Hakuteksti "fluid".

Basic design for a hydraulic drive in which the pump draws in the hydraulic fluid from a storage tank, the surface of which is open to atmospheric pressure. The oil is conveyed to the consumer via directional

pressure difference, the flow rate is also dependent to some extent on the viscosity of the pressure fluid.

Drive elements activated by an amplifying auxiliary force (e.g. power steering, servo brake). In fluid technology : Collective term for an automatic drive system, which contains a power amplifier and a

The main function of the filter is to hold back undissolved foreign particles in hydraulic fluid. This makes it an important part of any hydraulic system. The aim of filtering is that The wear on moving [...] control spools and therefore interruptions in operation are prevented; The ageing of the hydraulic fluid due to chemical processes as a consequence of contamination is slowed down. Filtration is more important

The flow rate distribution ensures a continuous fluid supply to the hydraulic consumers independent of the pump capacity. With the help of pressure compensation, the oil flow to the consumers is proportionally [...] undersupplied by the pump. Each valve section has its maximum flow rate. Without flow distribution, the fluid will choose the path of least resistance if the pump cannot provide the required flow. This can result

accordance with the size of the consumers and thus the overall need for fluid in the hydraulic system. The warming of the fluid, as well as potential leakages must be taken into consideration here. The [...] hydraulic power pack is a stand-alone assembly consisting of a drive motor, hydraulic pump and hydraulic fluid tank. The drive motor is connected to the hydraulic pump via a shaft and drives this. The motor and

Volume of fluid which flows through a cross-section in one time unit. In hydraulics the flow rate is generally stated in litres per minute (lpm). For example, filling a 10 litre water bucket at the tap

Ability of a hydraulic fluid to cover the surface over which it is distributed to a greater or lesser degree. Hydraulic fluids with good wetting ability adhere better to the surface. As a consequence the

loss is the most important source of loss in hydraulic systems. It arises due to the of the pressure fluid in the pipes and the devices, and also due to mechanical friction losses (e.g. in guides or at seals)

Characterises the number of particles present in hydraulic fluid . Purity classes are stated either in filter classes according to NAS 1638 — which specifies the permitted particle numbers in five particle
