MAGNETIC DRIVE PUMP

WIPO Patent Application WO/2016/008407

A1

A magnetic drive pump comprises a pump body (A). A front cavity, a middle cavity and a rear cavity are formed and spaced in the inner side of the pump body (A). An impeller (3) is arranged in the front cavity, and a permanent magnet rotor (5) is arranged in the rear cavity. The middle cavity is a closed water baffle cavity, an electromagnetic stator (4) matched with the permanent magnet rotor (5) is arranged in the middle cavity, and the permanent magnet rotor (5) is connected to the impeller (3) through a central shaft (6) penetrating the middle cavity. In the provided magnetic drive pump, a driving permanent magnet rotor in a magnetic drive mechanism of an existing magnetic drive pump is directly used as a rotor of a motor, and a driven permanent magnet rotor in the existing drive mechanism is replaced with the electromagnetic stator, so that the design concept of the existing magnetic drive pump is overturned completely, the complex internal and external magnetic drive framework of the existing magnetic drive pump is changed completely, the axial length and size of the general magnetic drive pump are greatly reduced, and the magnetic drive pump has a more compact overall structure, a smaller size and lighter weight, saves materials effectively and reduces the production and maintenance costs.
