Description

Novel mechanical seal mud pump

Technical Field

The utility model relates to a slush pump technical field specifically is novel mechanical seal slush pump.

Background

The mud pump can be used for draining water, sucking and delivering excrement and thick liquid. The device is combined with high-pressure pumps, mud conveying pipes and other devices, is widely applied to large-scale projects such as dredging and damming of river channels, saves manpower and material resources, and strives for great economic benefits for society.

The mud pump plays a decisive role in the service life of the mud pump due to different media in the construction process. The currently adopted rubber sealing ring is sealed, silt easily penetrates through the sealing ring in silt media such as riverway dredging, then slurry and sand enter the bearing main shaft and the supporting cylinder body, the bearing main shaft is worn and damaged and cannot be used continuously, and therefore the service life is generally 20 days to three months (different media).

The technical problems reflected above are therefore a problem to be solved urgently by those skilled in the art.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a novel mechanical seal slush pump to solve the easy problem of wearing and tearing of slush pump in the husky medium of mud, with this abrasion resistance who improves the sealing member, prolong the life of slush pump, reduce the maintenance cost simultaneously.

In order to realize the purpose, the following technical scheme is adopted: novel mechanical seal mud pump, including main shaft and canned pump seat, the canned pump seat sets up between the support section of thick bamboo and the impeller of slush pump, the canned pump seat includes bearing, oil blanket, first apron, second apron, grease chamber tray and antifriction plate, bearing, oil blanket and first apron set gradually in the canned pump seat near one side of supporting a section of thick bamboo, grease chamber tray and antifriction plate set gradually in the canned pump seat near one side of impeller, the second apron sets up in one side that the antifriction plate was kept away from to the grease chamber tray, grease chamber tray inboard is provided with two-sided alloy mechanical seal, be provided with the third apron between grease chamber tray and the antifriction plate.

As an improvement, lubricating oil is injected into the oil chamber tray.

As an improvement, the oil chamber tray is provided with an oil filling hole.

Compared with the prior art, the utility model the advantage lie in: the scheme can effectively prevent mud and sand media from entering the sealing structure, avoids the bearing and the main shaft from being abraded, prolongs the service life of the mud pump from the original 20-three month days to three months to one year (different media), can be maintained on site, can replace one mechanical seal, does not need to lift the mud pump up for maintenance from the underwater of construction, and reduces the maintenance cost.

Drawings

Fig. 1 is a schematic structural diagram of the mechanical seal mud pump of the present invention.

Fig. 2 is a schematic structural diagram of the mechanical seal mud pump of the present invention.

As shown in the figure: 1. the double-faced alloy oil seal comprises a main shaft, 2, a support cylinder, 3, an impeller, 4, a bearing, 5, an oil seal, 6, a first cover plate, 7, a second cover plate, 8, an oil chamber tray, 9, an abrasion-resistant plate, 10, a double-faced alloy mechanical seal, 11, a third cover plate, 12 and an oil filling hole.

Detailed Description

Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", "vertical", "circumferential", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Combine attached figure 1-2, novel mechanical seal slush pump, including main shaft 1 and sealed pump seat, the sealed pump seat sets up between the support section of thick bamboo 2 and the impeller 3 of slush pump, the sealed pump seat includes bearing 4, oil blanket 5, first apron 6, second apron 7, grease chamber tray 8 and antifriction plate 9, bearing 4, oil blanket 5 and first apron 6 set gradually in the sealed pump seat and are close to one side of support section of thick bamboo 2, grease chamber tray 8 sets gradually one side that is close to impeller 3 in the sealed pump seat with antifriction plate 9, second apron 7 sets up in one side that antifriction plate 9 was kept away from to grease chamber tray 8, grease chamber tray 8 inboard is provided with two-sided alloy mechanical seal 10, be provided with third apron 11 between grease chamber tray 8 and the antifriction plate 9.
