This standard JB/T 53297-1999 specifies the quality grading requirements for vortex pump products, applicable to single-stage, two-stage, multi-stage self-priming, and centrifugal vortex pumps. It classifies products into three grades: qualified, first-class, and superior, and details technical indicators and test methods for key assessment items such as flow rate, head, efficiency, vibration, and noise. The standard also defines sampling and evaluation methods to ensure scientific and consistent quality assessment. It replaces JB/T 53297-94, with main changes including the deletion of the 'average efficiency reduction per thousand hours' assessment item and the relocation of some assessment items in the tables.
本标准JB/T 53297-1999规定了旋涡泵产品的质量分等要求，适用于单级、两级、多级自吸及离心旋涡泵。标准将产品分为合格品、一等品和优等品三个等级，并详细列出了流量、扬程、效率、振动、噪声等关键考核项目的技术指标和试验方法。同时，标准还规定了抽样和评定方法，以确保质量评定的科学性和一致性。该标准替代了JB/T 53297-94，主要变化包括删除千小时效率平均降低值考核项目，并调整了部分考核项目的表格位置。
Key Sentences extracted from text
本标准规定了旋涡泵产品的质量等级、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JB/T 7743 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4 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 vortex pump products.
Products are divided into three grades: qualified product, first-class product, and superior product, based on quality level and use value.
Products shall comply with the provisions of JB/T 7743, where the main assessment items and requirements shall comply with the provisions of Table 1, and the assessment items, indicators, and requirements for evaluating product quality grades shall comply with the provisions of Table 4.
For batch products, the quality grade of individual products shall first be evaluated; the quality grade of an individual product shall meet all assessment 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 superior) according to the acceptance number Ac (or A1, A2) and rejection number Re (or R1, R2) specified in JB/T 8687.
