Hakuteksti "fluid".

Ratio between the direction of the controlled hydraulic fluid flow and the direction of the electrical input flow for continuously adjustable valves.

To remove particles of dirt that the pressure fluid is carrying with the aid of filtration of a wide range of types.

characteristics of a fluid or adds new characteristics (CETOP RP 100). The natural substance mineral oil is lacking a series of characteristics for its tasks as a hydraulic fluid; these characteristics

Fluid valve with binary behaviour, i.e. it moves from one switching position to another (e.g. Open – Closed) without adopting an intermediate position.

Hydraulic speed control during which the hydraulic fluid flowing out of the actuator is throttled, e.g. by a flow valve in the return pipe.

element. The column of fluid has resistive behaviour, if the internal damping is ignored (acoustic impedance only has a real element). The acoustic impedance of a column of fluid in a pipe is dependent [...] achieved if the acoustic impedance of the pipe termination is the same as the impedance of the pipe (fluid + pipe walls). The acoustic impedance is used in hydraulics in particular for the design of pulsation

Line which returns leaked fluid to the container. Its dimensions should ensure this is possible at all times with hardly any pressure — even at low temperatures.

Contamination of the hydraulic fluid in a hydraulic system prior to the first flushing. It comprises the contamination that is in the hydraulic fluid itself prior to filling the hydraulic system and the

Device for measuring pressure levels in fluid media. They may function directly (e.g. vertical column pressure gauge ) or indirectly, whereby elastic deflections, for example, are used to record the pressure [...] pressure level. The pressure gauges used in fluid technology almost always operate indirectly via measuring devices with a spring, whose deflections are relayed to a pointer. In terms of the structure,

During the operation of a hydraulic system the particles of dirt that occur in the pressure fluid . They are either Added from the outside, e.g. due to leaks, a poor breather filter or are due to inadequate [...] are metal chips as well as abraded material from the seals or Ageing products from the hydraulic fluid (sludge among others). Sometimes there can also be water (that has entered the system or condensation)
