Abstract

This study addresses the need for a systematic approach to evaluating the performance of vacuum pumps through the design of a dedicated experimental test system. The proposed system is developed to determine and measure key operating parameters of a vacuum pump under controlled conditions. Particular emphasis is placed on the relationship between vacuum pressure and the time required to achieve it, which serves as a critical indicator of pump efficiency. The design and implementation of this experimental setup constitute a
fundamental step toward subsequent investigations aimed at optimizing vacuum pump performance.
