The invention discloses a double-triangular rotor pump, belongs to pumps and aims at providing an improvement structure of a gourd rotor pump. The double-triangular rotor pump is composed of a shell, a main rotor, an auxiliary rotor, a sealing ring, an arc-shaped sealing strip, sealing pieces and the like. The main rotor is arranged on a main shaft (19), and by means of transmission of a pair of gears (10), the auxiliary rotor (7) arranged on an auxiliary shaft (8) is engaged with the main rotor (13), the main rotor and the auxiliary rotor are arranged in the shell, a volume space is formed, and fluid is sucked in at one end and drained at the other end. Under the situation that the rotating speed ratio of the two rotors of the double-triangular rotor pump is 1 to 1, the main rotor formed by mutual enveloping of instantaneous center lines is large, and the auxiliary rotor formed by mutual enveloping of instantaneous center lines is small; the sealing problem of the rotor pump is solved through the method of the sealing pieces, the sealing ring and the arc-shaped sealing strip, as a result, the double-triangular rotor pump is similar to a screw pump or a compressor, but the size of the double-triangular rotor pump is smaller than that of the screw pump or the compressor, the machining cost of the double-triangular rotor pump is lower than that of the screw pump or the compressor, the service life of the double-triangular rotor pump is longer than that of the screw pump or the compressor, and the application range of the double-triangular rotor pump is wider than that of the screw pump or the compressor. The double-triangular rotor pump can retain the characters that a rotor pump is large in flow and small in size and can also approach the double beneficial effects that a piston pump has a good sealing effect.
Description
Technical field：The present invention relates 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, it is big from main rotor unlike lobe pump, it is secondary
Rotor is small, and in a housing for Pear-Shaped, its pulsation and noise is obtained for reduction to two rotors, operates very steady.
But interior leakage problem is serious, it is impossible to for the occasion of high pressure, and energy conversion efficiency is low, requirement on machining accuracy is highly difficult big, mill
It is shorter without the life-span in compensation use after damage, it and many impeller pumps：Can not picture as lobe pump, Gerotor pump, screw pump etc.
Piston pump has the sealing and wear-compensating of piston ring like that, Fluid pressure is reached higher degree, more long life, more
Use scope.
The content of the invention：For defect present in prior art, the present invention is intended to provide a kind of good sealing effect, fluid pressure
Power is high, and energy conversion efficiency is high, and machining accuracy difficulty is low, long service life, uses the wide double triangle impeller pump of scope.
To achieve these goals, the present invention uses following technical scheme：It includes that major-minor rotor is equilateral triangle, main to turn
Three sides of son are straight as far as possible, and three corner contours are circular arc, and the contour line of secondary rotor is with the contour line of main rotor
On the basis of form the mutual envelope of instantaneous Center, three sides of main rotor are inwardly recessed that radian is bigger, and the circumcircle of secondary rotor is bigger, main to turn
Three outwardly radians in side of son are bigger, and the circumcircle of secondary rotor is smaller.
On main shaft, secondary rotor passes through side plate by the axle at two ends to main rotor in housing together on countershaft
Support is held, two tops of axle make the secondary rotor on countershaft turn with main equipped with a pair of gear intermeshing transmissions in bonnet
Son coincide, and main rotor is 1 to 1 with the gearratio of secondary rotor, and main rotor first mate's rotor is small to make two in the case of rotating speed identical
The geometry of rotor constitute it is positive wait circular triangle, the diaphragm seal on main rotor and secondary rotor be provided with a step side and
Chute step side on rotor is engaged, and to limit diaphragm seal extension elongation, three primary seal pieces on two rotors are by shell fragment
Compression stretches out a tiny length（About 1 ~ 2 millimeter freely stretches）In the case of degree, to rotor and housing cavity wall and rotor with
The clearance seal of rotor, multiple secondary sealing pieces are compressed by shell fragment and all stretched out in the case of a tiny length between rotor and rotor
Gap is sealed, and the both sides of major-minor rotor are provided with sealing ring and are compressed by annular shell fragment, and arc sealing strip is compressed to both sides by arc spring lamination
Clearance seal, the shaft seal cover on main shaft fixes with housing, and in floating ring, compacting ring is by fluid in pump for O-ring
Floating ring and O-ring is set to be compacted between shaft seal cover and compacting ring under pressure effect.
Compared with the prior art, the present invention compared with pump with bottle gourd-shaped rotor by adopting the above-described technical solution, have essence
Difference, although the rotor of pump with bottle gourd-shaped rotor require that main rotor is big, and secondary rotor is small, but it is different with two rotating speeds of rotor
（The number of teeth is different）Constitute, its main rotor is double wedge, and secondary rotor is concave tooth, and secondary rotor and axle are an entirety, from axle
On draw out the clearance seal that a concave tooth for pit cannot solve the problems, such as to exist between rotor and rotor.And the off-axis heart of inscribed circle is too
Closely, that is, the depth of pit is less than bearing outside diameter, rotor must rotate two sides and just can inevitably leave one
Circumferential gap, the both bad processing of this method that pit is drawn on axle, and bad sealing, and transmission of the main rotor to secondary rotor
Or speedup, these be pump with bottle gourd-shaped rotor exist it is maximum the drawbacks of.Double triangle impeller pump is in two rotor speed 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 so that
Two rotors are all double wedges, and the high point of its circumcircle and the low spot of inscribed circle just meet what is sealed in aforementioned manners
Excellent condition, the sealing problem of impeller pump is solved using the method for diaphragm seal, sealing ring, arc sealing strip, impeller pump picture is lived
Plug pump reaches pump pressure higher like that, reduces machining accuracy and cost, improves energy conversion efficiency, increases the service life, its
Though as a result it is similar to screw pump or compressor, the volume than it is smaller, and the processing cost than it is lower, than its use longevity
Life it is longer, the scope of application than it is wider, moreover its two rotors can all be fabricated to it is hollow, if manufacture air compressor machine utilize this
It is individual it is hollow will have more a passage, be isolated in two passages so as to be easily done a lubrication liquid cooling fluid and compressed air
On, make the existing good cooling and lubricating of compressor, dry type air compressor machine can be made again, here it is being improved on the basis of pump with bottle gourd-shaped rotor
Meaning afterwards, it can retain rotor pump discharge large volume it is small the characteristics of, can like that have excellent sealing close to piston pump again
The double dominant of effect.
