Explain the effect of cavitation on propeller blades?
The BLADES ON THE IMPELLER GATHER BUBBLES AND POP. THE POP OF THE BUBBLES BREAK AND INDENT THE IMPELLER AND GUIDEVANE THAT HELPS THE WATER OR FLUID GO FROM THE MIDDLE OF THE IMPELLER TO THE LEADING EDGE OF THE IMPELLER. THE SOUND OF CAVITATION IS LIKE PUMPING GRAVEL THROUGH THE VOLUTE OR CASE. IF THE PUMP IS CAVITATING YOU CAN SLOWING CLOSE A BALL VALVE ON THE DISCHARGE SIDE OF THE PUMP ON A CENTRIFUGAL PUMP AND THE GRAVEL NOISE WILL GO AWAY AND YOU KNOW THE PUMP IS CAVITATING. CAVATION WILL DESTROY AN IMPELLER VERY FAST BY IMPLODING BUBBLES ON THE METAL OR PLASTIC UNTILL THE PUMP WILL NOT RUN.
