wedge wire screen pipe casing slotted liner for water filter
|
The Wedge Wire screen pipe casing slotted liner for water filter has a wide range of wire and rod shapes make it possible to achieve the optimum balance of strength, open area, abrasion resistance and dewatering/separation efficiency.
The V-shaped wire can be made in different height and width to address various strength application, meanwhile, the spacing of individual slots can be varied during fabrication if geologic conditions , equire these variations in a screen's construction.
1) Screens with high open area are more suitable for the construction of high-quality water wells, oil wells and gas wells.
2) Low cost operation
Screens with high open area shall favor groundwater infiltration. Abundant water shall reduce the water level’s down, thus to save energy consumption
3) Reduce the abrasion of the pump
Under the same condition, high open area can make the speed of groundwater’s entering into the screen much slower than any other filtration apparatus, which will avoid sand’s entering into screen because of high pressure, thus reduce the abrasion of the pump.
4) Extend the life span of wells
Comparatively, groundwater’s entering into screen with higher open area is much easier than the entering into lower open area screen. The slow water flow shall extend the life span of wells.
1) A continuous slot opening which significantly increases the available open area, thus providing greater access to the water bearing zone.
2) A "V"shaped profile wire which avoids clogging and ensures an uninterrupted flow.
3) A uniform and efficient well development due to the continuous slot opening.
4) Ladder-like wire welded screens have a strong structure and high open area, as well as accurate slot dimension.
5) Ladder-like wire welded screens have the features of easy backwashing, last long, safety and reliability as well as low comprehensive cost.
