Oil-well pumping connection separator

Abstract

The utility model relates to an oil pump connection separator. The release track is provided with a track, the release track is connected with the upper part of the pump cylinder of the oil well pump, the sucker rod joint is connected with the upper part of the upper body, the spring and the sliding rail are installed in the upper body, and the head of the lower body is an ellipsoid. The lower interior of the upper body is an elliptical cavity. After the upper part of the lower body is inserted into the upper body, the elliptical cavities of the connected ellipsoids intersect, and the ellipsoid and the elliptical cavity overlap when separated. The orbits of the outer surfaces of the upper body and the lower body pass through the release orbit. The upper body and the lower body can produce relative rotation, so that the elliptical cavity of the upper body and the elliptical body of the lower body head are coincident. There is only one lower body, no relative moving parts, and there is no problem of sand burial and debris stuck, so the work is reliable. Under the diameter, the metal area of ​​the upper body and the lower body is the largest, so the strength is high, and the connection and separation are realized by lowering and lifting, and no other operations are required. Therefore, the connection and separation are convenient and the operation is simple.

Description

Technical field: [0001] The invention relates to a component used in oil extraction equipment in an oil field, and is a pump connection separator. Background technique: [0002] When the piston diameter of the oil well pump on the oil field is larger than the inner diameter of the oil pipe on the pump, a connecting separator is required to realize the connection and separation of the sucker rod and the oil well pump piston. There are many types of connection separators, but they all have some shortcomings. Although some can improve the carrying capacity and working life, the structure is complicated, the processing cost is high, and the connection and separation are not flexible. Some of the lower body connected to the oil well pump piston has moving parts, which are easily trapped by sand and debris and cannot slide, resulting in unsuccessful docking. Summary of the invention: [0003] The purpose of the present invention is to provide a pump connection separator that is reliab...
