Débit: The main pump of the PC200 – 8 hydraulic system has a maximum flow rate of 439 l/min. Le 708 – 2L – 00490 pump is designed to meet this flow requirement to ensure the normal operation of the excavator's hydraulic components.
Pression: The working pressure of the hydraulic system of the Komatsu PC200 – 8 varies according to different working conditions. The maximum pressure of the main hydraulic system is generally 37.3 MPA, and the control hydraulic system is 3.2 MPA. Le 708 – 2L – 00490 pump needs to work stably within this pressure range.
Caractéristiques structurelles: It is likely to be a variable – déplacement axial – pompe à piston. The axial – piston pump has the advantages of high efficiency and good variable – performances de déplacement, which can meet the requirements of different working conditions of the excavator. Le corps de la pompe est en haute – acier allié résistant ou fonte, qui a une bonne tenue – résistance et corrosion – résistance. Les pièces mobiles internes, tels que les pistons et les plateaux oscillants, sont faits d'usure – Matériaux résistants pour assurer une longue durée de vie.
