Description

technical field

[0001] The invention belongs to the technical field of liquid conveying pumps, and more specifically, belongs to an array hybrid magnetic bearing magnetic drive pump. Background technique

[0002] In the prior art hybrid bearing magnetic pump unit, the low bearing capacity and short service life of the bearing are common problems. The main reason is that the traditional hybrid bearing is a simple annular radially magnetized magnetic steel with low bearing capacity. When the speed is high, it is prone to friction failure, which affects the normal operation of the magnetic pump. Contents of the invention

[0003] In order to solve the above technical problems and avoid the shortcomings of the prior art, the present invention provides a hybrid magnetic levitation magnetic pump device, thereby effectively solving the problems in the prior art.

[0004] An array hybrid magnetic bearing magnetic pump of the present invention includes a base part, a power part, a...
