AI Summary AI generated
This standard specifies product quality grades, test methods, and sampling/evaluation methods for centrifugal compressors. Products are classified into qualified, first-class, and premium grades based on quality level, with assessment items including shaft power deviation, balance quality grade, vibration accuracy, first major overhaul period, and pass rate of main items. Performance tests are conducted per JB/T 3165, with random sampling of one unit, and grade determination requires meeting all specified criteria.
本标准规定了离心压缩机的产品质量等级、试验方法和抽样评定方法。产品按质量水平分为合格品、一等品和优等品三个等级，考核项目包括轴功率偏差、平衡品质等级、振动精度、首次大修期和主要项目合格率等。试验方法要求按JB/T 3165进行性能测试，抽样随机抽取一台，判定等级需满足所有考核项目。
