•
With hydraulic systems the main criterion for reliability and operating life is very thorough regularly
maintenance.
•
Regularly check the system for presence of leakage and the oil level.
•
During system's function, it is necessary regularly to verify that the temperature of the ambient and
the operating oil are those initially determined.
•
Replenish and change the oil, the oil and air filters as stated in the respective instructions.
•
Regularly check the condition of the oil – viscosity, oxidation, filtration level etc.
Viscosity
Verify that the viscosity level is within the recommended values as indicated in
Viscosity and temperature for D1P pump
Oxidation
Mineral oil gets oxidized proportional to the usage degree and operating
temperature. The oxidation of oil is evident because of its change of color, bad
smell, acidity increase and because of the generation of sludge inside the tank.
In case symptoms of this kind are detected, the system oil must be immediately
changed.
Water presence
The presence of water inside oil can be determined by taking oil samples from
the bed of the oil tank: oil floats on water, if present, water tends to stay on the
tank's bed. If its presence is determined, water must be regularly purged.
Presence of water in the hydraulic system can severely damage the pump.
Degree of
A high degree of contamination of the operating oil causes a severe wear of all
contamination
hydraulic components: for this reason, the cause of the contamination must be
identified and eliminated. In order to avoid mixing of different oils, when
replacing the operating fluid. It is necessary to empty all the machinery and
pipes, clean them carefully and clean the tank.
