加强日常维护是延长发电机寿命的有效方法，发电机组厂家提醒你如果机组长斯处于静态，机组本身各种材料会与机油、冷却水、柴油、空气等发生复杂的化学、物理变化，从而将机组“停坏”。

Strengthening daily maintenance is an effective way to extend the lifespan of generators. Generator manufacturers remind you that if the unit is in a static state for a long time, various materials of the unit itself will undergo complex chemical and physical changes with engine oil, cooling water, diesel, air, etc., which will "shut down" the unit.

水泵、水箱及输水管道长时间未作清洗，使水循环不畅，冷却效果下降，水管接头是否良好、水箱、水道是否有漏水等，如果冷却系统有故障，导致的后果有：冷却效果不好而使机组内水温过高而停机，威尔信机组常见;水箱漏水而使水箱内水位下降，机组也会无法正常工作(为防止在冬季使用发电机时，水管冻结，发电机维修建议在冷却系统中安装水加热器)。

If the water pump, water tank, and water delivery pipeline are not cleaned for a long time, resulting in poor water circulation, decreased cooling effect, good water pipe joints, and leakage in the water tank and waterway, etc. If there is a malfunction in the cooling system, the consequences include: poor cooling effect leading to high water temperature inside the unit and shutdown, which is common in Wilson units; If the water tank leaks and the water level inside the tank drops, the unit will also be unable to function properly (to prevent water pipes from freezing when using the generator in winter, it is recommended to install a water heater in the cooling system for generator maintenance).

发动机功率的输出主要是燃油在缸内燃烧做功而燃油是通过喷油嘴喷出，这就使燃烧后的积炭沉积于喷油嘴，随沉积量的增加喷油嘴喷油量将受到一定影响，导致喷油嘴点火提前角时间不准，发动机各缸喷油量也就不均匀，工作状态也就不平稳，所以定期对燃油系统的清洗，过滤部件的更换其供油畅通，对配气系统的调正使其点火均匀。

The main output of engine power is the combustion of fuel in the cylinder to do work, and the fuel is sprayed out through the fuel injector, which causes the carbon deposits after combustion to deposit on the fuel injector. As the deposition amount increases, the injection amount of the fuel injector will be affected to a certain extent, resulting in inaccurate ignition timing of the fuel injector, uneven fuel injection in each cylinder of the engine, and unstable working conditions. Therefore, regular cleaning of the fuel system and replacement of filtering components will ensure smooth fuel supply, Adjust the gas distribution system to ensure even ignition.

滤器是起到对柴油、机油或水过滤作用的，以防杂质进入机体内，而在柴油中油污、杂质也是不可避免的存在，所以在机组运行过程中，过滤器就起到了重要作用，但同时这些油污或杂质也就被沉积在滤网壁上而使滤器过滤能力下降，沉积过多，油路将无法畅通，这样油机带载运行时将会因油无法供给而休克(如同人缺氧)，所以正常发电机组在使用过程中，我们建议：常用机组每500 小时更换三滤;备用机组每二年更换三滤

The filter plays a role in filtering diesel, engine oil, or water to prevent impurities from entering the engine body. Oil and impurities are also inevitable in diesel, so the filter plays an important role during the operation of the unit. However, at the same time, these oil and impurities are also deposited on the filter wall, causing a decrease in the filter's filtering ability. If they deposit too much, the oil circuit will not be smooth, When the oil engine operates under load, it will experience shock due to the inability to supply oil (such as oxygen deficiency). Therefore, during the normal use of the generator set, we recommend that the three filters be replaced every 500 hours for commonly used units; The backup unit should replace the three filters every two years
