Technical Field

[0001] The utility model relates to the technical field of impeller magnetic rings, in particular to a novel water pump impeller rotor. Background Art

[0002] Water pump impeller rotors are used in existing automobiles. The water pump impeller rotors include an impeller, an impeller cover, an impeller shaft, an impeller magnetic ring, a rotor core and a plastic shell. The impeller magnetic ring and the rotor core are arranged inside the plastic shell. The plastic shell is formed by injection molding plastic material to form a rotor main body shell, and finally forms a water pump impeller rotor.

[0003] The existing water pump impeller rotor is prone to the following problems during use. First, when the water pump impeller rotor is used for a long time, a large amount of heat is easily generated inside the impeller rotor, and the rotor main body shell is made of plastic, which has poor high temperature resistance, making the rotor main body shell easy to age and reduce its service life. Second, the impeller is composed of multiple blades. When one of the blades is damaged, the entire impeller needs to be replaced, which wastes production materials and increases economic investment costs. Therefore, in response to the above problems, we have proposed a new water pump impeller rotor. Utility Model Content

[0004] The purpose of the utility model is to provide a new type of water pump impeller rotor to solve the problems that, firstly, a large amount of heat is easily generated inside the impeller rotor when the water pump impeller rotor is used for a long time, and the rotor main body shell is made of plastic, which has poor high temperature resistance, so that the rotor main body shell is easy to age and reduce the service life; secondly, the impeller is composed of multiple blades. When one of the blades is damaged, the impeller needs to be replaced as a whole, thereby wasting production materials and increasing the economic investment cost.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A novel water pump impeller rotor comprises a plastic shell, an impeller shaft, an impeller magnetic ring, an impeller body and blades, wherein the inner wall of the plastic shell is fixedly connected with a heat-resistant coating, the inner wall of the heat-resistant coating is fixedly connected with a reinforcing rib, the outer side of the plastic shell is fixedly connected with a heat dissipation fin, an impeller shaft is arranged inside the plastic shell, an impeller magnetic ring is arranged outside the impeller shaft, an impeller body is arranged outside the impeller shaft, blades are arranged outside the impeller body, a push rod is arranged at the upper end of the impeller body, a clamping groove is opened on the inner side of the upper and lower ends of the blades, a placement groove is opened on the inner side of the impeller body, a compression spring is fixedly connected to the inner side of the placement groove, the other end of the compression spring is fixedly connected to a connecting block, the other end of the connecting block is fixedly connected to a sliding plate, and the other end of the sliding plate is fixedly connected to a clamping block.

[0007] Preferably, there are a plurality of reinforcing ribs, each of which is in a circular shape, and there are a plurality of heat dissipation fins, each of which is in a rectangular shape.

[0008] Preferably, the impeller magnetic ring is located inside the plastic shell, the impeller magnetic ring is located at the lower end of the impeller body, and the number of the blades is twelve.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In the utility model, a heat-resistant coating, reinforcing ribs and heat dissipation fins are provided to form a reinforced heat-resistant component. The heat-resistant coating improves the heat resistance of the plastic shell. The heat dissipation fins increase the heat dissipation area of ​​the plastic shell, so that the internal temperature of the plastic shell is dissipated in time, thereby reducing the aging of the plastic shell due to excessive temperature. The reinforcing ribs provide auxiliary support to the inside of the plastic shell, strengthen the supporting strength of the internal structure of the plastic shell, and thereby improve the overall service life of the plastic shell. By providing a compression spring, a connecting block, a sliding plate, a clamping block and a clamping groove, a clamping groove is opened on the inner side of the upper and lower ends of the blade. The compression spring provides a reverse force to drive the connecting block, the sliding plate and the clamping block to move inward, so that the lower end of the clamping block is clamped in the clamping groove to fix the blade. When individual blades are damaged, the maintenance personnel pull the push rod outward by hand, and the push rod drives the connecting block, the sliding plate and the clamping block to move outward, so that the clamping block leaves the clamping groove, and then removes the damaged blade and replaces it. The process is simple to operate, and there is no need to replace the impeller body as a whole, saving production materials and reducing economic investment costs. BRIEF DESCRIPTION OF THE DRAWINGS
