This standard JB/T 53065-1999, replacing JB/T 53065-93, specifies the product quality grading requirements for booster turbo expanders. It classifies products into three grades: qualified, first-class, and premium, each with distinct performance targets for isentropic efficiency, operation cycle, vibration, and noise. The standard also defines test methods, sampling rules, and evaluation procedures, requiring that products meet the lowest indicator of all assessed items for grade determination. Applicable to booster expanders manufactured under JB/T 6894-1993, it aims to enhance product quality and international competitiveness.
本标准JB/T 53065-1999替代了旧版JB/T 53065-93，规定了增压透平膨胀机的产品质量分等要求。标准将产品分为合格品、一等品和优等品三个等级，每个等级对应不同的等熵效率、运转周期、振动和噪声等性能指标。标准还明确了试验方法、抽样规则和评定方法，要求产品必须满足所有考核项目的最低指标才能定级。该标准适用于按JB/T 6894-1993技术条件制造的增压膨胀机，旨在提升产品质量和国际竞争力。
Key Sentences extracted from text
本标准规定了增压透平膨胀机的产品质量等级、试验方法、抽样和评定方法。
增压膨胀机产品根据其质量水平和使用价值，分为合格品、一等品和优等品三个等级。
一等品应达到图1、图2、图3 和表1 中一等品的规定，并达到国际同类产品的较好水平。
优等品应达到图1、图2、图3和表1 中优等品的规定，并达到国际同类产品的当代先进水平。
判定产品质量等级必须符合该等级全部考核项目的质量指标，按达到最低一项指标定等级，缺项不能判定产品质量等级。
This standard specifies the product quality grades, test methods, sampling and evaluation methods for booster turbo expanders.
Booster expander products are divided into three grades: qualified product, first-class product, and premium product, based on their quality level and use value.
First-class products shall meet the requirements for first-class products in Figures 1, 2, 3 and Table 1, and reach a relatively good level of similar international products.
Premium products shall meet the requirements for premium products in Figures 1, 2, 3 and Table 1, and reach the contemporary advanced level of similar international products.
The determination of product quality grade must comply with the quality indicators of all assessment items for that grade, and the grade is determined by the lowest indicator achieved; missing items cannot be used to determine the product quality grade.
