Abstract | ||||
The objective of the present study is to present new experimental results of the effect of solids on the cavitation inception of centrifugal pump under varying suction conditions. The experiments were conducted using sand slurry with different solids size at different concentration and different pump speed. Measurements of power consumption, flow rate, total head developed by the pump were made in order to obtain the effect of solids on the cavitation characteristics of centrifugal pumps handling slurries. The results show that the cavitation inception has been accelerated with increasing solid concentration, and pump speed while the particle size has little effect on cavitation inception. | ||||
