Abstract
The utility model discloses a multitubular high-temperature magnetic pump applied to conveying petroleum and other high-temperature organic solvents, harmful and toxic high-temperature chemical mediumand other liquids, which comprises a pump body, an impeller, a pump shaft, a pump cover, an inner magnet and a suspension, wherein the pump shaft is fixed on the pump cover through a bearing and thepump body is fixed on the pump cover; one end of the pump shaft is fixed with the impeller and the other end of the pump shaft is fixed with the inner magnet; an isolating disk is arranged between thesuspension and the inner magnet, the pump cover is fixed with a cooling box sleeve, the suspension is fixed on the cooling box sleeve and at least four connecting pipes which are evenly distributed are arranged between the pump cover and the cooling box sleeve; and the pump cover is provided with at least one reverse tangential line water-out tank and other forward tangential line water-in tanks,and the water-in tanks and the water-out tanks are communicated with a connecting pipe to form a cooling loop. Through the forward tangential line water-in tanks and the reverse tangential line water-out tanks which are arranged on the pump cover and the rotation of the impeller, high-temperature liquid or medium automatically move in the cooling loop so as to achieve the function of cooling thepump shaft and to improve the service life of the pump shaft.
Description
Technical field:
The utility model relates to a kind of magnetic drive pump, relates in particular to be used in the High-temperature Magnetic Pump of high temperature organic solvent such as transfer oil and liquid such as high temperature is harmful, poisonous chemical mediator.
Background technique:
Existing High-temperature Magnetic Pump, the type of cooling is by changing the effect that pump cover or pump shaft reach cooling, but this mode, can make medium temperature own more and more higher, the condition and the cooling effect that have not only destroyed medium requirement itself are not obvious, also can cause the component Yin Gaowen of pump contact liq to produce thermal expansion, and be easy to wear, influence the overall performance of pump, serious meeting causes the magnet loss of excitation.
The another kind of type of cooling is by outside cooling cooling, and this type of cooling had both been wasted resource, increased energy consumption, can cause medium subcritical temperature again and crystallization, more can cause the parts wear at the running position of pump to be scrapped, thereby shorten working life, reduce productivity effect and corporate reputation.
The model utility content:
The utility model purpose is to provide a kind of and turns round steadily, mechanical property is remarkable, long service life, cooling, extraordinary multi-tube High-temperature Magnetic Pump that self-lubricating effect is good.
The utility model is achieved in that a kind of multi-tube High-temperature Magnetic Pump, comprise the pump housing, impeller, pump shaft, pump cover, inner magnet and suspension, described pump shaft by bearing fixing on described pump cover, the described pump housing is fixed on the described pump cover, described pump shaft one end is fixed with described impeller, its the other end is fixed with described inner magnet, between described suspension and inner magnet, be provided with separator, it is characterized in that: on described pump cover, be fixed with the cooling housing-case, described suspension is fixed on described cooler bin and puts, between described pump cover and cooling housing-case, be provided with equally distributed at least four connecting tubes, described pump cover is provided with at least one reverse tangent line effluent trough, all the other are forward tangent line intake chamber, described intake chamber and the effluent trough formation cooling circuit that communicates with described connecting tube.
According to the big or small radical of determining connecting tube of technical data required for the pump, when described connecting tube was the six roots of sensation, intake chamber was four on the described pump cover, and effluent trough is two.
When described connecting tube was eight, intake chamber was six on the described pump cover, and effluent trough is two.
Be provided with separator between described pump cover and cooling casing, described separator is provided with cooling water outlet and inlet.
The utility model compared with prior art has following advantage:
Since in course of conveying the temperature of pump shaft much larger than the temperature of high-temp liquid or medium, therefore by the forward tangent line intake chamber on the pump cover, the oppositely rotation of tangent line effluent trough and impeller, high-temp liquid or medium are moved in cooling circuit automatically, reach the effect of cooling pump shaft.
2. be provided with separator at pump cover and cooling between the housing-case, and separator is provided with the import and export of cooling water,, further reduces the temperature of pump shaft, improve the working life of pump shaft by the effect of cooling water.
