Before the disassembly and maintenance of the magnetic coupling actuator of the laboratory reaction kettle, Lab Scale Glass Reactor the materials in the kettle should be drained and the pressure should be released. If the reaction medium is flammable, Lab Scale Glass Reactor explosive or toxic, Lab Scale Glass Reactor it should be cleaned before disassembly. After the laboratory reactor experiment process is completed, Lab Scale Glass Reactor first remove the tachometer components on the upper end of the sealed cover. Then remove the main bolts connecting the kettle cover part and the kettle body part, Lab Scale Glass Reactor remove the kettle cover part together with the magnetic coupling drive, Lab Scale Glass Reactor loosen the coupling, and remove the lower stirring shaft part and the coupling together. Then unscrew the thread connecting the cooling body of the magnetic coupling actuator and the kettle lid, Lab Scale Glass Reactor and remove the magnetic coupling actuator from the kettle lid part.
The second step is to unscrew the thread connecting the top cover of the reaction kettle and the cooling body with the sealing cover, Lab Scale Glass Reactor and pull out the sealing cover together with the inner and outer magnetic steel rotors and the upper stirring shaft, Lab Scale Glass Reactor so that the flange cooling body is removed.
Then according to the structural drawing, take out and replace the graphite composite bushing I; take out and replace the composite bushing II. In order to prevent the high temperature expansion of the bushing and squeeze the stirring shaft, Lab Scale Glass Reactor the graphite composite bushing should adopt a larger clearance fit. If the fit is tight, Lab Scale Glass Reactor the bushing needs to be sharpened during assembly.
During the maintenance process, special care should be taken to prevent foreign objects from falling into the kettle and damaging the inner surface or sealing surface of the kettle. In short, Lab Scale Glass Reactor the disassembly and maintenance of the magnetic coupling drive should be performed by equipment manufacturer professionals or personnel trained by the equipment manufacturer, Lab Scale Glass Reactor and a clean and hygienic place should be selected to avoid impurities such as ferromagnetic materials entering the gap between the inner and outer magnetic steel. And to ensure the concentricity of the inner and outer magnetic steel and the sealing cover, so as not to cause the inner and outer rotor wear. Be careful not to damage the sealing cover body, Lab Scale Glass Reactor which affects the bearing strength. If it is accidentally damaged, Lab Scale Glass Reactor it should be repaired in time.
