      With the advent of summer, the high temperature climate is constantly added. The construction in the concrete mixer needs to do a good job of preventing high temperature, so as to prevent the machine from failing and do a good job of heatstroke prevention for workers. The following section will talk about the emergency treatment of "heatstroke" of the mixer engine.
      1. Engine water temperature is too high
      There are many reasons for abnormal circulation of the cooling system, such as thermostat, cooling silicone fan, fan belt, etc., which cause the cooling system to fail to work normally.
      Keep the engine on, and do not stop the engine; Water the radiator surface with cold water to accelerate cooling. In this case, the temperature of circulating water is limited. When the engine temperature is below 80 ℃, the engine will shut down intermittently, step on the flameout switch or unplug the sensor of the EFI system, and use the starter to drive the engine to run. 10-15 seconds is an operating cycle. The engine will be cooled by passive operation, and then check whether the oil dipstick scale is within the normal range.
      Tip: Never unscrew the water tank cap before the engine is completely cooled down.
      2. The engine is overheated and the cooling system is normal
      The engine temperature is overheated after overload, but the cooling system can still operate normally.
      At this time, the engine shall be kept idling, and it is forbidden to shut down; Water the radiator surface with cold water to accelerate cooling. When the temperature drops to about 50 ° C at idle speed, unscrew the water tank cover with a soaked thick towel to cool down. After that, be sure to check whether the oil dipstick scale is within the normal range.
      Tips: People should avoid facing the water tank cover directly to prevent scalding by water spray.


      3. Coolant leakage or loss
      Engine "dry burning", that is, running without cooling water, may cause very serious accidents. At this time, any cooling water pouring on the radiator is basically ineffective, and the engine cannot dissipate heat when running.
      When the vehicle is parked, the engine oil filler shall be opened and the lubricating oil shall be filled quickly. This is because the engine lubricating oil will evaporate with a large amount of high temperature under the condition of water shortage and must be replenished quickly.
      The next step is very important. After adding lubricating oil, turn off the engine and cut off the oil. Run the starter at the same time and run the engine passively. It can run for 10 seconds and pause every 5 seconds to maintain this frequency. It is better to damage a starter, but also to keep the engine, so as to avoid serious accidents such as cylinder sticking and cylinder pulling to a large extent.
      In addition, the fire prevention of concrete mixer shall also be done well. The hot and hot climate is dry. Fire extinguishers and other fire-fighting equipment shall be checked, and the emergency plan for concrete mixer shall be prepared.
