Fluid Sampling Set properties
Compliance with and regular monitoring of the particle load in fluid and lubrication
technology is essential for efficient, economical system use.
Static and dynamic sampling for later fluid analysis can be carried out using very
simple means with the Fluid Sampling Set FES.
NOTE
The FluidAnalysis Set may only be used with mineral oils.
Contact us prior to using with other operating fluids.
Source of oil contamination
Contamination of hydraulic media is classified according to the particular physical
state:
Solid
Gaseous
and liquid contamination.
Solid particles enter the hydraulic system because the unit is inadequately sealed,
through maintenance work or new oil, for example. Once present, these particles
produce new ones, leading to a "chain reaction of wear".
Gaseous contamination often results from leakage on the suction side of hydraulic
pumps, poor return flow of the medium to the tank or when pipelines must be
opened (e.g. for maintenance work).
Hydraulic media water contamination can either be caused by condensation or
penetration. The condensation of water is caused by temperature differences in the
hydraulic reservoir. Water can enter through faulty cooler hoses, faulty seals or a
leaky reservoir. Water-absorbent filter elements (filter fineness 3 ... 40 µm) can also
be used for the removal of free water.
