Abstract
The utility model relates to a water pump rotary shaft seal drainage structures, including a pump body, be provided with water inlet and delivery port on the pump body, still be provided with the passageway of installation pivot on the pump body, the bearing assembly that is used for articulated pivot sets gradually on the passageway, to the skeleton oil blanket of bearing assembly oil blanket, prevent that water from getting into bearing assembly's sealing member, be provided with the wash port on the tunnel side walls between sealing member and the skeleton oil blanket. This device simple structure, the leakproofness is good.
Description
Technical field
The utility model is related to a kind of water pump shaft lutation dewatering structure.
Background technology
Water pump high-speed rotation, once its sealing structure fails, current are position, meeting along where machine shaft into bearing
Bearing rust, service life of equipment is caused to shorten.
The content of the invention
The utility model makes improvement for the problem that above-mentioned prior art is present, i.e., skill to be solved in the utility model
Art problem is to provide a kind of water pump shaft lutation dewatering structure, simple structure, good airproof performance.
In order to solve the above-mentioned technical problem, a kind of technical scheme of the present utility model is：A kind of water pump shaft seals draining
Structure, including a pump housing, are provided with water inlet and delivery port on the pump housing, be additionally provided with the pump housing and install the logical of rotating shaft
Road, be disposed with the passage for be hinged rotating shaft bearing assembly, the outside framework oil seal to bearing assembly oil sealing, prevent water
Into the seal of bearing assembly, osculum is provided with the channel side wall between the seal and outside framework oil seal.
Compared with prior art, the utility model has the advantages that：Present apparatus simple structure, good airproof performance, no
Easily there is the accident of bearing water inlet.
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Brief description of the drawings
Fig. 1 is the organigram of the utility model embodiment.
Fig. 2 is the organigram of the utility model embodiment middle pump body.
In figure：The 1- pump housings, 11- water inlets, 12- delivery ports, 13- seals, 14- outside framework oil seals, 15- bearing assemblies, 16-
Passage, 2- motors, 3- rotating shafts, 4- osculums.
Specific embodiment
Embodiment one：As shown in Figure 1 and 2, a kind of water pump shaft lutation dewatering structure, including a pump housing 1, on the pump housing 1
Water inlet 11 and delivery port 12 are provided with, the passage for installing the rotating shaft 3 that rotation is ordered about by motor 2 is additionally provided with the pump housing
16, the bearing assembly 15, outside framework oil seal 14 to bearing assembly oil sealing, anti-for being hinged rotating shaft is disposed with the passage
Sealing enters the seal 13 of bearing assembly, and osculum 4 is provided with the channel side wall between the seal and outside framework oil seal.
In face of the rotating shaft of high-speed rotation, once seal is damaged, water enters along rotating shaft, and the oil sealing of bearing assembly is simultaneously not enough
To ensure that water does not enter in bearing assembly, inevitably result in bearing assembly and get rusty corrosion, and then influence the life-span of whole equipment, should
The design of osculum, when seal can be made to occur damaged, the water entered along rotating shaft is expelled directly out from the osculum, it is to avoid axle
The possibility that bearing assembly gets wet.
The foregoing is only preferred embodiment of the present utility model, it is all according to present utility model application the scope of the claims done it is equal
Deng change and modification, should all belong to covering scope of the present utility model.
