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

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

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

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

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 .

rubber, including radial and shaft seal rings and O-rings. Not suitable for fire-resistant hydraulic fluids from the HFD group. Permissible temperature range -30°C to 100°C. Elastomers

motor in series connection, power-controlled pump, compressed air cylinder (connection behaviour of fluid drives). Opposite: position dependent locking , where it is possible to have an output variable which

Ratio of the mechanical output power P a to the fluid input power P e: It is comprised of the volumetric efficiency η 2vol, which is 100% in the case of non-leaking seals : and the hydromechanical efficiency

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.

Overload protection helps secure the system against excessive operating pressures. In fluid technology, the overload protection is provided by the working method of the pressure-limiting valve, which starts
