Abstract

The invention relates to a full-sealed leakage-free magnetic drive hydrogen circulating pump. The hydrogen circulating pump comprises a motor cavity and a pump shell; a sealing partition plate is arranged between the motor cavity and the pump shell; a stator winding is fixedly installed in the motor cavity; an impeller is rotationally installed in the pump shell; a permanent magnet rotor is fixedly inlaid in the surface of the impeller; an iron core and a coil of the stator winding are designed in a plane mode; the magnetic field plane of the stator winding faces the permanent magnet rotor on the plane of the impeller; the stator winding generates a magnetic field to drive the permanent magnet rotor to drive the impeller to rotate; and the pump shell is provided with a gas inlet and a gas outlet. The hydrogen circulating pump can effectively prevent a medium from containing oil, a motor stator and the motor permanent magnet rotor are sealed and isolated, the permanent magnet rotor and the impeller are integrated, the medium is completely sealed, medium leakage is completely avoided, and potential safety hazards are avoided.

Description

technical field [0001] The invention relates to a fully-sealed and leak-free magnetic drive hydrogen circulation pump, which belongs to the technical field of hydrogen fuel cells. Background technique [0002] Hydrogen fuel cells use the chemical reaction of hydrogen and oxygen to generate current and water, which is not only completely pollution-free, but also avoids the time-consuming problem of traditional battery charging. It is currently the most promising new energy method. If it can be popularized and applied in Vehicles and other highly polluting power generation tools will significantly reduce air pollution and the greenhouse effect. Hydrogen fuel cells require that the supplied gas be clean and oil-free, and at the same time, considering the flammable and explosive characteristics of the conveying medium, it also has high requirements on the leakage prevention of the supply system; [0003] Conventional circulating pumps are equipped with oil cavity lubrication, w...
