Heavy-load fluorine lined magnetic force pump

Abstract

The invention provides a heavy-load fluorine lined magnetic force pump. The heavy-load fluorine lined magnetic force pump comprises a pump body, an impeller, an intermediate body, a pump shaft, an internal magnet rotor assembly, a spacer sleeve assembly, an external magnet rotor assembly and a connecting frame, wherein a reinforced iron frame is arranged in the impeller; the spacer sleeve assemblyis formed by overlapping an inner sleeve and a lining reinforced outer sleeve; the impeller and the internal magnet rotor assembly are mounted at the two ends of the pump shaft correspondingly; a thrust collar, a shaft sleeve and a retaining sleeve are arranged in the middle portion of the pump shaft. The heavy-load fluorine lined magnetic force pump further comprises the intermediate body arranged independently. A bearing sleeve is mounted on the intermediate body. The heavy-load fluorine lined magnetic force pump has the advantages of being high in mechanical strength, safe, reliable, morestable in operation, reasonable in circulation, high in pump efficiency, wide in application range and the like.

Description

technical field [0001] The invention relates to a pump, in particular to a heavy-duty fluorine-lined magnetic drive pump. Background technique [0002] At present, fluorine-lined magnetic pumps are widely used in the transportation of liquid media that are highly corrosive and do not allow leakage. The overall structure of the pump is very simple. The shaft sleeve is pressed into the inner hole, and then installed on the SSiC pump shaft fixed at both ends through the shaft sleeve; when the pump body lining is pressed, a fluoroplastic seat is preset at the inlet, and the rear end of the fluoroplastic inner sleeve of the isolation sleeve is provided with fluorine Plastic seat, both ends of the pump shaft are fixed on the inlet of the pump body and the fluoroplastic seat of the fluoroplastic inner sleeve. When the fluorine-lined magnetic drive pump is in normal operation, the pump shaft only supports the inner rotor assembly and does not rotate with the inner rotor assembly. ,...

[0002] At present, fluorine-lined magnetic pumps are widely used in the transportation of liquid media that are highly corrosive and do not allow leakage. The overall structure of the pump is very simple. The shaft sleeve is pressed into the inner hole, and then installed on the SSiC pump shaft fixed at both ends through the shaft sleeve; when the pump body lining is pressed, a fluoroplastic seat is preset at the inlet, and the rear end of the fluoroplastic inner sleeve of the isolation sleeve is provided with fluorine Plastic seat, both ends of the pump shaft are fixed on the inlet of the pump body and the fluoroplastic seat of the fluoroplastic inner sleeve. When the fluorine-lined magnetic drive pump is in normal operation, the pump shaft only supports the inner rotor assembly and does not rotate with the inner rotor assembly. , due to the lack of mechanical strength of this structure, it is often suitable for the transmission process conditions of strong corrosive media with low flow rate and lift power, and in the transmission process conditions of strong corrosive liquids that require large flow rate, high lift and high power, the fluorine-lined magnetic pump and not well promoted
