Description
Technical field
The invention belongs to the cooling systems of automobile engine, and in particular to the water pump of automobile engine, in particular to
A kind of five jiaos of Water-pump impeller of automobile.
Background technique
Impeller is to pump the part for comparing core in class product, and blade portions are a more complicated curved-surface structures,
Whether the design of blade wheel structure meets hydrodynamic characteristic, influences the height of the working efficiency of water pump and the number of energy consumption,
Since prismatic blade design causes to be easy to produce reflux or whirlpool inside water pump, therefore auto pump is mostly arc shaped blade, arc at present
Blade ring is fixed on wheel disc around connector, easy to process, but cavitation-resistance is poor, and the service life of water pump blade is low, is needed
Often replacement blade.
Summary of the invention
The purpose of the present invention is improving the anti-cavitation performance and hydraulic efficiency of auto pump by setting blade construction, this
Invention provides a kind of five jiaos of Water-pump impeller of automobile.
The technical scheme is that a kind of five jiaos of Water-pump impeller of automobile, are arranged on hub disk including several
Impeller blade, the blade be it is irregular trapezoidal, the blade tilts 30 ° -60 ° from left to right, the blade
Left end is equipped with and cuts the water surface.
Further, the blade tilts 45 ° from left to right.
Further, the blade is arranged 5.
Further, the angle a of the blade lower end and horizontal plane is 10 °.
Further, the gradient for cutting the water surface is greater than the gradient of blade, cuts water area to increase.
The beneficial effects of the present invention are: this Water-pump impeller of automobile according to the flow of engine-cooling system and pressure demand into
Row design, determines after analyzing using CFD, by unique blade construction, improves the anti-cavitation performance and waterpower of auto pump
Efficiency.
Detailed description of the invention
Fig. 1 is overlooking structure diagram of the present invention；
Fig. 2 is invention schematic side view；
In figure: 1 is blade, and 2 be to cut the water surface.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Such as Fig. 1 and Fig. 2, the impeller blade on hub disk is arranged in including several for a kind of five jiaos of Water-pump impeller of automobile
1, the blade 1 be it is irregular trapezoidal, the blade 1 tilts 30 ° -60 ° from left to right, the left end of the blade 1
Equipped with cutting the water surface 2.
The blade 1 tilts 45 ° from left to right.
The blade 1 is arranged 5.
The angle a of 1 lower end of blade and horizontal plane is 10 °.
The gradient for cutting the water surface 2 is greater than the gradient of blade 1, cuts water area to increase.
Cavitation principle: when pressure for vaporization at a temperature of the absolute pressure for pumping liquid drops at that time, liquid is at this
Start wild flower and generates steam formation bubble, when this bubble reaches at high pressure, bubble pressure-rupturable, liquid matter while rupture
Point will occur mutually to hit and form water attack with high speed impact filling hole.Thus obtaining prevents pump cavitation from occurring most
Whole condition is the pressure for vaporization of the coolant liquid at a temperature of pump intake pressure is greater than at that time, by formula Q=AV, PV=
NRTA/Q obtains P=nRTA/Q, and wherein P is the pressure at import of water pump impeller end, and n is the amount of substance, and R is mol gas constant,
T is open type temperature, and A is the area of 1 input end of blade, and Q is flow, and the area on the inclined-plane 4 of 1 input end of blade processing is greater than original
The area of 1 input end end of blade, i.e. the area A of 1 input end of blade increase, in this way in the feelings for keeping the original performance of water pump constant
Under condition, so that the pressure P at import of water pump impeller end increases, to improve water pump anti-cavitation performance.
This Water-pump impeller of automobile the configuration of the present invention is simple, it is low in cost.According to the flow and pressure of engine-cooling system
Demand is designed, and is determined after analyzing using CFD, by unique blade construction, is improved the anti-cavitation performance of auto pump
And hydraulic efficiency.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention, for this field skill
For art personnel, it is clear that invention is not limited to the details of the above exemplary embodiments, and without departing substantially from spirit of the invention or
