Abstract
The utility model discloses a magnetic driving pump, comprising a bracket, a pump axis, a blade wheel, a back cover, an abrasion-proof impeller ring, an outer magnet steel, an inner magnet steel, a rotor, a metal separation sleeve and a fluorineplastic separation sleeve. An inner magnet steel rotor insert and an impeller axis are an integral structure, and the back cover of the pump is provided with a single sliding bearing. The utility model is characterized in that the magnetic driving pump is of long service life, corrosion prevention and leaktightness, being suitable for the chemical industry field.
Description
Technical field
The utility model relates to a kind of magnetic force driving pump, especially is applicable to the magnetic force driving pump of chemical field.
Background technique
Existing magnetic force driving pump mainly by the outer steel in the pump housing, the magnetic effect effect of interior magnet steel, drives pump shaft, and then the impeller rotary work.Because multiple spot bearings before, during and after pump shaft adopts is long partially with the distance of impeller, cause the multiple spot friction, the pump running is uneven, noise is big, working life is short thereby cause.In addition, traditional magnetic force driving pump rotor shaft mostly is stupalith and makes, and frangible, rapid wear, is subject to the service condition restriction of chemical mediator.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of long service life, anticorrosion, leak free magnetic force driving pump are provided.
Magnetic force driving pump of the present utility model, comprise support, pump shaft, impeller, bonnet, wear-resisting choma, outer steel, interior magnet steel, rotor, metal separation sleeve, fluoroplastic separation sleeve, magnet steel rotor inserts and impeller shaft are structure as a whole in described, and described pump postoperculum is equipped with single sliding bearing.
Described single sliding bearing is made by pressureless sintering silicon carbide.
Described pump shaft rotor adopts alloyed steel outsourcing fluoroplastic to make.
The beneficial effects of the utility model are: interior magnet steel rotor inserts and impeller shaft are structure as a whole, the pump machine is when work, have only pump postoperculum that single sliding bearing and single end face point of contact of interior magnet steel rotor are housed, thereby, solved widely that the pump shaft in the traditional type is frangible, rapid wear, be subject to the shortcoming that the service condition restriction of chemical mediator exists, simultaneously, also shortened the distance between axle and the impeller, reliable performance safety, long service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Among the figure: 1. pump case 2. impellers 3. bonnets 4. plastic barrier are overlapped magnet steel 8. supports 9. outer steels 10. motors in pump shaft 5. metal separation sleeves 6. single sliding bearings 7.
Embodiment
The utility model magnetic force driving pump is connected the pump case (1) that support (8) is made by direct fixedly fluoroplastic mold pressing on the support again by motor (10), rotate by the direct transmission outer steel of motor shaft (9), according to magnetic effect, magnet steel rotating shaft (7) in driving, in order to prevent that chemical mediator from contacting with outer steel, fluoroplastic separation sleeve (4), metal separation sleeve (5) are housed in interior magnet steel rotating shaft and outer steel, support interior magnet steel rotating shaft by the single sliding bearing (6) in the bonnet (3), impeller (2) connects with interior magnet steel rotating shaft silking.Interior magnet steel rotor inserts and impeller shaft outsourcing fluoroplastic are made integral type; support impeller shaft; the sliding shaft sleeve of being made by PTFE is filled in the outsourcing of impeller shaft; single sliding bearing can select for use pressureless sintering silicon carbide to make; the pump shaft rotor adopts alloyed steel outsourcing fluoroplastic to make; they all are a kind of corrosion resistant, high-abrasive material, play buffering, damping effect in this pump starting, a moment of shutting down or operation process.
Claims (3)
1, a kind of magnetic force driving pump, comprise support, pump shaft, impeller, bonnet, wear-resisting choma, outer steel, interior magnet steel, rotor, metal separation sleeve, fluoroplastic separation sleeve, it is characterized in that: magnet steel rotor inserts and impeller shaft are structure as a whole in described, and described pump postoperculum is equipped with single sliding bearing.
2, magnetic force driving pump according to claim 1 is characterized in that: described single sliding bearing is made by pressureless sintering silicon carbide.
