降低YBF電機通風噪聲(sheng)主要(yao)從克制聲(sheng)源及消聲(sheng)兩(liang)方面采用方法(fa)。

1.合理判定涼(liang)爽  

  由以上分(fen)析得知，涼爽對(dui)通風噪(zao)聲影響(xiang)較大(da)。

2.選擇適合的電(dian)扇(shan)類型(xing)及標(biao)準    

  從(cong)降(jiang)低噪聲角度啟航，軸流式(shi)(shi)優于離心式(shi)(shi)，離心式(shi)(shi)中又(you)往后傾式(shi)(shi)為(wei)好；在可回轉的離心式(shi)(shi)電(dian)扇中，選盆(pen)式(shi)(shi)電(dian)扇有利。

3.按空氣(qi)動力學合理地描繪風路(lu)    

   YBF電(dian)(dian)機的(de)(de)進、出風(feng)口、風(feng)罩(zhao)、擋風(feng)板、散(san)熱片、端蓋、機座及(ji)其上的(de)(de)吊攀、接(jie)線(xian)盒座、底(di)座輻板以及(ji)電(dian)(dian)扇(shan)(shan)的(de)(de)葉片形狀(zhuang)等(deng)都(dou)要(yao)按空(kong)(kong)氣(qi)動力(li)學原理(li)描繪：風(feng)路(lu)通暢；障礙物表(biao)面盡量描繪成流(liu)(liu)線(xian)型；避免簡略發作顫動的(de)(de)零件在風(feng)路(lu)中(zhong)出現。離(li)心式(shi)電(dian)(dian)扇(shan)(shan)緣與風(feng)罩(zhao)間(jian)的(de)(de)空(kong)(kong)地(di)不宜過小，不然會(hui)發作“消聲”，但(dan)忒大又(you)會(hui)使回風(feng)的(de)(de)渦流(liu)(liu)聲增大；軸流(liu)(liu)式(shi)電(dian)(dian)扇(shan)(shan)的(de)(de)外徑(jing)與風(feng)罩(zhao)間(jian)的(de)(de)徑(jing)向空(kong)(kong)地(di)對噪(zao)聲影(ying)響很大，因此(ci)空(kong)(kong)地(di)對氣(qi)流(liu)(liu)功(gong)用——風(feng)壓，風(feng)量及(ji)電(dian)(dian)扇(shan)(shan)的(de)(de)氣(qi)流(liu)(liu)功(gong)率均有較大的(de)(de)影(ying)響，YBF電(dian)(dian)機多(duo)少(shao)錢(qian)，所(suo)以選擇時應慎重。此(ci)空(kong)(kong)地(di)小，氣(qi)流(liu)(liu)功(gong)用好，但(dan)噪(zao)聲大；反之亦(yi)然。

  我們日(ri)常(chang)使用(yong)的(de)防爆電機(ji)(ji)(ji)整機(ji)(ji)(ji)壽命都(dou)是比較長(chang)的(de)，出現問題的(de)一般都(dou)是一些可裝卸的(de)防爆電機(ji)(ji)(ji)配件，更(geng)換之后還是可以正常(chang)使用(yong)的(de)，也(ye)免去了更(geng)換電機(ji)(ji)(ji)昂貴的(de)費(fei)用(yong)。

   YBF3系列風機防爆電(dian)(dian)機中比較(jiao)常更(geng)(geng)(geng)換的(de)配(pei)件(jian)包括電(dian)(dian)機端蓋，接線盒，YBF電(dian)(dian)機廠(chang)家(jia)，扇葉，電(dian)(dian)機外殼，喇叭(ba)咀，電(dian)(dian)機軸承等配(pei)件(jian)，電(dian)(dian)機更(geng)(geng)(geng)換的(de)費用遠比配(pei)件(jian)要(yao)多的(de)多，但是(shi)(shi)值得注意的(de)是(shi)(shi)我(wo)們所需要(yao)更(geng)(geng)(geng)換的(de)配(pei)件(jian)必須要(yao)配(pei)套符合(he)機器型號，盡量的(de)還是(shi)(shi)找(zhao)原廠(chang)家(jia)進(jin)行更(geng)(geng)(geng)換，我(wo)們的(de)一些客戶(hu)就有(you)更(geng)(geng)(geng)換電(dian)(dian)機配(pei)件(jian)的(de)時候型號弄不清(qing)楚(chu)或者是(shi)(shi)原廠(chang)家(jia)有(you)找(zhao)對而(er)無法(fa)進(jin)行更(geng)(geng)(geng)換的(de)。
