Abstract
The present invention relates to a kind of roots-type both vapor compression machine rotor, belong to both vapor compression field, comprise that cross section is the rotor body of the figure of eight, the every parallel groove that has across a certain distance on the sealing surface of described rotor body, is provided with the sealing strip matching with groove in groove, sealing strip has aperture on bottom surface, filament winding spring one end is arranged in aperture, the other end is against in groove floor, makes the outstanding rotor body of sealing strip surface, default expansion clearance between rotor body and housing. The phenomenon that the present invention blocks rotor and shell greatly reduces, good sealing effect, and energy-saving effect is remarkable.
Description
Technical field
The present invention relates to a kind of roots-type both vapor compression machine rotor, belong to both vapor compression field.
Background technology
Indirect steam is relatively low and can not serve as the heat source of uniform temp solution due to temperature, is to save the energy, in recent yearsOften adopt the method for mechanical compress that the indirect steam of this low temperature is compressed, after raising temperature, again use as thermal source.Current main both vapor compression machinery has roots-type and centrifugal two kinds, and traditional roots-type vapour compression machine is by air sieveThatch blower fan is directly applied mechanically, do not make improvements, due to roots blower rotor and shell gap precision higher, be only 0.2mmLeft and right, and that steam medium carries heat running temperature is higher, often causes because rotor and shell appear in the thermal expansion of rotorThe phenomenon of blocking, has affected the stable operation of equipment, but thereby the compressor having by rotor and shell gap is large has affectedSealing effectiveness increases power of motor for this reason, has 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 vapour pressure is providedContracting machine rotor, the phenomenon that rotor and shell are blocked greatly reduces, good sealing effect, energy-saving effect is remarkable.
Roots-type both vapor compression machine rotor of the present invention, comprises that cross section is the rotor body of the figure of eight, and described rotor originallyThe every parallel groove that has across a certain distance on the sealing surface of body, is provided with the sealing strip matching with groove, at the bottom of sealing strip in grooveOn face, have aperture, filament winding spring one end is arranged in aperture, and the other end is against in groove floor, makes the outstanding rotor of sealing strip originallySurface, default expansion clearance between rotor body and housing.
The existence of sealing strip has greatly reduced the contact area between rotor body and housing, and then frictional force reduces greatly; SealingBar has aperture on bottom surface, and filament winding spring one end is arranged in aperture, and the other end is against in groove floor, sealing strip is given prominence to and turnedSub-body surface, default expansion clearance between rotor body and housing, in the time of rotor body expanded by heating, rotor body can be withHousing contact, what contact with housing is still sealing strip, due to the elastic force effect of filament winding spring, between sealing strip and housing, increasesFrictional force very little, so the phenomenon that there will not be sealing strip and housing to block.
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 sealing strip cross section is up-narrow and down-wide, and its bottom width degree is than the described little 0.05mm of groove bottom width, guarantees that sealing strip can beIn groove, be free to slide; Sealing strip height is not more than groove height, makes sealing strip can not affect the engagement of two rotor bodies; SealingBar length is identical with groove length, has ensured sealing effectiveness.
Described sealing strip is cross-linked and is composited by C, H, F, Si, and this kind of sealing strip has self-lubricating property, further reducesFriction.
The beneficial effect that the present invention compared with prior art had is:
The existence of sealing strip has greatly reduced the contact area between rotor body and housing, makes between rotor body and housingFrictional force greatly reduce; Sealing strip has aperture on bottom surface, and filament winding spring one end is arranged in aperture, and the other end is against recessedIn groove bottom, make the outstanding rotor body of sealing strip surface, due to the elastic force effect of filament winding spring, rotor and shell are blockedPhenomenon greatly reduces, and has improved sealing effectiveness, and then has saved electric energy.

Detailed description of the invention
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 cross section is the rotor basis of the figure of eightBody 4, the every parallel groove 3 that has across a certain distance on the sealing surface of rotor body 4, is provided with in groove 3 with groove 3 and matchesSealing strip 2, sealing strip 2 is composited by C, H, F, Si are crosslinked, sealing strip has aperture 5 on 2 bottom surfaces, filament winding spring1 one end is arranged in aperture 5, and the other end is against on groove 3 bottom surfaces, makes sealing strip 2 outstanding rotor body 4 surfaces, rotorDefault expansion clearance between body 4 and housing. Described groove 3 is parallel to the axis of rotor body 4, between two grooves 3Spacing is 5cm. Described groove 3 cross sections and sealing strip 2 cross sections are all up-narrow and down-wide, and sealing strip 2 bottom width degree are than 3 ends of grooveWide little 0.05mm, guarantees that sealing strip 2 is higher than rotor body 4 surfaces, and sealing strip 2 is highly not more than groove 3 height, makes sealingBar 2 can not affect the engagement of two rotor bodies; Sealing strip 2 length are identical with groove 3 length.
Size described in the present embodiment, become to be grouped into etc. is optimal case, and its value is depending on concrete performance, with realityExisting beneficial effect is as the criterion.
