Resistance of a liquid to permanent changes of its properties in normal storage and load conditions (CETOP RP 100).

Modified HLPD oils that only take on (hold) a water content of 1 to 2%, but separate larger water quantities –– like any normal mineral oil . The stabilised hydraulic oils therefore only slightly redu

The complex ratio of the control coil voltage and current. The coil impedance is a function of the frequency of the signal amplitude and other operating conditions, but it can be estimated using the O

Hydraulically actuated directional valve that ensures in a closed circuit that the oil brought into the circuit by the Flushing pump is once again flushed out on the respective low-pressure side.

Charge pump

During the initial commissioning or repeat commissioning, every hydraulic System must be flushed to remove residual foreign particles (shavings, scale or other contamination) from the system. The flus

Pressure at the point at which the flushing current leaves the flushed circuit ( feed circuit ) (DIN 24 312).

Hydraulic power pack, consisting of a hydraulic pump and a large Filter with a fineness of 10 or 25 μm, which is used in the main flow to remove the built-up dirt in a hydraulic system before it is ac

Function, which changes its value by a predetermined value suddenly at a defined time t. The change of the caused by this is called the . A step function is used, for example to determine the of a con

Pump piston with a spherical piston surface, which contains piston rings for sealing. The piston shaft is lowered ( Figure S 75 ). The spherical piston is used in axial piston machines, in which the c
