由于空压站产气量计量受仪表设计状态、工作状态、公称状态压力、温度的影响，须进行多次换算，使其单耗计算变得繁复。在总结历年机械工业企业空压站单耗考核经验的基础上，对采用差压式孔板流量计计量压缩空气量的空压站，推导出适合我省空压站单耗的简易计算方法。 As the gas station gas measurement by the instrument design status, working conditions, the nominal state pressure, temperature, to be carried out several conversion, making the unit consumption calculation becomes complicated. Based on the summing up experience of single unit air consumption assessment of mechanical industrial enterprises in the past years, a simple calculation method suitable for the unit air consumption of air compressor station in our province is derived for the air compressor station which uses the differential pressure orifice flowmeter to measure the amount of compressed air.
