Energy content of hydraulic fluid
pressure + geodetic pressure. This equation yields the related energy element as The last term ρ · g · h can generally be ignored in hydraulics, as it is mostly only a few tenths of a bar. The kinetic energy [...] away (e.g. on switching over a directional valve ), then the pressure in the still full chamber will be zero. The compression energy released during this process can be significant. Example: ΔV k = 1.0 L; [...] L; p = 300 bar; compression energy: 15 · 103 Nm. If this 1 L flows away in 0.5 s, a power of approx. 30 kW is released.
Hydrostatic traction drive
almost all torque is available, even at a low motor speed (= lowest accelerator pedal setting f 1) (Figure H 28) . This also applies to the braking torque. Using a limit load control prevents the combustion [...] or primary and secondary control (pump and motor control). If a suitable form of control is used (e.g. automatic control), the hydrostatic traction drive will be able to adjust to the power curves of the
