The high temperature and high heat summer is coming soon. Pedestrians on the road can not go out, but as our money making tool, the self loading cement mixer needs to go out. If the temperature is high, it will cause all kinds of small problems of our self loading cement mixer. Today, we will explain to you how to deal with the high temperature of the engine of the self loading cement mixer.
1. The engine is high temperature, but the coolant is not reduced
That is to say, the engine of the concrete mixer is overheated, but the cooling system works normally. At this time, the engine should be kept running at idle speed. It is strictly prohibited to turn off the engine. Pour cold water on the radiator surface to accelerate the cooling. When the temperature drops to about 50 ℃, unscrew the water tank cover with a wet towel to reduce the temperature. After that, check whether the scale of the oil dipstick is within the normal range.
2. The engine water temperature is too high and the cooling system circulation fails
There are many reasons why the engine water temperature is too high and the cooling system circulation fails. For example, the thermostat, cooling silicone oil fan, fan belt and other damage cause the cooling system to fail to work normally. First, keep the engine idling and cool the radiator with cold water. When the engine temperature drops below 80 ℃, stop the engine intermittently, step on the ignition switch or unplug the sensor of the electronic injection system, and drive the engine to run with the starter. 10-15 seconds is an operation cycle. The building operates to cool down, and then check whether the scale of the oil dipstick is within the normal range.
3. The coolant is missing or lost, and the engine cooling system is in dry burning state
If the engine operates without coolant, especially in summer, it will cause serious accidents. At this time, it is ineffective to use any cooling water to cool the radiator, and the engine cannot dissipate heat.
At this time, when the engine is idling, open the oil filler and quickly fill the lubricating oil. This is mainly because under the condition of water shortage, the engine lubricating oil will evaporate at high temperature and must be replenished quickly; After the lubricating oil is added, the engine must be shut off. Take any method to shut down the engine and cut off the oil. At the same time, operate the starter and passively operate the engine. The engine can run for 10 seconds continuously, with a pause of 5 seconds, and maintain this frequency. It is better to damage a starter than to keep the engine to avoid serious accidents such as cylinder sticking and cylinder pulling.
In view of the problem of "high temperature of the engine of the cement self loading mixer truck in summer", we analyzed the solutions to the following problems from three aspects. Therefore, we should also understand the solutions to the common faults of the mixer truck, so that we can deal with problems calmly and do not panic.
