我矿多年使用的一台ZL-40轮式装载机,在前一时期出现了液力变矩器油温过高的现象。每当装载机行驶或作业半个小时以后,变矩器的油温就会达到120℃,超过了该机规定的一般作业和行驶允许最高油温110℃。在对发动机风扇皮带、发动机水温、变矩器使用的油类油质、液压泵、变速箱油位、变速箱档位离合器工作性能等与变矩器油温过高有关的各个因素逐一检查分析和比
A ZL-40 wheel loader, which I used for many years in mine, experienced the phenomenon of excessive oil temperature in the torque converter during the previous period. Whenever the loader travel or work half an hour later, the torque converter oil temperature will reach 120 ℃, exceeding the machine’s general operation and driving the maximum allowable oil temperature of 110 ℃. In the engine fan belt, the engine temperature, the oil used in the torque converter, hydraulic pump, transmission oil level, gearbox clutch performance and torque converter oil temperature and other factors related to one by one inspection and analysis And than
