The generator set may not be unfamiliar to everyone, as it is a product that we use as a backup power source during hotel elevator power outages, community power outages, and when there is no power supply but we need to develop wilderness areas. So, has anyone thought about what important things should be done if they break down? Don't worry. Next, the editor will teach you how to repair them.

三種發(fā)電機組壞掉的修理方法：

Three repair methods for damaged generator sets:

1、發(fā)電機組無法開啟

1. The generator set cannot be started

發(fā)電機組的成功開啟肯定是要有足夠快的轉速，好的氣缸壓縮力以及噴進霧化良好的燃油而且還要有一定的溫度，讓霧化的燃油達到著火的情況。

The successful start-up of the generator set must have sufficient speed, good cylinder compression force, and the injection of well atomized fuel, as well as a certain temperature to allow the atomized fuel to reach the point of ignition.

無開啟的時候，應該先去檢查電路的問題，按下開啟的按鈕，起動馬達無動作就代表電路斷路或者是接觸不良，如果只有啟動齒輪與飛輪齒圈撞擊聲就是大、小齒輪無法嚙合，這個時候只要把飛輪盤動一至數(shù)齒就行，若起動馬達轉而無力、轉速低就代表是電瓶電力不夠。

When there is no start, the first thing to do is to check the circuit. Press the start button, and if the starting motor does not move, it means the circuit is open or the contact is poor. If only the starting gear and flywheel gear ring collide, it means that the large and small gears cannot mesh. At this time, just turn the flywheel one to a few teeth, and if the starting motor turns weak or the speed is low, it means that the battery power is insufficient.

2、發(fā)電機組功率不夠

2. Insufficient power of the generator set

基本上就是機組低速運轉不平穩(wěn)，高速時排氣管冒黑煙會發(fā)出異響，發(fā)電機組在沒有達到大修的情況下，功率不夠一般都是燃油供給系統(tǒng)出現(xiàn)問題和氣缸壓縮力不夠導致的。

Basically, the unit operates unevenly at low speeds, and the exhaust pipe emits black smoke and makes abnormal noises at high speeds. Insufficient power of the generator unit before reaching major repairs is generally caused by problems in the fuel supply system and insufficient cylinder compression force.

這個時候就先空車檢查，如果加大油門，空車可以達到高轉速就是故障在工作機械，如果空車轉速上不去就代表故障在發(fā)電機組。

At this point, check the empty car first. If you increase the throttle, the empty car can reach its maximum speed, indicating that the fault is in the working machinery. If the idle car speed does not increase, it indicates that the fault is in the generator set.

檢查排氣歧管根部的溫度，如果溫度過低就是這個缸不工作或者是工作不良，低速時可用手指觸摸檢查，高速的時候就不要這樣做了，免得燙傷手指，這個時候就可以向排氣歧管的根部吐唾液，如果唾液沒有發(fā)出那種被高溫蒸發(fā)的聲音就代表這個缸壞掉了。

Check the temperature at the root of the exhaust manifold. If the temperature is too low, it indicates that the cylinder is not working or is not working properly. At low speeds, you can touch it with your fingers to check. At high speeds, do not do this to avoid burning your fingers. At this point, you can spit saliva at the root of the exhaust manifold. If the saliva does not make the sound of being evaporated by high temperature, it means that the cylinder is broken.

3、自動熄火

3. Automatic flameout

自動熄火的原因太多了，但是常見的基本就是燃油供給中斷和運動件受阻這兩個問題。

There are too many reasons for automatic shutdown, but the common ones are the interruption of fuel supply and the obstruction of moving parts.

在正常運轉的時候，如果，轉速慢慢的掉下來，聲音慢慢的變小，油溫、壓力、水溫都正常，推動油門沒有效果，延續(xù)一段時間后再慢慢的熄火，停車后用改錐能盤動飛輪就代表是燃油供給不暢或中斷。

During normal operation, if the speed slowly drops, the sound gradually decreases, and the oil temperature, pressure, and water temperature are all normal. Pushing on the throttle has no effect. After a period of time, slowly turn off the engine and use a screwdriver to turn the flywheel after parking, it means that the fuel supply is not smooth or interrupted.

在運轉過程中，水溫正常，機油壓力下降，油溫上升，油里面有金屬的碎片，有機油燒干的氣味，機器振動變快，聲音異常，轉速慢慢的降低，停車時慣性轉動時間短，停車后盤不動飛輪，機器降溫后還是盤不動飛輪那就可以確定是主軸燒瓦。

During operation, the water temperature is normal, the engine oil pressure drops, and the oil temperature rises. There are metal fragments in the oil, and there is a smell of engine oil burning dry. The machine vibrates faster, the sound is abnormal, and the speed slowly decreases. When parking, the inertia rotation time is short, and the flywheel cannot be turned after parking. If the machine still cannot be turned after cooling down, it can be determined that the main shaft is burnt.
