Dissolution problem in the air dissolution tank

Recently, we’ve noticed that the dissolution of air in the water is not optimal without changing the flow rate of the saltwater stream; the liquid level in the air-dissolving tank as well as the corresponding pressure often require adjustment by controlling the amount of gas used. This kind of situation didn’t occur before. Please help analyze what’s going on………… -

Reply to 2# Happy Forever123: The aeration is very poor, and the reason cannot be identified
Reply to 3# 393763501: What is the liquid level? What’s the pressure?
Reply to 4# Happy Forever123: We usually start compressing when the liquid level reaches 50%, at which point the pressure is generally 0.27 MPa. If compression is not applied, the liquid level will continue to rise
Aren’t your pressure pumps variable-frequency?
Reply to 6# 5566088: Yes
Reply to 5# 393763501: In our factory, we start opening the gas valve when the liquid level reaches 50%, and the pressure is usually between 0.18 and 0.22 MPa. The liquid level in the pressurized container is set at 60% – have you set the frequency conversion parameter?
