Ohne spezifische Komatsu-Produktdokumentation, it's difficult to determine the exact displacement precisely. Jedoch, for hydraulic piston pumps used in Komatsu excavators like the PC200 series, the displacement is a crucial parameter. Es kann normalerweise zwischen variieren 100 Zu 200 Kubikzentimeter pro Revolution (cm³/rev). Ein höherer Verdrängungswert ermöglicht es der Pumpe, mehr Hydraulikflüssigkeit pro Umdrehung zu bewegen, Dies ist für Antriebsfunktionen wie das Anheben des Auslegers unerlässlich, Armbewegung, and bucket operation in these excavators.
Betriebsdruck
Nenndruck: These pumps are designed to operate at high pressures to meet the demanding requirements of excavator operations. The rated pressure for the 708-2L-00460 and 708-2L-00300 pumps is likely to be in the range of 280 Bar (28 MPA) Zu 350 Bar (35 MPA). This pressure range enables the pump to stably supply power to the hydraulic system, driving various hydraulic actuators effectively.
Maximaler Druck: The maximum pressure that the pump can withstand in a short period is usually higher than the rated pressure. Es kann herumreichen 380 Bar (38 MPA) Zu 420 Bar (42 MPA), depending on the design and application of the pump. When the excavator encounters sudden high loads or extreme working conditions, the pump needs to handle such high pressures briefly.
