巴氏计量槽选型

1、巴歇尔槽非满管状态流动的水路称作明渠open channel,明渠流量计的应用场所有城市供水引水渠、火电厂 冷却水引水和排水渠、污水治理流入和排放渠、工矿企业废水排放以及水利工程和农业灌溉用渠道.我公司 专业生产与明渠流量计配套使用的各种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上下.测量明 渠内水的流量.如灌渠、污水沟、城市下水道的流量.材质玻璃纤维不饱和聚酯复合材料玻璃钢.测量范围流量范围:10升/秒10立方米/秒由配用巴歇尔槽的规格决定典型案例为六盘水污水厂生产加工 B1800型巴歇尔槽,最大流量到达 1

2、0000立方米/小时,为青岛麦岛污水处理厂加工 B600型巴歇尔槽,流量到达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、山西运城环保局等下属的一百多家企业提供了各种规格B51、B76、 B152 、 B228、B250 、B600、B1500、B1800 的堰槽、堰板巴歇尔槽和三角堰、矩形堰.考前须知,巴歇尔槽的中央线要与渠道的中央线重合,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.巴歇尔槽的淹没度要小于规定的临界淹没度.,巴歇尔槽的上游应有大于 5倍渠道宽的平直段,使水流能平稳进入巴歇尔槽.即没有左右偏流

3、,也没有渠道坡降形成的冲力.参见下列图,巴歇尔槽安装在渠道上要牢固.与渠道侧壁、渠底连结要紧密,不能漏水.使水流全部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.巴歇尔槽构造图巴歇尔槽构造尺寸单位：米类别序号喉道段收缩段扩散段墙高bLNB1L1LaB2L2KD10.0250.0760.0290.1670.356 0.2370.0930.2030.0190.2320.0510.1140.0430.2140.406 0.27101350.2540.0220.26小30.0760.1520.0570.2590.457 0.3050.1780.3050.0250.46型40.1520.305
