This standard JB/T 53606-1999 specifies quality grades, test methods, and inspection rules for sand and gravel washing machines, applicable to spiral-type machines. Products are classified as qualified or first-class based on finished product inspection, production quality, and user feedback. Key requirements include overall performance (e.g., capacity, water consumption, noise), component performance (e.g., reducer sealing, gear precision), and reliability (e.g., first overhaul period ≥15,000 hours). Test methods cover noise, dimensional accuracy, and hardness. Inspection uses sampling, with the lowest grade determining the batch quality.
本标准JB/T 53606-1999规定了砂石洗选机的质量等级、试验方法和检验规则，适用于螺旋型砂石洗选机的质量评定。标准将产品分为合格品和一等品两个等级，依据成品检验、生产过程质量检查、用户评价等综合指标判定。关键要求包括整机性能（如生产能力、耗水量、噪声）、部件性能（如减速器密封性、齿轮精度）、可靠性与寿命（如第一次大修期≥15000小时）等。试验方法涵盖噪声、尺寸精度、硬度等检测，检验规则采用抽样方式，以最低等级评定整批产品。
