罗茨真空泵性能考核指标——极限压力的探讨

Study on the Ultimate Pressure——Main Performance Index of Roots Vacuum Pump

本文论述了目前国内罗茨真空泵以极限压力作为主要性能指标所存在的考核难的问题，提出了罗茨真空泵标准中以漏率取代极限压力作为性能考核指标的合理性和可行性。

Abstract We use ultimate pressure as the main performance index of Roots vacuum pump at present. This paper proposes to use leakage as the main index instead of ultimate pressure. Test confirmed that is reasonable and practicable.
