Magnetic drive pump with improved structure

Abstract

The invention discloses a magnetic drive pump with an improved structure. The magnetic drive pump comprises a magnetic drive pump body, an outer shell arranged on the outer side of a pump body of the magnetic drive pump body, and a liquid inlet pipe arranged on the outer shell. The output end of the pump body of the magnetic drive pump body is connected with a liquid outlet pipe, and the liquid outlet pipe penetrates through the outer shell. The end, which penetrates through the outer shell and is close to the magnetic drive pump body, of the liquid inlet pipe is connected with a water flow distribution device which is used for discharging media entering the outer shell in a surrounding mode and assisting in removing impurities adhering to the outer shell. According to the magnetic drive pump with the improved structure, the water flow distribution device is arranged at the end, close to the magnetic drive pump body, in the outer shell, and the water flow distribution device can discharge high-corrosion media such as liquid chlorine in the outer shell in the shape of threads; and in the discharging process, on the one hand, the impurities remaining on the inner wall of the outer shell can be taken out, meanwhile, the flow of the media in the outer shell is increased, the impact force between the media and the outer shell is reduced, and the effect of further scraping the impurities on the inner wall of the outer shell is achieved.

Description

technical field [0001] The invention relates to the technical field, in particular to a magnetic pump with improved structure. Background technique [0002] Magnetic pump (also known as magnetic drive pump) is mainly composed of pump head, magnetic drive (magnetic cylinder), motor, base and other parts. The magnetic drive of the magnetic pump is composed of an outer magnetic rotor, an inner magnetic rotor and a non-magnetic isolation sleeve. When the motor drives the outer magnetic rotor to rotate through the coupling, the magnetic field can penetrate the air gap and the non-magnetic material isolation sleeve, and drive the inner magnetic rotor connected to the impeller to rotate synchronously, realizing the non-contact synchronous transmission of power, and will easily leak The dynamic seal structure is transformed into a static seal structure with zero leakage. Since the pump shaft and inner magnetic rotor are completely sealed by the pump body and the isolation sleeve, ...

Problems solved by technology

[0003] At present, when the existing magnetic pump transports highly hazardous media, such as liquid chlorine, it has the performance of being highly toxic, highly corrosive, highly permeable, and moisture-absorbing. Due to the characteristics of magnetic pumps, it cannot achieve continuous stability and high-pressure resistance. Although the existing magnetic pumps with multi-stage two-way casings can transport highly hazardous media such as liquid chlorine, that is, when liquid chlorine is transported, the liquid chlorine It can fill the entire inner magnetic rotor and the pump chamber, and the liquid chlorine flows inside the cavity between the inner magnetic rotor and the isolation sleeve, taking away the heat generated by the eddy current and preventing mechanical cavitation of the liquid chlorine, but through the medium at the bottom of the outer shell When the liquid chlorine is discharged into the inlet, it will cause a large impact force to be discharged into the liquid chlorine, resulting in an increase in the vibration force between the outer shell and the inner shell, further increasing the phenomenon of shell damage, and at the same time due to the liquid chlorine There are more residues in it, so more residues are easy to remain on the inner wall of the shell, which further affects the transportation of liquid chlorine. Therefore, we propose a magnetic pump with improved structure
