Slips screw pump

The utility model provides a slips screw pump which is an oil extracting lifting device. The slips screw pump overcomes the defects that the current technical structure is complex, abrasion is large, energy consumption is high and cost is high. The slips screw pump is formed by connecting an upper connector, a static sealing ring, a movable sealing ring, a liquid drain pipe, a slips, an upper bearing, a pump cylinder, a rotor, a stator, a lower bearing and a lower connector. The upper portion of the screw pump cylinder is connected with the slips. The static sealing ring is arranged at the top of the screw pump cylinder. The oil pipe lower connector is arranged on the lower portion of the screw pump cylinder. The rotor is fixed to the middle in the screw pump cylinder through the upper bearing at the upper end and the lower bearing at the lower end. The liquid drain pipe is connected to the upper portion of the rotor. The screw pump stator is arranged at the middle end of the pump cylinder. A liquid inlet hole is formed in the liquid drain pipe. The movable sealing ring is arranged on the upper portion of the liquid drain pipe so as to seal an inner cavity of the screw pump. The upper connector is connected to the top of the liquid drain pipe.
