Description

Polymer injection pump with novel sealing structure Technical Field The utility model relates to the field of polymer injection pumps, in particular to a polymer injection pump with a novel sealing structure. Background With the increase of the years of oil field development, underground crude oil is recovered for many years, the energy of an oil layer is continuously consumed, so that the pressure of the oil layer is continuously reduced, the yield of the oil well is reduced, a large amount of residual dead oil cannot be recovered, a means of injecting water into underground to wave to recover the crude oil from the energy of the stratum is generally adopted, namely, a large amount of water is injected into the underground, but the water content of the recovered crude oil reaches 90%. After oil-water separation, the oil-containing water is injected into the ground to prevent the pollution of the stratum surface. Such repeated injection and production increases the cost of production and the yield of produced oil decreases seriously. The polymer injection pump can meet the requirement of multiple exploitation of the oil field, and the polyacrylamide is injected into the ground, so that the polymer is used for driving the oil layer to move to the oil well for exploitation. Because the load of the injection pump is large, the pump pipe is extremely easy to damage, the service life is short, the replacement of the injection pump in the use process is troublesome, and the joint of the pump pipe is not provided with a sealing structure, so that the tightness of the joint of the injection pump and the pump pipe cannot be ensured. Disclosure of utility model The utility model aims to solve the defects in the prior art, and provides an injection pump with a novel sealing structure. In order to achieve the above purpose, the injection pump with the novel sealing structure comprises an injection pump body, wherein the front end of the injection pump body is fixedly connected with a pump outlet, the outer end of the pump outlet is provided with a pump connecting pipe, the outer ring of the tail end of the pump outlet is fixedly connected with a first connecting flange, the outer side of the first connecting flange is fixedly connected with a sealing ring, the outer ring of the inner end of the pump connecting pipe is fixedly connected with a second connecting flange, the outer side of the second connecting flange is provided with a sealing groove, springs which are uniformly distributed are fixedly connected in the sealing groove, the outer ends of the springs are fixedly connected with sealing rings, the upper end and the lower end of the first connecting flange and the second connecting flange are respectively provided with a mounting sleeve, the inner sides of the two mounting sleeves are respectively provided with a trapezoid groove, the two ends of the mounting sleeves are respectively fixedly connected with a connecting block, through hole is penetrated in the connecting block, and bolts are penetrated in the through hole. As a further description of the above technical solution: the sealing ring is arranged in the sealing groove, and the sealing ring is arranged outside the sealing ring. As a further description of the above technical solution: The sealing ring is arranged in the sealing groove. As a further description of the above technical solution: the inner wall of the trapezoid groove is in sliding connection with the outer walls of the first connecting flange and the second connecting flange.
