Abstract
This invention discloses a magnetically levitated centrifugal fan of high electro motion, which includes: the shell of the electric motor in which there is the first radial axletree, the stator of the motor, the second radial axletree, the first thrust axletree and the second thrust axletree; the shell is connected with a turbine through back tray, a main axis is set on the central axes in the space of the shell, on the main axis there is orderly the rotor of the motor matched with the motor stator, the thrust disk and the impeller; the impeller is in the eddy shell on which the axes-directed air input and the radial directed air output are equipped. This invention use the design of coaxal motor rotor and the thrust disk, the radial axletree and the thrust axletree adopt magnetic levitated axletree or air axletree. This invention has high speed, small cubage, light weight, large flux, high efficiency, convenient charge adjustment and non-pollution.
Description
technical field [0001] The invention belongs to the fields of petroleum, chemical industry, metallurgy and environmental protection, and relates to a blower, in particular to a high-speed electric magnetic suspension centrifugal blower. Background technique [0002] Fan, according to the size of its outlet pressure, it can be divided into ventilator, blower and compressor (or compressor). As the name suggests, it is used as a ventilation / air supply mechanical equipment, which is widely used in various industries, especially in petroleum, chemical industry, metallurgy, aviation, aerospace, environmental protection and other fields. At the same time, it also occupies a very important position in all walks of life, and its role is irreplaceable. However, the current fan products generally have problems such as small capacity, low efficiency, high noise, small performance adjustment range, and high operation and maintenance costs. Among them, fan efficiency is the most importan...
