the permissible final pressure difference is reached at the rated flow rate QN: γ = contamination with ACFTD in the flow rate, Q = flow rate through the filter, τ = test time until the permissible final [...] dirt holding capacity". It is used to compare the service life of filter elements of the same size with the same β value. The α values is a calculated variable that does not take into account if the filter [...] performance the numerical value for α is very high. It must therefore always be evaluated in conjunction with the filter cumulative efficiency , otherwise it will cause confusion. See also dirt holding capacity

bar/s and defines, e.g. on pumps, the amplitude of the pressure pulsation-induced oscillations and with it also the amount of noise.

Hydraulic pump/motor with two or more gears working together in one housing. They may take the form of an external geared pump/motor , an internal geared pump/motor or an annular gear pump/motor .

Double-acting cylinder with two piston rods. The velocity is the same in both directions if both piston rods are the same thickness and the same flow rate acts on both piston areas. ( Hydraulic cylinders

Gas pressure that is applied to a fluid vessel with or without separator. On hydraulic accumulators the gas filling pressure corresponds to the precharge pressure. Example: hydropneumatic accumulator

time the transmission ratio of the pressure amplifier. It is possible to operate with the same pressure fluid and also with different pressure fluids (e.g. compressed air/ oil) in the two pressure systems

torque. Rolling & sliding friction is rolling friction with an overlaid sliding component (slip). Spinning friction is the dynamic friction with relative rotation around an axis turning perpendicular to

ignored. Constant flow systems in an open circuit are therefore always fitted with constant pumps (in a closed circuit, with a variable pump ) and can only operate one load at a time ( Figure K 30 ). If

Ability of a filter to retain specific test contamination in a hydraulic fluid with a specified contamination concentration under defined test conditions (CETOP RP 100). As the test method for filtration [...] general the multipass test according to ISO 4572 has become established. However, the results obtained with this test cannot be simply transferred to practice, as in relation to the conditions during the test

pressure-signal function , e.g. 2,000 bar/mA. It is crucial for the accuracy that can be achieved with a controller.
