如果實(shi)驗(yan)室(shi)的通風系統有很(hen)強的噪(zao)聲(sheng)，你(ni)覺(jue)(jue)得你(ni)在(zai)做(zuo)實(shi)驗(yan)的時候會不會受到干擾呢，一般(ban)我(wo)們要將(jiang)實(shi)驗(yan)室(shi)內(nei)的噪(zao)聲(sheng)控制在(zai)55dB(A)，這樣(yang)才會讓人覺(jue)(jue)得舒(shu)服，今(jin)天我(wo)們實(shi)驗(yan)邊臺廠家(jia)就來教大家(jia)如何控制好實(shi)驗(yan)室(shi)通風設備的噪(zao)聲(sheng)問題。

　　在風(feng)(feng)(feng)(feng)機(ji)功(gong)率不大的情況下，可通過在風(feng)(feng)(feng)(feng)機(ji)上方加防雨罩(zhao)來消除(chu)(chu)風(feng)(feng)(feng)(feng)聲(sheng)，在使用大功(gong)率風(feng)(feng)(feng)(feng)機(ji)時一般在風(feng)(feng)(feng)(feng)機(ji)進(jin)出口加消聲(sheng)器(qi)來消除(chu)(chu)風(feng)(feng)(feng)(feng)聲(sheng)，機(ji)械噪聲(sheng)主要靠建隔(ge)音墻、小黑屋或在風(feng)(feng)(feng)(feng)機(ji)進(jin)出口加軟接頭來解決。

　　減(jian)振(zhen)的(de)(de)主(zhu)要方法為風(feng)(feng)(feng)(feng)機底座(zuo)做(zuo)成減(jian)振(zhen)底座(zuo)并安裝(zhuang)減(jian)振(zhen)器或加裝(zhuang)減(jian)振(zhen)墊。電子調風(feng)(feng)(feng)(feng)閥的(de)(de)作用是通(tong)(tong)(tong)過調節每(mei)臺通(tong)(tong)(tong)風(feng)(feng)(feng)(feng)柜的(de)(de)風(feng)(feng)(feng)(feng)管半徑來調節每(mei)臺通(tong)(tong)(tong)風(feng)(feng)(feng)(feng)柜的(de)(de)通(tong)(tong)(tong)風(feng)(feng)(feng)(feng)量，來達到(dao)當(dang)通(tong)(tong)(tong)風(feng)(feng)(feng)(feng)柜開口(kou)面積變(bian)化時保(bao)持表面風(feng)(feng)(feng)(feng)速不變(bian)。

　　排風(feng)(feng)量(liang)(Q)=表面風(feng)(feng)速(su)(su)(vs)×排毒柜開口(kou)面積(ji)。變頻(pin)系(xi)統的(de)作(zuo)用是改變風(feng)(feng)機(ji)的(de)轉(zhuan)速(su)(su)來改變風(feng)(feng)機(ji)的(de)通(tong)(tong)風(feng)(feng)量(liang)，當一套通(tong)(tong)風(feng)(feng)系(xi)統中只有少量(liang)幾臺(tai)通(tong)(tong)風(feng)(feng)柜工作(zuo)時，變頻(pin)系(xi)統自動調(diao)節(jie)風(feng)(feng)機(ji)的(de)轉(zhuan)速(su)(su)，從而改變風(feng)(feng)機(ji)的(de)通(tong)(tong)風(feng)(feng)量(liang)，從而保證通(tong)(tong)風(feng)(feng)柜的(de)面風(feng)(feng)速(su)(su)恒定。

　　以上這(zhe)些就是(shi)實驗(yan)(yan)邊臺廠家今天闡述的(de)如何改變(bian)實驗(yan)(yan)室(shi)通風系統噪聲的(de)問題。
