Abstract
The utility model relates to a sealing sleeve of a mud pump rod, which is made of rubber. The middle part of the sealing sleeve is provided with a corrugated pipe, and one end of the corrugated pipe is connected with an outer sealing interface of which the external diameter is provided with an annular recess, while the other end of the corrugated pipe is connected with an internal sealing interface which is provided with an isometric pipe. A sealing gasket is arranged inside the internal sealing interface, and a clamp is arranged outside the interface. The sealing sleeve has simple structure, and can follow moving elements to expand and contract so as to enhance the service life of sealing elements. The sealing sleeve thoroughly solves problem of drilling fluid infiltration, ensures the performance of lubricating oil, and prolongs the service life of a mud pump. Meantime, the wearing part of the sealing sleeve is convenient to replace, which enhances the availability ratio of the mud pump.
Description
The utility model relates to the oil drilling equipment annex, especially a kind of slush pump Jie rod seal cover.
Slush pump Jie rod seal apparatus structure complexity in the prior art, and the relative motion between sealing device and Jie's bar, rubber seal is is wherein very easily worn and torn, cause drilling fluid to enter the pump housing, mix with machine oil, destroy greasy property, quickened the wearing and tearing of moving component in the pump, thereby influenced the operate as normal and the application life of pump.
The purpose of this utility model is intended to propose a kind of seal and can stretches, and does not have slush pump Jie rod seal cover of relative motion with moving component, to overcome the deficiencies in the prior art part.
The purpose of this utility model can realize like this.
Slush pump Jie rod seal is applied mechanically elastomeric material and is made.At the middle part of sealing shroud is bellows, and an end of bellows is connected with the external seal of annular groove interface on the external diameter, and the other end of bellows such as is connected with at the interior sealed interface of caliber.And in interior sealed interface, be with a sealing lining ring, the external diameter of interface is provided with a clip.
Below in conjunction with embodiment and accompanying drawing, the utility model is described in detail.
Fig. 1 slush pump Jie rod seal cover schematic diagram.
The middle part of slush pump Jie rod seal cover is a bellows 2, and its tensile elongation satisfies the ultimate range of Jie's bar 7 motions.The external seal interface 1 of bellows is made integral body with bellows ringwise, and the groove on the interface is installed on the dividing plate 6 of the mud pump housing, and the interior sealed interface 3 of bellows is an isometrical pipe of thin-walled, also makes integral body with bellows.Be filled with sealing lining ring 4 between interface and Jie's bar, for guaranteeing to be connected firmly and good seal, fixing with clip 5 in the interface outside.
The utility model is simple in structure, does not have relative motion between seal and the moving component, can improve the application life of seal; Because application of the present utility model can thoroughly solve drilling fluid and infiltrate problem, can guarantee lubricants performance, prolongs the application life of slush pump, simultaneously, maintenance can be shortened greatly with the time of changing consumable accessory, thereby improved the utilization rate of slush pump.
