This standard JB/T 53306-1999 specifies the product quality grading requirements for pipeline centrifugal oil pumps, applicable to refineries, chemical and petrochemical processes. It classifies products into three grades: qualified, first-class, and premium. Key inspection items include flow rate, head, NPSH, efficiency, vibration, noise, and shaft seal leakage, with corresponding test methods. The standard also defines sampling and evaluation procedures, requiring individual product assessment first, then batch grading based on 100% inspection or sampling results.
本标准JB/T 53306-1999规定了管道式离心油泵的产品质量分等要求，适用于炼厂、化工及石油化工流程。标准将产品分为合格品、一等品和优等品三个等级，考核项目包括流量、扬程、汽蚀余量、效率、振动、噪声、轴封泄漏量等，并规定了相应的试验与检验方法。标准还明确了抽样和评定方法，要求批量产品先进行单台评定，再根据全数检查或抽样检查结果确定批次等级。
Key Sentences extracted from text
本标准规定了管道式离心油泵产品的质量等级、试验与检验方法和抽样、评定方法。
产品根据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。
产品应符合GB/T 3215、JB/T 6537 的规定，其中主要考核项目及要求应符合表1 的规定，评定产品质量等级的考核项目、指标和要求应符合表2 的规定。
批量产品应首先进行单个产品的质量等级评定，判定单个产品的质量等级应符合该等级全部考核项目的要求，否则按达到的最低一项指标定等。
采取抽样检查方法时，可按JB/T 8687 规定的合格判定数Ac（或A1、A2）和不合格判定数Re（或R1、R2）评定该批产品达到某一等级（合格品、一等品或优等品）。
This standard specifies the quality grades, test and inspection methods, and sampling and evaluation methods for pipeline centrifugal oil pump products.
Products are divided into three grades: qualified product, first-class product, and premium product, based on quality level and use value.
Products shall comply with the provisions of GB/T 3215 and JB/T 6537, wherein the main inspection items and requirements shall comply with Table 1, and the inspection items, indicators and requirements for evaluating product quality grades shall comply with Table 2.
For batch products, the quality grade of individual products shall first be evaluated; the quality grade of an individual product shall meet all inspection items of that grade, otherwise it shall be graded according to the lowest indicator achieved.
When using the sampling inspection method, the batch product can be evaluated as reaching a certain grade (qualified, first-class, or premium) according to the acceptance number Ac (or A1, A2) and rejection number Re (or R1, R2) specified in JB/T 8687.
