摘要：

This article presents detailed experimental results of the influencing factors of flow rate, set pressure, and inlet pipe length of a pressure relief valve. In order to analyze the influence of different flow rates on the instability characteristics of pressure relief valve, the multi-stage output of pump flow is realized. In terms of modeling, we investigated the theory concerning instability in the system: the 3% rule boundary. Data analyses on typical stable, cycling, and chatter instability conditions are conducted. The stable boundaries of the 3% rule and the quarter-wave model are drawn, which are consistent with the experimental results.
