外观检查:启动前应进行外观检查。按以下顺序彻底检查机车周围和底部:
Visual inspection: visual inspection shall be conducted before startup. Thoroughly inspect the periphery and bottom of the locomotive in the following order:
是否有机油、燃油和冷却液泄漏。螺栓和螺母松动。电路是否有断线、短路、电池接头松动等。
Check for oil, fuel and coolant leaks. Bolts and nuts are loose. Whether the circuit is broken, short circuited, loose battery connector, etc.
开机后检查,
Check after startup,
扬声器和所有乐器状况良好。发动机启动状态、噪音和排气颜色。检查机油、燃油和冷却液是否泄漏。
The speakers and all instruments are in good condition. Engine start status, noise and exhaust color. Check for oil, fuel and coolant leaks.
燃料管理,
Fuel management,
应根据不同的环境温度选择不同牌号的柴油;柴油中不得混入杂质、石灰土和水,否则会使燃油泵过早磨损;劣质燃油石蜡和硫含量高,会对发动机造成损害;日常运行后,给油箱加满油,防止油箱内壁有水滴;发动机燃油用完或更换滤芯后,必须将道路中的空气排出。
Different grades of diesel oil shall be selected according to different ambient temperatures; The diesel oil shall not be mixed with impurities, lime soil and water, otherwise the fuel pump will be prematurely worn; Poor quality fuel with high paraffin and sulfur content will cause damage to the engine; After daily operation, fill the oil tank with oil to prevent water droplets on the inner wall of the oil tank; After the engine runs out of fuel or the filter element is replaced, the air in the road must be discharged.
滤芯的保养,
Maintenance of filter element,
滤芯的作用是过滤油路或气路中的杂质,防止杂质侵入系统造成故障;各种滤芯应按操作维护手册的要求定期更换;更换滤芯时,检查旧滤芯是否有金属附着。如果发现金属颗粒,及时诊断并采取纠正措施。使用符合机器要求的纯滤芯。
The function of the filter element is to filter the impurities in the oil circuit or gas circuit to prevent the impurities from invading the system and causing failure; Various filter elements shall be replaced regularly according to the requirements of the operation and maintenance manual; When replacing the filter element, check whether the old filter element has metal adhesion. If metal particles are found, timely diagnose and take corrective measures. Use a pure filter element that meets the requirements of the machine.
