The implementation principle of the high-purity gas supercharging device provided by the embodiment of the application is as follows: when the supercharging device is used for supercharging high-purity gas, the driving assembly 5 is used for driving the outer magnet 4 to reciprocate along the central axis of the cylinder sleeve 2, the magnetic force of the outer magnet 4 drives the magnetic piston 3 to reciprocate in the cylinder sleeve 2, the high-purity gas passes through the air inlet check valve 9 along the air inlet pipeline 11 and enters the cylinder sleeve 2 through the air inlet hole 7, and after being compressed by the magnetic piston 3, the high-purity gas passes through the air outlet check valve 10 through the air outlet hole 8 and flows out along the air outlet pipeline 12, so that the supercharging of the high-purity gas is realized.
Through setting up magnetism piston 3 and overcoat at the cylinder body in cylinder liner 2 and establishing outer magnet 4, utilize drive assembly 5 to drive the reciprocating motion of outer magnet 4 along cylinder liner 2 axis, outer magnet 4 magnetic force drive magnetism piston 3 moves in cylinder liner 2 for outer magnet 4 is exerted force acting on magnetism piston 3 all the time, realizes the pressure boost to the interior high purity gas of cylinder liner 2, has improved the problem that the driver can't exert force acting on the permanent magnet piston all the time. Through the outer wall of sealing washer 34 expands outward and sets up sealing ring 14 that polytetrafluoroethylene made, when sealing ring 14 receives high-purity gas pressure or the butt of butt joint board 15 expands the external force, the cross-section diameter of sealing ring 14 enlarges for sealing ring 14 pastes tightly on the inner wall of cylinder liner 2, has strengthened sealing ring 14's sealed effect, reduces the risk that gas flows out at the gap between magnetism piston 3 and cylinder liner 2, improves supercharging device's supercharging effect to gas.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
