Description

A magnetically suspended centrifugal blower

Technical Field

The utility model relates to the technical field of blowers, in particular to a magnetic suspension centrifugal blower.

Background Art

A magnetic levitation blower is a fan that uses magnetic levitation technology to support and rotate the blower impeller. This technology suspends the blower impeller through a magnetic field, avoiding direct mechanical contact, reducing wear and energy loss. This type of fan is commonly used in ventilation, gas transportation and other fields in industrial production.

However, when some existing magnetic levitation centrifugal blowers are placed for a long time, dust may enter the interior of the blower due to the presence of heat dissipation holes. Dust accumulates on the fan blades or other mechanical parts inside the blower, which increases aerodynamic resistance, reduces the efficiency of the blower, and causes damage to the blower output. Secondly, the magnetic levitation centrifugal blower itself may also be heavy, which makes it difficult to carry and move. After searching, it was found that the technical solution provided by the utility model with application number CN202120483165.4 also has the above-mentioned problems.
