Bridge Slotted Screen
|
Bridge slotted water well screens, 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 cannot 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.
The Bridge Slotted Screen is used throughout the world for water, oil, and gas wells, and for environmental well completions. It is the dominant screen type used in the water well industry.
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.
