Screw Compressor Two-Stage Variable Speed Direct Drive PM VSD
Research Background:
Compressed air is the second largest power source m the world after electric power it is urgent to save energy and reduce emissions. The use of two-stage permanent magnet frequency converter air compressor not only benefits the country and the people, but also provides a sustained, powerful and reliable gas source for enterprises to enhance their competitiveness.
Two-stage permanent magnet variable frequency screw air compressor developed by our company has not only large gas volume, low energy consumption and stable quality, but also all rotor parts are processed and manufactured in China, solving the problem of after-sale maintenance, low maintenance cost, breaking international monopoly, not being stuck by famous foreign brands. and having a design life of more than 25 years.
The unit efficiency is the basis of permanent magnet variable frequency air compressor. The energy efficiency will be increased by another 15%, and the total efficiency will reach the national level 1 energy efficiency standard
