[0008] Specific implementation mode two: as Figure 1~2 As shown, the coiled pipe 3 in this embodiment is made of glass. With such a design, the coil pipe 3 can function as a magnetic isolation. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0009] Specific implementation mode three: as Figure 1~2 As shown, the coiled pipe 3 in this embodiment is made of plastic. With such a design, the coil pipe 3 can function as a magnetic isolation. Other components and connections are the same as those in the first embodiment.

[0010] working principle:

[0011] According to fluid dynamics and electromagnetic field theory, an inner rotor rotating magnetic fluid traveling wave pump is designed. After the coil 3 is filled with magnetic fluid, install the first non-magnetic shaft 1-1 and the second non-magnetic shaft 4-2 of the inner rotor rotating type magnetic fluid traveling wave pump on the non-magnetic bracket, and use external force or The motor drives the rotor 4 to rotate. Since the permanent magnet 2 is fixedly sleeved on the rotor 4 , the permanent magnet 2 is driven to rotate together with the rotor 4 . The rotating permanent magnet 2 forms a rotating magnetic field between the rotor 4 and the stator 1 . The magn...

Abstract

The invention discloses an inner-rotor rotary magnetic fluid traveling wave pump, which relates to a magnetic fluid traveling wave pump. The invention solves a problem that at present, no inner-rotor rotary magnetic fluid traveling wave pump for analyzing the motion law of magnetic fluid in a traveling wave magnetic field is available. A pipe coil is arranged in a cylinder body, the two ends of the pipe coil pass through the through holes on the cylinder body respectively, a rotor consists of a magnetic iron core and a second non-magnetic shaft, the magnetic iron core is fixedly arranged on the second non-magnetic shaft, a permanent magnet is sleeved on the magnetic iron core, the permanent magnet consists of a plurality of permanent magnet single bodies which magnetize axially, the magnetizing directions of two adjacent permanent magnet single bodies are opposite, both the magnetic iron core and the permanent magnet are arranged in the cylinder body, a gap is reserved between the permanent magnet and the pipe coil, and the pipe coil is made of a non-magnetic conductive material. Based on the dynamic principles of the magnetic fluid, the invention provides the inner-rotor rotary magnetic fluid traveling wave pump. In the invention, the transport characteristics of the magnetic fluid can be proved, so a new application area is created for the magnetic fluid.
