通風(fēng)管道內(nèi)風(fēng)速及風(fēng)量的測定，是通過測量壓力換算得到。測得管道中氣體的真實(shí)壓力值，除了正確使用測壓儀器外，合理選擇測量斷面、減少氣流擾動對測量結(jié)果的影響很大。測量斷面應(yīng)盡量選擇在氣流平穩(wěn)的直管段上。測量斷面設(shè)在彎頭、三通等異形部件前面(相對氣流流動方向)時(shí)，距這些部件的距離應(yīng)大于2倍管道直徑。當(dāng)測量斷面設(shè)在上述部件后面時(shí)，距這些部件的距離應(yīng)大于4～5倍管道直徑。當(dāng)測試現(xiàn)場難于滿足要求時(shí)，為減少誤差可適當(dāng)增加測點(diǎn)。但是，測量斷面位置距異形部件的**小距離至少是管道直徑的1.5倍。 </p> <p> 測定動壓時(shí)如發(fā)現(xiàn)任何一個(gè)測點(diǎn)出現(xiàn)零值或負(fù)值，表明氣流不穩(wěn)定，該斷面不宜作為測定斷面。如果氣流方向偏出風(fēng)管中心線15°以上，該斷面也不宜作測量斷面(檢查方法：畢托管端部正對氣流方向，慢慢擺動畢托管，使動壓值比較大，這時(shí)畢托管與風(fēng)管外壁垂線的夾角即為氣流方向與風(fēng)管中心線的偏離角)。 </p> <p> 選擇測量斷面，還應(yīng)考慮測定操作的方便和安全。 </p> <p> <br /> 樂清通風(fēng)管道各種通風(fēng)管道怎樣計(jì)算平米？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
