1 分析与检修故障现象为空压机输出压力比正常值低。检查空压机进气、出气口均没有堵塞现象 ,空压机电流 3.5 A(正常 ) ,判断为空压机活塞环磨损 ,更换后空压机输出压力达到要求。空压机输出压力低 ,进入空氧混合器的空气量少 ,影响空氧浓度又无报警声 ,判断空氧混合器或氧浓
1 Analysis and troubleshooting The failure phenomenon is that the compressor output pressure is lower than the normal value. Check the air compressor inlet and outlet ports are not blocked, air compressor current 3.5 A (normal), judged to be the compressor piston ring wear, after the replacement of the air compressor output pressure to meet the requirements. The output pressure of the air compressor is low, the amount of air entering the air oxygen mixer is small, the concentration of air oxygen is affected and there is no alarm sound, judging the air oxygen mixer or oxygen concentration
