發電機組被雨淋之后需注重保養方法，這是很關鍵的一個事情，如不及時修護，將會造成發電機組銹蝕、腐蝕，出現損壞。下面來簡單了解一番吧。

Maintenance methods should be paid attention to after the generator set is rained, which is a key thing. If it is not repaired in time, the generator set will be rusted, corroded and damaged. Let's have a brief look.

用水沖洗發電機外部，去除泥土和雜物，然后用金屬清潔劑或洗衣粉去除表面的油漬。

Wash the outside of the generator with water to remove dirt and sundries, and then use metal cleaner or washing powder to remove oil stains on the surface.

支撐發電機一端，使油底殼放油部分處于低位，擰下放油螺塞，拉出油尺，讓油底殼內的水自行流出。稍微讓油和水一起排出，然后擰上放油塞。

Support one end of the generator so that the oil drain part of the oil pan is in the low position, screw the oil drain plug, pull out the dipstick, and let the water in the oil pan flow out by itself. Allow the oil and water to drain slightly, then screw on the oil drain plug.

拆下發電機組空氣濾清器，拆下濾清器上殼，取出濾芯等部件，除去濾清器內的水分，用金屬清洗劑或柴油清洗零件。如果過濾器是塑料泡沫制成的，應先用洗衣粉或肥皂水（無汽油）清洗，然后用清水沖洗干凈，晾干，然后用適量機油浸泡（浸泡后用盡量用手）。更換新濾清器時應進行同樣的油浸處理。濾芯是紙質的，需要更換新的。過濾器各部件清洗干燥后，按規定安裝。

Remove the air filter of the generator set, remove the upper shell of the filter, take out the filter element and other components, remove the water in the filter, and clean the parts with metal cleaner or diesel oil. If the filter is made of plastic foam, it should be cleaned with washing powder or soapy water (without gasoline), then washed with clean water, dried, and soaked with an appropriate amount of engine oil (after soaking, use your hands as much as possible). Replace the new filter with the same oil immersion treatment. The filter element is paper and needs to be replaced. After the filter components are cleaned and dried, they shall be installed as required.

拆下進、排氣管和消音器，排除內部積水。開啟減壓，搖動發電機，看進、排氣口是否有水排出。如果有水排出，繼續搖動曲軸，直到氣缸內的水全部排出。安裝進排氣管和消音器，在進氣口加少許油，曲軸轉動幾次，然后安裝空氣濾清器。如果由于發電機進水時間長而使飛輪轉動困難，則說明缸套和活塞環已經生銹。應將它們拆下以去除銹跡，清潔后再組裝。如果銹蝕嚴重，應及時更換。

Remove the intake and exhaust pipes and silencer to drain the internal water. Turn on the pressure reducer, shake the generator, and check whether there is water discharged from the inlet and outlet. If water is drained, continue to shake the crankshaft until all the water in the cylinder is drained. Install the air inlet and exhaust pipe and silencer, add a little oil to the air inlet, turn the crankshaft several times, and then install the air filter. If it is difficult for the flywheel to rotate due to the long water inflow time of the generator, it indicates that the cylinder liner and piston ring have been rusted. They should be removed to remove rust and cleaned before assembly. If the corrosion is serious, replace it in time.

拆下油箱，將油箱內的油水全部排出。檢查濾清器和油管內是否有水，如果有水，應將其放掉。清潔油箱和柴油濾清器，然后將它們放回原位，連接燃油回路，將清潔的柴油加入油箱。

Remove the oil tank and drain all the oil and water in the tank. Check whether there is water in the diesel filter and oil pipe. If there is water, drain it. Clean the fuel tank and diesel filter, then put them back in place, connect the fuel circuit, and add clean diesel to the fuel tank.

放掉水箱和水路中的污水，清洗水路，加入干凈的河水或煮沸的井水，直到水浮起。打開油門開關并啟動發電機。瓦斯發電機組啟動后，注意觀察油位指示器的上升情況，聽發電機是否有異響。檢查所有部件是否正常后，在發電機中運行。磨合順序為先怠速、后中速、后高速，每次運行時間為5min。磨合后，停機放油。重新添加新油，啟動發電機，中速運轉5分鐘，即可正常使用。

Drain the sewage from the water tank and waterway, clean the waterway, and add clean river water or boiled well water until the water floats. Open the throttle switch and start the generator. After the generator of the gas generator set is started, pay attention to the rise of the oil level indicator and listen to whether the generator has abnormal noise. After checking whether all components are normal, operate in the generator. The running in sequence is idling first, then medium speed, and then high speed, and each running time is 5min. After running in, stop the machine and drain the oil. Add new oil again, start the generator and run it at medium speed for 5 minutes, and then it can be used normally.

采取以上措施，可有效使發電機組恢復到良好狀態，消除后期運行的安全隱患。當然要提醒大家，如果發電機組必須在室外使用，請隨時封鎖工作，以防突發天氣造成不必要的損失。

Taking the above measures can effectively restore the generator set to a good state and eliminate the potential safety hazards in later operation. Of course, we should remind you that if the generator set must be used outdoors, please block the work at any time to prevent unnecessary losses caused by sudden weather.
