本文对离心泵从静止到终速的快速加速过程中的瞬态特性进行了理论和实验研究。测量了各种启动方案的瞬时转速、流量和总压升。理论计算的瞬态特性的预测开发和相应的实验结果进行了比较。研究结果表明，叶轮叶片周围的脉动压力和环量形成的滞后是造成涡轮泵起动过程中动态特性和准稳态特性差异的主要原因。
A theoretical and experimental study has been made on the transient characteristics of a centrifugal pump during its rapid acceleration from standstill to final speed. Instantaneous rotatinal speed, flow-rate, and total pressure rise are measured for various start-up schemes. Theoretical calculations for the prediction of transient characteristics are developed and compared with the corresponding experimental results. As the results of this study, it becomes clear that the impulsive pressure and the lag in circulation formation around impeller vanes play predominant roles for the difference between dynamic and quasi-steady characteristics of turbopump during its starting period.
