Without specific product documentation from Dan Foss or John Deere, Es ist schwierig, den genauen Verschiebungswert zu bestimmen. Jedoch, for hydraulic piston pumps used in excavators like the John Deere 872G, the displacement is a crucial parameter. Es kann normalerweise zwischen variieren 100 Zu 300 Kubikzentimeter pro Revolution (cm³/rev). A higher displacement enables the pump to deliver more hydraulic fluid per revolution, Dies ist für Antriebsfunktionen wie das Anheben des Auslegers unerlässlich, Armverlängerung, und Schaufelbedienung im Bagger.
Betriebsdruck
These pumps are designed to operate at high pressures to meet the demanding requirements of excavator operations. The maximum operating pressure for the Dan Foss 872G hydraulic piston pump assembly (with model numbers 83041431 and AT457670) in the context of the John Deere 872G excavator is likely to be in the range of 250 Bar (25 MPA) Zu 400 Bar (40 MPA). This high pressure is necessary to drive the large hydraulic cylinders and motors that perform the heavy-duty tasks of the excavator.
