What is the cavitation?
Cavitation
Group 4
Causes of cavitation
The suction head of pump is large
The velocity of impeller of pump is huge
The suction of pipe diameter of pump is small
Tank
Location of pump is higher than a source of water supply
The friction loss of pump is huge
Cavitation
Group 4
NPSH a : Pa - Hs - Hf - Pv
Pa = air pressure
Hs = the head of pump suction
Hf = the head of friction loss
Pv = pressure of saturated vapor
