巴氏計量槽-選型

1、巴歇爾槽非滿管狀態(tài)流動的水路稱作明渠（open cha nn el），明渠流量計的應用場所有城市供水引水渠、火電廠冷卻水引水和排水渠、污水治理流入和排放渠、工礦企業(yè)廢水排放以及水利工程和農(nóng)業(yè)灌溉用渠道。我公司專業(yè)生產(chǎn)與明渠流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）。用途與明渠流量計（WL-1A型超聲波明渠流量計）配合使用，把明渠內(nèi)流量的大小轉(zhuǎn)成液位的高低。測量明渠內(nèi)水的流量。如灌渠、污水溝、城市下水道的流量。材質(zhì)玻璃纖維不飽和聚酯復合材料（玻璃鋼）。測量范圍流量范圍: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* 為六盤水污水廠生產(chǎn)加工 B1800型

2、巴歇爾槽，最大流量達到10000立方米/小時* 為青島麥島污水處理廠加工 B600型巴歇爾槽，流量達到3300立方米/小時* 為北京密云環(huán)保局、云南文山州環(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)保局等下屬的一百多家企業(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 ，使水流進入巴歇爾槽不出現(xiàn)偏流。巴歇爾槽通水后，水的流態(tài)要自由流。巴歇爾槽的淹沒度要小于規(guī)定的臨界淹沒度。巴歇爾槽的上游應有大于 5倍渠道寬的平直段，使水流能平穩(wěn)進入

3、巴歇爾槽。即沒有左右偏流，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。與渠道側壁、渠底連結要緊密，不能漏水。使水流全部流經(jīng)巴歇爾 槽的計量部位。巴歇爾槽的計量部位是槽內(nèi)喉道段。上諭觀劇戌木性hi界悔炭F留水帆-|水価1打下燃木佩下確水也値 F龍找.育自圖自由流與淹沒流巴歇爾槽構造圖200.D=&0IVa：二：士D'j1水鉉零嵐K11a11?g收姆投L1喉逍段L擴墩段12La円_ - " - 器1111< EKOmi 說明；圈示巴龜爾糟用破踽鋼制做i內(nèi)尺寸要準確；bLILaLL2bl炭DNKj尺寸單位；価內(nèi)表面慕卅膺.平整； 壁厚要大于8血
