Anchor protection air deviated well pump
This pump was added tube outside the tubular pump, while operating can seal the lower end of liner, the oil and gas inside the well can flow through inlet tubing pup joint.
Features: Has strong ability to resist damage for up the assignments and John turnover
Use limit device or tubing anchor, all external force on the outer tube, pump barrel itself is not affected, to avoid the pump barrel distortion
When a fluid through a porous nipple and a small screen pump, flow direction change, liquid - gas more easily into the pump chamber, reduce the gas influence the pump work
A screen at the bottom of the barrel can make the settling sand and other foreign material in the tail pipe, not easily enter the pump cavity, which has a certain ability of sand control pump
In the seal on the mining technology, don't take the upper porous nipple, with screen on the tail pipe.
