Aokai well screens are manufactured by wedge shaped wire around an
internal array of longitudinal support rods. Each intersecting point of the wire
is fusion welded. The v or wedge shaped profile wire wraps around the
support rods over the full length of the screen creating a continuous slot
opening, hence the screen allows water (oil) to enter your well freely in
ample quantities while at the same time keeps the majority of sand and
gravel out of the well.
Advantage:
Continuous slot opening significantly increases the available open area,
providing greater access to the water-bearing zone. Non clogging V shaped
profile wire, avoiding clogging, is self-cleaning and ensures an uninterrupted
flow. Sand grains make only-two-point contact and do not wedge in the
screen's inwardly enlarging slot. Large open area allows more water to enter
at much lesser frictional head loss and the efficiency of well is improved
appreciably.
