As you can see, this is the layout diagram of our spherical tank. There are flow control orifice plates on the return line, and this return line meets the feed pump line at the collection pipe of the propylene tank. Our pumps have a capacity of 30 m^3/h, while the plant’s demand is only 3–4 t/h; therefore, we keep the return line in use. From May 12th to May 14th, our propylene pumps experienced cavitation on two occasions. I would like to ask everyone to help analyze the reasons for this and suggest solutions. Our pumps are vertical barrel-type pumps.
