water well sand screen
|
Bridge slotted screen a type of well screen with vertical slots that are formed by protruding "bridges"that are pushed outward from the well casing.
The sand and gravel can not easily block the slot because of the special bridge design. It has great mechanical strength and water entering capacity.
Meanwhile, it use steel punching technology and rolled in many ways, so it is light, cheap and easily operating.
We use CNC to punch, so the slot can change as your requirements. In order to give customers more convenience, we can offer any diameter screens.
Cylinders are used as rotary screens, collectors such as screen laterals and nozzles, resin traps, in-line strainers, water intake screens, well screens, as well as many other applications involving liquid / solids separation.
1. A continuous slot opening which significantly increases the available open area, thus providing greater access to the water bearing zone.
2. A uniform and efficient well development due to the continuous slot opening.
3. Ladder-like wire welded screens have a strong structure and high open area, as well as accurate slot dimension.
4. Ladder-like wire welded screens have the features of easy backwashing, last long, safety and reliability as well as low comprehensive cost.
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 levels 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 groundwaters entering into the screen much slower than any other filtration apparatus, which will avoid sands entering into screen because of high pressure, thus reduce the abrasion of the pump.
