Where there is friction, there is wear. This also applies to seals . Here the wear depends on: The system pressure (seal is pressed against a surface); The surface roughness of the sliding surfaces (R

Branch of hydraulics . Concerned with the rules governing the flow of fluids with low compressibility and little internal friction. In hydrokinetics, the transmission of energy mainly occurs via the k

For fluid valves there are a number of actuation types: Manual actuation: Actuation using a hand or foot (including manual override). Mechanical actuation using levers, plungers and/or rollers and spr

In general : Device, which reduces the pressure (pulsation) fluctuations and therefore reduces the noise produced in connection with this, without preventing the transport of the fluid. In hydraulics

Viscosity of a hydraulic fluid at a defined temperature. This used to be +50°C according to DIN 51 502 and has been +40°C for a number of years now according to ISO 3448 (DIN 51 519). It is essential

Since actual fluids are compressible, they behave like a spring when pressure is applied to them: the higher the pressure, the more they are compressed and the smaller their volume becomes. The spring

Code in which the character string is formed based on defined specifications that makes it possible to detect deviations on these devices caused by malfunctions. The fault detection codes are redundan

The expression characterises the interaction of a throttle function ( throttle valve , continuous directional valve) with a (control throttle) that provides a load pressure independent flow rate with

Flow control valve

A distinction is made between "monotonous instability", when the system moves away from the initial position in a uniform manner following an impulse (Figure I 14 a) , and "oscillatory instability" wh
