摘　　要：陕西西北有色铅锌集团有限公司凤县分公司采区井下空气压缩机均为螺杆式空气压缩机,设备采用星三角(Y-Δ)降压启动方式。运行中频繁的加载卸载不仅设备噪声大,对电网与管网冲击大,同时还极大的浪费电能。我们将之改造为变频启动,PID恒压运行加设备休眠功能,供气流量随生产需求变化,从而达到节能降噪、减小冲击的目的。The underground air compressor in the mining area of the Fengxian Branch of Shaanxi Northwest Nonferrous Lead-Zinc Group Co.,Ltd.is a screw air compressor,and the equipment is in star-delta(Y-Δ)Depressurization startup mode.Frequent loading and unloading in operation not only cause loud equipment noise and a great impact on the power grid and pipe network but also greatly wastes electric energy.It is transformed into frequency conversion startup,PID constant pressure operation and equipment sleep function,and the gas supply flow changes with the production demand,to achieve the purpose of energy saving and noise reduction and impact reduction.
