Description

Technical Field

[0001] The utility model relates to a magnetic pump, more specifically, to a novel split magnetic pump. Background Art

[0002] At present, the magnetic pump transmits magnetic force through the drive shaft assembly and the sliding shaft assembly. The structure of the transmission pump head is complex, requiring sliding bearing assemblies, sleeves, protective sleeves, bushings, sliding bearing sleeves, push plate assemblies, various gaskets and pins and other parts, and relying on isolation sleeves to prevent material leakage. Isolation sleeves are expensive and easy to be damaged and cause material leakage. The drive shaft assembly also requires rolling bearings, bearing frames, bearing glands, bearing bodies, drive assemblies, vent plugs, magnetic sheets, etc. The motor rotates to drive the drive shaft assembly to rotate, so that the magnetic force rotates, driving the sliding bearing assembly to rotate and drive the impeller to rotate to pump materials. There are many parts, and once a problem occurs in a certain part, it will affect the operation of the pump. The isolation sleeve is very easy to wear, which is the main problem that the pump cannot operate for a long time. After the isolation sleeve leaks, the material flows into the drive shaft assembly through the isolation sleeve and flows out through the vent plug. The high-speed operation of the drive shaft assembly will cause the temperature of the material to rise quickly, and there is a risk of combustion and explosion for flammable and explosive materials.
