hydraulic system of a country or bauwirtschaftlich usable machine

摘要

a hydraulic system of a country or bauwirtschaftlich usable machine with at least two consumers (13 and 15) is a closed center system trained with ecuseach consumer (13 and 15) are assigned in a central lastsignalleitung (8), a lastdrucksignal (pls) is generated.it is the hydraulic system in a verstellpumpe (2) whose conveying on a verstellzylinder (5)),with a druckwaage (6) is lastdrucksignal (pls) on this to form a first pressure difference (Δpls) with a pump pressure (pp) and a volume flow is comparable to the verstellpumpe (2) as a result of the pressure difference (Δpls) is adjustable.the creation of resources within a closed center system operated hydraulic system by which all consumers with leverage suppliedso that the required stellgeschwindigkeiten figure,to at least a in a primary circuit (12) positioned primary consumers (13), or at least in a secondary circuit (14) positioned secondary consumers (15) with optionalpressure from the verstellpumpe (2) are provided, with the hydraulic system, a second hydraulic pump (20) ison a system with at least one of such circuits (14) of the hydraulic system doors is that this is an emerging volumenstromdefizit ausgleichbar,and with a second hydraulic pump (20) outgoing secondary delivery pipe (21), at least one depending on a lastdrucksignal (pls2) betätigbares control (22) angeordnet is.
