This standard JB/T 53282-1999 specifies the quality grading requirements for general purpose Roots blower products, classifying them into three grades: qualified, first-class, and premium. It details specific indicators for each grade regarding volume flow deviation, volume specific energy deviation, vibration velocity RMS value, rotor dynamic balance quality grade, gear precision, and pass rate of main items. The standard also prescribes test and inspection methods, sampling plans, and grade determination rules for both single units and batches, providing a unified basis for quality assessment of blower products.
本标准JB/T 53282-1999规定了一般用途罗茨鼓风机产品的质量分等要求，将产品分为合格品、一等品和优等品三个等级。标准详细列出了各等级在容积流量偏差、容积比能偏差、振动速度均方根值、转子动平衡品质等级、齿轮精度和主要项目合格率等方面的具体指标。同时，标准还规定了试验与检验方法、抽样方案以及单台和批量产品的等级判定规则，为鼓风机产品的质量评估提供了统一依据。
Key Sentences extracted from text
本标准规定了一般用途罗茨鼓风机的产品质量等级，试验方法和抽样及判定方法。
鼓风机产品根据其质量水平分为合格品、一等品和优等品三个等级。
鼓风机主要零部件的关键项目合格率应达到100%，其项目为：主动轴、从动轴与滚动轴承的配合尺寸；转子动平衡品质等级。
根据抽样检查的结果，若抽样中不合格品数小于或等于合格判定数Ac，则判断该批产品是合格的，若抽样中不合格品数大于或等于不合格判定数Re，则判断该批产品是不合格的。
单台产品的等级判定，按本标准进行，各项质量指标都必须达到本标准的规定，并且以其中最低的一项指标判定产品的等级。
This standard specifies the product quality grades, test methods, and sampling and determination methods for general purpose Roots blowers.
Blower products are divided into three grades according to their quality level: qualified product, first-class product, and premium product.
The pass rate of key items for main parts of the blower shall reach 100%, and the items are: the fit dimensions of the driving shaft and driven shaft with rolling bearings; the rotor dynamic balance quality grade.
Based on the results of sampling inspection, if the number of nonconforming units in the sample is less than or equal to the acceptance number Ac, the batch is judged as acceptable; if the number of nonconforming units in the sample is greater than or equal to the rejection number Re, the batch is judged as unacceptable.
The grade determination of a single product shall be carried out according to this standard, all quality indicators must meet the requirements of this standard, and the grade of the product shall be determined by the lowest indicator among them.
Standard Timeline
Changes from replaced version:
- 对流量偏差、振动速度均方根值的分等指标进行了适当的修改，以容积比能偏差代替JB/T 53282—94中的比功率限值考核
- 去掉了JB/T 53282—94中对轴承部位温度的考核
- Appropriate modifications were made to the grading indicators for flow deviation and vibration velocity RMS value, replacing the specific power limit assessment in JB/T 53282—94 with volume specific energy deviation
- Removed the assessment of bearing temperature in JB/T 53282—94
