Water pollution in hydraulic oil is more harmful than solid particles, and water intrusion is mainly through the tank vent.
The fluid level in the tank will change at any time when the hydraulic system is working. When drawdown, moist air will enter the tank, the percentage of water vapor in the air directly dissolves in the oil, the part of the water vapour met cool we di and condensed water drop into the oil tank wall, this type of moisture absorption air temperature device specially designed for the above situation, which can effectively prevent the water into the tank, favorable to improve the working performance and reliability of the hydraulic system.
