　　在工业生产中，工业尾气发电机就像一位默默工作的 “能量转换大师”，将废弃尾气转化为电能。但当它突然 “罢工” 无法启动时，会打乱整个生产节奏。想要让它重新 “苏醒”，就得化身 “侦探”，抽丝剥茧找出故障原因。

　　In industrial production, industrial exhaust gas generators are like a silent "energy conversion master", converting waste exhaust gas into electrical energy. But when it suddenly goes on strike and cannot start, it will disrupt the entire production rhythm. To revive it, one must transform into a "detective" and unravel the root cause of the malfunction.

　　燃料供应问题是导致工业尾气发电机无法启动的常见 “元凶”。尾气作为发电机的 “燃料”，若供应不足或质量不达标，发电机将难以启动。比如，尾气输送管道出现堵塞，内部残留的杂质、凝结物阻碍尾气正常流动，导致进入发电机的尾气量过少，无法满足启动需求。管道阀门故障同样会影响尾气供应，阀门未完全打开、阀芯卡死或密封不严，都会使尾气无法顺畅输送。此外，尾气的成分和浓度对发电机启动也至关重要。若尾气中可燃成分比例过低，或混入过多不可燃气体，热值达不到启动标准，发电机也会拒绝 “工作” 。

　　Fuel supply issues are a common "culprit" that causes industrial exhaust generators to fail to start. Exhaust gas, as the "fuel" for generators, will be difficult to start if the supply is insufficient or the quality does not meet the standards. For example, if the exhaust gas delivery pipeline is blocked, residual impurities and condensates inside will hinder the normal flow of exhaust gas, resulting in insufficient exhaust gas entering the generator and unable to meet the start-up requirements. Malfunctions in pipeline valves can also affect the supply of exhaust gas. Valves that are not fully opened, valve cores that are stuck, or seals that are not tight can all prevent the smooth delivery of exhaust gas. In addition, the composition and concentration of exhaust gas are also crucial for generator start-up. If the proportion of combustible components in the exhaust is too low or too much non combustible gas is mixed in, and the calorific value does not meet the starting standard, the generator will also refuse to "work".

　　电气系统故障犹如发电机的 “神经系统紊乱”，严重影响其启动。发电机的启动依赖于复杂的电气线路和设备协同工作。电源故障可能是源头问题，如外部供电线路停电、电压不稳定，或者发电机自身的蓄电池电量不足、老化损坏，无法为启动电机提供足够电力。启动电机故障也不容忽视，若启动电机内部绕组短路、断路，或碳刷磨损严重，无法产生足够的转矩带动发电机运转，就会导致启动失败。此外，控制电路出现问题，如继电器损坏、控制模块故障，无法正确传输启动信号，使发电机接收到错误指令或根本接收不到指令，自然也无法正常启动。

　　Electrical system failures are like the 'nervous system disorder' of a generator, seriously affecting its start-up. The start-up of a generator relies on complex electrical circuits and equipment working in coordination. Power failure may be the root cause, such as power outages or unstable voltage in external power supply lines, or insufficient or aging damage to the generator's own battery, which cannot provide sufficient power to the starter motor. The fault of the starter motor cannot be ignored. If the internal winding of the starter motor is short circuited or disconnected, or if the carbon brush is severely worn and unable to generate sufficient torque to drive the generator to operate, it will lead to starting failure. In addition, if there are problems with the control circuit, such as relay damage or control module failure, the generator cannot transmit the start signal correctly, resulting in receiving incorrect instructions or not receiving instructions at all, and naturally unable to start normally.

　　机械部件的异常状况是阻碍发电机启动的另一大因素。发动机内部的活塞、曲轴、连杆等关键部件，若出现磨损、卡死等情况，会直接影响发动机的正常运转。长期使用后，活塞环磨损严重，导致气缸密封性下降，压缩比不足，无法达到燃油燃烧所需的条件，进而无法启动。曲轴或连杆因受力不均发生变形，会使发动机运转阻力增大，启动电机难以带动其转动。此外，发电机的传动系统，如皮带、链条等，若出现松动、断裂，无法将动力有效传递，也会导致发电机无法启动。

　　The abnormal condition of mechanical components is another major factor hindering the start of the generator. If key components such as pistons, crankshafts, connecting rods, etc. inside the engine are worn or stuck, it will directly affect the normal operation of the engine. After long-term use, the piston rings wear severely, resulting in a decrease in cylinder sealing and insufficient compression ratio, which cannot meet the conditions required for fuel combustion and thus cannot start. The deformation of the crankshaft or connecting rod due to uneven force can increase the resistance to engine operation, making it difficult for the starter motor to drive its rotation. In addition, if the transmission system of the generator, such as belts, chains, etc., becomes loose or broken, it cannot effectively transmit power and can also cause the generator to fail to start.

　　冷却与润滑系统故障虽不直接影响启动，但长期异常会使发电机内部温度过高、摩擦增大，最终导致无法启动。冷却系统若存在冷却液泄漏、散热器堵塞、水泵故障等问题，会使发动机在运转前就处于高温状态，各部件因热膨胀出现配合间隙变化，增加启动阻力，甚至可能因高温损坏部件。润滑系统同样关键，机油量不足、机油变质、机油泵故障等，会使发动机内部部件得不到良好润滑，摩擦加剧，产生大量热量和磨损，久而久之，导致发动机无法正常启动。

　　Although the failure of the cooling and lubrication system does not directly affect the start-up, long-term abnormalities can cause the internal temperature of the generator to become too high and friction to increase, ultimately leading to the inability to start. If the cooling system has problems such as coolant leakage, radiator blockage, water pump failure, etc., it will cause the engine to be in a high temperature state before operation, resulting in changes in the fitting clearance of various components due to thermal expansion, increasing starting resistance, and even possibly damaging components due to high temperature. The lubrication system is equally critical. Insufficient oil volume, oil deterioration, and oil pump failure can cause poor lubrication of internal components of the engine, increase friction, generate a large amount of heat and wear, and over time, lead to the engine being unable to start normally.
