Energy Saving
At present, all the world are worried about lack of energy sources. With the rapid development of economy, lack of energy sources are restricting economy growth increasingly. So energy saving and emission reduction are seriously concerned.
There are several ways to save energy, such as waste utilization, renewable sources, prohibition of power consuming device. It is no doubt that adopting technology of variable frequency speed adjusting to control high voltage motor on fan, pump and compressor is a good way in energy saving. 80% power consumption of load is on motor and power is mainly in range of 300~3200kW in power plant, water plant, steel plant and oil mill. After demonstrating, it is easy to reconstruct with variable frequency drive and energy saving rate can be 20~40% ...
