THBM Oil Well Pump Tubing Large Volume With Cup Anchor
40-375 Large Volume THBM THBC Model Tubing Pump:
Large volume tubing pump description:
In the rod - having pump operation, API standard subsurface sucker rod pump is one quite important downhole oil production equipment. which can be divided into tubing pump and rod pump.
operating principle of tubing pumps:The pump barrel assembly directly fixed on a tubing string. the plunger assembly connected on the sucker rod string ,and with the up and down reciprocating motion, so as to realize the production process. Its advantage lies in: in the process of oil production, when the traveling valve and fixed valve side problems arise,valve side can be proposed by the sucker rod, piston and extractor , don’t put the whole pump and tubing string out of the well, reduce the work intensity and the operation cost.
For some large production wells, larger bore of tubing pump can be worked if the on-off connector is installed. Tubing pump is the strongest pump. It has large flowing area for fluid and it is suitable for producing viscosity oil.
Stationary Heavy Wall, Tubing Pump, its standing valve can not be pulled out.
