Patented Gas Anchor
This patented gas anchor
also can solve the sand problem.
Installation: You need
connect two or more used tubing with a plug (for storage the sand) to the
bottom of the gas anchor. Then connect the top coupling to the bottom of
the tubing of the build-in rod pump
Principle:
1) First separation: up stroke brings both liquid and
gas into sand setting pipe, gas floats to the top. Down stroke makes gas
escape fro the upper part of the sand-setting pipe;
2) 2nd separation: the remaining gas enter
into Stage I spiral separation unit. Centrifugal effect makes liquid move
to the tubing wall and push to the Stage II spiral separation unit. The gas
escaped through center check valve I
3) 3rd separation: same principle as the 2nd
separation
4) First separation: up stroke brings both liquid and
gas into sand setting pipe, gas floats to the top. Down stroke makes gas
escape for the upper part of the sand-setting pipe;
5) 2nd separation: the remaining gas enter
into Stage I spiral separation unit. Centrifugal effect makes liquid move
to the tubing wall and push to the Stage II spiral separation unit. The gas
escaped through center check valve I
6) 3rd separation: same principle as the 2nd
separation
7) First separation: up stroke brings both liquid and
gas into sand setting pipe, gas floats to the top. Down stroke makes gas
escape for the upper part of the sand-setting pipe;
8) 2nd separation: the remaining gas enter
into Stage I spiral separation unit. Centrifugal effect makes liquid move
to the tubing wall and push to the Stage II spiral separation unit. The gas
escaped through center check valve I
9) 3rd separation: same principle as the 2nd
separation
