This standard JB/T 53022-1999 specifies quality grades, inspection rules, and evaluation methods for slide valve vacuum pumps, applicable to products defined in JB/T 1246. It classifies products into qualified, first-class, and premium grades, with assessment items including ultimate pressure, ultimate total pressure, pumping speed efficiency, noise, specific power, and mean time between failures. A single sampling plan is used, with 2 units per batch and an acceptance number of 0. The batch grade is determined by the lowest grade among the samples.
本标准JB/T 53022-1999规定了滑阀真空泵的质量等级、检验规则和评定方法，适用于JB/T 1246规定的产品。标准将产品分为合格品、一等品和优等品，考核项目包括极限压力、极限全压力、抽气效率、噪声、比功率和平均无故障工作时间。采用一次抽样方案，每批抽2台，合格判定数为0。批的质量等级以样品中最低等级判定。
