Abstract
The utility model discloses a pump cover which comprises a pump cover body with a shaft hole. The pump cover body is provided with a sealing structure and a lubricating structure. The sealing structure comprises a sealing ring which is connected with the pump cover body by means of screwing. The lubricating structure comprises a screw plug and a lubricant passage communicated with the shaft hole. Since the sealing ring of the pump cover is connected with the pump cover body by means of screwing and less prone to looseness in operation, sealing effects can be truly guaranteed. Moreover, the lubricating structure enables lubricant to always exist at the joint of the pump cover and a shaft, and consequently contact abrasion between the shaft and the pump cover is avoided, and the service life of the pump cover is guaranteed.
Description
Technical field
The utility model relates to mechanical field, particularly a kind of pump cover.
Background technique
Oil hydraulic pump is to rely on the change of airtight swept volume to realize suction, press liquid, thereby mechanical energy is converted to the machine of hydraulic energy.Be the dynamical element of hydraulic system, its effect is the pressure energy that the mechanical energy of prime mover is converted to liquid.The factor in working life that affects oil hydraulic pump is a lot, except pump self design, manufacture factor also relevant with operation in the selecting of pump use relevant first (as coupling, oil purifier etc.), trial run and run engineering etc. with some.
The fault that oil hydraulic pump the most easily occurs is at present: when the sealing of pump cover seal ring, seal ring is easily loosening, causes leaking or leakage of oil, next is that axle passes pump cover axis hole, in rotation process, can have eccentric phenomena, cause the wearing and tearing of axle and pump cover, affect the working life of pump cover.
Model utility content
In view of this, the purpose of this utility model is to provide a kind of pump cover, makes its good sealing effect, long service life.
The utility model solves the problems of the technologies described above by following technological means: a kind of pump cover, comprise the pump cover body that is provided with axis hole, on described pump cover body, be provided with sealing configuration and lubricating structure, described sealing configuration comprises seal ring, described seal ring is connected with pump cover body by the mode of screw-driving, the lubricated fluid passage that described lubricating structure comprises plug and is communicated with axis hole.
Further, on described pump cover body, be provided with seal ring axially locating step.
Further, on described lubricated fluid passage, be provided with Lubricants accumulator tank.
Further, described lubricated fluid passage is four that are uniformly distributed circumferentially.
The beneficial effects of the utility model: pump cover of the present utility model, comprise the pump cover body that is provided with axis hole, on described pump cover body, be provided with sealing configuration and lubricating structure, described sealing configuration comprises seal ring, described seal ring is connected with pump cover body by the mode of screw-driving, the lubricated fluid passage that described lubricating structure comprises plug and is communicated with axis hole, the seal ring of this pump cover is connected with pump cover body by the mode of screw-driving, in working procedure, can not become flexible, can conscientiously ensure sealing effect, arranging of lubricating structure can make the joint of pump cover and axle have all the time Lubricants, avoid axle and pump cover contact wear, ensure the working life of pump cover.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is left view.
Embodiment
Below with reference to accompanying drawing, the utility model is elaborated, as depicted in figs. 1 and 2: this pump cover, comprise the pump cover body 1 that is provided with axis hole, on described pump cover body, be provided with sealing configuration and lubricating structure, described sealing configuration comprises seal ring 2, the mode that described seal ring is tightened by screw 3 is connected with pump cover body, the lubricated fluid passage 4 that described lubricating structure comprises plug 5 and is communicated with axis hole, the seal ring of this pump cover is connected with pump cover body by the mode of screw-driving, in working procedure, can not become flexible, can conscientiously ensure sealing effect, arranging of lubricating structure can make the joint of pump cover and axle have all the time Lubricants, avoid axle and pump cover contact wear, ensure the working life of pump cover.
As the further improvement to technique scheme, on described pump cover body, be provided with seal ring axially locating step.
As the further improvement to technique scheme, on described lubricated fluid passage, be provided with Lubricants accumulator tank 6, can ensure to be for a long time full of Lubricants on the surface of contact of pump cover and axle, not need often in lubricated fluid passage, to add Lubricants, can reduce the interpolation number of times of Lubricants.
As the further improvement to technique scheme, described lubricated fluid passage 4 is four of being uniformly distributed circumferentially, and Lubricants on the surface of contact of pump cover and axle is evenly distributed.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
