Adjustment of pressure difference in the balance line of the compressor’s dry gas seal
Thread Content
I have a question for the forum members: In my company, the set pressure difference for the primary seal gas balance pipe is usually 0.5 Mpa, but during this operation the pressure difference in the balance pipe has remained at 1.0 Mpa. I’m not sure how to adjust it so that it returns to the original setting
A normal pressure difference of 0.5 MPaG is quite high. Reset the control valve.
Was there already a problem with your original device?
Is the pressure in the gas seal too high, causing it not to drop even with the control valve fully closed?
That means the dry gas seal pressure is too high; lower the inlet pressure to ensure a pressure difference of four to five kilograms
It’s just a matter of adjusting the inlet valve of the dry gas seal, right?
But even though the control panel has turned off the control valve, it still doesn’t drop
