Searched for "fluids".

To monitor the state of a hydraulic fluid there are three variations, each with a different information value: Visual inspection : The colour of a pressure fluid (in particular mineral oil) is a measure [...] measure of its ageing. However, this is very inaccurate, as a black discolouration of the fluid alone does not necessarily affect its usability in any way. Quick analysis in operations : Ongoing control using

This situation marked the terminology in fluid technology for a long time. With the O+P-Fachlexikon "Fluidtechnik von A bis Z" (O+P technical glossary "Fluid technology from A to Z"), the 1st edition [...] and explaining the terms and names used in fluid technology. The lexicon triggered some productive discussion about terms and their technical context in the fluid technology sector and among users. University [...] Hydraulic and pneumatic drive and control technology – collectively termed fluid technology – is a comparatively young specialist area of drive and automation technology that only started to become used

Cleanliness level

of the hydraulic fluid of a hydraulic system. It can be caused by solid particles and/or dissolved foreign matter, by mixing with foreign liquids, or by air entering the hydraulic fluid. The solid particles [...] metallic surfaces. Therefore, hydraulic fluids must be filtered. Contamination with foreign liquids occurs through the entry of water, mixing with other hydraulic fluids or lubricants. The contamination may

Concerned with the physical characteristics and behaviour of fluids at rest (hydrostatics) and when moving (hydrokinetics)

Refers to the supply and discharge of the pressure fluid in pumps/motors through the inside of the displacement unit. For example, with valve plate controlled radial piston machines where the pistons are

Resistance of a liquid to permanent changes of its properties in normal storage and load conditions (CETOP RP 100).

uses the conversion, control, feedback control and transmission of energy by means of a fluid or gaseous hydraulic fluid to solve drive tasks.

Collective term for fluid and gaseous media. Here fluids is above all a common term for hydraulic fluids and compressed air.

Sound that propagates in a fluid medium. It can have been, but has not necessarily been generated in the fluid. The propagation velocity for mineral oil in steel pipes is approx. 1,300 m/s.
