Here's a rewritten version of the text regarding the hazards of water in hydraulic oil:
The presence of water in hydraulic oil is more common than one might think, and according to industry professionals, it is impossible to avoid entirely. It is important to note that a gradual increase in water content, coupled with a lack of maintenance, can lead to serious problems, such as:
Downtime of machinery Decreased performance speed Reduced productivity Operational difficulties Increased maintenance costs Need for replacement parts Accelerated equipment wear Experts explain that water can exist in hydraulic oil in three ways: dissolved, free, and emulsified.
Dissolved water: In this phase, water is uniformly dissolved in the oil, which appears shiny and clean. Free water: This occurs when water separates from the oil, typically settling at the bottom of a reservoir. Emulsified water: This happens when the hydraulic oil becomes saturated and is unable to absorb more dissolved water. The oil starts to become cloudy and dark, representing the most dangerous stage for the hydraulic system.
