Title:
INTEGRATED WATER PUMP FOR PREVENTING IMPELLER DEPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/060843
Kind Code:
A1
Abstract:
An integrated water pump for preventing impeller deposition, the integrated water pump comprising a water pump outer cylinder (1), a stator assembly (2), a rotor assembly (3), and a flow guide housing (4). The water pump outer cylinder (1) and an outer wall of the stator assembly (2) enclose a first space (33), and an outer wall of the rotor assembly (3) and an inner wall of the stator assembly (2) enclose a second space (36); the flow guide housing (4) is internally provided with a mounting cavity (46) for an impeller (40), a vortex groove (47) is formed in a peripheral wall of the mounting cavity (46), and a water permeable hole (56) is formed inside the flow guide housing (4); a water intake end of the water pump, the vortex groove (47), the first space (33) and a water output end of the water pump form a first flow channel; and the water intake end of the water pump, the water permeable hole (56), the second space (36) and the water output end of the water pump form a second flow channel. The two flow channels of the water pump are used for cooling an electric motor.
