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

reciprocal of the Kompressionsmodul K. The value of K can be assumed to be 1400 MPa for a hydraulic fluid. Calculate the volume reduction on pressure increase directly and easily in our hydraulic calculator

Damage to the hydraulic fluid primarily due to oxidisation (formation of acid residues) and polymerisation (enlargement of the hydrocarbon chains); creates sludge or resin-like coatings on device parts

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

Newtonian fluids, the flow rate through these kinds of flow resistors is mainly determined by the viscous fluid friction, geometry and pressure difference and may be calculated fairly accurately using Hagen-Po

(depending on the shape of the cross section), a laminar flow will apply. The individual elements of the fluid only move in the direction of the flow. As a result of viscosity, the local velocity across the cross

components are generally more vulnerable than fluid parts, the redundancy measures in fluid technology are focused on signal distribution . However, fluid systems may also have a redundant design. In doing

Unit for pressure: 1 bar = 105 N/m2 The unit "bar" is frequently used in modern fluid technology, as that way the traditional numerical values can still be used for pressures. In SI units the unit "pascal"

Since the pressure in a fluid is the same at every point (laws of hydraulics), the force generated is solely dependent on the size of the area on which the pressure is acting. It is possible therefore

Static pressure at which a pipe or pipe connection is destroyed such that hydraulic fluid escapes (DIN 24 312). This definition should also be applied to the filter bursting pressure for the filter housing
