<p> (一)原理 </p> <p> 測量風(fēng)道中氣體的壓力應(yīng)在氣流比較平穩(wěn)的管段進行。測試中需測定氣體的靜壓、動壓和全壓。測氣體全壓的孔口應(yīng)迎著風(fēng)道中氣流的方向，測靜壓的孔口應(yīng)垂直于氣流的方向。用U形壓力計測全壓和靜壓時，另一端應(yīng)與大氣相通(用傾斜微壓計在正壓管段測壓時，管的一端應(yīng)與大氣相通，在負壓管段測壓時，容器開口端應(yīng)與大氣相通)。因此壓力計上讀出的壓力，實際上是風(fēng)道內(nèi)氣體壓力與大氣壓力之間的壓差(即氣體相對壓力)。大氣壓力一般用大氣壓力表測定。由于全壓等于動壓與靜壓的代數(shù)和，可只測其中兩個值，另一值通過計算求得。

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，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，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，為減少誤差可適當(dāng)增加測點。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。
