Disclosure of Invention
In order to overcome the defects, the utility model aims to provide a novel hydraulic double-acting rodless oil extraction pump breaker.
In order to achieve the above purpose, the hydraulic double-acting rodless oil extraction pump breaker of the utility model comprises a breaker body;
A working cavity of a working shaft is arranged in the partition body; two sections of sealing components are symmetrically distributed in the working cavity; the sealing assembly comprises a sand scraping assembly, a sealing section and a plug seal which are sequentially arranged from outside to inside.
Further, the sand scraping assembly consists of a compression nut and a sand scraping ring.
Further, a partition sealing gland is arranged between the sand scraping assembly and the sealing section.
Further, a lubrication channel is arranged on the breaker body between the two sections of sealing assemblies.
Further, the sealing section consists of a plurality of split metal sealing rings which are arranged continuously, and the split metal sealing rings are arranged in an annular mode by two or three arc-shaped metal pieces with the same radian; the outer circumferential surface of each arc-shaped metal piece is internally provided with a U-shaped groove; an O-shaped sealing ring is arranged in the U-shaped groove.
The partition device adopts a split type (compensating opening type) sealing ring (the material is wear-resistant, high-temperature-resistant metal and polymer nonmetal), the O-shaped ring is used for pre-pressure energy storage, and the holding force compensation is provided for the opening type sealing ring, so that the opening type compensating sealing ring is in a good holding and sealing state for a long time; adding a pan plug seal as a base pad bottom seal; the pressure compensation sand scraping device is added to scrape off impurities on the surface of the shaft, so that the sealing cavity has a relative working environment. The sealing performance is improved on the whole, and the service life of the partition is prolonged.

Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
In the description of the present invention, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate orientations or positional relationships based on the orientation or positional relationships shown in the drawings, merely to facilitate describing the present invention and simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present invention.
The terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present invention, unless otherwise indicated, the meaning of "a plurality" is two or more.
In the description of the present invention, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
As shown in fig. 1 to 3, a hydraulic double-acting rodless oil production pump breaker according to a preferred embodiment of the present utility model is schematically shown. Comprising the following steps: a breaker body; the hydraulic compensation sand scraping assembly presses the compression nut 2; the sand scraping ring 3 plays roles in scraping sand and auxiliary sealing, and a sand scraping ring backing plate 4; the sealing gland 5 is cut off to play a role of fixing a sealing element; the split metal sealing ring 6 (compensation type split sealing ring) is formed by two semicircular arc-shaped metal pieces 11 in an annular arrangement, and a space of 0.5-1.5 mm is arranged between every two adjacent arc-shaped metal pieces; a U-shaped groove is arranged on the outer circumferential surface of each arc-shaped metal piece; an O-shaped ring 7 is arranged in the U-shaped groove to seal the outer wall and store the pre-pressure, so as to give the internal holding force of the split metal sealing ring 6; a sealing element spacer 8, a flood plug baffle 9 and a flood plug 10, which play a sealing role on a reciprocating shaft; the lubricating liquid channel 11 is connected with backwater, so that lubrication and cooling effects are prevented when the unit runs idle, and loss caused by heat generated by idle friction is avoided.
The present invention has been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present invention.
