This standard JB/T 53061-1999 replaces JB/T 53061-93 and specifies quality grades (qualified, first-class, premium), test and inspection methods, and sampling evaluation methods for chemical centrifugal pumps. It applies to single-stage centrifugal pumps for corrosive liquids, with other pump types as reference. Key assessment items include flow rate, head, NPSH, efficiency, vibration, noise, and shaft seal leakage, with specific indicator requirements for each grade. Batch product quality is evaluated through full inspection or sampling inspection to ensure reliability and consistency.
本标准JB/T 53061-1999替代了JB/T 53061-93，规定了化工用离心泵的质量等级（合格品、一等品、优等品）、试验与检验方法以及抽样评定方法。适用于输送腐蚀性液体的单级离心泵，其他型式泵可参照执行。标准将流量、扬程、汽蚀余量、效率、振动、噪声、轴封泄漏量等作为主要考核项目，并明确了各等级的具体指标要求。通过全数检查或抽样检查评定批次产品质量，确保产品可靠性和一致性。
Key Sentences extracted from text
本标准规定了化工用离心泵产品的质量等级、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 5656、GB/T 5662 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 chemical centrifugal 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 5656 and GB/T 5662, with the main assessment items and requirements conforming to Table 1, and the assessment items, indicators, and requirements for evaluating product quality grades conforming to 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 assessment item requirements for 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.
