标准范围

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 Δp_max , effective 
compression ratio K_eff , compression ratio with zero throughput K ₀ and overflow valve pressure 
difference Δp₁ are special characteristics of the performance of mechanical booster vacuum pumps.
