目前在许多企业中使用着大量的空压机,而这些设备往往都是企业的耗电大户。根据我们走访的大量用户其使用的空压机实际运行效率普遍较低,多数在50%～70%左右。主要原因,一是设计院或用户在气量选型时由于对各设备的耗气量无法拿到准确的数据往往将裕量放的比较大,一般放到计算总需求量的30%左右,这就使得空压机实际运行时 Currently in many businesses using a large number of air compressor, and these devices are often the power of large enterprises. According to the large number of users we visited, the actual operating efficiency of air compressors used by them is generally low, mostly around 50% to 70%. The main reason is that when the design institute or the user chooses the gas quantity, the accurate data can not be obtained because of the gas consumption of each equipment, and the allowance is relatively large, which is generally put into the calculation of about 30% of the total demand. Making the actual operation of air compressor
