Strengthening routine maintenance is an effective way to prolong the service life of the generator. The generator set manufacturer reminds you that if the generator set is in a static state, various materials of the unit itself will have complex chemical and physical changes with engine oil, cooling water, diesel oil, air, etc., so as to "stop" 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)。

The water pump, water tank and water transmission pipeline are not cleaned for a long time, resulting in poor water circulation, reduced cooling effect, good water pipe joints, water tank and water channel leakage, etc. if the cooling system fails, the consequences are: the water temperature in the unit is too high due to poor cooling effect, and the Wilson unit is the most common; If the water level in the water tank drops due to water leakage in the water tank, the unit will not work normally (in order to prevent the water pipe from freezing when the generator is used 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 output of engine power is mainly the work done by the fuel burning in the cylinder, and the fuel is sprayed through the fuel injection nozzle, which makes the carbon deposit after combustion deposited in the fuel injection nozzle. With the increase of deposition, the fuel injection quantity of the fuel injection nozzle will be affected to a certain extent, resulting in inaccurate ignition advance angle time of the fuel injection nozzle, uneven fuel injection quantity of each cylinder of the engine and unstable working state, Therefore, the fuel system shall be cleaned regularly, the filter components shall be replaced, the fuel supply shall be unblocked, and the gas distribution system shall be adjusted to make its ignition uniform.

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 is used to filter diesel oil, engine oil or water to prevent impurities from entering the engine body, and oil and impurities in diesel oil are also inevitable. Therefore, during the operation of the unit, the filter plays an important role, but at the same time, these oil or impurities are deposited on the filter screen wall, which reduces the filtering capacity of the filter. If they are deposited too much, the oil circuit will not be unblocked, In this way, when the oil engine runs with load, it will be shocked due to lack of oil supply (such as lack of oxygen in the same person). Therefore, during the use of normal generator units, we suggest that the three filters of common units be replaced every 500 hours; Replace the three filters of the standby unit every two years;
