Abstract
The utility model belongs to an oil pump, more particularly relates to a rotation plunger oil pump which comprises an oil pumping rod, a pump cylinder, a rotary joint, a rotary dynamic joint and a plunger. The rotation plunger oil pump is characterized in that the rotary joint is internally provided with a pressure bearing and a rotary piece, the upper part of the rotary joint is in threaded connection with the pumping rod, the lower part of the rotary joint is in threaded connection with the upper part of the rotary dynamic joint, a spiral groove is arranged on the outer surface of the rotary dynamic joint, and the lower part of the rotary dynamic joint is in threaded connection with the plunger. The utility model has the advantages that the service life of the oil pump for a severely sanding production well can be greatly prolonged, and accumulated sands between the plunger and the pump cylinder are eliminated.
Description
Technical field
The utility model belongs to a kind of oil well pump, particularly a kind of rotation plunger oil-well pump.
Background technique
At present, in oil pumping process since oil viscosity big, contain sand etc. and make oil pump plunger piston and pump barrel produce uneven wear, even occur gluing together or the holddown phenomenon, have problems such as working life of pump is low.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides a kind of rotation plunger oil-well pump, this oil well pump rotating power joint outer surface has spiral chute, the axis of the relative top of spiral chute plunger has a spiral angle, during down stroke, the spiral fluted crude oil of flowing through generates the torque that plunger is intermittently rotated relative to pump barrel to the horizontal component velocity of plunger generation, thereby make pump barrel and plunger uniform wear, prolong the working life of pump.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of rotation plunger oil-well pump, form by sucker rod, pump barrel, swivel joint, rotating power joint and plunger, its special way is: pressure bearing and revolving part are arranged in the swivel joint, the top of swivel joint is threaded with sucker rod, the bottom of swivel joint is threaded with the top of rotating power joint, rotating power joint outer surface has spiral chute, and rotating power joint bottom is connected with plunger screw.
The beneficial effects of the utility model are: can prolong the working life of serious sand output well rod pump significantly, eliminate the long-pending sand between plunger and pump barrel.
