在JL1075联合收割机上,6359TZ02型发动机柴油油路中串联使用了3个输油泵,使其低压油路的压力比一般柴油机要高一些。这是因为它的高压油泵采用了分配式喷油泵,而且发动机转速高,功率大。下面介绍一下各个输油泵的使用保养要点: (1) 电磁输油泵安装在油箱下方,当主开关钥匙插入后,电磁输油泵就会发出“哒哒”的响声,向喷油泵供油。在使用中每隔250小时就要清洗 In the JL1075 combine harvester, 6359TZ02 engine diesel oil in series with the use of three pumps, the pressure of its low-pressure oil to higher than the average diesel engine. This is because of its high-pressure pump with a distributed fuel injection pump, and the engine speed, high power. The following describes the use of oil pump maintenance points: (1) electromagnetic pump mounted on the bottom of the tank, when the main switch key is inserted, the electromagnetic pump will issue a “da da” sound, to the fuel injection pump. In use every 250 hours to be cleaned
