空压机在玻璃行业属于重点耗能设备,一般耗电量占企业用电的60％左右。如何合理选用空压机,在目前能源短缺的情况下,有着重要的意义。北京玻璃四厂在扩大生产过程中,合理选用空压机,取得了良好节能效果。该厂供电变压器容量为800KVA,平均负荷为580KW。原有一台4L-20/8型空压机,专供一台四段行列制瓶机用气,另二台4L-20/8型空压机供其它用气设备。去年底,该厂决定扩大生产规模。扩大一盘玻璃熔炉,需增加一台四段行列制瓶机。按照常规方案,只要增加一台L_2-10/8型空压机,可以满足用气量的需求。另外还要增加一些辅助设备,计算结果需增加耗电180KW,这样原变压器容量就不够了,要更换变压器和新敷
Air compressors are key energy-consuming devices in the glass industry, and generally consume about 60% of the electricity consumed by enterprises. How to reasonably select the air compressor has important significance in the current energy shortage situation. Beijing Glass No. 4 Plant in the expansion of production process, the rational selection of air compressors, and achieved good energy-saving effect. The factory’s power transformer capacity is 800KVA and the average load is 580KW. The original one 4L-20/8 air compressor is designed for the gas of one four-stage bottle-making machine, and the other two 4L-20/8 air compressors are for other gas equipment. At the end of last year, the factory decided to expand its production scale. To expand a glass furnace, add a four-stage bottle-making machine. According to the conventional scheme, as long as an L-2-10/8 air compressor is added, the demand for gas consumption can be satisfied. In addition, some auxiliary equipment must be added. The calculation result needs to increase the power consumption by 180KW, so that the original transformer capacity is not enough. It is necessary to replace the transformer and new equipment.
