Abstract
The utility model discloses a high-lift and high-efficiency water pump impeller which comprises a blade inlet edge (1), a middle section (2) and a blade outlet edge (4), wherein the middle section (2) is connected with the blade outlet edge (4) by a section of circular arc (5) in a smooth way; the radius R of the circular arc (5) is 5-7% of the external diameter of the impeller; and the blade outlet angle beta 2 is 90 degrees, and the wrapping angle Phi 2 of a blade is 90-120 degrees. Under the condition that the external diameter of the impeller is determined, the high-lift and high-efficiency water pump impeller can improve the pump lift by changing the design of blade profile, and realizes high efficiency.
Description
Technical field
The utility model relates to a kind of water pump vane, particularly relates to a kind of high-lift high efficiency water pump vane.
Background technique
Water pump is widely used in the every field of national economy, and power consumption accounts for 20%～25% of gross generation, is the highly energy-consuming product.Impeller is the heart of water pump, and whether performance parameter Zhao flow, lift and efficient that the design quality is directly connected to water pump meet the demands.The lift of water pump is by the outside diameter decision of impeller, and diameter is big, the lift height.For obtaining high-lift pump, take to strengthen the way of impeller outer circular diameter usually, but external diameter is big, the disc friction of impeller is big, causes pump efficiency low.In addition, in the same pump housing, impeller outer diameter add the restriction that receives pump housing cut water position greatly, can not strengthen arbitrarily, maximum value is arranged, therefore, the pump housing is in case determine that the raising of pump head just is restricted.
The model utility content
Technical problem to be solved in the utility model provides a kind of under the fixed situation of impeller outer diameter, the high and high efficiency high-lift high efficiency water pump vane of pump head.
For solving the problems of the technologies described above, the high-lift high efficiency water pump vane that the utility model provides, comprise entrance edge of blade, intermediate section and exit edge of blade, between described intermediate section and the exit edge of blade by one section smooth connection of circular arc, the radius of arc R of described circular arc is 5～7% of an impeller outer diameter, blade outlet angle β
2Be 90 °, subtended angle of blade φ
2It is 90 °～120 °.
Adopt the high-lift high efficiency water pump vane of technique scheme, because blade outlet angle β
220 °～30 ° by common impeller change 90 ° into, and pump head is improved, raising ratio about 15%.Simultaneously, entrance edge of blade is identical with the shape of common impeller with intermediate section, does not destroy flowing state.Though blade outlet angle β
2Can cause after becoming 90 ° that blade pitgh narrows down, increase hydraulic loss, but subtended angle of blade φ
2Have only about 90% of common impeller to be 90 °～120 °, both cancel out each other, and blade pitgh does not change, and therefore, the efficient of water pump can not descend.For the water pump vane of identical lift, because the impeller outer diameter of technique scheme is little, disc friction also can be little, so pump efficiency can be than the common impeller height of identical lift.
In sum, the utility model by changing the blade profile design, has improved pump head, and has realized high efficiency under the fixed situation of impeller outer diameter.
Description of drawings
Fig. 1 is common impeller blade shapes schematic representation;
Fig. 2 is the utility model impeller blade shapes schematic representation.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, common impeller blade comprises entrance edge of blade 1, intermediate section 2 and outlet limit 3, blade outlet angle β
1Be generally 20 °～30 °, subtended angle of blade φ
1Be generally 100 °～130 °.
Referring to Fig. 2, the utility model impeller blade comprises entrance edge of blade 1, intermediate section 2 and exit edge of blade 4, the entrance edge of blade 1 of entrance edge of blade 1 and intermediate section 2 and common impeller is identical with the shape of intermediate section 2, between intermediate section 2 and the exit edge of blade 4 by the 5 smooth connections of one section circular arc, the radius of arc R of circular arc 5 is 5～7% of an impeller outer diameter, blade outlet angle β
2Be 90 °, subtended angle of blade φ
2Be common impeller cornerite φ
190% promptly 90 °～120 °.
Because blade outlet angle β
220 °～30 ° by common impeller change 90 ° into, and pump head is improved, raising ratio about 15%.Simultaneously, the entrance edge of blade 1 of entrance edge of blade 1 and intermediate section 2 and common impeller is identical with the shape of intermediate section 2, does not destroy flowing state.Though blade outlet angle β
2Can cause after becoming 90 ° that blade pitgh narrows down, increase hydraulic loss, but subtended angle of blade φ
2Have only about 90% of common impeller to be 90 °～120 °, both cancel out each other, and blade pitgh does not change, and therefore, the efficient of water pump can not descend.For the water pump vane of identical lift, because the impeller outer diameter of technique scheme is little, disc friction also can be little, so pump efficiency can be than the common impeller height of identical lift.
The utility model by changing the blade profile design, has improved pump head, and has realized high efficiency under the fixed situation of impeller outer diameter.
Personnel in the present technique field should be realized that; the foregoing description is not with the qualification of the present utility model of opposing; as long as in the novel connotation scope of this reality, any the foregoing description technique variation, flexible program are not all exceeded protection domain of the present utility model.
Claims (1)
1. high-lift high efficiency water pump vane, comprise entrance edge of blade (1), intermediate section (2) and exit edge of blade (4), it is characterized in that: between described intermediate section (2) and the exit edge of blade (4) by the smooth connection of one section circular arc (5), the radius of arc R of described circular arc (5) is 5～7% of an impeller outer diameter, blade outlet angle β 2 is 90 °, and subtended angle of blade φ 2 is 90 °～120 °.
