1.故障现象我公司空箱堆高机大都配置瑞典沃尔沃遍达公司(Volvo Penta)生产的TAD720VE型柴油机,该型柴油机存在燃油泵胶带容易断裂故障。我们统计,其燃油泵胶带使用寿命不足1000h。燃油泵胶带断裂后,会造成燃油泵、水泵、曲轴及发电机胶带轮磨损,严重降低了空箱堆高机利用率,给码头、堆场生产造成不良影响。为此,我们着手研究延长该型柴油机燃油泵胶带使用寿命的方案。2.原因分析TAD720VE型柴油机胶带轮分布及传动走向
1. Symptom Most of our empty stacker machines are equipped with the TAD720VE diesel engine manufactured by Volvo Penta Sweden. This type of diesel engine is prone to breakage of the fuel pump tape. Our statistics, the fuel pump tape life less than 1000h. After the fuel pump tape breaks, the fuel pump, water pump, crankshaft and generator belt pulley will be worn and severely reduce the utilization rate of the empty container stacker and adversely affect the terminal and yard production. To this end, we set out to extend the life of this type of diesel fuel pump tape program. 2. Reason Analysis TAD720VE type diesel engine pulley distribution and transmission direction
