Abstract
The invention relates to a rotor of a Roots type vapor compressor, and belongs to the field of vapor compression. The rotor comprises a rotor body the cross section of which is 8-shaped, wherein the sealing surface of the rotor body is parallelly provided with grooves at a certain interval; the grooves are internally provided with sealed strips matched with the grooves, the bottom surfaces of the sealed strips are provided with small holes, one ends of filament winding springs are arranged in the small holes, and the other ends of the filament winding springs prop against the bottom surfaces of the grooves; and the sealed strips are protruded out of the surface of the rotor body, and an expansion clearance is preset between the rotor body and a shell. The Roots type vapor compressor provided by the invention has the advantages that a clamping phenomenon of the rotor and the shell is greatly reduced, a sealing effect is good, and an energy-saving effect is notable.
Description
Technical field
The present invention relates to a kind of roots-type both vapor compression machine rotor, belong to the both vapor compression field.
Background technique
Secondary steam is relatively low and can not be energy saving as the heat source of uniform temp solution due to temperature, and the method that often adopts in recent years mechanical compress is compressed the secondary steam of this low temperature once, again uses as thermal source after improving temperature.present main both vapor compression machinery has roots-type and centrifugal two kinds, and traditional roots-type vapour compression machine is directly to be applied mechanically by the air roots blower, do not make improvements, due to the roots blower rotor and shell gap precision higher, it is only the 0.2mm left and right, and that steam medium carries the heat running temperature is higher, often cause thermal expansion due to rotor the phenomenon that rotor and shell block to occur, affected the stable operation of equipment, thereby but the compressor that has is with the large sealing effect that affected of rotor and shell gap, increase power of motor for this reason, reduced energy-saving effect.
Summary of the invention
According to above deficiency of the prior art, technical problem to be solved by this invention is: a kind of roots-type both vapor compression machine rotor is provided, and the phenomenon that rotor and shell are blocked greatly reduces, good sealing effect, and energy-saving effect is remarkable.
Roots-type both vapor compression machine rotor of the present invention, comprise that the cross section is the rotor body of the figure of eight, on the sealing surface of described rotor body every the parallel groove that has of a determining deviation, the Stamping Steel Ribbon that is complementary with groove is installed in groove, Stamping Steel Ribbon has aperture on the bottom surface, and filament winding spring one end is arranged in aperture, and the other end is against on groove floor, make the outstanding rotor body of Stamping Steel Ribbon surperficial, default clearance for expansion between rotor body and housing.
The existence of Stamping Steel Ribbon has greatly reduced the area of contact between rotor body and housing, and then frictional force reduces greatly; Stamping Steel Ribbon has aperture on the bottom surface, filament winding spring one end is arranged in aperture, the other end is against on groove floor, makes the outstanding rotor body of Stamping Steel Ribbon surperficial, default clearance for expansion between rotor body and housing, when the rotor body expanded by heating, rotor body can not contact with housing, and what contact with housing is still Stamping Steel Ribbon, due to the elastic force effect of filament winding spring, the frictional force that increases between Stamping Steel Ribbon and housing is very little, so the phenomenon that Stamping Steel Ribbon and housing block can not occur.
Described groove is parallel to the axis of rotor body, and the spacing between adjacent two grooves is 1-10cm.
Described groove cross section is up-narrow and down-wide.
Described Stamping Steel Ribbon cross section is up-narrow and down-wide, and its bottom width degree guarantees that than the little 0.05mm of described groove bottom width Stamping Steel Ribbon can be free to slide in groove; The Stamping Steel Ribbon height is not more than groove height, makes Stamping Steel Ribbon can not affect the engagement of two rotor bodies; Stamping Steel Ribbon length is identical with groove length, has guaranteed sealing effect.
Described Stamping Steel Ribbon by C, H, F, Si are crosslinked is composited, this kind Stamping Steel Ribbon has self-lubricating property, has further reduced friction.
The beneficial effect that the present invention compared with prior art has is:
The existence of Stamping Steel Ribbon has greatly reduced the area of contact between rotor body and housing, makes the frictional force between rotor body and housing greatly reduce; Stamping Steel Ribbon has aperture on the bottom surface, filament winding spring one end is arranged in aperture, the other end is against on groove floor, make the outstanding rotor body of Stamping Steel Ribbon surperficial, elastic force effect due to the filament winding spring, the phenomenon that rotor and shell are blocked greatly reduces, and has improved sealing effect, and then has saved electric energy.

Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described further:
As shown in Figure 1-Figure 3, roots-type both vapor compression machine rotor of the present invention comprises that the cross section is the rotor body 4 of the figure of eight, on the sealing surface of rotor body 4 every the parallel groove 3 that has of a determining deviation, the Stamping Steel Ribbon 2 that is complementary with groove 3 is installed in groove 3, Stamping Steel Ribbon 2 by C, H, F, Si are crosslinked is composited, Stamping Steel Ribbon has aperture 5 on 2 bottom surfaces, filament winding spring 1 one ends are arranged in aperture 5, the other end is against on groove 3 bottom surfaces, make the outstanding rotor body of Stamping Steel Ribbon 24 surfaces, default clearance for expansion between rotor body 4 and housing.Described groove 3 is parallel to the axis of rotor body 4, and the spacing between two grooves 3 is 5cm.Described groove 3 cross sections and Stamping Steel Ribbon 2 cross sections are all up-narrow and down-wide, Stamping Steel Ribbon 2 bottom width degree are than the groove 3 little 0.05mm of bottom width, guarantee Stamping Steel Ribbon 2 higher than rotor body 4 surfaces, Stamping Steel Ribbon 2 highly is not more than groove 3 height, makes Stamping Steel Ribbon 2 can not affect the engagement of two rotor bodies; Stamping Steel Ribbon 2 length are identical with groove 3 length.
The described size of the present embodiment, become to be grouped into etc. is optimal case, and its value depending on concrete performance are as the criterion to realize beneficial effect.
