新世纪第一个节能宣传周到来之际 ,对机械工业开展的节能工作进行一下回顾 ,很有必要。机械工业是我国能源消耗的最大用户 ,风机、水泵、电动机、工业炉窑、中小型内燃机等2 1类产品的耗电量占全国发电量的 70 % ,耗煤炭量占全国总产量的 40 % ,柴油耗量占全国产量的 45 %。目 When the first energy-saving publicity week of the new century arrives, it is necessary to review the energy-saving work carried out by the machinery industry. The machinery industry is the largest user of energy consumption in China. The power consumption of wind turbines, water pumps, electric motors, industrial furnaces, and small and medium-sized internal combustion engines accounts for 70% of the country’s total electricity generation, and coal consumption accounts for 40% of the country’s total output. The consumption of diesel accounts for 45% of the national output. Head
