Description
Technical field：It the utility model is related to a kind of pump, more particularly to a kind of improved structure of pump with bottle gourd-shaped rotor.
Background technology：A kind of pump with bottle gourd-shaped rotor is devised in person within 2001, its main rotor unlike lobe pump is big, secondary
Rotor is small, and for two rotors in the housing of a Pear-Shaped, its pulsation and noise is obtained for reduction, and operating is very steady.
But interior leakage problem is serious, is not used to the occasion of high pressure, and energy conversion efficiency is low, requirement on machining accuracy is highly difficult big, mill
Shorter without the life-span in compensation use after damage, it is with many impeller pumps：Can not picture as lobe pump, Gerotor pump, screw pump etc.
Piston pump has piston ring to give to seal and compensate like that, pressure is reached higher level, the more long life, more uses model
Enclose.
The content of the invention：For defect present in prior art, the utility model aims to provide a kind of good sealing effect, stream
Body pressure is high, and energy conversion efficiency is high, and machining accuracy difficulty is low, service life length, the wide double triangle impeller pump of use range.
To achieve these goals, the utility model uses following technical scheme：It is small two including main rotor first mate's rotor
Rotor is all triangle, and three sides of main rotor are more straight than secondary rotor, and three angles are circular arc, and two rotors of major-minor are mutually rolling
Cut under rotation, the contour line of secondary rotor and the contour line of main rotor form the mutual envelope of instantaneous Center, and three sides of main rotor concave
Enter that radian is bigger, the circumcircle of secondary rotor is bigger, and three outwardly radians in side of main rotor are bigger, and the circumcircle of secondary rotor is got over
It is small.
For main rotor in housing on main shaft, secondary rotor passes through axle of the side plate by both ends together on countershaft
Hold support, the top of two axles makes the secondary rotor on countershaft turn with main equipped with a pair of gears intermeshing transmissions in bonnet
Son coincide, and the gearratio of main rotor and secondary rotor is 1 to 1, and the diaphragm seal on main rotor and secondary rotor is provided with a step
While with being engaged during the chute step on rotor, to limit diaphragm seal extension elongation, three primary seal pieces on two rotors by
Shell fragment ejects 1 ~ 2 millimeter of certain length, and rotor and the gap of housing cavity wall and main rotor and secondary rotor are sealed, more
Individual secondary sealing piece is sealed by shell fragment ejection certain length to the gap of main rotor and secondary rotor, and the both sides of major-minor rotor are provided with
Sealing ring is compressed by annular shell fragment, and arc sealing strip is compressed the clearance seal to both sides, the axle on main shaft by arc spring lamination
Capping is fixed with housing, and for O-ring in the floating ring, compacting ring is mounted in floating ring and O-ring side, the pressure work of fluid in pump
With on compacting ring, O-ring is compressed, play axle envelope use.
Compared with the prior art, the utility model compared with pump with bottle gourd-shaped rotor by adopting the above-described technical solution, have
Although this qualitative difference, the rotor of pump with bottle gourd-shaped rotor require that main rotor is big, secondary rotor is small, but it is with the rotating speed of two rotors
It is different（The number of teeth is different）Forming, its main rotor is double wedge, and secondary rotor is concave tooth, and rotor and axle are an entirety, from
The concave tooth of a pit is drawn out on axle can not solve the problems, such as existing clearance seal between rotor and rotor.And the off-axis heart of inscribed circle
Too closely, that is, the depth of pit is less than bearing outside diameter, and rotor, which must rotate two sides, just can inevitably leave one
Individual circumferential gap, the both bad processing of this method that pit is drawn on axle, and bad sealing, and main rotor is to the biography of secondary rotor
Dynamic or speedup, the drawbacks of these are maximum existing for pump with bottle gourd-shaped rotor.Double triangle impeller pump is in two rotor speeds 1 to 1
In the case of, with the mutual envelope of instantaneous Center（Contour line change on the basis of main rotor）The main rotor of composition is big, and secondary rotor is small, makes
It is all double wedge to obtain two rotors, and the high point of its circumcircle and the low spot of inscribed circle just meet and sealed in aforementioned manners
Excellent condition, using diaphragm seal, sealing ring, arc sealing strip method solve impeller pump sealing problem, make impeller pump picture
Piston pump reaches higher pump pressure like that, reduces machining accuracy and cost, improves energy conversion efficiency, increases the service life,
Though it is similar to screw pump or compressor for its result, smaller than its volume, the processing cost than it is lower, than its use
Life-span is longer, wider than its scope of application, moreover its two rotors can all be fabricated to it is hollow, if manufacture air compressor machine utilize
This is hollow will to have more a passage, and two passages are isolated in compressed air so as to be easily done a lubrication liquid cooling fluid
On, make the existing good cooling and lubricating of compressor, and can makes dry type air compressor machine, and here it is improved on the basis of pump with bottle gourd-shaped rotor
Meaning afterwards, it can retain the characteristics of rotor pump discharge large volume is small, and and can has excellent sealing like that close to piston pump
The double dominant of effect.
