The specific displacement value for the 21W-60-22111 and 705-40-01370 hydraulic piston pumps is not directly indicated by the part numbers. Given that the Komatsu PC75UU-2 is a small to medium-sized excavator, the displacement is likely to be in the range of 40 – 70 centimetri cubici per rivoluzione (cm³/rev). Tuttavia, the exact displacement should be obtained from Komatsu's official product documentation.
Pressione operativa
Pressione nominale: The rated pressure of this pump is typically around 200 – 250 sbarra (20 – 25 MPA). This pressure rating is designed to effectively drive the various hydraulic actuators in the PC75UU-2 excavator, ensuring smooth operation of functions such as arm movement, Funzionamento del secchio, and slewing.
Pressione massima: The maximum pressure that the pump can withstand for short periods is usually higher than the rated pressure, often reaching up to 300 sbarra (30 MPA) o più. This additional pressure capacity allows the pump to handle sudden high-load situations that may occur during the excavator's operation, such as when working in tough soil or rocky terrain.
