巴氏計(jì)量槽選型

1、巴氏計(jì)量槽選型巴氏計(jì)量槽選型3/3巴氏計(jì)量槽選型巴歇爾槽非滿管狀態(tài)流動(dòng)的水道稱作明渠(openchannel)，明渠流量計(jì)的應(yīng)用地方有城市供水引溝渠、火電廠冷卻水引水和排溝渠、污水治理流入和排放渠、工礦公司廢水排放以及水利工程和農(nóng)業(yè)澆灌用渠道。我公司專業(yè)生產(chǎn)與明渠流量計(jì)配套使用的各樣規(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(jì)(WL-1A型超聲波明渠流量計(jì))配合使用，把明渠內(nèi)流量的大小轉(zhuǎn)成液位的高低。丈量明渠內(nèi)水的流量。如灌渠、污溝渠、城市下水道的流量。材質(zhì)玻璃纖維不飽和聚酯復(fù)合資料（玻璃鋼）。丈量范圍流量范圍:10升/秒10立方米/秒(由配用巴歇爾槽的規(guī)格決定)典型事

2、例?為六盤水污水廠生產(chǎn)加工B1800型巴歇爾槽，最大流量達(dá)到10000立方米/小時(shí)?為青島麥島污水辦理廠加工B600型巴歇爾槽，流量達(dá)到3300立方米/小時(shí)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(yùn)城環(huán)保局等手下的一百多家公司供給了各樣規(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(xiàng)巴歇爾槽的中心線要與渠道的中心線重合,使水流進(jìn)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。巴歇爾槽的吞沒度要小于規(guī)定的臨界吞沒度。巴歇爾槽的上游應(yīng)有大于5倍渠道寬的

3、平直段，使水流能安穩(wěn)進(jìn)入巴歇爾槽。即沒有左右偏流，也沒有渠道坡降形成的沖力。（拜見以下列圖）巴歇爾槽安裝在渠道上要堅(jiān)固。與渠道側(cè)壁、渠底連接重要密，不可以漏水。使水流所有流經(jīng)巴歇爾槽的計(jì)量部位。巴歇爾槽的計(jì)量部位是槽內(nèi)喉道段。巴歇爾槽結(jié)構(gòu)圖巴歇爾槽結(jié)構(gòu)尺寸（單位：米）類序喉道段縮短段擴(kuò)散段墻高別號(hào)bLNB1L1LaB2L2KD10.0250.0760.0290.1670.0930.2030.0190.2320.0510.1140.0430.21401350.2540.0220.26小型30.0760.1520.0570.2590.1780.3050.0250.4640.1520.3050.11
