Pre-filter
Relatively coarse compressed air filter (fineness approx. 3 μm ), which is placed upstream of high-performance filters in the case of dusty air to increase its service life. Pre-filters are generally
Residual contamination
Quantity of contamination in the hydraulic fluid after filtering . This is currently mainly measured and counted using automatic counting devices. The result is a profile of contamination in accordanc
Piping
Casual term for laying the pipelines necessary for a system. As a rule, it is performed by the assembly operator after a visual inspection during assembly or pre-assembly. In the case of complex syste
Hydro-mechanical signal converter
Converts mechanical from an electro-mechanical into hydraulic signals. This is mainly achieved by throttling an oil flow with controllable mechanical resistors or transforming the kinetic energy of an
Transfer signal
Signal, which transfers a certain result of a processing unit to another processing unit. It is a case of: parallel transmission if the transfer signals are passed on simultaneously and parallel to th
Fluid power systems with main pipe
Within a larger system several loads (drive elements) are supplied by one drive power pack. The fluid power system with main pipe can combine such loads, which do not interact, because e.g. they come
Accumulator regulations
Accumulators, which are increasingly used in hydraulics in the form of hydraulic accumulators , are considered dangerous systems due to the high (gas pressures) that occur inside them and require spec
Plug-in connection
Connection for hoses in accordance with DIN 20 043, which is quick to fit without the use of tools and can be detached.
Stability criteria
Mathematical conditions, which must be fulfilled so that a system capable of oscillation takes on a stable state. A distinction is made between necessary and sufficient conditions. The stability crite
