Abstract
Lobed rotor pump blade wheel structure, include the impeller of a pair of cooperation, each impeller includes the convex wing that two its center lines are in the setting of same straight line, the projection of two convex wings is in circular curve, the stage casing of two sections of circular curves and impeller is connected by the circular curve of indent, two sections of indent circular curves in same side are connected by the circular curve of one section of evagination, projected outline's curve negotiating of impeller multi-section circular arc connects to form smooth curve, 30 ° 45 ° are reversed clockwise with cam center relative to the top of impeller in the bottom of one of impeller, another wheel bottom reverses 30 ° 45 ° with impeller center counterclockwise relative to the top of cam, the periphery of two impeller convex wings in rotation process has the face contacted with lobed rotor pump pump chamber wall always.The utility model optimizes and pump chamber inner wall contact area increases the linear of existing impeller, and to not easily lead to damage in impeller, leakage is small, and fluctuation is small, and volumetric efficiency is high.
Description
Technical field
The utility model belongs to lobed rotor pump part device field, especially with a kind of lobed rotor pump blade wheel structure.
Background technology
Lobed rotor pump is a kind of positive displacement pump of rotation, and the property with positive discharge capacity, flow does not become with economy
Change, changes the volume of work by the relative motion between rotor and the pump housing.Lobed rotor pump synchronizes reverse turn by two
Rotor generates suction (vacuum degree) in rotary course in entrance, and rotor chamber is separated several small spaces by two rotors, to inhale
Enter the material to be conveyed, therefore the periphery wall of the rotor of two cooperations and two side are contacted with pump housing internal chamber wall always.However
Existing cam follower is in trilobal cross or the types of page four, the appearance of the formation of cam follower and the pump chamber cooperation of trilobal cross or the type of page four
Product chamber volume or less than normal, less than normal so as to cause the flow of drive, the larger medium of particle is easy to be stuck in pump chamber.In addition existing
Some trilobal crosses or the type cam followers of page four are contacted with pump chamber wall for line always in rotation process, for a long time using being easy to cause
Cam follower is worn.
Utility model content
For above-mentioned background technology there are the problem of, the utility model is intended to provide that a kind of drive rate-of flow is big, cam
The nonabradable lobed rotor pump blade wheel structure of rotor.
For this purpose, the utility model uses following technical scheme：Lobed rotor pump blade wheel structure, characterized in that including a pair
The impeller of cooperation, each impeller include the convex wing that two its center lines are in the setting of same straight line, the projection of two convex wings
In circular curve, the stage casing of two sections of circular curves and impeller is connected by the circular curve of indent, is in two sections of same side
Indent circular curve is connected by the circular curve of one section of evagination, and projected outline's curve negotiating of impeller multi-section circular arc connects shape
At smooth curve, the bottom of one of impeller reverses 30 ° -45 ° with cam center clockwise relative to the top of impeller, another
A wheel bottom reverses 30 ° -45 ° with impeller center counterclockwise relative to the top of cam, and two impellers are in rotation process convexity
The periphery of the wing has the face contacted with lobed rotor pump pump chamber wall always.
As supplement to above-mentioned technical proposal and perfect, the utility model further includes following technical characteristic.
The periphery of the impeller is fixedly connected with cladding layer of polyurethane.
It can reach following advantageous effect using the utility model：By the utility model by existing lobed rotor pump leaf
Wheel is arranged to the structure of two convex wings, and the impeller of the opposite trilobal cross and four blade profiles being arranged in same pump chamber has seal chamber
The medium of the advantage that volume is big, flow is big, larger particles diameter is easy by pump chamber, to be not easy to make the medium of bulky grain to inhale
It is attached on impeller or pump chamber inner wall.The utility model optimizes and pump chamber inner wall contact area the linear of existing impeller
Increase, to not easily lead to damage in impeller, leakage is small, and fluctuation is small, and volumetric efficiency is high.
Description of the drawings
Fig. 1 is the dimensional structure diagram of the utility model.
Fig. 2 is the main structure diagram of the utility model.
Specific implementation mode
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
As shown in Fig. 1~Fig. 2, the utility model includes the impeller 1 of a pair of of cooperation, each impeller 1 include two wherein
Heart line is in the convex wing 2 of same straight line setting, and the projection of two convex wings 2 is in circular curve, two sections of circular curves and impeller 1
Stage casing is connected by the circular curve of indent, and two sections of indent circular curves in same side are bent by the circular arc of one section of evagination
Line connects, and projected outline's curve negotiating of impeller 1 multi-section circular arc connects to form smooth curve, the bottom phase of one of impeller
30 ° -45 ° are reversed clockwise with cam center for the top of impeller, another wheel bottom relative to cam top with leaf
30 ° -45 ° of the torsion counterclockwise of wheel center, the periphery of two convex wings 2 in rotation process of impeller 1 have and lobed rotor pump 3 always
Pump chamber wall contact face.The periphery of impeller 1 is fixedly connected with cladding layer of polyurethane.
