Abstract
The utility model discloses an inverse heat preservation magnetic pump, comprising a pump body, a pump body heat preservation sleeve, a pump shaft, an impeller, an inner magnetic rotor, an outer magnetic rotor, an insulation sleeve, a motor and a linkage frame. The pump body heat preservation sleeve is sleeved on the pump body; a steam inlet and a steam outlet are arranged at the outer side of the pump body heat preservation sleeve; a bearing body is further arranged between the pump body and the linkage frame; the pump body heat preservation sleeve and the bearing body both have a double-layer structure; a steam inlet and a steam outlet are also arranged at the outer side of the bearing body; the steam outlet in the bearing body is communicated with the steam inlet in the pump body heat preservation sleeve; the outer magnetic rotor is located inside the bearing body and is connected with the pump shaft; the front end of the inner magnetic rotor extends into the outer magnetic rotor, and the rear end of the inner magnetic rotor is connected with the motor shaft; and the insulation sleeve is arranged inside the outer magnetic rotor and is located between the inner magnetic rotor and the outer magnetic rotor. According to the inverse heat preservation magnetic pump provided by the utility model, the problem that the conventional magnetic pump has poor heat preservation effect can be effectively solved.
Description
Technical field
The utility model relates to a kind of magnetic drive pump, relates in particular to a kind of reverse insulation magnetic drive pump.
Background technique
Common magnetic drive pump external rotor is contained on the motor, and separation sleeve is not delivered on the motor for making heat in external rotor, and external rotor all is with fan blade cooling, so the separation sleeve position can't be incubated, and temperature descends serious during pump operation.When carrying some materials, can cause damage to material or pump because of being incubated.Phthalic anhydride for example, the full name phthalic anhydride is one of important Organic Chemicals, under the normal temperature, the phthalic anhydride crystallization is the sheet white solid, 131.6 ℃ of fusing points.What phthalic anhydride adopted in commercial production is the catalytic gas phase oxidation method of ortho-xylene, and its oxidizing temperature is up to 440 ℃, and the extraction temperature of liquid phthalic anhydride is also up to 180～250 ℃.Therefore; Carry the equipment and technology of phthalic anhydride plant to require very high; Because phthalic anhydride is the high-melting-point material, open, in the docking process, as using mechanical seal; Then the temperature of mechanical seal place often is lower than the material melting temperature; The a small amount of phthalic anhydride of meeting appearance solidifies or crystal is separated out phenomenon, and bellows can be lost elasticity gradually because of reasons such as obstructions, and friction pair lost efficacy; Cause pump to leak, often shorten dramatically because of frequently opening, stopping the service life of phthalic anhydride pump mechanical sealing; As use common magnetic drive pump to carry the medium of this type of phthalic anhydride normal temperature with regard to crystallization; Can not accomplish to be incubated fully to flow passage components; Make the place of insulation difference that crystallization arranged; Serious wear during the pump running; Pump service life is short, and the liquid storage crystallization is arranged after the termination of pumping, just can start pump after crystal is melted; Nonetheless also there is crystal not exclusively to melt, starts the back greatly the pump infringement.
Summary of the invention
To the problem that exists in the above-mentioned existing technology, the purpose of the utility model just is to provide a kind of reverse insulation magnetic drive pump, can effectively solve the problem of existing magnetic drive pump heat insulation effect difference.
To achieve these goals; The technological scheme that the utility model adopts is such: a kind of reverse insulation magnetic drive pump, comprise the pump housing, pump housing lagging, pump shaft, impeller, interior magnet rotor, outer magnet rotor, separation sleeve, motor and hitch, and pump shaft is installed in the pump housing; Impeller is installed on the pump shaft; It is characterized in that said pump housing lagging is sheathed on the pump housing, offer steam in the pump housing lagging outside and import and export; Also be provided with bearing support between the pump housing and the hitch, said pump housing lagging and bearing support are double layer construction, and also offer steam in the outside of bearing support and import and export, and the steam (vapor) outlet on the bearing support is communicated with through pipeline with steam inlet on the pump housing lagging; This bearing support front end links to each other with the pump housing, and the rear end links to each other with hitch; Said outer magnet rotor is positioned at bearing support inside and links to each other with pump shaft, and it is inner that the front end of interior magnet rotor stretches into outer magnet rotor, and the rear end links to each other with motor shaft; Said separation sleeve be located at outer magnet rotor inner and interior magnet rotor and outside between the magnet rotor.
Pump housing outside is provided with lagging, and lagging and bearing support are two-layer, middle logical steam, better heat preservation.Internal rotor and external rotor have been changed the position, and internal rotor is installed on the motor, and it is inner that separation sleeve is positioned at outer magnet rotor, and all logical steam insulation in the whole bearing support, so whole overcurrent part can be accomplished all risk insurance temperature.
Compared with prior art, the advantage of the utility model is: adopt the magnetic force structure, can accomplish does not have leakage fully; Be that flow passage components are incubated fully, thus make medium in running or after shutting down all under keeping warm mode, be not incubated the dead angle fully, stopped because of the medium crystallization to the infringement that pump causes, make improve several times the working life of pump.
