故障现象一病人在治疗舱内听到有节奏的烦杂锤击声。故障分析及排除当病人在舱内治疗时,听到烦杂的敲击声,心里烦燥,影响治疗效果。此种声音在舱外也能听到。由于治疗时,空气压缩机是停开的,空气压缩储气罐是静止的,杂音可能来自制冷机和鼓风机,而制冷机的蒸发器是密封在风包里,产生冷气靠鼓风机吹入舱内,舱内空气由压缩空气和余氧回到风包,产生循环,使舱内空气新鲜、温度适宜。首先将制冷机停机、杂音未消,鼓风机停机,杂音逐渐消失,判定是鼓风机产生的敲击声。于是将风包与鼓风机和氧舱
Symptoms A patient hears a rhythmic irritating hammering sound in the treatment cabin. Failure analysis and exclusion When the patient is treated in the cabin, he hears annoying knocking sounds, irritable heart, affecting the treatment effect. This sound can also be heard outside the cabin. Since the air compressor is stopped during treatment, the compressed air tank is stationary. The noise may come from the refrigerator and the blower. The evaporator of the refrigerator is sealed in the air bag, and the cold air is generated by the blower. The air in the cabin is returned to the wind pack by the compressed air and the residual oxygen, and the circulation is generated, so that the air in the cabin is fresh and the temperature is suitable. First, the chiller is stopped, the noise is not eliminated, the blower stops, and the noise gradually disappears. The judgment is the knocking sound generated by the blower. So the wind bag with blower and oxygen cabin
