Image caption: This is a photo of the internal wall corrosion at the inlet reducer of a pump. What do you think are the causes? Share your opinions! ! !
Pneumatic hammer scouring. . . . Agoraphobia. . . . . Aaaaaah
It’s probably cavitation; one of our pumps had the same issue, and things were fixed after modifying the inlet pipeline
Isn’t cavitation caused by the breakdown of bubbles inside the pump, which then damages the impeller? What is the principle behind cavitation in the inlet pipeline? What changes were made to your inlet piping?
Is it because the diameter change there is too rapid, resulting in high flow rates and low pressure, which causes cavitation?
What materials are you using?
This is not like cavitation in pumps; cavitation starts at the end of the impeller, and tees do not experience cavitation. Moreover, the result of cavitation is the formation of small sponge-like pits, which are bulged
