| titleOfInvention | High flow sucker rod centralizer |
| abstract | The utility model discloses a high flow sucker rod centralizer which comprises a body and a centering body. The body is fixedly connected with the centering body. The body is provided with a through hole with the two ends communicated. The body is provided with overflowing holes which are communicated with the through hole. The body is a step shaft and comprises steps arranged at the two ends of the body and a diameter part arranged between the steps, the diameter part is provided with the centering body, and the centering body and the diameter part are connected to be a whole in a casting mode. Internal threads are both arranged both at the two ends of the body. The centering body is provided with a groove, and the groove is of a straight strip shape, or of a spiral shape or of an arc shape. The centering body is a nylon material centering body or a carbon fiber material centering body. The high flow sucker rod centralizer is high in strength and reasonable in structure, the centering body makes contact with an oil tube, abrasion of a sucker rod is prevented, so that the service life of the sucker rod is long, and due to the fact that the body is provided with the through hole and the overflowing holes in a machining mode, the overflowing area is large. |
