Effects of wear-ring clearance on cavitation performance of centrifugal pump

CAO Yu-liang;MING Ting-feng;HE Guo;SU Yong-sheng;College of Power Engineering,Naval Univ. of Engineering;Dept. of Management Science,Naval Univ. of Engineering;  
By using Zwart cavitation model and RNG turbulent model with turbulence viscosity modified,cavitation performance of a centrifugal pump with or without wear-ring clearance is numerically simulated.The simulation result demonstrates that "head-NPSHa" curves of the centrifugal pump with or without wear-ring clearance all have similar trends with the experimental ones,while the curves with wear-ring clearance more conform with the experimental results.Secondly,cavitation performance of the centrifugal pump with different gaps of front wear-ring clearance(0.2mm,0.5mm,0.9mm,1.3mm and 1.6mm)is numerically calculated respectively.Calculation results show that the increase of the gaps leads to the decrease of cavitation area on impeller when NPSHa is equal to or greater than 2.15 m,which is beneficial to cavitation performance of the centrifugal pump,and the increase of the gaps leads to the increase of cavitation area on impeller when NPSHa is equal to or less than 2.05 m,which is harmful to the cavitation performance of the centrifugal pump.
