The vibration of 80 kW gas generator in operation is mainly caused by improper support, except for the factors such as improper fuel injection timing of power generation machinery, abnormal operation of each cylinder and loose wear of various parts.

⑴原因

(1) reasons

①发电机悬置断裂。

① Broken generator mount.

②发电机悬置固定螺栓松动。

② The fixing bolts of the generator mount are loose.

③发电机悬置缓冲垫块失效或脱落。

③ The generator suspension cushion block fails or falls off.

④发电机悬置位置不当，使传动部分不同轴心。

④ The improper mounting position of the generator makes the transmission part different from the axis.

⑵80千瓦燃气发电机诊断与处理方法

⑵ diagnosis and treatment methods of 80 kW gas generator

①诊断发电机的抖动可结合声响来判断。对于原地起动的发电机，如果没有明显的异响而抖动，说明是支承不牢固引起的，应仔细检查悬置是否断裂，固定螺栓是否松动，缓冲垫块是否损坏或脱落，并及时修理。

① Diagnosis of generator jitter can be judged in combination with sound. For the generator started in place, if there is no obvious abnormal sound and shaking, it indicates that the support is not firm. Carefully check whether the suspension is broken, whether the fixing bolts are loose, and whether the buffer cushion block is damaged or fallen off, and repair it in time.

②如果原地起动发电机并没有抖动，而架起驱动桥挂挡运转后产生抖动，则说明是传动部分同轴度偏差过大，应检查悬置是否移位。检查的方法是：在架起驱动桥的同时，拧松发电机固定螺栓，起动发电机运转，观察发电机悬置有无摆动现象，若有摆动，则肯定是传动部分同轴度偏差过大，应予调整。

② If the generator does not vibrate when it is started in place, but vibrates after the drive axle is put into gear, it indicates that the coaxiality deviation of the transmission part is too large. Check whether the suspension is displaced. The inspection method is: while erecting the drive axle, loosen the fixing bolts of the generator, start the generator for operation, and observe whether the generator suspension swings. If there is swing, it must be that the coaxiality deviation of the transmission part is too large and should be adjusted.

③如果发电机原地起动后有异响，且排气烟色不正，则应按喷油不正时、各缸供油不均和个别缸不工作进行排除。

③ If there is abnormal noise after the generator is started in place and the exhaust smoke color is not correct, it shall be eliminated according to improper fuel injection timing, uneven fuel supply of each cylinder and non operation of individual cylinders.

④对于使用已久的或在恶劣环境下工作的发电机，若异响较明显，应视各机件的松旷程度，予以检修处理。

④ For generators that have been used for a long time or work in harsh environment, if the abnormal sound is obvious, they shall be overhauled according to the looseness of each machine part.

⑤对于刚维修不久的车辆，则应考虑是否属动平衡失效而造成的车辆抖动。

⑤ For the vehicle that has just been repaired for a short time, consider whether it is the vehicle jitter caused by dynamic balance failure.
