centrysystem2s是美国COBE第二代产品，它采用先进的容量控制脱水法实现血液透析功能，这里结合一例该机平衡腔室部分的典型故障，分析探讨其基本的检修思路。故障现象：机器发出E33报警，并在五次之后升级为E13报警。分析：E33报警表明平衡腔室左侧阀短时泄漏，它可报警五次，
The centrysystem2s is the second generation of COBE in the United States. It uses advanced capacity-controlled dehydration to achieve hemodialysis. Here, an example of the typical failure of the balance chamber of the aircraft is analyzed and discussed. Symptom: The machine issues an E33 alarm and upgrades to an E13 alarm five times. Analysis: E33 alarm indicates that the left valve of the balance chamber leaks for a short time. It can alarm five times.
