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 channel)，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業(yè)灌溉用渠道。我公司專業(yè)生產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，把明渠內流量的大小轉成液位的高低。測量明渠內水的流量。如灌渠、污水溝、城市下水道的流量。材質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加工B1800型巴歇

2、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)進入巴歇爾槽。

3、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。使水流全部流經巴歇爾槽的計量部位。巴歇爾槽的計量部位是槽內喉道段。巴歇爾槽構造圖巴歇爾槽構造尺寸（單位：米）類別序號喉道段收縮段擴散段墻高bLNB1L1LaB2L2KD小型10.0250.0760.0290.1670.3560.2370.0930.2030.0190.2320.0510.1140.0430.2140.4060.27101350.2540.0220.2630.0760.1520.0570.2590.4570.3050.1780.3050.0250.4640.1
