巴氏计量槽选型

1、巴氏计量槽选型巴氏计量槽选型3/3巴氏计量槽选型巴歇尔槽非满管状态流动的水道称作明渠(openchannel)，明渠流量计的应用地方有城市供水引沟渠、火电厂冷却水引水和排沟渠、污水治理流入和排放渠、工矿公司废水排放以及水利工程和农业浇灌用渠道。我公司专业生产与明渠流量计配套使用的各样规格的量水堰槽（巴歇尔槽）、堰板（三角堰，矩形堰）。用途与明渠流量计(WL-1A型超声波明渠流量计)配合使用，把明渠内流量的大小转成液位的高低。丈量明渠内水的流量。如灌渠、污沟渠、城市下水道的流量。材质玻璃纤维不饱和聚酯复合资料（玻璃钢）。丈量范围流量范围:10升/秒10立方米/秒(由配用巴歇尔槽的规格决定)典型事

2、例?为六盘水污水厂生产加工B1800型巴歇尔槽，最大流量达到10000立方米/小时?为青岛麦岛污水办理厂加工B600型巴歇尔槽，流量达到3300立方米/小时为北京密云环保局、云南文山州环保局、包头市环保局、大连市环保局、天津环保局、武汉环保局、山西运城环保局等手下的一百多家公司供给了各样规格（B51、B76、B152、B228、B250、B600、B1500、B1800）的堰槽、堰板(巴歇尔槽和三角堰、矩形堰).注意事项巴歇尔槽的中心线要与渠道的中心线重合,使水流进入巴歇尔槽不出现偏流。巴歇尔槽通水后，水的流态要自由流。巴歇尔槽的吞没度要小于规定的临界吞没度。巴歇尔槽的上游应有大于5倍渠道宽的

3、平直段，使水流能安稳进入巴歇尔槽。即没有左右偏流，也没有渠道坡降形成的冲力。（拜见以下列图）巴歇尔槽安装在渠道上要坚固。与渠道侧壁、渠底连接重要密，不可以漏水。使水流所有流经巴歇尔槽的计量部位。巴歇尔槽的计量部位是槽内喉道段。巴歇尔槽结构图巴歇尔槽结构尺寸（单位：米）类序喉道段缩短段扩散段墙高别号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
