Magnetic levitation centrifugal blower is a type of fan. It is a new type of blower that integrates magnetic levitation technology and high-speed motor technology into traditional fans to form a high-efficiency, energy-saving and environmentally friendly blower. It is widely used Used in ventilation of factories, mines, tunnels, etc.; urban sewage treatment; wind tunnel wind sources and other industrial projects.
Instrument features:
Small size, high power, high efficiency, simple structure, energy saving and environmental protection; magnetic levitation technology and high-speed motor technology are added to the traditional fan structure.
Principle and composition:
The magnetic levitation centrifugal blower is an electromechanical integration product. It mainly consists of three parts: the magnetic levitation bearing part, the high-speed motor part and the fluid part, as shown in the figure below . The main function of the magnetic bearing part is to realize the suspension of the rotating shaft. It detects the displacement signal of the rotating shaft through the built-in radial sensor and axial sensor, sends the obtained signal to the magnetic bearing controller for conditioning, calculation and amplification to obtain the control current, and then inputs the control current into the radial magnetic bearing and axial magnetic bearing. The bearing generates a magnetic field through current, and the magnetic field generates suction, thereby achieving the suspension of the rotating shaft. The main function of the high-speed motor part is to drive the rotation of the rotor. It generates alternating current with controllable frequency through a variable frequency power supply, and inputs this alternating current into the stator of the motor to generate an alternating magnetic field, driving the rotor to rotate at high speed.
The main function of the fluid part is to realize air blast. The impeller that rotates at high speed with the rotor drives the air to enter from the air inlet of the volute. Under the guidance and pressurization of the volute, the air becomes a gas with a certain flow rate and pressure, and finally bulges out from the outlet of the volute. This The blowing of the fan is realized.
