當雨季或臺風季來臨時，有可能遭受洪水、暴雨等自然災害的影響，因柴油發電機組機房一般是在地下室或者1樓容易被水淹，如果發電機組保管防護不善或者其他原因水有可能從煙管進入發動機缸體。當柴油發電機組進水時，如在運轉請立即停機，并采取必要的措施，斷開外電源及蓄電池接駁線，同時檢查各個部位的進水情況。

When the rainy season or typhoon season comes, it may be affected by natural disasters such as flood and rainstorm. Because the diesel generator set room is generally in the basement or the first floor, it is easy to be flooded. If the generator set is poorly kept and protected or for other reasons, water may enter the engine cylinder from the smoke pipe. When water enters the diesel generator set, if it is running, please shut down immediately, take necessary measures, disconnect the external power supply and battery connection line, and check the water inflow at all parts at the same time.

檢查柴油發電機組進水常見問題

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、風扇、聯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、拆下搖臂室蓋，觀察是否有進水。檢查發電機繞組絕緣/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、啟動開關。

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動機的燃燒室！

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

進水處理方法

柴油發電機組進水后的處理辦法：

Treatment  after water enter the generator:

當判斷柴油發電機組發動機的燃燒室沒有進水，絕緣符合要求時，可啟動柴油發電機組。在啟動時要注意以下問題：

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、在啟動前進行所有檢查，包括排放燃油箱積水。電氣系統逐步上電，觀察是否有異常。

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、連續啟動發動機的時間不得超過30秒鐘。若發動機不能著火，則檢查燃油管路及電氣回路，一兩分鐘后再次啟動。

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、檢查發動機聲音是否有異常，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、密切觀察機油壓力和水溫度，如果油壓或溫度不符合技術規范，應關閉發動機。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.

當判斷發動機可能進水、發電機絕緣不符合要求時，切勿擅自維修，應尋求發電機組廠家的專業技術人員的幫助。

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.

暴雨/潮濕環境，柴油發電機組使用注意要點

Key points for unit operation in rainstorm / humid environment

1、放置環境要求1. Placement environment requirements

（1）戶外放置使用的機組，需做好防雨措施，配置防雨棚、靜音箱等；

Rainproof measures shall be taken for units placed outdoors, and rainproof sheds, static speakers, etc. shall be equipped;

（2）機組外殼須有可靠的保護接地，對需要有中性點直接接地的發電機,則必須由專業人員進行中性接地；

The shell of the unit must be reliably grounded. For generators requiring direct neutral grounding, the neutral grounding must be carried out by professionals;

（3）雷電多發地區使用機器，請配置防雷裝置。

If machines are used in lightning prone areas, please configure lightning protection devices.

（4）請不要將機組放置于地勢較低，地基不牢（泥土地面）容易積水的地方；

Please do not place the unit in a place with low terrain, weak foundation (soil ground) and easy to accumulate water;

（5）放置在地下室使用的機器，需做好地下室排水、防潮工作。

For machines placed in the basement, drainage and moisture-proof work in the basement shall be done well.
