Abstract
The utility model discloses an automobile water pump impeller with staggered leaves in the pump technique field, which includes an impeller hub with end fixedly connected with an impeller cover plate and integrated together, the impeller cover plate is rounded with vanes and a water way is formed between the adjacent vanes, wherein: the vanes have long vanes and short vanes that are staggered along the circular with symmetric distribution, the impeller profile of long vanes is double curvature arc, the export angle is forward bending line and the leave angle of the high end inside the vanes is acute angle; the impeller profile of short vanes is double curvature arc, the export angle is forward bending line and the leave angle of the high end inside the vanes is obtuse angle. Compared with the prior art, the water pump made from the automobile water impeller has high flowing, high lifting, high anti-cavitation of the vanes and high effectiveness, so as to meet the require of various high-power automobile motors.
Description
Technical field
The utility model belongs to the pump technical field, is specifically related to the staggered auto pump impeller of a kind of blade.
Background technique
Water pump is as the power unit that supplies water, be widely used in industry-by-industry, and as the cooling waterpump of motor car engine especially high-powered engine, to its performance such as flow, lift and reliability requirements are more and more higher, the employed water pump of the advanced type C121 high-powered engine of U.S. Caterpillar as Shanghai Diesel Engine Co., Ltd's introduction, this water pump has the impeller hub that the water pump spindle interference connects, form the impeller cover of one at the end face of impeller hub, blade is distributed on the impeller cover, and the molded lines of blade is made of single circular arc, and the molded lines outlet is back curved, the pump capacity that the impeller of this structure constitutes is little, lift is low, and efficient is low, the serious cavitation erosion of blade, influenced the cooling requirement that engine power increases, motor boils easily, causes part of damage, and power descends.
Summary of the invention
For addressing the above problem, the purpose of this utility model is to provide a kind of pump capacity big, the lift height, and blade anti-cavitation ability is strong, efficient height, the auto pump impeller that blade that can supporting different high-powered automobiles motors is staggered.
For achieving the above object, the technical solution of the utility model is: the staggered auto pump impeller of this blade has impeller hub, the end of the impeller hub impeller cover that is connected is an one, be surrounded with linear leaf and short blade on the impeller cover, linear leaf and short blade are symmetrically distributed along circumference is staggered, form water channel between the adjacent vanes, and the impeller profile of linear leaf is the double curvature circular arc, exit angle is antecurvature line, and the inboard high-end leaf angle of blade is an acute angle; The impeller profile of short blade is the double curvature circular arc, and exit angle is antecurvature formula, and the inboard high-end leaf angle of blade is the obtuse angle.
Adopt the beneficial effect of such scheme: be surrounded with linear leaf and short blade on the water pump vane cover plate, linear leaf and short blade are interspersed, and impeller profile is the double curvature circular arc, reduce the import excretion coefficient, reduce the hydraulic shock loss, improve the ability of water pump anti-cavitation, improve the working efficiency of water pump, prolonged the working life of water pump, export antecurvature raising delivery of pump and lift, this water pump gets a promotion the high-powered engine performance applicable to new working environments of model water pump such as C121, has satisfied user's requirement.
Below in conjunction with accompanying drawing specific embodiment of the utility model is done explanation in further detail.
Description of drawings
Fig. 1 is the plan view of the staggered auto pump impeller of the utility model blade.
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
The auto pump impeller that blade as shown in Figure 1 and Figure 2 is staggered, has impeller hub 1, the end of the impeller hub impeller cover 2 that is connected, impeller cover 2 forms one with impeller hub 1, on impeller cover 2 around a plurality of linear leafs 3 and short blade 4 are set, and staggered the symmetrical distribution, form water channel 5 between the adjacent deviated splitter vane, the impeller profile of linear leaf 3 is the circular arc that two different curvature form, the exit angle of linear leaf adopts antecurvature formula, the end that is blade shines to the impeller sense of rotation, and exit angle is greater than 90 °, and the inboard high-end leaf angle 6 of blade is an acute angle.The impeller profile of short blade 4 is the circular arc that two different curvature form, the short blade exit angle adopts antecurvature formula, exit angle is greater than 90 °, short blade 4 inboard high-end leaf angles 7 are the obtuse angle, compare with linear leaf, reduced the area of contour of blade, reduced the import excretion coefficient, reduced inlet velocity in inlet end.
Claims (1)
1, the staggered auto pump impeller of a kind of blade, has impeller hub, the end of the impeller hub impeller cover that is connected is an one, be surrounded with blade on the impeller cover, form water channel between the adjacent vanes, it is characterized in that: described blade is linear leaf and short blade, linear leaf and short blade are symmetrically distributed along circumference is staggered, the impeller profile of linear leaf is the double curvature circular arc, and exit angle is antecurvature line, and the inboard high-end leaf angle of blade is an acute angle; The impeller profile of short blade is the double curvature circular arc, and exit angle is antecurvature formula, and the inboard high-end leaf angle of blade is the obtuse angle.
