What are the reasons for the sudden decrease in the flow rate of the acid pump to the tower?

Dear experts: What are the reasons for the sudden decrease in the flow rate of the acid pump to the tower? It dropped from 700 M3/H to 100 M3/H, then after reducing the frequency conversion backflow it returned to over 600. What’s the reason? Thank you!!! :(
The acid filter screen is clogged, or broken porcelain rings from a clogged filter have entered the impeller
The acid pump vibrates; when the flow rate is low, it loses the ability to restore the flow rate
It’s also possible that the level of the circulating liquid is too low.
The day before yesterday, I tested a new project for one of our clients, and vibration in the acid pump occurred there as well (it appeared after 18 hours of operation). I would like to know what could be the cause
There are two possible scenarios: 1. Something has gotten into the impeller of the acid pump, causing vibration and a low flow rate; when the pump is stopped, the object stuck in the impeller falls out and the pump operates normally, but once it starts running again, that object gets sucked back into the impeller. 2. There is air leakage due to a short circuit at the inlet of the dry suction pump – remove this short circuit, reinstall it, and then perform a pressure test again. We have encountered both of these scenarios; these are the only suggestions we can offer
Liquid level 63%, thank you! ! ! The liquid level is accurate
:victory: Thank you!
Are two acid pumps installed on one circulation tank?
