Detailed Description

Embodiments of the present invention are further described with reference to fig. 1 to 4.

The utility model discloses a double-impeller automobile electronic cooling water pump, which comprises a cylindrical shell 1, a pump cover 2 and a bottom cover 3 which are arranged at two ends of the shell 1, wherein the pump cover 2 is provided with a water inlet 20 and a water outlet 21, a double-impeller component 4 is arranged in the pump cover 2, a driving motor 10 for driving the double-impeller component 4 to rotate is arranged in the shell 1, the double-impeller component 4 comprises a water inlet ring 41 and a base 40 which is fixed on an output shaft of the driving motor 10, first blades 400 are evenly distributed on the base 40 in the circumferential direction, the end parts of the first blades 400 are provided with first fixture blocks 401, the water inlet ring 41 is buckled on the base 40 in a clearance arrangement, the water inlet ring 41 is provided with first clamping grooves 410 which are matched with the first fixture blocks 401, a rotating groove 22 which is matched with the water inlet ring 41 is arranged in the pump cover 2, the water inlet ring 41 is provided with a water through opening 411 which is communicated with the water, second blades 412 staggered with the first blades 400 are uniformly distributed on the inner wall of the water through opening 411, second clamping blocks 413 are arranged at the end parts of the second blades 412, and second clamping grooves 402 matched with the second clamping blocks 413 are arranged on the base 40. The number of the first blades 400 is at least three, and the number of the second blades 412 is the same as that of the first blades 400. A buffering protrusion 403 is disposed at the center of the base 40.

The working principle is as follows: when starting the electronic cooling water pump, driving motor 10 can drive base 40 and rotate, and the first blade 400 that distributes on base 40 this moment can rotate, and when first blade 400 rotated, because first fixture block 401 that first blade 400 tip set up cooperatees with the first draw-in groove 410 of water ring 41 for can drive water ring 41 and rotate in the rotation groove 22 of pump cover 2 when first blade 400 rotated.
