两级压缩空压机何以比单级压缩节能?
How could two stage compression compressors be more energy saving than single stage compressing ones?
根据压缩机的工作原理知道,等温压缩是相对省功的。右图为压缩过程的示功图,曲线12'3'为等温压缩过程,与纵坐标成的面积613'4为等温压缩的指示功。曲线123"为一级压缩过程,与纵坐标形成的面积613"4为一级压缩的指示功。曲12、22'、2'3为两级压缩过程,与纵坐标形成的面积6125和52'34之和(6122'34)为两级压缩的指示功。由图示可以看出,等温压缩613'4面积(指示功)*小,但在压缩机实际压缩过程中无法做到等温压缩,一级压缩比等温压缩多出了13'3"面积的功率,而两级压则比一级压缩节省了2'23"3面积的功率。
According to the working principle of the compressor, isothermal compression is relatively energy-saving. The right figure is the indicator diagram of the compression process, the curve l2'3 'is the isothermal compression process, and the area 613 '4 formed with the ordinate is the indicator work ofthe isothermal compression. The curve 123 " is the primary compression process, and the area 6l3 " 4 formed with the ordinate is the indicator work of the primary compression.Curves 12,22 'and 2'3 are two-stage compression processes, and the sum of the areas 6l25 and 52 '34 formed by the ordinate (6122'34)is the indicative work of two-stage compression.lt can be seen from the figure that the 6l3'4 area (indicating work)in the isothermal compression process is the smallest, but the isothermal compression cannot be achieved in the actual compression process of the compressor. The first stage compression has 13 '3 " more power than the isothermal compression, while the two stage compression saves2'23 "3 area power than the first stage compression.

两级压缩过程
Two stage compression process
自然空气通过空气过滤器进入第 一级压缩,在压缩腔与少量润滑油混合,同时将混合气体压缩到级间压力。压缩后的体进冷却通道,与大量油雾接触,从而大大降低了温度。降温后的压缩气体进入第二级转子,进行二次压缩,被压缩到终排气压力。*后通过排气阀门排出压缩机,完成整个压缩过程，
The natural air enters the first stage for compression through the air filter,mixes with a small amount of lubricating oil in the compression chamber,and compresses the mixed gas to the interstage pressure. The compressed pas enters the cooling channel and contacts with a large amount of oil mist, thus greatly reducing the temperature.The cooled compressed pas enters the second stage rotor for secondary compression and is compressed to the final exhaust pressure. Finally, the compressor is discharged through the exhaust valve to complete the whole compression process.
