hydrostatic load-bearing layer it is applied from the exterior. The fluid friction is produced in both cases by the internal friction in the fluid that forms the load-bearing layer (DIN 50 281).

concepts. The control concepts used in fluid technology only constitute one part of all the possible variations. Due to the unfavourable framework conditions in fluid technology in terms of control technology

also only makes itself apparent where the mass forces of the flowing column of fluid have an effect. As hydraulic fluids are in reality not incompressible, but are compressible, in addition to the energy [...] The basis is Bernoulli's equation for ideal, incompressible fluids: = static pressure + dynamic pressure + geodetic pressure. This equation yields the related energy element as The last term ρ · g · h

Compressibility

Hydraulic spring constant

Resistance of a liquid to changes in viscosity under shear stress (CETOP RP 100).

readily biodegradable hydraulic fluids are used. These fluids can be produced from mineral oil or using renewable materials. They are also referred to as bio-based hydraulic fluids. [...] the hydraulic fluid conducts away the locally occurring heat and takes with it contamination, which is caused by debris, for example. For this task, mineral oils and flame-resistant fluids are available [...] Hydraulic fluids have the task of transporting hydraulic energy from the location of generation (pump) to the location of conversion ( cylinder , motor) with the minimum possible losses. They are also

In hydraulics a differentiation is generally made between four pressure ranges within which the allocation of pressures is however a little scattered: Low pressure (LP): Pressures up to approx. 100 ba

Generic term in fluid technology for hydraulic fluids ( hydraulics ).

Responsibility for working on and drafting standards for fluid technology lies with the specialist fluid technology department at the Normenausschuss Maschinenbau (Standards Committee Mechanical Engineering [...] NAM). They work on all DIN, ISO and DIN ISO standards. In addition, recommendations with regard to fluid technology are also provided by CETOP and VDMA, and there are VDI guidelines too. A very comprehensive [...] uch 1993/1994" [O+P Design Manual 1993/1994] published by Vereinigte Fachverlage. The specialist fluid technology committee at the VDMA has also produced an overview.
