Reason for air absorption at the high point of the water cooler circulating water outlet
Thread Content
As the title indicates, it is a water cooler located on the third-level platform of the facility at a height of about 13 meters. The circulating water flows through the tube side, with water entering from the lower side and exiting from the higher side; the liquefied material flows through the shell side. The pressure gauge on the inlet side of the water cooler’s circulating water shows a pressure of around 0.2 MPa. Currently, unusual noises are being heard from the tube side; therefore, exhaust was allowed to flow from the high point of the circulating water return line. However, what was detected was suction instead. What could be the cause of this? Thank you!
Siphon effect – the pressure on the back side is lower. The cooler is installed at a high position, creating negative pressure at that high point.
Does it mean that the water flows back quickly due to insufficient inflow? Is that what it means?
A partial pressure is formed, resulting in a siphon effect-----------------------------
