空气压缩机是一种广泛使用而耗能较高的设备。例如,排气量为20米~3/分的4L-20/8型空压机,轴功率就为118千瓦,配套电机的功率为130千瓦。排气量为40米~3/分的5L-40/8型空压机,轴功率为220千瓦,配套电机的功率达250千瓦。仅据煤炭工业部的八个矿务局的调查统计,空压机的耗电量就占整个矿山总耗电量的11.6%。在其它使用空压机的场合,其耗电量也是相当大的。因此,在能源紧缺的今天,设法节省空压机
Air compressors are a widely used and energy-intensive device. For example, a 4L-20/8 air compressor with a displacement of 20 m 3 / min has a shaft power of 118 kW and an accessory motor of 130 kW. Displacement of 40 m ~ 3 / min 5L-40/8 air compressor, shaft power of 220 kW, matching motor power up to 250 kilowatts. According to the survey conducted by the eight mining bureaus of the Ministry of Coal Industry, the power consumption of air compressors accounts for 11.6% of the total power consumption of the mine. In other occasions using air compressor, the power consumption is quite large. Therefore, in the energy shortage today, try to save air compressor
