Water In Hydraulic Oil Excavator

Wickberg marine contracting is no stranger to operating excavators around water.

Water in hydraulic oil excavator. I recently audited a hydraulic system with cloudy oil that was found to contain greater than 1 10 000 ppm water. Hydraulic fluid at left clearly separates out or de emulsifies the water that accumulates in the system. It gives a clearer warning of impending formation of free water. Note that if hydraulic oil is cloudy it indicates that a minimum of 200 300 ppm of water is present.

There are a variety of techniques to measure the quantity of water in hydraulic fluids and lubricants. Relative content expressed as percent of saturation indicates the fluid water content relative to its saturation level at a given temperature. The saturation level is the amount of water that can dissolve in the oil s molecular chemistry and is typically 200 300 ppm at 68 f 20 c for mineral hydraulic oil. Reduces filterability and clogs filters.

I recently audited a hydraulic system with cloudy oil that was found to contain greater than 1 10 000 ppm water. Depletes some additives and reacts with others to form corrosive by products which attack some metals. Note that if hydraulic oil is cloudy it indicates that a minimum of 200 300 ppm of water is present. If water is making its way into your hydraulic oil you should address both the cause and the solution as quickly as possible.

Water in hydraulic oil. Water especially free water not dissolved in the oil can cause corrosion modify viscosity reduce lubrication and increase oxidation. The saturation level is the amount of water that can dissolve in the oil s molecular chemistry and is typically 200 300 ppm at 68 f 20 c for mineral hydraulic oil. This belford nj based dredging contractor has four hydraulic dredges and mechanically dredges with long reach.

Increases air entrainment. Reduces lubricating film strength which leaves critical surfaces vulnerable to wear and corrosion. I recently audited a hydraulic system with cloudy oil that was found to contain greater than 1 10 000 ppm water.
