标准摘要
[中文适用范围]： 本标准规定了机械增压真空泵最大容许压差、有效压缩比、零流量压缩比和溢流阀压差的测量方法和特殊要求。 它适用于中真空或粗真空应用的机械增压真空泵，包括气冷机械增压真空泵和多机械增压真空泵系统。 它涵盖了与通常的正排量真空泵不同的机械增压器的特殊特性。 最大容许压差Δpmax、有效压缩比Keff、零流量压缩比K0和溢流阀压差Δp1是机械增压真空泵性能的特殊特征。 [外文原描述]： This document specifies methods and special requirements for measuring the maximum tolerable pressure difference, effective compression ratio, compression ratio with zero throughput and overflow valve pressure difference of mechanical booster vacuum pumps. It applies to mechanical booster vacuum pumps employed for medium vacuum or rough vacuum applications including gas-cooled mechanical booster vacuum pump and multiple mechanical booster vacuum pump systems. It covers particular characteristics of mechanical boosters that are different from those of the usual positive displacement vacuum pumps. Maximum tolerable pressure difference Δ p max , effective compression ratio K eff , compression ratio with zero throughput K 0 and overflow valve pressure difference Δ p 1 are special characteristics of the performance of mechanical booster vacuum pumps.
