The main function of the fan is to achieve air blowing. The impeller, rotating at high speed along with the rotor shaft, drives the air and performs work on it.
Magnetic levitation blowers use magnetic levitation bearings, which eliminate contact loss and mechanical loss, enabling high-speed stepless variable speed regulation. The operational efficiency of the fan can reach up to 84.5%, saving over 25% more electricity compared to traditional Roots blowers. Additionally, the machine employs a high-speed permanent magnet motor for direct drive, with the ternary flow impeller directly installed on the main shaft of the high-speed motor. The entire system integrates permanent magnet synchronous DC motors, electrically driven magnetic levitation bearings, high-speed frequency conversion, electromagnetic filtering, closed-loop cooling circulation, and automatic control technologies into one unit. The equipment operates without any friction during operation. It runs smoothly, with overall efficiency meeting design requirements, achieving over 8% higher efficiency compared to gear-driven single-stage high-speed blowers. The downside is its high price, but the electricity savings after two years of use make it more economical than other fan equipment. Simply put, it is expensive to buy but cheap to use. Magnetic levitation centrifugal blowers are accepted by high-end customers due to their frictionless, lubrication-free, maintenance-free, low-noise, and high-efficiency characteristics. Although the overall price is higher, the significant electricity savings provide clear benefits to customers. Energy-saving, maintenance-free.
Main Technical Features of Magnetic Levitation Blowers
(1) Energy-saving: Utilizes magnetic levitation bearings, eliminating contact loss and mechanical loss, enabling high-speed stepless variable speed regulation, with fan operational efficiency reaching up to 84.5%.
(2) Low noise, easy installation: Due to the integrated box-type structure, the fan noise is below 80dB, with minimal body vibration, eliminating the need for an installation foundation.
(3) High system integration: Includes imported filters, cooling systems, fully automatic anti-surge systems, power outage and fault protection systems, etc., eliminating the need for users to purchase additional components. The real-time display Chinese touchscreen provides convenience for operators and reduces operational accidents.
(4) High cooling efficiency: The cooling system combines air and water cooling, effectively protecting the motor and allowing the fan to start and stop at any time.
(5) Remote control: Utilizes PLC + GPRS. It can be controlled from the central control room, and if the fan malfunctions, remote maintenance and debugging can be performed.
Magnetic levitation centrifugal blowers are accepted by high-end customers due to their frictionless, lubrication-free, maintenance-free, low-noise, and high-efficiency characteristics. Although the overall price is higher, the significant electricity savings provide clear benefits to customers.
