What happens during hydraulic fluid aeration?

During hydraulic fluid aeration, air bubbles are introduced into the fluid, which can have significant implications for hydraulic system performance. When air becomes entrained in hydraulic fluid, it disrupts the fluid's ability to transmit power effectively. The presence of air reduces the compressibility of the fluid, leading to erratic hydraulic system performance, potential cavitation, and reduced lubrication effectiveness.

This phenomenon can result in damage to components, increase wear, and result in erratic operation of hydraulic devices. Maintaining fluid integrity is critical to the efficient operation of hydraulic systems, making aeration a key concern for hydraulic maintenance and operation. Understanding this process helps professionals address potential issues before they impact system performance.
