Abstract

The utility model relates to a novel fluorine lined magnetic drive pump, which comprises a pump body (1), a stationary ring (2), a movable ring (3), an inner impeller rotor (4), an isolating sleeve (5), a bearing sleeve (6), a pump shaft (7), a rear thrust ring (8), a reinforcing cover (9), an outer magnetic rotor (10) and a connecting frame (11). The novel fluorine lined magnetic drive pump is characterized in that a pump body lining, the inner impeller rotor and the isolating sleeve are made of pure F46 materials in a one-step mould pressing manner, an outer casing of the pump body is made of modular cast iron, the pump shaft, the bearing sleeve, the stationary ring and the movable ring are made of pressureless sintering silicon carbide, a helical groove is arranged in an inner hole of the bearing sleeve, the reinforcing cover made of PPS (polyphenylene sulfite) is additionally arranged outside the isolating sleeve, and an inner magnet and an outer magnet are made of neodymium iron boron materials. The novel fluorine lined magnetic drive pump has the advantages that the magnetic drive pump can work normally in high-corrosive places, the integral pump is in a rear drawing structure, interior maintenance and replacement of parts can be carried out by a single person and detachment of pipelines is omitted.

Description

Novel lining fluorine magnetic force driving pump

Technical field

The utility model relates to a kind of pump of carrying liquid, is specifically related to a kind of pump of carrying inflammable, explosive, poisonous, harmful liquid, promptly novel lining fluorine magnetic force driving pump.

Background technique

The pump housing of traditional nonmetal magnetic drive pump, impeller, separation sleeve generally all adopt polypropylene injection molded, and impeller is because there is interior magnet steel must adopt the quadric injection mould moulding process, do not adapt to the severe corrosive operating mode like this, often there is medium in the seam of the quadric injection mould of impeller, to infilter interior magnet steel, the impeller internal rotor is swollen, cause a series of serious consequence thereby burst separation sleeve.Rotating ring and axle sleeve are generally all selected carbon graphite material for use, and stationary ring and pump shaft are selected alumina ceramics for use, and this configuration wearing and tearing easily is cracked, and incompatibility highly corrosive occasion, and system pressure and ambient temperature can not be too high, otherwise head is divided very easily generation distortion.In order to address the above problem, the utility model improves former magnetic drive pump, satisfies in the productive life needs to magnetic drive pump.

The model utility content

The utility model is at the above-mentioned shortcoming of prior art, provides that a kind of serviceable bife is long, intensity is high, the novel easily lining fluorine magnetic force driving pump of maintenance.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of novel lining fluorine magnetic force driving pump, comprise the pump housing (1), stationary ring (2), rotating ring (3), impeller internal rotor (4), separation sleeve (5), bearing housing (6), pump shaft (7), back thrust ring (8), reinforcement cover (9), outer magnet rotor (10), link press span (11), outer magnet rotor and interior magnet rotor are provided with some to magnet, and separation sleeve is located between outer magnet rotor and the interior magnet rotor.It is characterized in that: pump housing liner, impeller internal rotor, separation sleeve all adopt pure F46 material one-step mould to form; Pump housing shell adopts spheroidal graphite cast iron; Pump shaft, bearing housing, dynamic and static ring all adopt pressureless sintering silicon carbide, the bearing housing endoporus is ad hoc spiral chute, and employing reinforcement cover, inside and outside magnetic separation NdFeB material have been set up in the separation sleeve outside.

The utlity model has following advantage: (1) pump housing liner, impeller internal rotor, separation sleeve all adopt pure F46 material one-step mould to form, and free from admixture is separated out, and is very suitable for the chemical liquid of delivery of high purity, highly corrosive; (2) pump housing shell adopts spheroidal graphite cast iron can increase the intensity and the serviceability of pump; (3) pump shaft, bearing housing, dynamic and static ring all adopt pressureless sintering silicon carbide, have characteristics such as high hardness, high abrasion, highly corrosion resistant; (4) spiral chute of bearing housing endoporus uniqueness design makes sliding bearing pair lubricated more convenient, easier fricative heat when taking away the pump running; (5) the separation sleeve outside has been set up and has been adopted the special reinforcement cover that forms of imported materials PPS, makes the pump group can bear higher system pressure, and can eliminate the heat that adopts metallic sheath to produce because of the magnetic eddy current; (6) inside and outside magnetic separation NdFeB material, the magnet steel surface is up to 3600 Gausses, can pass to impeller to the moment of torsion of prime mover smoothly, and can not skid in big flow operating mode yet and can prevent that the impeller internal rotor from contacting with back thrust ring yet, thereby prevent to melt the fluoroplastic parts, guarantee that magnetic drive pump can normally move in the occasion of severe corrosive because of frictional heating; (7) the entire pump group adopts the rear pull type structure, and a people just can carry out internal overhaul and part exchanging, and does not need to dismantle pipeline.

Embodiment

A kind of as shown in Figure 1 novel lining fluorine magnetic force driving pump comprises the pump housing 1, stationary ring 2, rotating ring 3, impeller internal rotor 4, separation sleeve 5, bearing housing 6, pump shaft 7, back thrust ring 8, reinforcement cover 9, outer magnet rotor 10, link press span 11.Pump housing liner, impeller internal rotor 4, separation sleeve 5 all adopts pure F46 material one-step mould to form, motor shaft is fixedlyed connected with outer magnet rotor 10 bottom center, stationary ring 2 is pressed into the pump housing 1 import position, pump shaft 7 one ends are positioned in stationary ring 2 center holes, one end is processed into the square square hole in the separation sleeve 6 that is pressed into, in the impeller internal rotor 4 with bearing housing 6 close-fittings, impeller internal rotor 4 can easily rotate on pump shaft 7 simultaneously with bearing housing 6, the impeller internal rotor is dissolved in the outer magnet rotor, and with outer magnet rotor arranged concentric, establish separation sleeve 5 and reinforcement cover 9 between impeller internal rotor and the outer magnet rotor, the sealing of separation sleeve 5 and the pump housing 1 is connected with the pump housing 1 to reach after fastening by link press span 11 and compresses sealing.

During work, the outer magnet rotor 10 of driven by motor rotates, because the magnetic pull effect, impeller internal rotor 4 is driven, wheel rotation, pump working.And bearing housing 6 endoporus are provided with unique helical groove structure, it is enough lubricated and be with heat that sliding bearing pair is obtained, separation sleeve 5 outsides have been set up and have been adopted the special reinforcement cover 9 that forms of imported materials PPS, make the pump group can bear higher system pressure, and can eliminate the heat that adopts metallic sheath to produce because of the magnetic eddy current; Inside and outside magnetic separation NdFeB material, the magnet steel surface is up to 3600 Gausses, can pass to impeller to the moment of torsion of prime mover smoothly, and also can not skid in big flow operating mode and can prevent that also impeller internal rotor 4 from contacting with back thrust ring 8, thereby prevent to melt the fluoroplastic parts because of frictional heating; Guarantee that magnetic drive pump can normally move in the occasion of severe corrosive; The entire pump group adopts the rear pull type structure, and a people just can carry out internal overhaul and part exchanging, and does not need to dismantle pipeline.
