Abstract

Pumps are designed and manufactured to operate far from the cavitation condition. Pump designers define the cavitation inception point as the point where the head drops by 3 %. This definition is incorrect, because the first appearance of vapour bubbles is observed earlier than 3 % drop in the head. Therefore, using 3 % drop in head, as indication parameter for cavitation inception has always resulted in damage in pumps during operation. This paper describes visual studies conducted to determine the variation of net positive suction head with flow rate, rotational speed and water temperature. The experiments showed that the visual incipient of cavitation in the pump was existed long before drop in pump head occurs. A special correlation between the visual inception cavitation net positive suction head and net positive suction head corresponding to 3 % drop in head was developed at various operating conditions.
