Abstract
The utility model provides an automobile engine water pump impeller comprising a metal impeller core and a plastic impeller body, wherein the metal impeller core is nested in the center of the plastic impeller body and is shaped like a circular tube, the plastic impeller body comprises an impeller disc which is provided with a circular base in the middle part, a plurality of blade bases for mounting blades are uniformly distributed at the outer edge of the circular base, the blade bases extend out of the edge of the circular base, each blade base is correspondingly provided with one of the blades, and the blades are S-shaped. The liquid is uniformly distributed in a space when the liquid is delivered and splashed out of the peripheries of the blades, so that the engine cooling effect is improved; the automobile engine water pump impeller can be widely applied to an automobile engine cooling system.
Description
Technical field
The utility model relates to a kind of water pump vane, particularly, relates to a kind of automobile motor water pump impeller.
Background technique
Water pump is the vitals of engine-cooling system, and its effect is pumping cooling liquid, makes cooling liquid rapid flow in the cooling water channel of motor, and the heat producing when taking away engine operation keeps engine work temperature.The water pump that motor car engine is used is Centrifugal water pump, and this water pump is comprised of housing, impeller, bearing, pump shaft, water seal and drive pulley etc.
Impeller is the core component of water pump, by motor driven rotary, make to produce vacuum in the middle of impeller, water will flow into toward vacuum place (on surface, being that impeller constantly sucks water), then water is discharged water by the impeller of High Rotation Speed again, plays one and pushes away influence of dynamic water.The mechanical energy of prime mover is directly passed to liquid, to increase static energy and the kinetic energy of liquid, mainly increase static energy.Therefore, impeller is the major influence factors of pump working efficiency, under specific operation, if Impeller Design is bad, will produce hydraulic loss and gap loss at pump entrance and blade place, existing plastic impeller is comprised of interior metal core wheel and outer plastic wheel body.Interior metal core wheel is formed by No. 20 seamless steel pipe manufacturing, and outer plastic wheel body is to be formed by common plastics manufacture.Impeller generally has 6～12 blades, and impeller has three kinds of open type, half-closed and encloseds.Unshrouded impeller without cover plate, is manufactured simple, easy to clean in blade both sides, is applicable to carry the material that contains relatively large suspended matter, and the fluid pressure of conveying is not high; Single shrouded wheel without cover plate, and has cover plate at opposite side in suction port one side, is applicable to the material of carrying easy precipitation or containing particle; Double shrouded wheel has front and rear cover plate at impeller in blade both sides, and efficiency is high, is applicable to carry clean liquid free from foreign meter.
Current impeller is when the liquid of carrying, and liquid directly flies out from the periphery space of blade, and the liquid that causes impeller to transfer out is inhomogeneous in space distribution, has reduced the cooling effect of motor.
Model utility content
The purpose of this utility model is to overcome the defect of above-mentioned prior art existence and a kind of automobile motor water pump impeller is provided, the utility model is when the liquid of carrying, when liquid flies out from the periphery of blade, the space distribution of liquid is even, has improved the cooling effect of motor.
The purpose of this utility model is achieved through the following technical solutions, a kind of automobile motor water pump impeller, comprise metal core wheel and plastics wheel body, described metal core wheel is nested in the center of described plastics wheel body, described metal core wheel is circular tube shaped, described plastics wheel body comprises wheel disc, the intermediate portion of described wheel disc is round base, outer rim at described round base is evenly equipped with a plurality of for the blade pedestal of blade is installed, described blade pedestal stretches out from the edge of described round base, on each blade pedestal, correspondence is provided with a blade, and described blade is rendered as S type.
Preferably, one end of the close described metal core wheel of described blade is rendered as acute angle, preferred, and described acute angle is 45 °.
Preferably, the number of described blade is 7.
Preferably, described plastics wheel body is phenolic resin wheel body.
Compared with prior art, the utlity model has following beneficial effect: the utility model when the liquid of carrying, because blade presents S type, has changed the direction that liquid directly flies out from the periphery of blade, be conducive to liquid and distribute towards space uniform, improved the cooling effect of motor.
