Connecing, the end of connecting rod 3 is connected with tubing pump 4.Concrete, high temperature direct current generator 1 is for providing for tubing pump 4
Driving force, ball-screw screw assembly 2 is then converted to the reciprocating action of tubing pump 4 for driving motor.
It should be noted that as it is shown in figure 1, tubing pump 4 farther included urceolus the 41st, lining the 42nd, plunger 43 with
And the construction unit such as the inlet valve 44 being connected with down-hole oil tube, wherein, sleeve outer surface be preferably set to smooth and with
Ring-band shape unloads sand furrow groove.
As one of the present utility model more preferred embodiment, oil-submersible electric tubing pump of the present utility model
Further have following structure: connecting rod periphery is additionally provided with adapter sleeve, is connected with stabilizer by adapter sleeve.Connect
Bar passes through push-and-pull adapter sleeve so that the arm of stability of stabilizer opens or tightens up thus reduce the work hidden danger of oil well pump.
A kind of oil-submersible electric tubing pump that the utility model provides, this device includes high temperature direct current generator, ball
Screw-nut assembly, connecting rod and tubing pump；Wherein, high temperature direct current generator is for providing moving needed for tubing pump
Power；Ball-screw screw assembly for being converted into the action of oil pump plunger piston straight reciprocating motion by the power that motor provides.Tool
The oil-submersible electric tubing pump having said structure eliminates the oil pumper being arranged on ground, thus has more compact knot
Structure.
The above, detailed description of the invention only of the present utility model, but protection domain of the present utility model does not limit to
In this, any those familiar with the art, in the technical scope that the utility model discloses, can readily occur in change
Or replace, all should cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should be with described power
The protection domain that profit requires is as the criterion.
