Double-wall containment shroud of a magnetic coupling, in particular a magnetic coupling pump

摘要

A magnetic coupling, in particular a magnetic coupling pump, includes an inner rotor and an outer rotor which each carry magnets. Disposed between the inner and outer rotors is a double-wall containment shroud, which includes an outer shroud and an inner shroud. Each of the inner and outer shrouds includes a flange, a middle section and a bottom section, wherein a gap is disposed between the middle section and the bottom section. The inner shroud is connected by its flange to the flange of the outer shroud. The gap is filled at least in sections with a solid material.

1. A magnetic coupling, comprising:
an inner rotor carrying magnets; an outer rotor carrying magnets; a double-wall containment shroud disposed between the inner and outer rotors and including an outer shroud and an inner shroud, each of the inner and outer shrouds having a flange, a bottom section, and a middle section between the flange and the bottom section, with the flange of the inner shroud connected to the flange of the outer shroud, said the inner and outer shrouds being composed of metal and defining a gap there between in an area of the middle sections and the bottom sections; and a solid material filled in the gap at least in one section thereof, wherein the solid material is a heat-conducting plastic providing a heat transfer from the outer shroud to a conveying medium.
