有部分企业购买柴油发电机组是作为备用电源使用的，如果市电供电正常，柴油发电机组基本不需要运行，为防止备用柴油发电机组因长期搁置导致故障，应加强日常维修保养，因为只有这样避免使用时出现故障，这是科学经济有效的方法。

Some generators are for backup power source. If the mains power supply is normal, generators will not be operated. In order to prevent backup generators from malfunctioning due to long-term shelving, please keep daily maintenance,this way can avoid failure during working,and It is economical and effective.

柴油发电机组冷却系统有故障会导致：1、柴油发电机组冷却效果差，机组内水温过高，导致停机；2、会导致柴油发电机组水箱漏水，水箱内水位下降，机组无法正常工作。

Generator cooling system failure will cause the cooling effect to be poor, and the water temperature too high, resulting in generator shutdown.And It will cause the radiator to leak, the water level will drop, and the generator will not work normally.

柴油发电机组冷却液不循环的原因有以下几个方面：

3、柴油发电机组水泵故障。检查水泵作用是否良好，如果发现水泵传动齿轴磨损过限时说明水泵已起不到作用，需要更换后才能循环正常。

The water pump failure. Check whether the water pump works well. If it is found that the gear shaft of the water pump is worn out, it means that the water pump has no effect, and it needs to be replaced before the circulation can be normal.

4、柴油发电机组节温器故障。发动机燃烧室内装有节温器，目的在于控制发动机燃烧室温度，节温器必须在规定温度（82度）完全打开有助于小循环，如果没有节温器，冷却液不能保持循环温度，可能会产生低温报警。

The thermosta faulty.The engine combustion chamber is equipped with the thermocontroller to control the engine combustion chamber temperature, which must be fully opened at the specified temperature (82 degrees). Without the thermostat, the coolant cannot maintain the circulating temperature and may produce a low temperature alarm.

5、柴油发电机组冷却系统中混有空气，造成管路不畅通，膨胀水箱上吸气阀、排气阀损坏也直接影响循环，这时应经常检查它们的压力值是否符合规定，吸气压力是10kpa，排气压力是40kpa，除次之外排气管路是否畅通也是影响循环的重要原因。

Air is mixed in the cooling system,causing the pipeline to be blocked.Damage to the suction and exhaust valves on the expansion tank also directly affects the circulation. At this time,should always check whether their pressure values meet the regulations.The suction pressure is 10kpa,The exhaust pressure is 40kpa,In addition, whether the exhaust pipe is unblocked is also an important reason for affecting the circulation.
