夏天来临，跟着高温气候也不断添加，在混凝土搅拌机中施工需要做好防高温的工作，这么可以防止机器出现毛病和做好工作人员的防暑工作。下面小编来讲讲搅拌机发动机“中暑”的应急处理。

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、发动机水温过高

1. Engine water temperature is too high

冷却系统循环出现异常的原因有很多，例如节温器、冷却硅油风扇、风扇皮带等损坏导致冷却系统无法正常工作。

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.

要保持发动机着车状态，严禁熄火；用冷水浇散热器表面加速降温。通常这类情况下，循环水温度下降有限，在发动机温度80度以下，采取间断熄火，踩下熄火开关或者拔掉电喷系统传感器，用启动机带动发动机运转，10-15秒为一个运转周期，被动运转降温，后检查机油尺刻度是否在正常范围内。

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.

小贴士：在发动机完全冷却之前，切记无论何时都严禁拧开水箱盖。

Tip: Never unscrew the water tank cap before the engine is completely cooled down.

2、发动机过热，冷却系统正常

2. The engine is overheated and the cooling system is normal

负荷过载后的发动机温度过热，但冷却系统仍可正常运行。

The engine temperature is overheated after overload, but the cooling system can still operate normally.

此时应保持发动机怠速运转，严禁熄火；用冷水浇散热器表面加速降温。在温度下降50度左右的怠速状态下，用浸湿的厚毛巾旋开水箱盖，进行降温。后一定要检查机油尺刻度是否在正常范围内。

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.

小贴士：人应避免正对水箱盖，以防喷水烫伤。

Tips: People should avoid facing the water tank cover directly to prevent scalding by water spray.

3、冷却液发生遗漏或散失

3. Coolant leakage or loss

发动机“干烧”，也就是无冷却水状态下运转，可能造成非常严重的事故。这时采用任何冷却水浇散热器的方式降温都基本无效，发动机运转也无法散热。

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.

着车状态下，应打开机油加注口，迅速加注润滑油，这是因为在缺水状态下，发动机润滑油会随之大量高温蒸发，须迅速补充。

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.

下一步非常重要，加完润滑油须熄火断油。同时运转启动机，被动运转发动机。可持续10秒运转，间隔5秒停顿，保持此频率。宁可损坏一个启动机，也要保住发动机，大程度避免粘缸，拉缸等严重事故。

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.

此外也要做好混凝土搅拌机的防火工作，高温炽热气候枯燥，应检查灭火器等消防器材，做好混凝土搅拌机的应急预案。更多相关事项就来我们网站http://www.zkhntjbc.com进行咨询。

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.
