The damping piston 10 is provided with a ring groove on the outer wall of one end of the damping sleeve 8, and a sealing ring 9 is embedded in the ring groove. The damping device 100 also has a damping effect, when the damping piston 10 descends, pressure is applied to the cavity at the upper part of the damping sleeve 8, the cavity at the upper part of the damping sleeve 8 applies pressure to the damping liquid, and then the damping liquid compresses the air in the pressure chamber until the damping piston 10 no longer descends, and the damping purpose is achieved due to the compression buffer of the air.

[0033] The working principle of the damping mechanism of the air magnetic suspension centrifugal blower is as follows:

[0034] When the air magnetic suspension centrifugal blower works and generates vibration, the mounting plate 2 will vibrate. The spring 4 first plays a buffering role and absorbs part of the vibration energy through elastic deformation. At the same time, the vibration of the mounting plate 2 drives the damping piston 10 to slide up and down in the damping sleeve 8, the damping liquid flows to generate damping force, further consumes vibration energy, and thus effectively suppresses the vibration of the blower. The guide rod 3 in the guide assembly slides in the guide hole, which can ensure the stability of the mounting plate during vibration and prevent the mounting plate from deviating. The anti-skid pads 6 at the bottom of the base 5 can increase the friction force between the whole damping mechanism and the placement surface, and prevent the damping mechanism from moving during work.

[0035] In conclusion, the utility model discloses a double damping effect through the cooperation of damping spring and damping sleeve, can effectively reduce the vibration of air magnetic suspension centrifugal blower when working, improves the stability and service life of blower.
