Abstract

The invention provides a magnetic suspension air blower and a ventilation system and belongs to the field of air blowers. The air blower mainly comprises a spindle, a permanent magnetic motor, a machine case, a transformer and a voltage regulation device. The spindle passes through a radial bearing, a first axial bearing and a second axial bearing to be connected with a supporting structure in themachine case in a matched mode. The end of the spindle is provided with an impeller. The permanent magnetic motor drives the spindle and the impeller to rotate synchronously. Magnetic suspension bearings are adopted as the radial bearing, the first axial bearing and the second axial bearing. The transformer is electrically connected with the second axial bearing and used for supplying electric energy to the second axial bearing. The voltage regulation device is used for regulating output voltage of the transformer. The output voltage can be dynamically regulated in real time according to themagnitude of axial force. The friction force of the spindle can be prevented from increasing along with increasing of the rotational speed. Compared with a magnetic suspension air blower which can directly supply large output voltage, the magnetic suspension air blower provided by the invention can save electric energy.

Description

technical field [0001] The invention relates to the field of blowers, in particular to a magnetic levitation blower and a ventilation system. Background technique [0002] The blower is a device that uses the rotation of the impeller to discharge the air in the casing through the air outlet pipe, so that negative pressure is generated in the casing, and the negative pressure sucks in air, and then the air is discharged through the air outlet pipe through the rotation of the impeller. Driven by the permanent magnet motor, the main shaft rotates together with the impeller, because the air flow is sucked in from the end of the impeller, and the flow speed is fast; this makes the main shaft bear both radial force and axial force. Therefore, the connection between the main shaft and the casing requires radial bearings and axial bearings to bear radial force and axial force respectively. [0003] In order to reduce the friction between the main shaft and the bearing, some blowers...
