一般情况下,压缩空气站耗能占一个工厂耗能的2/3,因此空压站节能具有重要意义,对空压站进行变频节能改造及自动化控制很有必要。空压站变频自动控制主要以节能为目的,使电动机工作在工频以下,这样,不但节能,而且能延长各部件的使用寿命,减轻维修量,节约修理费用。以上海 INGERSOLL—RAND 压缩 Under normal circumstances, the compressed air station energy consumption accounts for a factory energy consumption of 2/3, so air compressor station energy saving is of great significance to the air compressor station frequency conversion energy saving and automation control is necessary. Air compressor station frequency automatic control mainly for the purpose of energy saving, the motor work in the frequency below, so that not only energy saving, but also to extend the service life of various components, reduce maintenance and save repair costs.
