The quantity for stating groove is equal.
Preferably, three grooves are provided with the secondary rotor.
Preferably, the scraping blade includes the end face that can coordinate with the groove, and first positioned at the end face both sides
Side and second side；
The cross section of the groove is made up of the first end to end circular arc, the second circular arc and three-arc；Described first
The curvature of circular arc and three-arc is more than the curvature of the second circular arc；
In the rotary course of the main rotor and secondary rotor, the arc surface of the groove is entered from the end face of the scraping blade
Rise to the arc surface for leaving the groove and stop, the end face coordinates with the arc surface of the groove all the time.
Preferably, the first side and second side are arc surface.
Preferably, the curvature of the first circular arc and three-arc is equal.
Preferably, the first central angle of first circular arc is 84 ° -86 °；Second central angle of second circular arc is
22°-26°；3rd central angle of the three-arc is 84 ° -86 °.
Preferably, second central angle is equal to the 3rd central angle.
Preferably, first central angle is 24.48 °；Second central angle and the 3rd central angle are 85.58 °.
Preferably, the center of circle of first circular arc and three-arc respectively positioned at second circular arc two-end-point with it is described
On the line in the center of circle of the second circular arc.
Preferably, the curvature of the end face is more than the curvature of second circular arc.
The beneficial effects of the utility model are：The utility model flow is big, pressure is big, and makes pump during rotation,
Even if main rotor and secondary rotor shift, shock will not be also produced therebetween, so that the power loss of pump is small, used
Long lifespan, operating noise are small.

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
As shown in Figures 2 to 4, a kind of multiple blade displacement pump, including housing 1, main rotor is supported with by bearing in housing 1
3 and secondary rotor 4, three grooves 6 have been uniformly arranged on secondary rotor 4.
The scraping blade 5 that can coordinate with groove 6, the quantity of scraping blade 5 and the quantity of groove 6 are uniformly arranged on the circumference of main rotor 3
It is equal.
Scraping blade 5 includes the end face 5a that can coordinate with groove 6, and the first side 5b positioned at end face 5a both sides and the second side
Face 5c.First side 5b and second side 5c is arc surface.
As dotted line is distinguished in Fig. 5, the cross section of groove 6 is by the first end to end circular arc 6a, the second circular arc 6b and
Three-arc 6c is formed.In the course of work, scraping blade 5 enters groove from the first circular arc 6a first, after the second circular arc 6b, from the 3rd
Groove is left at circular arc 6c.
First circular arc 6a and three-arc 6c curvature is more than the second circular arc 6b curvature, the first circular arc 6a and three-arc
6c curvature is equal.The first circular arc 6a and three-arc 6c center of circle is located at the second circular arc 6b two-end-point and the second circular arc respectively
On the line in the 6b center of circle.
In the present embodiment, in the present embodiment, for submissiveer, the first circular arc 6a first center of circle that coordinates scraping blade and groove
Angle θ 1 and three-arc 6c the 3rd central angle θ 3 is 85.58 °, and the second circular arc 6b the second central angle θ 2 is 24.48 °,
In other embodiments, the other values between the first central angle θ 1 or 84 ° -86 °, the second central angle
Other values between θ 2 or 22 ° -26 °, the other values between the 3rd central angle θ 3 or 84 ° -86 °.
In the present embodiment, to make scraping blade preferably be combined with groove, particularly after scraping blade end wear, there is certain benefit
The effect of repaying, the curvature of the end face 5a are more than the second circular arc 6b curvature.
As shown in Fig. 4, Fig. 6 and Fig. 7, during volume pump work, in the rotary course of main rotor 3 and secondary rotor 4, from scraping blade
The arc surface that 5 end face 5a enters groove 6 stops to the arc surface for leaving groove 6, and arc surfaces of the end face 5a all the time with groove 6 is matched somebody with somebody
Close.In this course, water is delivered to delivery port from the water inlet of housing, realizes that pressure conveys.Due to the shape to scraping blade 5 and
The particular design of camber line in groove 6, so that the both sides of the edge position of the edge of scraping blade 5 and groove 6 will not produce position punching
It is prominent, hit so as to trigger.Compared to traditional displacement pump, due to adding the quantity of groove, and main rotor and secondary rotor collaboration work
Make, therefore a pump substantially improves 50% flow and pressure.
In the present embodiment, three scraping blades and three grooves are provided with, in other embodiments, three can also be set
Above-mentioned scraping blade and groove more than individual, to reach essentially identical technique effect.
Preferred embodiment of the present utility model described in detail above.It should be appreciated that the ordinary skill people of this area
