In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Fig. 1 is a schematic structural diagram of a hydrogen gas circulation pump used in a hydrogen fuel cell system according to an embodiment of the present invention.

The magnetic connection structure 3 comprises a first magnetic member 31, a magnetically permeable and magnetically permeable spacer 32 and a second magnetic member 33. Wherein the first magnetic member 31 is connected with the first cam shaft 213. The second magnetic member 33 is connected to the driving end 11 of the motor 1, and the second magnetic member 33 is disposed opposite to the first magnetic member 31. The magnetic conduction and conduction isolating piece 32 is hermetically connected with the pump body 2 and used for isolating the first magnetic piece 31 from the second magnetic piece 33.
In this embodiment, the first magnetic member 31 and the second magnetic member 33 have the same magnetic pole, and the first magnetic member 31 and the second magnetic member 33 rotate synchronously under the action of the repulsive force; alternatively, the first magnetic member 31 and the second magnetic member 33 have different magnetic poles, and the first magnetic member 31 and the second magnetic member 33 rotate synchronously by the action of a gravitational force.
In specific implementation, if the magnetic poles of the first magnetic member 31 and the second magnetic member 33 are the same, the working process of the hydrogen circulation pump is as follows: when the motor 1 works, the driving end 11 of the motor 1 rotates to drive the second magnetic part 33 connected with the driving end 11 to rotate, the second magnetic part 33 gives repulsive force to the first magnetic part 31, and under the action of the repulsive force, the first magnetic part 31 also rotates along with the second magnetic part 33, so that the first cam shaft 213 connected with the first magnetic part 31 is driven to rotate; if the magnetic poles of the first magnetic member 31 and the second magnetic member 33 are different, the working process of the hydrogen circulation pump is as follows: when the motor 1 works, the driving end 11 of the motor 1 rotates to drive the second magnetic member 33 connected with the driving end 11 to rotate, the second magnetic member 33 gives an attractive force to the first magnetic member 31, and under the action of the attractive force, the first magnetic member 31 also rotates along with the second magnetic member 33, so that the first cam shaft 213 connected with the first magnetic member 31 is driven to rotate. No matter the magnetic poles of the first magnetic member 31 and the second magnetic member 33 are the same, or the magnetic poles of the first magnetic member 31 and the second magnetic member 33 are different, when the driving end 11 of the motor 1 drives the first cam shaft 213 to rotate, the magnetic conductive isolator 32 keeps the first magnetic member 31 and the second magnetic member 33 isolated and simultaneously keeps the seal with the pump body 2, so that the hydrogen gas in the pump body 2 is effectively prevented from leaking, and the sealing performance is good.

The material has the characteristics of acid resistance, alkali resistance and various organic solvents resistance, and is almost insoluble in all solvents. Meanwhile, the polytetrafluoroethylene has the characteristic of high temperature resistance, and the friction coefficient of the polytetrafluoroethylene is extremely low.
Therefore, among the prior art, hydrogen circulating pump drive gear needs the oil bath lubrication, and when the hydrogen circulating pump was rotatory at high speed, the lubricating grease can volatilize, had polluted the phenomenon of the hydrogen of carrying. First gear 211 of this application embodiment with second gear 221 is made by polyether ether ketone or polytetrafluoroethylene material, and first gear 211 also can realize the self-lubricating with second gear 221 even when the rotational speed is 7000rpm, has better mechanical properties and self-lubricating property to eliminate among the prior art the pollution of lubricating medium high temperature volatilization to hydrogen, and then the effectual life who prolongs hydrogen fuel cell.

The second cam 222 and the second gear 221 are provided on the second cam shaft 223 to rotate coaxially with the second cam shaft 223. The first gear 211 and the first cam 212 are driven to rotate by the first cam shaft 213, so that the first gear 211 drives the second gear 221 to rotate, and the second gear 221 drives the second cam shaft 223 to rotate so as to drive the second cam 222 to rotate. The first cam 212 and the second cam 222 are both in an 8-shaped structure, and the concave part of the first cam 212 is opposite to the convex part of the second cam 222.
According to the embodiment of the invention, the first cam and the second cam are arranged close to the driving end of the motor, and the first gear and the second gear are arranged far away from the driving end of the motor, so that the first cam and the second cam with large rotation fluctuation are positioned at the gravity center position of the hydrogen circulating pump, the shaking is effectively prevented, and the hydrogen circulating pump is stable in the working process.
According to the hydrogen circulating pump provided by the invention, the magnetic conductive isolating piece is hermetically connected with the pump body and isolates the first magnetic piece and the second magnetic piece, so that the first cam shaft connected with the first magnetic piece is separated from the driving end connected with the second magnetic piece. When the motor works, the driving end of the motor drives the first cam shaft to rotate through the magnetic force between the second magnetic piece and the first magnetic piece. Compared with the prior art, the phenomenon that the hydrogen leaks due to the fact that the sealing element is damaged due to the fact that the transmission shaft rubs with the sealing element in the rotating process is avoided, the sealing performance of the hydrogen is effectively improved, and safety is high.
