Vibration of the reflux liquid outlet at the top of the floating valve tower
Thread Content
I would like to ask the experts: The outlet of the reflux stream at the top of the floating valve tower is vibrating violently. How can this be resolved? Is a U-turn needed? The slight positive pressure at the top of the tower is 0.2 bar, the pressure at the pump outlet is 3 bar; the medium is water, with water vapor present at the top of the tower. Vibration is intense at the location shown in the figure:
First, it is necessary to determine whether this phenomenon is congenital or acquired. If it occurs the day after, we need to examine how it happened. Additionally, this is related to the adjustment of the pipe supports. It might be that some gaskets have fallen off due to long-term use, which is also a major cause of vibration; this is provided for reference.
For floating valve trays, the outlet of the reflux pipe after entering the tower is usually submerged in the liquid within the inlet weir area.
