through slight swelling, to complete dissolution of the elastomer. If the DVI of the intended hydraulic fluid is known, with the aid of diagrams it is possible to determine the expected volume change (Figure

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 accordance

ics, the transmission of energy mainly occurs via the kinetic energy associated with the flowing fluid. This is why, compared with hydrostatics , flow velocities are high and pressures are low.

that is produced when two surfaces rub against each other. Friction can vary very significantly in fluid technology, depending on Which seal material is used, Which seal shape is used, The magnitude of the

Sum of losses arising in a fluid system. It is comprised of the pressure losses caused by mechanical and hydraulic friction and flow losses , leakage losses , throttle losses , which generally constitute

Device used to control or the output of the fluid by influencing the start, stop and direction, as well as the pressure and/or flow rate of the pressure fluid acting in the system ( Figure V 3 ). Valves

the length lp and the diameter dp of the line as well as from the density ρ and the speed of the fluid vf. Calculate the pressure loss in lines directly and easily in our hydraulic calculator .

with the generation and transmission of energy and signals via the static pressure associated with a fluid. This is why, compared with hydrokinetics , the pressure ranges are relatively high and the flow

circuits or in the control oil supply of pilot stages. Protective filters do not clean the pressure fluid and therefore their filter unit (β-value) should be more coarse than cleaning filters.
