PERMANENT MAGNET DIRECT DRIVE SLURRY PUMP HAVING WATER COOLING CIRCULATION STRUCTURE

WIPO Patent Application WO/2021/227262

A1

A permanent magnet direct drive slurry pump having a water cooling circulation structure, comprising a pump body and a permanent magnet synchronous motor, and further comprising a cooling water tank (29). The pump body and the permanent magnet synchronous motor are directly mounted and connected, and share one axis (8); the permanent magnet synchronous motor further comprises a built-in cooling liquid drive device; the built-in cooling liquid drive device is mounted in a motor housing (7) of the permanent magnet synchronous motor; the cooling water tank (29), the built-in cooling liquid drive device, and a cooling liquid channel formed in the motor housing (7) form a cooling circulation channel. The structure can improve the transmission efficiency, reduce a failure rate, and improve the recycling efficiency of cooling liquid, and can also offset the axial force generated during the working process of the slurry pump.
