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發電機懸置斷裂。

① Broken generator mount.

②發電機懸置固定螺栓鬆動。

② The fixing bolts of the generator mount are loose.

③發電機懸置緩衝墊塊失效或脫落。

③ The generator suspension cushion block fails or falls off.

④發電機懸置位置不當，使傳動部分不同軸心。

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

⑵80千瓦燃氣發電機診斷與處理方法

⑵ diagnosis and treatment methods of 80 kW gas generator

①診斷發電機的抖動可結合聲響來判斷。對於原地起動的發電機，如果沒有明顯的異響而抖動，說明是支承不牢固引起的，應仔細檢查懸置是否斷裂，固定螺栓是否鬆動，緩衝墊塊是否損壞或脫落，並及時修理。

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如果原地起動發電機並沒有抖動，而架起驅動橋掛擋運轉後產生抖動，則說明是傳動部分同軸度偏差過大，應檢查懸置是否移位。檢查的方法是：在架起驅動橋的同時，擰鬆發電機固定螺栓，起動發電機運轉，觀察發電機懸置有無擺動現象，若有擺動，則肯定是傳動部分同軸度偏差過大，應予調整。

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如果發電機原地起動後有異響，且排氣煙色不正，則應按噴油不正時、各缸供油不均和個別缸不工作進行排除。

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對於使用已久的或在惡劣環境下工作的發電機，若異響較明顯，應視各機件的鬆曠程度，予以檢修處理。

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對於剛維修不久的車輛，則應考慮是否屬動平衡失效而造成的車輛抖動。

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.
