不銹鋼巴歇爾槽的作用

更新時間:2016-07-21  |  點擊率:815

不銹鋼巴歇爾槽  型號:HAD-4

非滿管狀態(tài)動的水路稱作明渠(open channel),明渠量計的應(yīng)用場所有城市供水引水渠、火電廠冷卻水引水和排水渠、污水治理入和排放渠、礦企業(yè)廢水排放以及水利程和農(nóng)業(yè)灌溉用渠道。我公司業(yè)與明渠量計配套使用的各種規(guī)格的量水堰槽(巴歇爾槽)、堰板(三角堰,矩形堰)。

用途

與明渠量計(HAD-ZM-GM 型聲波明渠量計)配合使用,把明渠內(nèi)量的大小轉(zhuǎn)成液位的低。測量明渠內(nèi)水的量。如灌渠、污水溝、城市下水道的量。

材質(zhì)

PVC  聚丙烯  不銹剛                                                                                     

測量范圍

量范圍:10升/秒~10立方米/秒(由配用巴歇爾槽的規(guī)格決定)

典型案例

  • 為六盤水污水廠B1800型巴歇爾槽,zui大量達(dá)到10000立方米/小時
    • 為青島麥島污水處理廠B600型巴歇爾槽,量達(dá)到3300立方米/小時
      • 為北京密云環(huán)保局、云南*州環(huán)保局、包頭市環(huán)保局、大連市環(huán)保局、天津環(huán)保局、武漢環(huán)保局、山西運城環(huán)保局等下屬的百多家企業(yè)提供了各種規(guī)格(B51、B76、B152、B228、B250、B600、B1500、B1800)的堰槽、堰板(巴歇爾槽和三角堰、矩形堰).

      注意事項

      • 巴歇爾槽的中心線要與渠道的中心線重合,使水入巴歇爾槽不出現(xiàn)偏。
        • 巴歇爾槽通水后,水的態(tài)要自由。巴歇爾槽的淹沒度要小于規(guī)定的臨界淹沒度。
          • 巴歇爾槽的上游應(yīng)有大于5倍渠道寬的平直段,使水能平穩(wěn)入巴歇爾槽。即沒有左右偏,也沒有渠道坡降形成的沖力。(參見下圖)
            • 巴歇爾槽安裝在渠道上要牢固。與渠道側(cè)壁、渠底連結(jié)要緊密,不能漏水。使水經(jīng)巴歇爾槽的計量位。巴歇爾槽的計量位是槽內(nèi)喉道段。
