Description
Technical Field
The utility model relates to an electronic pump technical field specifically is an electronic pump wear-resisting component.
Background
At present, an electronic water pump is a common micro water pump for new energy automobiles, motor homes, special vehicles and the like, and is generally used as a water circulation, cooling or water supply system on the vehicles. Under the action of pressure difference, the electronic water pump presses water into the water inlet and then discharges the water from the water outlet, and the water is continuously sucked and discharged under the action of kinetic energy transmitted by the motor to form stable flow.
When the electronic water pump is assembled, the water pump impeller penetrates through the positioning shaft of the motor assembly, when the motor obtains a power supply signal through the plug connector, the controller transmits a signal to the motor, the coil of the water pump impeller induction motor is reversed to work, the water pump impeller can be outwards strung out when the water pump impeller works, the water pump impeller is rubbed with a pump shell, the water pump impeller is clamped, and the electronic water pump is damaged and the service life of the electronic water pump is shortened.
Disclosure of Invention
In order to solve the technical problem, the utility model provides an electronic pump wear-resisting component.
The utility model discloses the technical problem that will solve adopts following technical scheme to realize:
the end part of the stator shaft is provided with a wear-resistant gasket which is tightly combined with the pump shell and the impeller rotor assembly so as to reduce the wear between the impeller rotor assembly and the pump shell, and the wear-resistant gasket is static in the circumferential direction relative to the impeller rotor assembly.
As a further improvement of the utility model, be equipped with the stopper that the terminal surface is non-circular structure on the tip of stator axle.
As a further improvement of the utility model, the wear-resistant gasket is provided with a non-circular limiting hole.
The utility model has the advantages that:
the utility model discloses a set up the stopper on the stator shaft, fix wear-resisting gasket on the stator shaft and with the spacing cooperation of stopper for circular motion is not done to wear-resisting gasket, simultaneously with pump case, impeller driving fit, makes impeller and wear-resisting gasket have a small amount of friction, has avoided impeller and pump case direct contact, and then leads to the dead phenomenon of impeller card, has reduced impeller wearing and tearing, has prolonged water pump life.
Drawings
The invention will be further described with reference to the following figures and examples:
fig. 1 is an exploded schematic view of the present invention;
FIG. 2 is a schematic view of the stator shaft and the limiting block of the present invention;
fig. 3 is a schematic view of the wear-resistant pad of the present invention.
Detailed Description
In order to make the technical means, creation features, achievement purposes and effects of the present invention easy to understand, the present invention will be further explained with reference to the accompanying drawings and embodiments.
As shown in fig. 1 to 3, an electronic water pump wear-resistant assembly sequentially includes a pump housing 1, an impeller rotor assembly 3, a motor assembly 4 with a stator shaft 10, a rubber support 5, a controller assembly 6, a seal ring 7, a motor rear cover 8, and a screw 9 for connection, wherein a stopper 101 with a non-circular end surface is disposed on an end portion of the stator shaft 10, specifically, the non-circular end surface of the stopper 101 is composed of an arc line and a straight line connecting two ends of the arc line, a wear-resistant gasket 2 tightly fitted with the pump housing 1 and the impeller rotor assembly 3 is disposed on the stopper 101, the wear-resistant gasket 2 is a circular structure, a non-circular-shaped stopper hole 2a is disposed in a center of the stopper 101, specifically, the shape of the stopper hole 2a is similar to the shape of the end surface of the stopper 101, and a maximum outer diameter of the end surface of the stopper 101 and a minimum inner diameter of the stopper hole, through the mutual matching between the limiting hole 2a and the limiting block 101, the wear-resistant gasket 2 is limited in the circumferential direction, and compared with the existing wear-resistant gasket which is directly clamped on a pump shell, the phenomenon that the wear-resistant gasket 2 rotates along with the impeller rotor assembly 3 in a synchronous circumferential mode is avoided; secondly, from the structure itself, the wear-resistant gasket 2 is made of ceramic material or 304 stainless steel, the surface is treated by an anti-corrosion coating, the service life of the wear-resistant gasket 2 is greatly prolonged, in addition, the thickness of the wear-resistant gasket 2 in the utility model is between 0.4 and 0.5mm, and compared with the thickness of the wear-resistant gasket in the existing electronic water pump which is only 0.1mm, the wear-resistant gasket 2 in the utility model has the advantage of long wear-resistant time; finally, most importantly, after the impeller axial force is reserved to form a serial gap, the wear-resistant gasket 2 is firmly and closely attached to the pump shell 1 and the impeller rotor assembly 3, the impeller rotor assembly 3 is directly prevented from contacting the pump shell 1, the impeller rotor assembly 3 is prevented from being stuck and damaged, and the service life of the water pump is prolonged.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and what is described in the specification are the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the present invention, and these changes and modifications are intended to fall within the scope of the present invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
