Problems solved by technology

[0004] The impeller blades of the existing automobile water pump rotor are integrally formed plastic or metal parts, and the metal parts have the problems of heavy weight and low efficiency
However, the commonly used plastic water pump rotors have insufficient mechanical strength, poor temperature resistance and low strength. When used in extremely harsh environments, they are prone to cracking and other strength problems, which eventually lead to cooling devices. fail

Abstract

The invention relates to the technical field of injection molding permanent magnet materials, and discloses a high-strength car water pump rotor and a manufacturing method thereof. The high-strength car water pump rotor comprises a rotor main body made of PPS- ferrite, a rubber coating layer made of modified reinforced PPS and a graphite bearing, the modified reinforced PPS is PPS modified and reinforced through glass fibers and carbon fibers, the adding amount of the glass fibers or carbon fibers in the modified reinforced PPS is not higher than 40%, and the amount is optimized to 25 to 35%.Through methods of material optimization, process improvement and the like of the high-strength car water pump rotor, compared with the prior art, the produced rotor has the advantage of stable running under the extremely severe environment.

Description

technical field [0001] The invention relates to the technical field of injection molding permanent magnet materials, in particular to a high-strength automotive water pump rotor and a manufacturing method thereof. Background technique [0002] Automotive water pumps generally have self-priming functions, and micro-pumps with self-priming capabilities are also called "miniature self-priming pumps". It combines the advantages of self-priming pumps and chemical pumps, and is made of a variety of corrosion-resistant imported materials, which have properties such as acid resistance, alkali resistance, and corrosion resistance; the self-priming speed is extremely fast (about 1 second), and the suction The distance is as high as 5 meters, basically no noise; the workmanship is exquisite, not only has the function of self-priming, but also has a large flow rate (up to 25 liters per minute), high pressure (up to 2.7 kg), stable performance, and easy installation, so the new energy T...
