During the use of the road roller, there will be more or less one kind of fault, which will affect the normal work. Therefore, it is necessary to clearly understand the common fault types and their causes, quickly and accurately determine the fault location, pay attention to the key points of maintenance, timely and efficiently eliminate hidden dangers, eliminate the impact of faults, and ensure the normal use of the roller. Next, we will analyze several common engine faults in detail.
(1) Reasons for difficult engine starting: insufficient battery power, falling off or poor contact of the starting circuit connector, starting motor failure, too little diesel in the fuel tank, or poor oil quality, causing fuel pipeline or filter blockage. Air entering the fuel system, etc.
(2) Reasons for the sudden flameout of the road roller during operation: the sudden flameout of the diesel engine during operation may be caused by the oil supply failure of the oil inlet pipe, the seizure of the transmission case, the seizure of the engine bearing bush, etc.
(3) Reasons for large amount of smoke when the engine is working: low temperature or poor fuel quality, engine overload, blocked air filter, poor air intake. Injection too late. Other reasons, such as wear of oil pump, oil nozzle, door, piston ring, etc.
(4) Reasons for high water temperature or oil temperature when the engine is working: the oil level in the crankcase is too low or the oil grade is incorrect. Thermostat failure. Insufficient cooling water or poor circulation. The fan belt is loose, the rotating speed is reduced, and the air volume is reduced. The thermometer or temperature sensor may fail, etc.
