Description

Technical Field

[0001] The utility model relates to the technical field of shielding sleeves, in particular to a shielding sleeve of a rotor. Background Art

[0002] The shielded pump uses the same shaft to fix the motor rotor and the pump impeller together, and then uses a shielding sleeve to shield the rotor group. The stator of the motor surrounds the shielding sleeve. The shielding sleeve is made of metal, so the power can be transmitted to the rotor through the magnetic field, and the entire rotor is running in the pumped liquid. The end of the shield is statically sealed by a flange or welded structure. The shielding sleeve is actually a pressure vessel.

[0003] According to the description of a reinforced shielding sleeve disclosed in the patent website (authorization announcement number: CN 212803691 U), "The utility model proposes a reinforced shielding sleeve, including a shielding sleeve body, the first end of the shielding sleeve body is closed and the second end thereof is open, a connecting platform extending outward is provided on the outside of the second end of the shielding sleeve body, an annular groove coaxially arranged with the shielding sleeve body is provided in the middle of the connecting platform, and a plurality of first reinforcing ribs are circumferentially arranged on the outside of the shielding sleeve body, and the first reinforcing ribs are axially arranged along the shielding sleeve body and extend into the annular groove. The utility model improves the overall strength of the shielding sleeve by arranging first axial reinforcing ribs on the outside of the shielding sleeve body and arranging third reinforcing ribs at the bottom end of the inside of the shielding sleeve body, thereby improving the stability of the working performance of the shielding sleeve in a high temperature, high pressure and strong vibration working environment and extending the service life of the shielding sleeve."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model can improve the overall strength of the shielding sleeve by providing reinforcing ribs inside and outside the shielding sleeve, thereby extending its service life. However, in actual use, the first reinforcing ribs outside the insulating sleeve are distributed in a circular shape outside the insulating sleeve, and there is no support between the reinforcing ribs, resulting in poor stability. Under high temperature conditions, the high-speed rotating rotor will still have an impact on the shielding sleeve, causing the shielding sleeve to deform. Therefore, it is necessary to improve a rotor shielding sleeve to solve the above problem. Utility Model Content
