Description

[0002] At present, there are many types of pressure pumps, such as gear pumps, vane pumps, plunger pumps, etc. in hydraulic pumps, and there are also many magnetic pumps for corrosive media. The plunger pump uses the relative reciprocating motion of the piston and the cylinder to cause the closed working chamber in the pump to change its volume to achieve the suction and pressure of the fluid. However, since the reciprocating motion of the plunger pump is converted from the rotational motion, its structure is complex, the manufacturing cost is high, and the energy consumption and noise are relatively large. The magnetically driven fluid pump relies on the driving of the changing magnetic field, and its stroke and stop point can be controlled by magnetic force and program. It has a compact structure and higher efficiency. However, the essence of the existing magnetically driven fluid pump is to drive the fluid to move by pressure. This method is inefficient and cannot control the movement of the magnetic fluid by electromagnetic force to form a vortex to achieve the purpose of extracting the fluid. Therefore, it is necessary to invent a magnetic fluid vortex pump to solve the above problems. Summary of the invention
