Automatic feeding mixer in peacetime to carry out regular maintenance, this is a lot of people know. But you know that maintenance is also needed during transportation.
In the early stage of engine operation, the water temperature is very fast; when the water temperature gauge indicates 80, and the heating rate slows down, it indicates that the thermostat is working normally. On the contrary, if the water temperature always increases rapidly, when the internal pressure reaches a certain degree, boiling water suddenly overflows, indicating that the main valve is stuck and suddenly opens. When the water temperature gauge indicates 70 ℃ - 80 ℃, turn on the radiator cap and radiator drain switch, feel the water temperature by hand. If both hands are tight, the thermostat works normally; if the water temperature at the radiator water inlet is low, and there is no water outflow or little water flow from the water inlet pipe of the radiator upper water chamber, it indicates that the main valve of the thermostat cannot be opened. If the thermostat is stuck or not closed tightly, it should be removed for cleaning or correcting, and should not be used with palliative care.
Using the communication method, remove the air filter of the engine. Assuming that the automatic charging mixer claims that the machine does not emit black smoke, it means that the air filter is seriously blocked. The blockage should be eliminated. Maybe the filter element should be changed and the effect of changing the new filter element is very good. Due to the improper adjustment of the engine fuel injection pump and governor, the fuel injection quantity of the nozzle is too large, which exceeds the fuel injection quantity of each cycle of the engine. Perhaps there is a relatively serious phenomenon of rear drip, which constitutes the excessive fuel supply.

For the diesel engine with automatic charging mixer equipped with turbocharging equipment, the diagnosis and cleaning shall be conducted intermittently according to the defect diagnosis method of turbocharging equipment in the repair code, or the replacement method shall be used, that is, the same type of turbocharger shall be replaced. If there is no black smoke after communication, it can be proved that the black smoke of diesel engine is caused by the damage of turbocharger. Diesel oil is hydrocarbon. If the engine stops under the condition of short oxygen, the simple composition of the engine is not enough. If the stop is not enough, it will lead to the formation of free carbon from some carbon elements without lack of oxygen, which will be mixed into the exhaust gas to exhaust, resulting in the occurrence of black smoke.
Open the radiator filler cap. If the cooling water in the radiator is quiet, it indicates that the thermostat is working normally; otherwise, it indicates that the thermostat is working abnormally. This is because when the water temperature is lower than 70 ℃, the expansion cylinder of the thermostat is in the condition of shortening, and the main valve is closed; when the water temperature is higher than 80 ℃, the expansion cylinder expands, the main valve gradually opens, and the circulating water in the radiator is initially activated.
In the process of using the automatic feeding mixer, the paint surface shows the phenomenon of metal surface exposure due to small heart collision without timely correction. During this period, the paint surface should be cleaned frequently, otherwise the injury level at the "wound" will be aggravated. However, to pay special attention, it is necessary to clean the paint surface, but repair work, should try to prevent the choice of interruption in the wet period.
The automatic feeding mixer is not only for maintenance after parking, but also for maintenance during transportation. We should pay more attention to these two aspects.
