Making efficient, energy-efficient aeration type air blower is most important for sewage treatment plant, pharmaceutical factory and environment purification, beauty
Change the requirement at home.
The design of aeration type air blower and the pod in vapour compression machine structure is especially important.Current water conservancy diversion cover structure
Referring to Fig. 1, the cover including being in dome-type, the big end of cover is equipped with the stepped hole a for radially connected impeller, the small end of cover
It is hemisphere face equipped with the outer circle for the axial stepped hole b for connecting impeller, cover, for being oriented to gas, stepped hole a includes edge
The positioning section that axially sets gradually, resigning section, the diameter of stepped hole a positioning section are greater than the diameter of stepped hole a resigning section.However,
Current pod poor in processability, because in processing big end end face and the stepped hole a of cover need to be processed first, then
The hemisphere face and small end of cover can be processed using three-jaw support stepped hole hole a or folder cover big end outer circle.But it utilizes
When three-jaw supports stepped hole hole a, the wall thickness of stepped hole a positioning section is smaller, easily causes deformation, leads to part rejection, and utilizes three
The outer bowlder of claw clip cover, because cover outer circle is hemisphere face, three-jaw point contact similar with cover outer circle, clamping is unreliable, when processing
It easily causes part to change, tilt, it is also possible to part occur and fly out, lead to safety accident, in addition, the whole wall thickness of cover outer circle
It is smaller, it is easy to cause parts fixation to deform, causes part rejection.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of reliable aeration type air blower of clamping and steamings
Vapour compressor pod and its processing method.
The object of the present invention is achieved like this: a kind of aeration type air blower and vapour compression machine pod, including is in

Preferably, in step 2 and step 3, multiple gradients is taken to remove big surplus.
Preferably, in step 3, a technique lug is processed in the small end of cover, for grabbing cooperation clamping with three.
Preferably, in step 5, the cylindrical surface of cover big end outer circle is made to lean on the end face of flat three-jaw, centering cover big end
Outer circle, bounce are less than or equal to 0.01, and the end face of centering cover big end, bounce is less than or equal to 0.01.
By adopting the above-described technical solution, the invention has the following beneficial effects:
1. the outer circle of stepped hole a positioning section is in cylinder in aeration type air blower of the present invention and vapour compression machine pod
Type, the point contact before change between three-jaw and cover outer circle contact into line, improve clamping reliability；
2. the axial width of stepped hole a positioning section outer circle is greater than the axial width of stepped hole a positioning section inner wall in the present invention,
Its stress point is located at the thicker position of stepped hole a resigning section wall thickness when such clamping, caused by avoiding because of parts fixation deformation
Part rejection ensure that processing quality, improve clamping safety；
3. the processing method of aeration type air blower and vapour compression machine pod of the present invention, in step 2 and step 3
When removing big surplus using a gradient, because gradient is big, general three-jaw length is inadequate, needs to make a large amount of Special three-jaw,
It is preferred that taking multiple gradients to remove big surplus, and three-jaw can be straight in the small end of cover one technique lug of processing, such clamping
Folder technique lug is connect, a large amount of Special three-jaw of production is avoided, reduces costs；
4. the processing method of aeration type air blower and vapour compression machine pod of the present invention makes cover in step 5
The end face of flat three-jaw, the outer circle of centering cover big end are leaned in the cylindrical surface of big end outer circle, and bounce is less than or equal to 0.01, and centering cover is big
The end face at end, bounce are less than or equal to 0.01, eliminate because of stepped hole b caused by parts fixation tilts and stepped hole a concentricity
Overproof problem.
