Abstract:As an important period of self-priming process, the startup process of self-priming pump is inevitable. In this paper, a small overhung self-priming centrifugal pump is tested to reveal the effect of startup time on startup performance. As a first step, the startup performance of the pump delivering water is tried firstly. Through testing, the transient characteristics of performance variables against time are emphatically analyzed in three lengths of startup time/duration and four typical steady flow rates.
