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(fā)電機(jī)懸置斷裂。

① Broken generator mount.

②發(fā)電機(jī)懸置固定螺栓松動(dòng)。

② The fixing bolts of the generator mount are loose.

③發(fā)電機(jī)懸置緩沖墊塊失效或脫落。

③ The generator suspension cushion block fails or falls off.

④發(fā)電機(jī)懸置位置不當(dāng)，使傳動(dòng)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?xì)獍l(fā)電機(jī)診斷與處理方法

⑵ diagnosis and treatment methods of 80 kW gas generator

①診斷發(fā)電機(jī)的抖動(dòng)可結(jié)合聲響來(lái)判斷。對(duì)于原地起動(dòng)的發(fā)電機(jī)，如果沒(méi)有明顯的異響而抖動(dòng)，說(shuō)明是支承不牢固引起的，應(yīng)仔細(xì)檢查懸置是否斷裂，固定螺栓是否松動(dòng)，緩沖墊塊是否損壞或脫落，并及時(shí)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(dòng)發(fā)電機(jī)并沒(méi)有抖動(dòng)，而架起驅(qū)動(dòng)橋掛擋運(yùn)轉(zhuǎn)后產(chǎn)生抖動(dòng)，則說(shuō)明是傳動(dòng)部分同軸度偏差過(guò)大，應(yīng)檢查懸置是否移位。檢查的方法是：在架起驅(qū)動(dòng)橋的同時(shí)，擰松發(fā)電機(jī)固定螺栓，起動(dòng)發(fā)電機(jī)運(yùn)轉(zhuǎn)，觀察發(fā)電機(jī)懸置有無(wú)擺動(dòng)現(xiàn)象，若有擺動(dòng)，則肯定是傳動(dòng)部分同軸度偏差過(guò)大，應(yīng)予調(diào)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(fā)電機(jī)原地起動(dòng)后有異響，且排氣煙色不正，則應(yīng)按噴油不正時(shí)、各缸供油不均和個(gè)別缸不工作進(jìn)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(duì)于使用已久的或在惡劣環(huán)境下工作的發(fā)電機(jī)，若異響較明顯，應(yīng)視各機(jī)件的松曠程度，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(duì)于剛維修不久的車輛，則應(yīng)考慮是否屬動(dòng)平衡失效而造成的車輛抖動(dòng)。

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.
