hydraulic energy is in general produced by hydraulic pumps, the conducting section, comprising and fluid power control devices (control elements) and the motor section in which the hydraulic energy is converted

The details relating to the nominal size of devices used in fluid technology are key variables which do not refer to units or dimensions and do not have to be associated with any numerical variable for

from resonating. Measures to reduce the transmission of pressure and flow rate fluctuations in the fluid. This includes the use of hydraulic accumulators or expandable hoses for oscillation damping and silencers

Vessel for collecting and to some extent conditioning hydraulic fluid (removal of contamination and air, quietening). Is used at the same time to remove dissipated heat , however it is only suitable for

= 1.2*v m . As of a certain flow speed, which depends on the pipe diameter and the viscosity, the fluid becomes heavily swirled (turbulent) and this results in a high energy loss. This flow should generally [...] depends on the Reynolds number . As the formation of a laminar flow requires a build-up distance of the fluid flow pattern l a = 0.03 d i · R e (for example 20 mm internal pipe diameter approx. 1.3 m) compared

gear wheels with teeth on the outside that rotate engaged in each other. As a result the hydraulic fluid is pressed out of the gaps between the teeth on the outlet side, while the necessary vacuum is produced

series circuit) of several subsystems: For example, one subsystem is the plant to be influenced, in fluid technology this is often a cylinder with a connected load, the second subsystem is the immediately

accommodated based on the pressure increase required. It is a function of the compressibility of the fluid. The compressibility of the oil in a pipe is increased by the elasticity of the walls and any undissolved

the pressure of the medium (elastomer seals). These sealing elements are predominantly elastic in fluid technology and made of elastomers or thermoplastics (materials for seals). In addition metal seals

a symmetrical velocity profile will form ( Figure S 101 a ), which is caused by adhesion of the fluid to the surface. The flow rate/pressure characteristic is described by Hagen-Poiseuille's law ( Circular
