Pressure at the inlet of the residue pump at the bottom of the vacuum tower
Thread Content
Is the inlet of the vacuum tower bottom residue pump under positive pressure or negative pressure?
And negative pressure together with operating temperature ensure a good sealing effect in high-temperature environments. . Another option is to maintain a positive pressure inside the chamber. It is to select a pump with good elasticity at high temperatures, ensuring long-term efficient operation of the residue pump at the bottom of the vacuum tower as well as the overall performance of the facility.
It should be negative pressure; our device operates at negative pressure.
It’s very dangerous to evacuate a pump with a reduced bottom pressure! !
If the bottom of the vacuum tower is at positive pressure, air cannot easily enter, but the skirt of the tower must be relatively high.
It should be negative pressure; our device operates at negative pressure
Negative pressure: the seal oil of the standby pump will show a slight negative pressure
The chance of the pump being emptied is very low, especially since the reflux is turned on
