| Abstract: | Based on the power loss analysis of excavator hydraulic system, the causes and hazards of hydraulic system overheating are explored. According to component energy loss and the system input power and effective output power of executive components, the hydraulic system heat production is calculated. Taken into at.count the large heat production of excavator and based on the heat balance, the heat dissipation of mailbox and cooler is ealeulated. |
