摘　　要：简述了无油工艺螺杆压缩机在高硫火炬气的回收中出现吸气量严重下降的故障现象，通过分析螺杆压缩机的结构原理、系统的设置情况以及硫结晶的化学成因，提出了导致高硫火炬气螺杆压缩机气量下降的主要原因，提出了解决故障的方法。This paper introduced a fault phenomenon that the suction volume flow dropped down rapidly for oil free screw compressor used in high-sulfur flare gas recycling projects. By analyzing compressor＇s structure, compressor system arrangement and sulfur chemical genetic, the main reason causing the fault is put forward, and the main resolution is generalized.
