What should be the minimum pressure in the coating tank liquid pipeline during tank coating?
Thread Content
I have a question: what should be the minimum pressure in the coating liquid pipeline during normal coating processes?
The outlet pressure of the coating tank liquid pump in our factory is 0.8 MPa; regardless of the pressure, it must be higher than the pressure inside the tank.
It’s not correct to say that as mentioned upstairs; generally, it needs to be more than 3 kilograms higher than the pressure in the boiler, otherwise a jet-like flow won’t be formed
Reply to 3# TZPCE0019: Yeah, that’s right. Because the coating liquid needs to be applied to the tank wall via a sprayer (to reduce velocity and increase pressure).
A pressure of 3 kilograms higher than that of the reactor is sufficient; if the pressure inside the reactor is close to 0, 3 kilograms of compressed gas can be used to push it in, and the result will also be good
It is usually 3 kilograms; using medium-pressure steam improves the atomization effect!
