需要用頻譜儀記錄風(fēng)扇的噪聲頻率分布情況，一般要求風(fēng)扇的噪聲要盡量的小，而且不能存在異音。 </p> <p> 風(fēng)扇噪音與摩擦力、空氣流動有關(guān)。風(fēng)扇轉(zhuǎn)速越高、風(fēng)量越大，造成的噪音也會越大，另外風(fēng)扇自身的震動也是不可忽視的因素。當(dāng)然***的風(fēng)扇的自身震動會很小，但前面兩個者卻是難以克服的。要解決這個問題，我們可以嘗試使用尺寸較大的風(fēng)扇。應(yīng)在在風(fēng)量相同的情況下，大風(fēng)扇在較低轉(zhuǎn)速時的工作噪聲要小于小風(fēng)扇在高轉(zhuǎn)速時的工作噪聲。另外一個我們?nèi)菀缀雎缘囊蛩厥秋L(fēng)扇的軸承。由于風(fēng)扇高速轉(zhuǎn)動時轉(zhuǎn)軸和軸承之間要摩擦碰撞，所以也是風(fēng)扇噪聲的一個主要來源。通力專配風(fēng)扇等級</p><p
