Description
Technical Field
The invention relates to an isolation sleeve device of a magnetic pump.
Background
If an accident happens to the flammable, explosive and toxic harmful medium pumped, the medium is leaked, overflowed and leaked, and the damage to the production safety, the environment and the personnel is great. The magnetic pump is used for conveying inflammable, explosive, toxic and harmful media due to good sealing performance. However, with the progress of social development, the requirements on the safety of equipment are continuously increased.
The double-layer isolation sleeve of the magnetic pump in the prior art is used for improving the anti-leakage capacity of the isolation sleeve and 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 through a bolt and a sealing gasket or fixedly connected in a welding way, and an interlayer closed cavity between the inner sleeve and the outer sleeve is formed to form the double-layer sealing anti-leakage of the isolation sleeve. However, due to the increase of the thickness of the double-layer metal isolation sleeve, the magnetic eddy current loss is multiplied, so that the efficiency of the magnetic pump is greatly reduced.
