Considerations on switching methods for hydraulic pumps are necessary if several pumps are used in a hydraulic system . A distinction is then made between ( Figure S 17 ): two-circuit or multi-circuit

Fixture which changes the flow rate of a variable pump in such a way that is becomes ever smaller as the pressure increases (e.g. up to around 5% of Q max). The pressure at which adjustment starts is

Toroidal ring made of elastic materials, with an almost square cross-section ( Figure Q 1 ).

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 p

Filter located in the direct circuit and through which therefore the entire and, for the most part, periodically pulsatile flow rate passes. Filters in the main conduit include the following: Suction

During the initial commissioning or repeat commissioning, every hydraulic System must be flushed to remove residual foreign particles (shavings, scale or other contamination) from the system. The flus

Adjustment system for double pumps with an equally high flow rate, whose adjustment devices are mechanically or hydraulically coupled and which transport the flows in two different circuits with diffe

Sealing friction

Hydraulic control circuit for which the input signal (distance, rotation speed) is specified using mechanical means via a hand lever, cam disc or spindles and the like, before being hydraulically ampl
