Description
Technical field
The present invention relates to centrifugal vapor compressor field, particularly relate to a kind of manufacture method of centrifugal vapor compressor diffuser.
Background technology
Centrifugal vapor compressor is the energy re-using the indirect steam that it self produces, thus reduces a power-saving technology of energy demand to external world.Centrifugal vapor compressor is heat recovery system improves steam pressure by compression key equipment to the live steam produced.Its operation principle is: compression impellor rotates on the axle of compressor, and the gas entering compression impellor by with rotation, then enters in diffuser, by pressure that the speed-shifting of gas is required in diffuser.In recent years, along with economize energy is more and more paid attention to, centrifugal vapor compressor is more widely used.
Centrifugal vapor compressor is made up of rotor and stator two parts.Rotor is made up of parts such as impeller, main shaft, balancing frame, thrust discs, and stator is made up of parts such as diffuser, bend, return channel, spiral cases.The function of diffuser is mainly converted into pressure energy effectively from the impeller air-flow with larger kinetic energy out.So the quality of diffuser workmanship directly affects the height of the pressure energy of conversion.
Existing diffuser manufacture method due to blade place milling surplus a lot, after disposable milling blade, diffuser distortion is comparatively large, and the vane type line profile tolerance after machining is poor; Face deformation causes the perpendicularity between diffuser end face and locating hole poor simultaneously; In addition, existing diffuser manufacture method owing to processing whole connecting hole before half finish turning and finish turning end face, when subsequent turning end face because be interrupted cut, each amount of feeding and bite are all less, working (machining) efficiency is slow, and the vibrations of tool wear and lathe are comparatively large, affect the precision of lathe.
Summary of the invention
For in prior art, the vane type line profile tolerance of diffuser is poor, the technical problem of the perpendicularity difference between end face and locating hole; Further, for first processing reface end face after connecting hole in prior art, interrupted cut causes that efficiency is low, tool wear is large and affect the technical problem of lathe precision, the invention provides a kind of manufacture method of centrifugal vapor compressor diffuser, by rough milling blade passage, remove large surplus, then half finish-milling, last finish-milling blade passage again, reduce the deflection of diffuser after milling blade, avoid the impact on subsequent handling, improve the vane type line profile tolerance of diffuser and the perpendicularity between end face and locating hole; In addition, before half finish turning and finish turning end face, only machined end face two locating holes, improve working (machining) efficiency when half finish turning and finish turning end face, reduce the wearing and tearing to cutter.
To achieve these goals, technical scheme of the present invention is:

H. after the assay was approved, stroke boring center line on the end face and first step end face of large end and small end;
I. centering center line, drilling and tapping;
J. the end face of the large end of finish turning diffuser and endoporus;
K. file is repaiied bottom blade passage;
L. penetrating inspection is carried out to blade.
Further, in step b, four paws folder small end cylindrical, centering, the end face of the large end of rough turn diffuser, cylindrical, endoporus and second step end face.
Further, in step c, four paws folder holds cylindrical greatly, and by putting down end face greatly, centering is the large end endoporus of car, the end face of rough turn diffuser small end, cylindrical, endoporus and first step end face.
Further, in step e, soft three-jaw folder holds cylindrical greatly, and by putting down end face greatly, centering is the large end endoporus of car, the end face of half finish turning diffuser small end, cylindrical, endoporus and first step end face.
Further, in step f, soft three-jaw folder small end cylindrical, by flat first step end face, the large end endoporus of centering, jerk value is less than or equal to 0.015mm, the end face of the large end of half finish turning diffuser, cylindrical, endoporus and second step end face.
Further, in step I, large end end face is downward, and centering center line is pressed figure holes drilled through, small end end face is bored stepped hole on the first step end face of large end; Turn-over, centering center line, large end end face bores tapping female bore by figure.
Further, in step j, soft three-jaw folder small end cylindrical, by flat first step end face, centering is the large end endoporus of car, and jerk value is less than or equal to 0.015mm, the large end end face of finish turning diffuser.
Advantageous Effects of the present invention is:
1, blade milling be divided into rough mill, finish-milling processing, large surplus is removed when rough milling, and then finish-milling blade, solve the technical problem that in prior art, disposable milling surplus causes more greatly diffuser to be out of shape, reduce the impact of the deflection after blade milling on subsequent handling, improve the molded line profile tolerance of diffuser vane and the perpendicularity between end face and locating hole;
2, owing to only machined end face edge two locating holes before half finish turning diffuser end face, be continuous cutting when half finish turning end face, each amount of feeding and bite are comparatively large, improve working (machining) efficiency, reduce the wearing and tearing to cutter and the damage to lathe;
3, by the large end end face of finish turning diffuser, the local deformation near because of the large end end face aperture that causes of holing is eliminated.
