If the pumping of flammable, explosive and toxic harmful media occurs in unexpected conditions, the phenomenon of medium leakage and seepage occurs, and the pumping has great harm to production safety, environment and personnel. The magnetic pump is used for conveying inflammable, explosive, poisonous and harmful media due to good sealing property. However, as society advances, the safety requirements for equipment are also increasing.
The double-layer isolation sleeve of the magnetic pump in the prior art is formed by combining a metal inner sleeve and a metal outer sleeve, wherein the metal inner sleeve and the metal outer sleeve are fixedly connected in a sealing way or welded in a sealing way through bolts and sealing gaskets, and an interlayer closed cavity between the inner sleeve and the outer sleeve is formed, so that the double-layer sealing anti-leakage performance of the isolation sleeve is formed. However, the magnetic eddy current loss is multiplied due to the increase of the thickness of the double-layer metal isolating sleeve, so that the efficiency of the low-magnetic force pump is greatly reduced.
