A kind of electronic water pump impeller
Technical field
The utility model is related to electronic water pump technical field, more particularly to a kind of electronic water pump impeller.
Background technology
Electronic water pump is to make power set (abandoning motor drive mode completely) with using piezoelectric, from control to drive
It is dynamic thoroughly to realize electronization, control liquid to transmit completely with electronic integration system, so as to realize the adjustability of liquid transmission, precisely
Property.
Impeller is the heart of electronic water pump, and the quality of its performance directly affects the efficiency of centrifugal pump.Existing electronic water pump
The outstanding problem of presence is inefficient, consumed energy greatly.Wherein, centrifugal pump impeller is made up of wheel seat and wheel shaft, around wheel seat
The impeller of cloth individual layer spiral shape water dumping blade composition, the single layer blade is generally linear blade, arc line shaped blade or oblique line shape
Blade, these blades function only as centrifugation water dumping effect, and pressure is low, exhaust outlet is poor, and the angle of water dumping blade sets inadequate
Rationally, therefore pump efficiency is not high, energy consumption is big.
Utility model content
The technical problems to be solved in the utility model is:Not high in order to solve pump efficiency in the prior art, energy consumption is big
Technical problem, the utility model provides a kind of electronic water pump impeller.
The utility model solves the technical scheme that its technical problem used:A kind of electronic water pump impeller, including wheel hub,
Along the cylindrical circumferential direction of wheel hub, multiple homogeneous radiations distributions, shape identical blade are additionally provided with, the outer face of described blade
Orthographic projection be shaped as shaped form, set the water inlet direction of electronic water pump impeller as top, water outlet direction be lower section, described song
It is linear to be divided into three sections from top to bottom, round and smooth mistake between horizontal segment, arc section and vertical section, adjacent both ends is followed successively by respectively
Cross, horizontal segment and vertical section are substantially vertical.The utility model electronic water pump impeller, horizontal segment, shape are added by the blade of impeller
Into blocking surface, volumetric wear, impact loss and the disk abrasion of current can be reduced, the conversion ratio of energy, arc section energy is improved
Enough that current are played with buffering, by blade to front curve, the lift of current when improving high flow capacity, vertical section ensures that lift exists
The smooth-going of whole flow rate zone, three sections of mutual cooperations.
The arc section to central angle be less than or equal to 90 °, the direction of the arc section on each blade is consistent.
The beneficial effects of the utility model are that the blade of impeller is added water by electronic water pump impeller of the present utility model
Flat section, can reduce volumetric wear, impact loss and the disk abrasion of current, improve the conversion ratio of energy, arc section passes through leaf
Piece to front curve, the lift of current when improving high flow capacity, vertical section ensure lift whole flow rate zone smooth-going, three
Section cooperates so that the motor utilization rate of the electronic water pump with the impeller reaches 35%, and energy consumption is small, efficiency high.

Fig. 2 is the front view of the utility model electronic water pump impeller.
In figure:1st, wheel hub, 2, blade, 21, horizontal segment, 22, arc section, 23, vertical section.
Embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model.
As illustrated in fig. 1 and 2, it is the utility model optimum embodiment, a kind of electronic water pump impeller, including wheel hub 1, along wheel hub
1 cylindrical circumferential direction, is additionally provided with multiple homogeneous radiations distribution, shape identical blade 2, the outer face of described blade 2
Orthographic projection (orthographic projection of angle as shown in Figure 2) is shaped as shaped form, sets the water inlet direction of electronic water pump impeller as top, goes out
Water direction is lower section, and described shaped form is divided into three sections from top to bottom, and horizontal segment 21, arc section 22 and vertical are followed successively by respectively
Equal rounding off between section 23, adjacent both ends, horizontal segment 21 and vertical section 23 are substantially vertical.Arc section 22 to central angle it is small
In equal to 90 °, the direction of the arc section 22 on each blade 2 is consistent.
Using it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, pass through above-mentioned description, related work people
Member can carry out various changes and amendments in the range of without departing from this utility model technological thought completely.This reality
The content on specification is not limited to new technical scope, it is necessary to its technology is determined according to right
Property scope.
