Piping and hoses and the type of routing (pipe length, line
cross-section, number of bends, height differences, etc.) influ-
ence the pressure loss in a hydraulic system. These were dis-
regarded in the example shown above.
5.3 Avoiding the mixing of oils - Emptying the filter unit
If you want to use the same oil for operation as in the previous
operation, the mixing of oils is not critical.
If you do not know which oil was previously filtered with the fil-
ter unit, replace the filter element and empty the filter unit com-
pletely in order to prevent mixing with the residual oil in the fil-
ter unit.
If different oils are mixed, the oil properties can change nega-
tively as follows:
– Higher risk of cavitation
– More seal wear
– Modified anti-wear properties
– Poorer filtration
– Reduced filter element service lives
– Modified friction characteristics
– Modified response to water
– More deposits due to additive reactions
– More system contamination due to detached deposits
– Changed water/air absorption and air release behavior
– Greater tendency to foam
