Problems solved by technology

The stator shielding sleeve and rotor shielding sleeve of shielded motors are usually made of non-magnetic materials, which increases the effective non-magnetic gap between the stator and the rotor, reaching several times the air gap of ordinary motors; resulting in increased power consumption of electric pumps Large, the efficiency is much lower than the ordinary motor with the same power and the same number of poles, and the power factor is lower

Embodiment Construction

[0009] The invention includes a shielding sleeve 1, the middle of which is a magnetically permeable material part 2 corresponding to the rotor 5 iron core or the stator 6 iron core, and the outside of the middle magnetically permeable material part 2 of the shielding sleeve 1 is a non-magnetically permeable material part 3.

[0010] The thickness of the shielding sleeve 1 may be 0.5 mm.

[0011] The shielding sleeve 1 of the present invention can be used not only as the stator shielding sleeve 1 of the shielded motor 4 , but also as the rotor shielding sleeve 1 of the shielded motor 4 .

[0012] The shielded electric pump includes a pump 9 and a shielded motor 4. Between the shaft 8 and the housing 7 of the shielded motor 4 are a stator 6 and a rotor 5. The stator 6 and the rotor 5 are respectively provided with a shielding sleeve 1, and the stator 6 has an iron core and a rotor. 5. The iron core corresponds to the middle magnetically permeable material part 2 of the shielding...

Abstract

A shield cover structure relates to an improvement of a shield cover structure of a canned motor pump. The invention provides the shield cover structure capable of enhancing efficiency of canned motors. The shield cover structure comprises a shield cover, and the structure is characterized in that the middle of the shield cover is equipped with a magnetic conductive material corresponding to a rotor core or a stator core, and the magnetic conductive material in the middle of the shield cover is a non-magnetic conductive material.

Description

Technical field: [0001] The invention relates to the improvement of the structure of the shielding sleeve of the shielded electric pump. Background technique: [0002] Canned electric pump is composed of canned motor and pump. The stator shielding sleeve and rotor shielding sleeve of shielded motors are usually made of non-magnetic materials, which increases the effective non-magnetic gap between the stator and the rotor, reaching several times the air gap of ordinary motors; resulting in increased power consumption of electric pumps Large, the efficiency is much lower than the ordinary motor with the same power and the same number of poles, and the power factor is lower. Invention content: [0003] The present invention aims at the above problems and provides a shielding sleeve structure that can improve the efficiency of a shielded motor. [0004] In order to achieve the above object, the present invention adopts the following technical scheme. The present invention in...
