膨胀机的冰堵及预防处理措施

Blockage of the Expander and the Preventive Measures

以膨胀机在长周期运行的过程中出现的加工空气量过大或空气温度过高,造成空气中含水量增多,在膨胀机的导流器和喷嘴叶片上产生了"冰堵"现象,导致膨胀机的制冷量不足或换热效果不好这一问题,进行深刻的剖析和研究,并探讨相应的预防处理措施。

To expansion machine in long cycle run of process in the appeared of processing air volume had big or air temperature high,caused air in the moisture increased,in expansion machine of diversion device and nozzle leaves Shang produced has＂ice blocking＂phenomenon,led to expansion machine of refrigeration volume insufficient or for hot effect bad this a problem,for deep of analysis and research,and discussion corresponding of prevention processing measures.
