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.

三种发电机组坏掉的修理方法：

Three repair methods for damaged generator sets:

1、发电机组无法开启

1. The generator set cannot be started

发电机组的成功开启肯定是要有足够快的转速，好的气缸压缩力以及喷进雾化良好的燃油而且还要有一定的温度，让雾化的燃油达到着火的情况。

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.

无开启的时候，应该先去检查电路的问题，按下开启的按钮，起动马达无动作就代表电路断路或者是接触不良，如果只有启动齿轮与飞轮齿圈撞击声就是大、小齿轮无法啮合，这个时候只要把飞轮盘动一至数齿就行，若起动马达转而无力、转速低就代表是电瓶电力不够。

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、发电机组功率不够

2. Insufficient power of the generator set

基本上就是机组低速运转不平稳，高速时排气管冒黑烟会发出异响，发电机组在没有达到大修的情况下，功率不够一般都是燃油供给系统出现问题和气缸压缩力不够导致的。

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.

这个时候就先空车检查，如果加大油门，空车可以达到高转速就是故障在工作机械，如果空车转速上不去就代表故障在发电机组。

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.

检查排气歧管根部的温度，如果温度过低就是这个缸不工作或者是工作不良，低速时可用手指触摸检查，高速的时候就不要这样做了，免得烫伤手指，这个时候就可以向排气歧管的根部吐唾液，如果唾液没有发出那种被高温蒸发的声音就代表这个缸坏掉了。

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、自动熄火

3. Automatic flameout

自动熄火的原因太多了，但是常见的基本就是燃油供给中断和运动件受阻这两个问题。

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

在正常运转的时候，如果，转速慢慢的掉下来，声音慢慢的变小，油温、压力、水温都正常，推动油门没有效果，延续一段时间后再慢慢的熄火，停车后用改锥能盘动飞轮就代表是燃油供给不畅或中断。

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.

在运转过程中，水温正常，机油压力下降，油温上升，油里面有金属的碎片，有机油烧干的气味，机器振动变快，声音异常，转速慢慢的降低，停车时惯性转动时间短，停车后盘不动飞轮，机器降温后还是盘不动飞轮那就可以确定是主轴烧瓦。

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.
