夏天來臨，跟著高溫氣候也不斷添加，在混凝土攪拌機中施工需要做好防高溫的工作，這么可以防止機器出現毛病和做好工作人員的防暑工作。下面小編來講講攪拌機發動機“中暑”的應急處理。

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、發動機水溫過高

1. Engine water temperature is too high

冷卻系統循環出現異常的原因有很多，例如節溫器、冷卻硅油風扇、風扇皮帶等損壞導致冷卻系統無法正常工作。

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.

要保持發動機著車狀態，嚴禁熄火；用冷水澆散熱器表面加速降溫。通常這類情況下，循環水溫度下降有限，在發動機溫度80度以下，采取間斷熄火，踩下熄火開關或者拔掉電噴系統傳感器，用啟動機帶動發動機運轉，10-15秒為一個運轉周期，被動運轉降溫，后檢查機油尺刻度是否在正常范圍內。

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.

小貼士：在發動機完全冷卻之前，切記無論何時都嚴禁擰開水箱蓋。

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

2、發動機過熱，冷卻系統正常

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

負荷過載后的發動機溫度過熱，但冷卻系統仍可正常運行。

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

此時應保持發動機怠速運轉，嚴禁熄火；用冷水澆散熱器表面加速降溫。在溫度下降至50度左右的怠速狀態下，用浸濕的厚毛巾旋開水箱蓋，進行降溫。后一定要檢查機油尺刻度是否在正常范圍內。

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.

小貼士：人應避免正對水箱蓋，以防噴水燙傷。

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

3、冷卻液發生遺漏或散失

3. Coolant leakage or loss

發動機“干燒”，也就是無冷卻水狀態下運轉，可能造成非常嚴重的事故。這時采用任何冷卻水澆散熱器的方式降溫都基本無效，發動機運轉也無法散熱。

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.

著車狀態下，應打開機油加注口，迅速加注潤滑油，這是因為在缺水狀態下，發動機潤滑油會隨之大量高溫蒸發，須迅速補充。

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，加完潤滑油須熄火斷油。同時運轉啟動機，被動運轉發動機?？沙掷m10秒運轉，間隔5秒停頓，保持此頻率。寧可損壞一個啟動機，也要保住發動機，大程度避免粘缸，拉缸等嚴重事故。

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攪拌機的防火工作，高溫熾熱氣候枯燥，應檢查滅火器等消防器材，做好混凝土攪拌機的應急預案。更多相關事項就來我們網站http://www.wanyituangou.com進行咨詢。

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.
