ABSTRACT

To prevent power overload, centrifugal pumps are usually started with the valve closed. In view of the little research on the transient characteristics of centrifugal pumps during closed-valve start-up, this paper presents a numerical simulation of the internal flow field of a low specific speed centrifugal pump during rapid closed-valve start-up with the non-constant flow by numerical simulation techniques. The study shows that the overall internal pressure tends to increase gradually with the increase of rotating speed.
