Abstract
A kind of Drawing-Core guide-vane pump, including outer barrel, diffuser, impeller, axis and guide support are pumped, include guide vane in diffuser.All other than impeller maximum outside diameter, diffuser and outer barrel are directly connected to guide vane in the diffuser of pump for design.The maximum gauge of the guide support is less than the internal diameter of outer barrel and the maximum gauge more than impeller.The diffuser is more than the maximum gauge of impeller in the minimum diameter of the upper section of impeller.Rotor can be extracted out very easily and be safeguarded by the utility model, and Drawing-Core without extracting diffuser out, can be reduced the outer barrel diameter of existing Drawing-Core centrifugal pump and low-specific-speed diagonal pumps, be reduced product cost and pump house cost.
Description
Technical field
The utility model belongs to water pump technology, is related to being not required to when a kind of Drawing-Core guide-vane pump, especially core pulling
Extract the guide-vane pump diagonal pumps and guide-vane centrifugal pump of diffuser out.
Background technology
Guide-vane pumps the centrifugal pump and diagonal pumps for having guide-vane, also there is the axial-flow pump of guide-vane.Currently, such pump is generally adopted
With not pulled core structure（Fig. 1）Or use pulled core structure（Fig. 2）.Not Drawing-Core pump must hang out whole pump when safeguarding, dismantle dimension
Shield, is safeguarded cumbersome in this way.It Drawing-Core can pumping, pump takes out component in addition to entire rotor, further includes the diffuser in stator,
And diffuser is the larger part of quality in guide-vane pump, which substantially increases the weight that can take out component, and for centrifugal pump and
For the diagonal pumps of low-specific-speed, such pump diffuser outer rim is calabash shaped, and maximum external profile diameter is more much larger than impeller diameter,
Therefore it can take out that the barrel diameter of structure is very big, the manufacturing cost and floor space of water pump be increased, to increase pump house
Cost.Therefore this pump is seldom designed as Drawing-Core structure at present.
Utility model content
In order to overcome above-mentioned prior art can not pulled core structure guide-vane pump troublesome maintenance the shortcomings that and it is existing can be Drawing-Core
The shortcomings that pumping the pumping diffuser needed, the utility model are intended to provide a kind of Drawing-Core guide-vane pump, the pump in core pulling not
Need to extract diffuser out, have the advantages that it is existing it is Drawing-Core pump easy to maintain, while existing Drawing-Core centrifugal pump and low can be reduced
The outer barrel diameter of the diagonal pumps of specific speed reduces product cost and pump house cost.
The utility model solves technical solution used by its technical problem：
A kind of Drawing-Core guide-vane pump, including outer barrel, diffuser, impeller, axis and guide support are pumped, it is wrapped in diffuser
Contain guide vane.All other than impeller maximum outside diameter, diffuser and outer barrel are directly connected to guide vane in the diffuser of pump.
The maximum gauge of the guide support is less than the internal diameter of outer barrel and the maximum gauge more than impeller.
The diffuser is more than the maximum gauge of impeller in the minimum diameter of the upper section of impeller.
It is safeguarded the utility model has the beneficial effects that can very easily extract rotor out, and Drawing-Core without extraction
Diffuser, can reduce the core pulling barrel diameter of existing low-specific-speed diagonal pumps and centrifugal pump, reduce product cost and pump house at
This.
Description of the drawings
Fig. 1 is the guide-vane pump schematic diagram of existing not pulled core structure.
Fig. 2 is the guide-vane pump schematic diagram of existing pulled core structure.
Fig. 3 is the guide-vane pump schematic diagram of the pulled core structure of the utility model.
In figure：1. outer barrel, 2. diffusers, 3. guide vanes, 4. impellers, 5. axis, 6. guide supports.
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
A kind of Drawing-Core guide-vane pump, including pump outer barrel 1, diffuser 2, impeller 4, axis 5 and guide support 6, guide vane
It include guide vane 3 in body 2.All design is other than 4 maximum outside diameter of impeller for guide vane 3 in the diffuser 2 of pump, diffuser 2
It is directly connected to pump outer barrel 1.
The maximum gauge of guide support 6 is less than maximum gauge of the internal diameter more than impeller 4 of outer barrel 1.Diffuser is in impeller 4
Upper section minimum diameter, be more than impeller 4 maximum gauge.Guide support 6 in installation maintenance as can take out component with
Rotor part（Fastener including impeller 4 and axis 5 and above）It extracts out together, guide vane is stuck in after installation.
Claims (3)
1. a kind of Drawing-Core guide-vane pump, including outer barrel, diffuser, impeller, axis and guide support are pumped, include in diffuser
There is guide vane, it is characterized in that：For guide vane in the diffuser of pump all other than impeller maximum outside diameter, diffuser and outer barrel are straight
It connects in succession.
2. a kind of Drawing-Core guide-vane pump according to claim 1, it is characterized in that：The maximum of the guide support is straight
Diameter is less than the internal diameter of outer barrel and the maximum gauge more than impeller.
3. a kind of Drawing-Core guide-vane pump according to claim 1, it is characterized in that：The diffuser is in the upper of impeller
The minimum diameter of square part is more than the maximum gauge of impeller.
