夏天來(lái)臨，跟著高溫氣候也不斷添加，在混凝土攪拌機(jī)中施工需要做好防高溫的工作，這么可以防止機(jī)器出現(xiàn)毛病和做好工作人員的防暑工作。下面小編來(lái)講講攪拌機(jī)發(fā)動(dòng)機(jī)“中暑”的應(yīng)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(fā)動(dòng)機(jī)水溫過(guò)高

1. Engine water temperature is too high

冷卻系統(tǒng)循環(huán)出現(xiàn)異常的原因有很多，例如節(jié)溫器、冷卻硅油風(fēng)扇、風(fēng)扇皮帶等損壞導(dǎo)致冷卻系統(tǒng)無(wú)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(fā)動(dòng)機(jī)著車狀態(tài)，嚴(yán)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(huán)水溫度下降有限，在發(fā)動(dòng)機(jī)溫度80度以下，采取間斷熄火，踩下熄火開(kāi)關(guān)或者拔掉電噴系統(tǒng)傳感器，用啟動(dòng)機(jī)帶動(dòng)發(fā)動(dòng)機(jī)運(yùn)轉(zhuǎn)，10-15秒為一個(gè)運(yùn)轉(zhuǎn)周期，被動(dòng)運(yùn)轉(zhuǎn)降溫，后檢查機(jī)油尺刻度是否在正常范圍內(nèi)。

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(fā)動(dòng)機(jī)完全冷卻之前，切記無(wú)論何時(shí)都嚴(yán)禁擰開(kāi)水箱蓋。

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

2、發(fā)動(dòng)機(jī)過(guò)熱，冷卻系統(tǒng)正常

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

負(fù)荷過(guò)載后的發(fā)動(dòng)機(jī)溫度過(guò)熱，但冷卻系統(tǒng)仍可正常運(yùn)行。

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

此時(shí)應(yīng)保持發(fā)動(dòng)機(jī)怠速運(yùn)轉(zhuǎn)，嚴(yán)禁熄火；用冷水澆散熱器表面加速降溫。在溫度下降50度左右的怠速狀態(tài)下，用浸濕的厚毛巾旋開(kāi)水箱蓋，進(jìn)行降溫。后一定要檢查機(jī)油尺刻度是否在正常范圍內(nèi)。

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(yīng)避免正對(duì)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(fā)生遺漏或散失

3. Coolant leakage or loss

發(fā)動(dòng)機(jī)“干燒”，也就是無(wú)冷卻水狀態(tài)下運(yùn)轉(zhuǎn)，可能造成非常嚴(yán)重的事故。這時(shí)采用任何冷卻水澆散熱器的方式降溫都基本無(wú)效，發(fā)動(dòng)機(jī)運(yùn)轉(zhuǎn)也無(wú)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(tài)下，應(yīng)打開(kāi)機(jī)油加注口，迅速加注潤(rùn)滑油，這是因?yàn)樵谌彼疇顟B(tài)下，發(fā)動(dòng)機(jī)潤(rùn)滑油會(huì)隨之大量高溫蒸發(fā)，須迅速補(bǔ)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(rùn)滑油須熄火斷油。同時(shí)運(yùn)轉(zhuǎn)啟動(dòng)機(jī)，被動(dòng)運(yùn)轉(zhuǎn)發(fā)動(dòng)機(jī)。可持續(xù)10秒運(yùn)轉(zhuǎn)，間隔5秒停頓，保持此頻率。寧可損壞一個(gè)啟動(dòng)機(jī)，也要保住發(fā)動(dòng)機(jī)，大程度避免粘缸，拉缸等嚴(yán)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(jī)的防火工作，高溫?zé)霟釟夂蚩菰铮瑧?yīng)檢查滅火器等消防器材，做好混凝土攪拌機(jī)的應(yīng)急預(yù)案。更多相關(guān)事項(xiàng)就來(lái)我們網(wǎng)站http://ffyhk.cn進(jìn)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. Come to our website for more information http://ffyhk.cn Consult.
