Aeration vs cavitation
WebNov 9, 2024 · Aeration devices (2) are designed to introduce artificially air within the flow upstream of the first location where cavitation damage might occur ( Figures 3 and 4) . Aerators are designed to deflect high velocity flow away from the chute surface ( Figure 4 ). WebOct 5, 2024 · Let’s look at the most common reasons for flow-related pump vibration. CAVITATION – True cavitation occurs when “cavities”, low pressure vapor bubbles, form in the liquid on the suction side of the pump. This can be from: Clogged suction strainers, or plugging on the suction side. Poor piping design.

WebDec 11, 2024 · “Aeration and cavitation are also related to high-speed operation as well. These will occur in any pump as the speed increases to the point where the oil can no longer fill the internal pumping chambers. As noted earlier, if the inlet pressure drops below the vapor point, then cavitation will occur as oil vapor bubbles will form in the oil.”
