Description

Technical Field

[0001] The utility model relates to the technical field of rotors, in particular to a low-noise water pump rotor. Background Art

[0002] The rotor of the water pump is equipped with impellers, thrust blocks and other parts, which is the power device of the water pump. When the electronic water pump is working, the water pump rotor rotates at high speed. Since the water inlet of the impeller is a low-pressure area relative to the water outlet of the water pump, a negative pressure area will be formed in some water pumps with higher head. In this way, a pressure difference is formed in the front and rear areas of the water pump rotor impeller. When the water pump is working normally, it will move forward under the action of the pressure difference, so there will be a thrust block on the water pump rotor to prevent the rotor from moving forward.

[0003] For example, the utility model patent with patent number 201920350560.8 discloses an electronic water pump rotor, which includes an impeller, a rotating shaft, a graphite bearing, a thrust block and a rotor, wherein the impeller is connected to the rotating shaft, the rotating shaft is connected to the graphite bearing, the graphite bearing is connected to the thrust block, the thrust block is connected to the rotor, and the rotor includes positioning columns, which are evenly distributed on the contact surface of the rotor and the thrust block. However, it is difficult to ensure the limiting effect by only using positioning columns and positioning holes for limiting, and the limiting mechanism is single. In view of this, a low-noise water pump rotor is proposed. Utility Model Content
