柴油发电机组在日常使用中确实会有故障存在，而故障的类型也有很多，当对于客户来说，并不了解故障类型，往往不清楚这些故障，为此山东祥捷动力准备给大家简单介绍下常见的几个故障。

Diesel generator sets do indeed have faults in daily use, and there are many types of faults. When customers are not familiar with the types of faults, they often do not understand these faults. Therefore, Shandong Xiangjie Power is ready to briefly introduce several common faults to everyone.

机械故障：

Mechanical failure:

轴承问题：轴承磨损、润滑不良等，可能导致发电机组运行不稳定，甚至停机。

Bearing problems: Bearing wear, poor lubrication, etc. may cause unstable operation of the generator set, and even shutdown.

冷却系统故障：水道堵塞、散热器故障等，可能导致发电机组过热。

Cooling system malfunction: blockage of water channels, radiator failure, etc., may cause overheating of the generator set.

振动和噪音：由于机械部件松动、不平衡或损坏，可能产生异常的震动和噪音。

Vibration and noise: Abnormal vibration and noise may occur due to loose, unbalanced, or damaged mechanical components.

电气故障：

Electrical fault:

发电机励磁系统故障：如主励磁故障，可能导致发电机没有励磁电流或励磁电流过大。

Generator excitation system failure: If the main excitation fails, it may cause the generator to have no excitation current or excessive excitation current.

发电机绝缘故障：绝缘老化和损坏、绝缘击穿等，可能导致电气性能下降，甚至引发短路。

Generator insulation failure: insulation aging and damage, insulation breakdown, etc., may lead to a decrease in electrical performance, and even cause short circuits.

电气接触不良：接线端子松动或腐蚀，可能导致电流传输不畅，引发电气火花或加热。

Poor electrical contact: Loose or corroded wiring terminals may cause poor current transmission, leading to electrical sparks or heating.

燃油系统故障：

Fuel system malfunction:

供油不畅：燃油泵故障、燃油滤清器堵塞等，可能导致发电机功率不足或停机。

Poor fuel supply: Fuel pump failure, fuel filter blockage, etc. may cause insufficient power or shutdown of the generator.

燃油质量问题：如燃油含水量超标、燃油质量差，可能导致发电机冒白烟、功率下降等。

Fuel quality issues: such as excessive water content and poor fuel quality, may lead to white smoke and reduced power from the generator.

控制系统故障：

Control system malfunction:

控制模块故障：如调速器、电压调节器等损坏或失调，可能影响发电机的输出稳定性。

Control module malfunction: Damage or misalignment of speed controllers, voltage regulators, etc. may affect the output stability of the generator.

传感器故障：如温度传感器、压力传感器等失效，可能导致控制系统误判或失效。

Sensor failure: Failure of temperature sensors, pressure sensors, etc. may lead to misjudgment or failure of the control system.

其他故障：

Other faults:

发电机组漏油：由于密封件老化或损坏，可能导致润滑油或燃油泄漏。

Generator unit oil leakage: Due to aging or damage to the sealing components, it may cause lubricating oil or fuel leakage.

启动困难：电池电压过低、启动回路故障等，可能导致发电机组无法启动。

Difficulty starting: Low battery voltage, starting circuit failure, etc. may cause the generator set to fail to start.
