Description

Technical Field

[0001] The present application relates to the field of magnetic pumps, and in particular to a noise reduction housing device for a magnetic pump. Background Art

[0002] Magnetic pump is a branch of the water pump field. It is a new product that applies the working principle of permanent magnetic coupling to centrifugal pump. Magnetic pump is divided into AC micro, brushed DC, brushless DC and other types. It has the characteristics of full sealing, no leakage, corrosion resistance, etc. It consists of three parts: pump, magnetic transmission and motor. The magnetic transmission of magnetic pump consists of outer magnetic rotor, inner magnetic rotor and non-magnetic isolation sleeve. When the motor drives the outer magnetic rotor to rotate, the magnetic field can penetrate the air gap and non-magnetic materials, drive the inner magnetic rotor connected to the impeller to rotate synchronously, realize the contactless synchronous transmission of power, and transform the dynamic sealing structure that is prone to leakage into a static sealing structure with zero leakage.

[0003] Since the pump shaft and the inner magnetic rotor are completely enclosed by the pump body and the isolation sleeve, the problems of "escape, bubbling, dripping and leakage" are completely solved. The use of magnetic pumps has spread to various fields. However, since the magnetic pump makes noise when in use, it affects the work of workers near the magnetic pump station, and the noise generated by the magnetic pump will cause environmental sound pollution.
