The pump has a fixed displacement of 63 cm³/rev. This indicates the volume of hydraulic fluid displaced per revolution of the pump's drive shaft. A larger displacement generally means a higher flow rate at a given rotational speed, which is crucial for powering the various hydraulic functions of an excavator, such as boom, Arm, und Schaufelbewegungen.
Nenndruck
Der Nenndruck beträgt typischerweise 350 Bar. This is the maximum continuous pressure at which the pump can operate while maintaining reliable performance and the specified flow rate. In an excavator, this high – pressure capability is essential for performing tasks that require significant force, like digging into hard soil or lifting heavy loads.
Maximaler Druck
Es hält einem maximalen Druck von bis zu stand 400 Bar für kurze Zeit. This peak – pressure rating allows the pump to handle sudden load spikes or high – demand situations during excavator operation without immediate damage, although extended operation at this pressure may reduce the pump's lifespan.
Bewertungsgeschwindigkeit
The rated speed is around 1800 Drehzahl. Der Betrieb der Pumpe mit dieser Drehzahl gewährleistet eine optimale Leistung hinsichtlich der Fördermenge, Druckerzeugung, und mechanische Effizienz. Deviating significantly from this speed may lead to decreased performance, erhöhter Verschleiß, or potential damage to the pump components.
Durchflussrate
Bei der Nenngeschwindigkeit von 1800 Drehzahl, the theoretical flow rate is calculated as displacement × rated speed / 1000. Also, for the A10VO63 pump, the theoretical flow rate is 63×1800÷1000 = 113.4 L/min. Jedoch, the actual flow rate may be slightly lower due to internal leakage and other factors, normalerweise in der Nähe 95 – 98% des theoretischen Wertes.
