HMGB MAGNETIC LEVITATION CENTRIFUGAL TURBO BLOWER
30~120KPA
1. Product introduction
The magnetic levitation high-speed centrifugal blower is a new type of high-efficiency, energy-saving and environmentally friendly blower formed by integrating the magnetic levitation bearing technology and high-speed motor technology into the traditional blower, with the significant advantages of simple structure, high-efficiency and intelligence, integration, simple operation and maintenance, and low operating costs.
2.Working principle
The magnetic levitation centrifugal blower uses the direct driving structure of high rotary speed permanent magnet motor, designed together with centrifugal impeller and motor driving. It monitors the vibration of shaft and space gap by the motion detector inside. Then it would transfer the signal to the magnetic levitation bearing controller to adjust, parsing, calculation, and producing controlling current, to transport the current into the magnetic bearing winding coil, and producing electro-magnetic force, then realize the levitation of shaft.
The main function of permanent magnet synchronous motor is to driving the rotary of shaft. It produces the frequency controllable current, and transport the current into the rotary magnetic field of motor stator, to drive the shaft rotary in a higher speed.
The blower's main function is to boosting air. The impeller, which whirling together with shaft, works on air. Air enters from the inlet collector of the volute, and the air becomes a gas with a certain flow rate and pressure under the guidance and pressurization of the volute, and finally blows out from the air outlet of the volute, to realize a gas delivery process with certain pressure and flow rate.

(1)High-power and high-speed permanent magnet synchronous motor
Adopt high-speed and high-power permanent magnet synchronous motor
The motor is small in size, light in weight and has high power density
The motor speed is high up to 60,000r/min
Stepless speed control can be achieved
The motor rotor and impeller are coupled to reduce intermediate energy consumption, low operating failures and high transmission efficiency
(2)High-efficiency centrifugal impeller
Using three-dimensional flow theory design and parameter optimization to maximize the impeller efficiency and wide working range
The centrifugal impeller is made of high-strength forged aluminum alloy or titanium alloy with strong deformation resistance
Precisely processed by a five-axis CNC machining center, it has good corrosion resistance
Each model of impeller we design has undergone long-term bench testing to ensure that its aerodynamic performance is efficient and reliable. The impeller variable efficiency can reach 85%, and it has passed the 115% overspeed test. Adopting variable frequency regulation, the guide vane adjustment is cancelled, the starting current is smaller, and the blower has a wider adjustable range
(3)Magnetic suspension bearing
No wear/no lubrication required, high-speed operation can be achieved
The rotor status can be monitored, and the bearing status can be monitored
No lubrication is required, reducing the size and weight of the shell
Semi-permanent life, maintenance-free
(4)High-power variable frequency speed regulation system
The measured frequency (output power/input power) of the inverter is as high as 98%.
The motor speed is adjusted by changing the output current frequency of the inverter, thereby adjusting the flow rate
It can be widely used in sewage treatment, petrochemical, pharmaceutical, textile, glass, electric power, mineral, food, paper and other industries, with remarkable energy-saving effect.
