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.
