楔形丝网
绕线管由V型线和支撑杆组成,采用世界上最先进的焊接工艺,每个交点具有焊接连接,结构坚固,机械性能好。 V形截面,避免堵塞,同时确保水流。连续间隙具有较大的水面积,同时降低了地下水的渗透率,避免了砂中较大的水压进入管内,形成了较好的滤砂。差距也可以根据不同的地质情况而改变。
绕线管(约翰逊管)的优点特点:
1.应用梯形电线,使屏幕间隙形成V形开口。设计比其他形式的产品运行更有效率,确保水资源顺利流通。
2.梯形丝连续卷绕在支撑线的圆形布置中,形成连续高密度均匀的间隙,确保筛网开口面积和不堵塞,并避免沉积物积聚的高密度,以提高提高生产效率,延长井口寿命,提供保证。
3.绕组和所有支撑线通过焊接连接,耐用,使用寿命更长。
4.根据实际需要设计的纵向排列的支撑丝和筛网的连续形式的间隙,使产品具有较高的压缩性能。
5.电线尺寸和连接也可根据不同需要生产
