摘要

The effect of stage number on operational characteristics of three different diameter deep well irrigation pumps was researched. The pumps were tested at three different RPM. The characteristics of all stages (1-6) of the pumps were determined in the opt. RPM. The tests were performed according to ISO 2548 regulations in three repetitions.rnStatistical analysis was applied on the function of the stage number, power and pressure in fully closed valve (FCV) and flow and best efficiency in full opened valve (FOV).rnAccording to the results of the research, on condition that the shaft diameter and impeller dimension were stable, the effect of stage number variation on power, pressure and efficiency was significant, whereas on flow it was non-significant.
