公司于2004年订购一台LGFD-10/8螺杆式压缩机一台,经过近一年多的实际运行,通过调查用气量已不能满足生产要求,根据生产用气的分布做如下统计调查。1现状调查1.1压滤机压滤机用气量为滤室容积的3倍,即30 m2压滤机约为1.59 m3/min;60 m2压滤机约为3.09 m3/min;80m2压滤机约为4.23 m3/min因管路较长,分叉支路也较多,因此管路有较大的损耗,从压缩机用气出口到压滤机及除尘设备用气接口有较大损耗。另外电弧炉电极夹头也需使用压缩机空气。1.3供气压力不合理
The company ordered a LGFD-10/8 screw compressor in 2004. After nearly a year’s actual operation, the gas used for investigation can no longer meet the production requirements, and the following statistical investigation is conducted according to the distribution of the gas used for production. 1 Status quo survey 1.1 Filter press Filter press gas volume is 3 times the volume of the filter chamber, that is, 30 m2 filter press is about 1.59 m3 / min; 60 m2 filter press is about 3.09 m3 / min; 80m2 filter press about 4.23 m3 / min. Due to the longer pipelines and more branching branches, the pipeline has greater losses, resulting in greater losses from the compressor air outlet to the filter press and the dedusting equipment air interface. In addition, the electric arc furnace electrode chuck also need to use compressor air. 1.3 gas pressure unreasonable
