MAGNETIC CONNECTION PERIPHERAL PUMP

摘要

PROBLEM TO BE SOLVED: To improve miniaturization and durability by receiving by a partition board the thrust force of a motor rotor generated by the attraction of a combined magnet, and arranging the vane of a pump on the periphery of a driven magnet. SOLUTION: A pump chamber 12 in which an impeller 14 rotated integrally with a driven magnet 16 is arranged and a power source side are partitioned in security by a partition board 20, and also a motor rotor 28 on which a driving magnet 27 is mounted is arranged on the opposed power source side across the partition board 20. The rotary shaft of the rotor 28 can be moved to a bearing part arranged in the center part of an iron core, and also the thrust force of the rotor 28 generated by the attraction of a combined magnet is received by the partition board 20.
