Isolation cover assembly of magnetic force pump

The invention discloses an isolation cover assembly of a magnetic force pump. The isolation cover assembly comprises an internal isolation cover, an external isolation cover, an electric heating mechanism, a circular heat conducting strip and a lining ring, wherein the internal isolation cover consists of an internal isolation cover flange, an internal isolation cover thin-wall barrel and an internal isolation cover bottom plate; the external isolation cover consists of an external isolation cover flange, an external isolation cover thin-wall barrel and an external isolation cover bottom plate; the lining ring is located between the internal isolation cover and the external isolation cover; a sealed cavity is formed among the internal isolation cover, the external isolation cover and the lining ring; the circular heat conducting strip is arranged in the middle part of the internal isolation cover bottom plate; the circular heat conducting strip is connected with the electric heating mechanism. As the isolation cover assembly of the magnetic force pump provided by the invention adopts such a structure, a heat source can reach an easy-to-crystallize medium area at an internal magnetic rotor after shut-down; therefore the restart resistance of the magnetic force pump is decreased; the service life of the magnetic force pump is prolonged; moreover, the damage of the isolation cover can be discovered in time, so that a leakage accident is avoided.
