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)

In hydraulic fluid removal of the air carried and separated out. This must take place at the highest point with the aid of bleed screws or bleed valves.

rate that a pump delivers. The term delivery flow should as far as possible no longer be used in fluid technology, instead flow rate should be used.

Compressed air filters that can retain particles of dirt down to 0.01 μm. This includes fluid particles of this size (e.g. aerosols), and also bacteria and viruses.

Resistance which a fluid flowing inside pipes or similar bodies must overcome. It is higher for laminar flow than for turbulent flow: where A S = flow cross section.

losses due to fluid friction are generally no longer negligible. The flow rate through the nozzle is, as on orifices, defined with the aid of Bernoulli's equation. The loses due to fluid friction and the

mostly a rectangular cross-section that is fastened to the shaft and to which a flow of hydraulic fluid is applied.

Fire-resistant hydraulic fluid based on esters of phosphates. It belongs to the group known as HFD fluids ; its fire resistance is can be explained by its molecular structure.

Fluid level height above an inlet or outlet opening. In the case of a negative inlet height, the suction pressure for pumps is lower than the ambient pressure (Figure Z 8).

In order for the hydraulic fluid to deliver sufficient lubricating effect in plain bearings and under seals , it must have sufficient wetting ability. This is generally the case with HLPD oils .
