近日,徐工挖掘机再获24项专利授权,包括大型工程机械下车架顶板结构、挖掘机独立散热系统双向控制安全阀、基于CAN-BUS的工程机械电气控制系统、液压挖掘机发动机独立散热风扇驱动系统等。其中,液压挖掘机发动机独立散热风扇驱动系统专利技术已成功应用于XE900C型和XE1300C型两款大型液压挖掘机,成功解决了发动机直驱散热系统带来的散热匹配范围窄的问题,提高了燃油经济性,降低了噪声。
Recently, XCMG excavator re-won 24 patents, including large-scale construction machinery under the roof structure, excavator independent cooling system two-way control safety valve, based on CAN-BUS construction machinery electrical control system, hydraulic excavator engine independent cooling fan Drive system and so on. Among them, the hydraulic excavator engine independent cooling fan drive system patented technology has been successfully applied to XE900C and XE1300C type two large hydraulic excavator, the successful solution to the engine direct-drive cooling system to bring the heat to match the narrow range of issues and improve the fuel Economical, reducing noise.
