Air Foil Bearing
Air foil bearing has features of long operating life, high reliability, good stability, strong load capability and high temperature resistance etc.
With the use of air film supporting shaft, It requires no lubrication, almost has no power loss and greatly reduces energy consumption.
The Coulomb friction inside air bearing restrains rotor vibration and make rotor vibration amplitude less than 0.02mm.
The rotor has passed 20,000 times start and stop test, ensuring air bearing semi-permanent lifespan.
Impeller is made of AL7075 material and adopts coating technology, which enables stable operation under ultra high speed.
Machined by five-axis machining center, impeller polytropic efficiency is more than 92% and impeller passes through the spin test of 115% rotation speed.
High Speed PMSM
Independent developed high speed PMSM(permanent magnet synchronous motor) apply advanced air cooling technology and reach a high efficiency of 97%.
High Speed PMSM is frequency controlled and has wide modulation range, simple and compact structure and high power density, high efficiency and excellent reliability.
Automated Intelligent System
Variable Frequency Drive(VFD) adjusts the rotation speed of high speed PMSM in order to automatically achieve required discharge pressure and flow rate to meet customer needs and reach the most economic running status.
Integrated Programmable Logic Controller (PLC) allows user friendly control, monitor and diagnostic all process parameters and blower condition on touch screen panel.
Multiply communication protocols include Modbus, Ethernet, Profibus etc.
