the impeller formed by splicing adopts a split design, the two ends of the blade are respectively riveted with the upper cover disc and the lower cover disc through rivets, and the impeller riveted through the rivets easily has the problems of low connection strength, weak resultant force, easy falling off and the like in use; in addition, the flatness of the upper cover plate and the lower cover plate of the impeller riveted by the rivets cannot be guaranteed, so that the problem of roughness and unevenness can be caused, and the use performance of the impeller is further influenced.
Disclosure of Invention
The utility model aims at providing a novel water pump centrifugal impeller that processing assembly is simple, the product is smooth, performance is good to the above-mentioned problem that exists among the prior art.
The purpose of the utility model can be realized by the following technical proposal: the utility model provides a novel water pump centrifugal impeller, a serial communication port, including upper cover dish and lower cover dish, upper cover dish on have a plurality of be circumference evenly distributed's blade, lower cover dish on the position department of corresponding blade have a plurality of be circumference evenly distributed's card strip, the quantity of card strip and blade is the same, all set up the draw-in groove that supplies corresponding card strip to stretch into the joint on each blade, card strip and draw-in groove one-to-one joint make upper cover dish and lower cover dish amalgamation link firmly.
In foretell a novel water pump centrifugal impeller, card strip top protruding in proper order have first joint portion and second joint portion, the blade on set gradually and supply corresponding first joint portion and second joint portion to stretch into joint and the first joint groove and the second joint groove that are linked together with the draw-in groove.
In the novel water pump centrifugal impeller, the clamping strip and the clamping groove are fixed by welding.
In the above-mentioned novel water pump centrifugal impeller, the middle part of upper cover dish and lower cover dish all sets up the axle hole portion of intercommunication each other.
Compared with the prior art, this novel water pump centrifugal impeller has following advantage:
1. the clamping strips, the first clamping parts and the second clamping parts in the lower cover disc are in one-to-one corresponding connection and matching with the clamping grooves, the first clamping groove parts and the second clamping groove parts in the upper cover disc, so that the upper cover disc and the lower cover disc can be firmly welded conveniently, the smoothness of the impeller is improved, and the appearance of the impeller is more attractive;
2. the impeller has the advantages that the blades and the upper cover disc are integrally formed in a punching mode, the clamping strips and the lower cover disc are integrally formed in a punching mode, and the upper cover disc with the blades and the lower cover disc with the clamping strips are designed in a split mode, so that compared with the traditional impeller formed by integral casting, the impeller has higher size precision, can better guarantee the stability of the performance of the impeller, is controllable in punching and forming weight, and can greatly reduce product cost;
3. this blade in impeller and the integrative stamping forming of upper cover dish and welded fastening compare the tradition and have that joint strength is higher, more stable advantage through rivet and upper cover dish and lower cover dish riveted method to can effectual reduction because of the pump accident risk that the blade drops and arouses, improve the reliability of pump operation.

Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in figures 1, 2, 3, 4, 5 and 6, the novel centrifugal impeller for the water pump comprises an upper cover disc 1 and a lower cover disc 2, wherein a plurality of blades 3 which are uniformly distributed in the circumferential direction are arranged on the upper cover disc 1, the blades 3 and the upper cover disc 1 are formed by integral punch forming, a plurality of clamping strips 4 which are uniformly distributed in the circumferential direction are arranged at positions on the lower cover disc 2 corresponding to the blades 3, the clamping strips 4 and the lower cover disc 2 are formed by integral punch forming, the quantity of the clamping strips 4 is the same as that of the blades 3, clamping grooves 5 for the corresponding clamping strips 4 to extend into the clamping are formed in each blade 3, the clamping strips 4 and the clamping grooves 5 are correspondingly clamped to ensure that the upper cover disc 1 and the lower cover disc 2 are spliced and fixedly connected, a first clamping part 6 and a second clamping part 7 are sequentially protruded at the top of the clamping strips 4, a first clamping groove 8 and a second clamping groove 9 which are sequentially provided for the corresponding first clamping part 6 and the second clamping part 7 to extend into the clamping and are communicated with the clamping grooves 5 are sequentially, through welded fastening between card strip 4 and the draw-in groove 5, the axle hole portion 10 that communicates each other is all seted up at the middle part of upper cover dish 1 and lower cover dish 2.
