介绍了压缩机气体含油量的红外线吸收测定法的基本原理──采样方法为四氯化碳溶解法,分析方法为红外线吸收法。采用FF-1油分分析仪对气体中的油分进行测定,因油极易溶解于四氯化碳溶液中,而四氯化碳能很好地透过3．4μ波长的红外光,油分则在3．4μ波长处有强烈的吸收峰。把含油四氯化碳溶液注入仪器,即可得出油分浓度,再经公式R＝VcC/Vw换算成气体中的含油量(R
The basic principle of infrared absorption measurement of compressor gas oil content is introduced. The sampling method is carbon tetrachloride dissolution method, and the analysis method is infrared absorption method. Using the FF-1 oil analyzer to measure the oil content in the gas, the oil is easily dissolved in the carbon tetrachloride solution, while the carbon tetrachloride is able to transmit 3.4μ wavelength infrared light well. The oil content is in the range of 3.4μ wavelength at a strong absorption peak. Oil carbon tetrachloride solution into the instrument, you can get the oil concentration, and then by the formula R = VcC / Vw converted into gas oil content (R
