Abstract

The invention discloses a mini-type magnetic transmission centrifugal pump. A rotor is assembled through an impeller, inner magnetic steel and a pump shaft. A bearing is arranged in a pump body, and the rotor is placed in the pump body. Cushioning of a sealing ring is conducted, a pump sealing cover is screwed, and an electromagnet and a circuit board are installed. An electromagnetic field generated by the electromagnet penetrates the pump body made of 430 magnetic conductive stainless steel and acts on the inner magnetic steel, and the inner magnetic steel rotates by cutting the magnetic field. The whole rotor is driven to rotate through rotation of the inner magnetic steel, and finally the water pump is made to work.

Description

Technical field [0001] The invention relates to a miniature magnetic drive centrifugal pump device, in particular to a water pump with small size, light weight, simple structure and no leakage. Background technique [0002] For a long time, the structure of the magnetic drive centrifugal pump has remained unchanged, that is, the pump body, impeller, inner magnetic steel assembly, shaft sleeve, spacer sleeve, outer magnetic steel assembly, coupling frame, motor, thrust ring, pump shaft, moving ring, Static ring, sealing ring, drain bolt. Therefore, there are deficiencies in aspects such as large volume, heavy weight, and complex structure. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiency of the existing magnetic drive centrifugal pump, and the present invention provides a miniature magnetic drive centrifugal pump. The miniature magnetic drive centrifugal pump is not only small in size and light in weight, but also simpl...
