今天想向大家介绍一下绕丝筛管。
筛管顾名思义，就是进行过滤，主要用于防砂，又称防砂管，在世界范围内被广泛应用于油、气、水井防砂工业中，其在水井工业中的地位尤其突出，是各种水资源过滤筛管中应用最为广泛的一种。
绕丝筛管采用世界先进的全绕焊生产工艺，应用特制梯形丝绕组在呈圆周式排列的一组支撑丝上焊制而成。
绕丝筛管主要特点有：
1、结构坚固、孔隙率高、缝隙尺寸精确。特别适用于水井的细砂和粉砂地层。
2、容易反冲洗、使用寿命长、安全可靠、综合成本低。
3、孔隙率较高。
4、运行成本低，孔隙率高的滤水管更有利于地下水的渗入。充沛的水量使得水位的降深减小，从而减少能量消耗。特别适用于水井的细砂和粉砂地层。
5、减小泵的磨损，在同等条件下，较高的孔隙率使得地下水在渗入滤水管时的速度较渗入其它过滤装置时的速度要慢的多，这样就避免沙子在较大的水压下进入筛管，减小水泵磨损。
6、延长水井的使用寿命，相对而言，地下水渗入孔隙率高的滤水管更容易一些，水流速度低，延长水井的使用寿命。
Today I'd like to introduce you to the wire wound screen.
screen as the name implies, is mainly used for filtering, sand, and sand control, is widely used in oil and gas wells and sand industry in the world, its position in the water industry is especially prominent, various water resources screen in one of the most widely used.
wire screen adopts the world advanced all around the welding production process, application of special wire winding in a trapezoidal support group arranged on the periphery of round wire welded.
The main characteristics of wire wound screen are:
1, solid structure, high porosity, accurate slot size. Especially suitable for fine sand and silt formation.
2, easy backwashing, long service life, safe and reliable, low comprehensive cost.
3, High porosity
4, low operating cost, high porosity of the filter pipe is more conducive to the infiltration of groundwater. The amount of water makes the water level drop down, thus reducing energy consumption. Especially suitable for fine sand and silt formation.
5, reduce the wear of the pump, in the same conditions, high porosity and the groundwater in the infiltration of the filter speed is infiltrated into the other filtering device the speed much slower, thus avoiding the sand into the sieve tube in the larger water pressure, reduce the pump wear.
6, prolong the service life of the water well, relatively speaking, the infiltration of groundwater into the high porosity of the filter pipe is easier, the flow rate is low, prolong the service life of the water well.
