Magnetic Levitation Blower
The magnetic levitation blower uses a high-speed permanent magnet synchronous motor directly connected to the efficient three-element flow energy-saving impeller, combined with magnetic levitation bearing technology. The magnetic levitation blower uses a high-speed permanent magnet synchronous motor directly connected to a high-efficiency ternary flow energy-saving impeller, combined with magnetic levitation bearing technology. Due to the absence of traditional bearing friction loss, it can save 30%~50% compared with traditional fans, reduce noise from 130 decibels to below 85 decibels, and the whole machine is maintenance-free (except for dust screens), with a lifespan of more than 20 years, greatly reducing user operating costs. It is a product of industry transformation and is widely used in industries such as sewage treatment, papermaking, steel, thermal power, chemical, pharmaceutical, and food.

Overview of working principle 
The electrical control system of the magnetic levitation high-speed blower uses a PLC+touch screen control mode. By collecting and calculating the data from the frequency converter, magnetic levitation bearing controller, and temperature, pressure, and flow sensors, it achieves automatic control of the blower and real-time monitoring of its operating state. The touch screen displays real-time data and parameters such as motor speed, fan flow rate, motor coil temperature, outlet temperature, inlet temperature, inlet pressure, cabinet pressure difference, outlet pressure, fan power, and operating current. 

In addition to providing "local" control mode, the blower also has a "remote" control interface to meet the needs of the centralized control room's remote start/stop control of the blower and real-time monitoring of operating parameters and status. 

Application Fields 

Urban wastewater treatment: the main function of wastewater treatment is to aerate the water to increase the oxygen content in the water, thereby removing iron, manganese, or promoting the degradation of organic matter by aerobic microorganisms, in order to remove easily oxidizable precipitable substances. In addition, aeration allows for thorough contact between water and air to exchange gaseous substances and remove volatile substances from the water.
Gas and material conveying: gas conveying of mining, construction materials, industrial materials, food materials, such as mine ventilation, cement, lime, chemical powder, flour, etc.
Industrial manufacturing applications: paper mills, electroplating industry, brewing industry, textile industry, dairy processing, thermal power industry, electronic industry, etc.
