Description
Technical field
The utility model relates to pump technology field, particularly relates to a kind of axial-flow pump.
Background technique
During current axial-flow pump uses, normally motor via reducer is by power transmission to the pump housing, has following shortcoming:
Be connected by more piece drive link between speed reducer with the pump housing, more piece drive link is generally connected by inserting mode and is bolted, and the end of more piece drive link is cross structure, and in Long-Time Service process, yielding impact normally uses;
The fixed connection place of the transmission shaft of the pump housing is provided with a wearing piece, and wearing piece is tubular structure, is sleeved on pump housing transmission shaft surface, because wearing piece is an easily damaged parts, use a period of time just will change, Renewal process needs the pump housing and drive link to dismantle, waste time and energy, efficiency is low.
Summary of the invention
In order to solve deficiency of the prior art, the utility model provides a kind of axial-flow pump, its reasonable in design, and between drive link, Placement is firm not yielding, and wearing piece and fixed base are split-type structural, convenient disassembly, changes efficiency high.
The utility model solves the technological scheme that its technical problem adopts:
A kind of axial-flow pump, comprise ventilating water pipe, speed reducer, some drive links and the pump housing, described speed reducer and the pump housing are separately fixed on ventilating water pipe, connected by some drive links between speed reducer and the pump housing, it is characterized in that: all threadedly connect between described some drive links, the two ends of drive link are bolted to connection with the output shaft of speed reducer and the input shaft of the pump housing respectively, the input shaft of the described pump housing is fixed by the fixed base of a split-type structural, is connected between fixed base with input shaft by the wearing piece of a split-type structural.
Described fixed base is made up of the fixed bearing of two same structures, is provided with the cell body of the input shaft for the fixing pump housing inside two fixed bearings, is bolted to connection between two fixed bearings.
Described wearing piece entirety is tubular structure, and wearing piece is docked by two wear-resisting halfbody parts and forms.
Described some drive links are fixed respectively by bearing spider.
Described bearing spider is connected with described ventilating water pipe by support with bottom fixed base.
Some fixed supports are provided with bottom described ventilating water pipe.
The beneficial effects of the utility model are: reasonable in design, and between drive link, Placement is firm not yielding, can extend the working life of this device, and wearing piece and fixed base are split-type structural, convenient disassembly, change efficiency high.

In figure: 1 speed reducer, 2 pump housings, 3 drive links, 4 ventilating water pipes, 5 bearing spiders, 6 fixed bases, 7 wearing pieces, 11 wheel for inputting, 12 output shafts, 21 input shafts, 22 impellers, 41 fixed supports, 51 supports, 61 fixed bearings, 62 supports, 71 wear-resisting halfbody parts.
Embodiment
As Fig. 1, 2, 3, shown in 4: a kind of axial-flow pump, comprise ventilating water pipe 4, speed reducer 1, two drive links 3 and the pump housing 2, speed reducer 1 has a wheel for inputting be connected with motor 11 and for the output shaft 12 of Power output, the pump housing 2 inside is provided with impeller 22 and an input shaft 21, described speed reducer 1 and the pump housing 2 are separately fixed on ventilating water pipe 4, connected by two drive links 3 between speed reducer 1 and the pump housing 2, all threadedly connect between two described drive links 3, screwed tight direction between two drive links 3 is identical with the sense of rotation of the output shaft 12 of speed reducer 1, namely two drive links 3 ensure to stablize firm Placement in transmission process, the two ends of described drive link 3 are bolted to connection with the output shaft 12 of speed reducer 1 and the input shaft 21 of the pump housing 2 respectively,
The input shaft 21 of the described pump housing 2 is fixed by the fixed base 6 of a split-type structural, and be connected with described ventilating water pipe 4 by support 62 bottom fixed base 6, the wearing piece 7 being provided with a split-type structural between fixed base 6 with input shaft 21 is connected; Wherein said fixed base 6 is connected by the fixed bearing 61 of two same structures, is provided with the cell body of the input shaft 21 for the fixing pump housing 2 inside two fixed bearings 61, is bolted to connection between two fixed bearings 61; Described wearing piece 7 entirety is tubular structure, and wearing piece 7 is docked by two wear-resisting halfbody parts 71 and forms, and when wearing piece 7 needs to change, is taken apart by fixed bearing 61 and can change two wear-resisting halfbody parts 71.
Two described drive links 3 are fixed respectively by bearing spider 5, are connected bottom bearing spider 5 by support 51 with described ventilating water pipe 4.
Some fixed supports 41 are provided with, fixing and laying for ventilating water pipe 4 bottom described ventilating water pipe 4.
The foregoing is only preferred embodiments of the present utility model, as long as realize the purpose of this utility model technological scheme with basic same approach, all belong within protection domain of the present utility model.
