一、系统装置节能重要性流体机械在工业部门中应用最广泛,而且耗能较高。在钢铁中,据1979年统计,全年用电占当年全国总发电量的9%左右,而钢铁厂中的流体机械耗电量约占全厂用电量的48.8%。在煤矿中通风、排水、动力空气是耗电的一个主要方面,据淮南、北票、本溪、抚顺等矿务局的统计,泵、风机和压缩机平均耗电量约占总用电量的64.6%。在石油化工和炼油工业 First, the importance of energy-saving system installation Fluid machinery in the industrial sector is the most widely used, and high energy consumption. In steel, according to the statistics of 1979, the annual electricity consumption accounted for about 9% of the total electricity generation in that year in the country, while the fluid mechanical power consumption in steel mills accounted for 48.8% of the total electricity consumption of the whole plant. According to the statistics of Huainan, Beipiao, Benxi, Fushun and other mining bureaus, the average power consumption of pumps, fans and compressors accounts for the total electricity consumption 64.6%. In the petrochemical and refining industries
