In order to improve the wear resistance of the impeller, a material with high strength and good wear resistance can be adopted, but the material not only brings difficulty to the impeller manufacturing process, but also increases the production cost; therefore, in order to improve the wear resistance of the impeller and reduce the production difficulty, impellers consisting of a stainless steel body and rubber encapsulation have been developed.
In the prior art, a chinese patent with an authorization publication number of CN204312390U discloses an impeller of a high wear-resistant rubber slurry pump, which comprises blades, a front guard plate and a rear guard plate, wherein the blades are arranged between the front guard plate and the rear guard plate and are uniformly distributed along an axial direction; the middle of the blade, the front guard plate and the rear guard plate is a metal framework, and particularly, the outer layer of the metal framework is made of natural rubber composite material prepared from natural latex by a wet mixing technology.
Although natural rubber has better wear resistance, when the impeller rotates at the speed of thousands of revolutions per minute, the hysteresis loss of the natural rubber generated due to irreversible deformation can be converted into heat energy, so that the internal temperature of the rubber is increased, the hardness of the rubber is reduced, the deformation is increased, the bonding force between the rubber and the metal framework of the impeller is reduced, and the use of the impeller is influenced; moreover, as the natural rubber is nonpolar rubber, the natural rubber can only resist some lower ketones and alcohols, but can swell in nonpolar solvents, and the oil resistance and the solvent resistance of the natural rubber are poor, so that the impeller cannot be used in fuel oil; therefore, the conventional wear-resistant material for the impeller still has certain defects.
