我公司用户2004年购入的1台沃尔沃L330E型装载机,其自重为50.7t,斗容量为6.7m~3,配置D16B型柴油机,最大功率为368kW。该机夏季在南方某矿山进行装车作业时,其柴油机水温过高,且变速器、制动器和液压系统油温也过高。根据该机特点,其冷却系统和液压系统均可影响工作温度。现结合这2个系统结构和工作原理,查找故障原因。
My company users in 2004 purchased a Volvo L330E-type loader, its weight is 50.7t, bucket capacity of 6.7m ~ 3, configuration D16B diesel engine, the maximum power of 368kW. The aircraft in the south of a mine in the summer loading operation, the engine temperature is too high, and the transmission, brakes and hydraulic system oil temperature is too high. According to the machine features, the cooling system and hydraulic system can affect the operating temperature. Now combined with the two system structure and working principle, find the cause of the malfunction.
