Abstract
A lining fluorine magnetic drive pump comprises a pump body, a pump body inner lining, a pump shaft, a movable ring, a static ring, an impeller inner rotor, an outer magnetic rotor, an isolation sleeve, a connection frame and a motor, wherein the connection frame is connected between the pump body and the motor, the isolation sleeve is arranged between the impeller inner rotor and the outer magnetic rotor, and a bearing sleeve is sleeved on the pump shaft. The pump body inner lining, the impeller inner rotor and the isolation sleeve are made of pure F46 materials and formed by mould pressing in one time, and a reinforced cover made of polyphenylene sulfite (PPS) is attached to the outer side of the isolation sleeve. A spiral groove is arranged on the inner wall of the bearing sleeve, and one end face of the bearing sleeve is correspondingly provided with two radial grooves to be communicated with the spiral groove. Parts of the lining fluorine magnetic drive pump are high in hardness, abrasion-resistant and corrosion-resistant. The lining fluorine magnetic drive pump is suitable for conveying chemical liquid with high purity and corrosivity.
Description
Technical field
The utility model relates to a kind of driven pump, particularly a kind of lining fluorine magnetic drive pump.
Background technique
Because factors such as the fluoroplastic flowability is poor, difficult forming cause and produce very difficulty of fluoroplastic magnetic drive pump.Owing to need magnet steel in the setting-in on the impeller internal rotor; So general unit all adopts the quadric injection mould moulding process to make the impeller internal rotor; Cause the impeller internal rotor to have the secondary seam, so just adapted to not the severe corrosive operating mode, often have 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.And the rotating ring of magnetic drive pump 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 easy abrasion is cracked, and incompatibility highly corrosive, the more abominable occasion of operating mode; System pressure and ambient temperature can not be too high, otherwise head is divided very easily generation distortion.
The model utility content
The purpose of the utility model is to provide a kind of lining fluorine magnetic drive pump that adapts to the severe corrosive operating mode.
The purpose of the utility model is achieved in that a kind of lining fluorine magnetic drive pump; Comprise the pump housing, pump housing liner, pump shaft, rotating ring, stationary ring, impeller internal rotor, outer magnet rotor, separation sleeve, link press span and motor; Link press span is connected between the pump housing and the motor; Separation sleeve is arranged between impeller internal rotor and the outer magnet rotor, is with bearing housing on the pump shaft; Described pump housing liner, impeller internal rotor and separation sleeve all adopt pure F46 material one-step mould to form, and are fitted with the reinforcement cover that adopts PPS to process in the separation sleeve outside.
Described bearing housing inwall is provided with spiral chute, an end face correspondence of bearing housing be provided with two radially groove be communicated with above-mentioned spiral chute.
Described pump shaft, bearing housing, rotating ring and stationary ring all adopt pressureless sintering silicon carbide to be made.
Magnet steel in described impeller internal rotor and the outer magnet rotor is made by NdFeB material, and the magnetic intensity on magnet steel surface reaches 3600 Gausses.
Described link press span and terraced structure mutually nested link to each other of the pump housing through being provided with separately.
Described link press span comprises understructure.
The utility model has following advantage and characteristics owing to adopted above technological scheme:
1, pump housing liner, impeller internal rotor, separation sleeve all adopt pure F46 material one-step mould to form; Free from admixture is separated out, and is very suitable for the chemical liquid of delivery of high purity, highly corrosive;
2, pump shaft, bearing housing, rotating ring, stationary ring all adopt pressureless sintering silicon carbide, have characteristics such as high hardness, high abrasion, highly corrosion resistant;
3, the unique spiral chute design of bearing housing endoporus makes sliding bearing pair lubricated more convenient, fricative heat when taking away the pump running more easily;
4, 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;
5, internal-external magnetic steel is selected NdFeB material for use; Magnet steel Surface field intensity can pass to impeller to moment of torsion smoothly up to 3600 Gausses, and also can not skid in big flow operating mode; Can prevent that also the impeller internal rotor from contacting with the thrust ring of back, 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.
6, the entire pump group adopts the rear pull type structure, and a people just can carry out internal overhaul and part exchanging, and need not dismantle pipeline.
