1、檢查排氣管路（排煙管最低處或消聲器）的排水構件是否有水排出。

Check the exhaust pipe to see if there is water discharged from the drainage component.

2、檢查空氣濾清器外殼是否有積水，濾芯是否被水浸漬。

Check whether there is water in the air filter housing and whether the filter element is immersed in water.

3、檢查發(fā)電機外殼底部是否有積水。

Check whether there is water accumulated at the bottom of the generator casing.

4、檢查散熱器、風(fēng)扇、聯(lián)軸器等回轉部件是否堵塞。

Check radiator, fan, coupling for blockage.

5、外部是否有機油、燃油或水的滲漏。

Whether there is leakage of organic oil, fuel or water from the outside.

6、拆下?lián)u臂室蓋，觀(guān)察是否有進(jìn)水。檢查發(fā)電機繞組絕緣/污染情況。

Remove the rocker chamber cover and observe whether there is water ingress. Check the insulation and ontamination of the generator windings.

7、檢測控制線(xiàn)路和輸出電路的絕緣。檢測控制面板模塊、各儀表、告警裝置、啟動(dòng)開(kāi)關(guān)。

Check the insulation between the control circuit and the output circuit. Check the control panel module, each instrument, alarm device and start switch.

注意：絕對不能讓水侵入發(fā)動(dòng)機的燃燒室！

Note: Never let water enter the combustion chamber of the engine!

    柴油發(fā)電機組進(jìn)水后的處理辦法：

Treatment  after water enter the generator:

當判斷柴油發(fā)電機組發(fā)動(dòng)機的燃燒室沒(méi)有進(jìn)水，絕緣符合要求時(shí)，可啟動(dòng)柴油發(fā)電機組。在啟動(dòng)時(shí)要注意以下問(wèn)題：

When confirm there is no water in the combustion chamber  and the insulation meets the requirements,can start the generator. Pay attention to the following issues when starting:

1、在啟動(dòng)前進(jìn)行所有檢查，包括排放燃油箱積水。電氣系統逐步上電，觀(guān)察是否有異常。

Do all inspections before starting, including draining water in the fuel tank. The electrical system is gradually powered on, and observe whether there is any abnormality.

2、連續啟動(dòng)發(fā)動(dòng)機的時(shí)間不得超過(guò)30秒鐘。若發(fā)動(dòng)機不能著(zhù)火，則檢查燃油管路及電氣回路，一兩分鐘后再次啟動(dòng)。

Start the engine continuously shall not exceed 30 seconds. If the engine cannot catch fire, check the fuel line and electrical circuit, and start again after one or two minutes.

3、檢查發(fā)動(dòng)機聲音是否有異常，是否有異味。檢查電氣儀表的顯示、液晶顯示屏是否斷屏或者顯示不清。

Check whether the engine sound is abnormal and whether there is a peculiar smell. Check whether the display of the electrical instrument and the LCD screen are broken or unclear.

4、密切觀(guān)察機油壓力和水溫度，如果油壓或溫度不符合技術(shù)規范，應關(guān)閉發(fā)動(dòng)機。停機后，檢查一次機油平面。

Closely observe the oil pressure and water temperature. If the oil pressure or temperature does not meet the technical specifications, the engine should be shut down. After stopping, check the oil level.

 當判斷發(fā)動(dòng)機可能進(jìn)水、發(fā)電機絕緣不符合要求時(shí)，切勿擅自維修，應尋求發(fā)電機組廠(chǎng)家的專(zhuān)業(yè)技術(shù)人員的幫助。

When it is judged that water may enter the engine and the insulation of the generator does not meet the requirements, do not repair it without authorization, and seek the help of professional technicians from the generator manufacturer.
