80千瓦燃氣發(fā)電機出現抖動(dòng)診斷與處理方法
80千瓦燃氣發(fā)電機在工作中出現抖動(dòng),除去發(fā)電機械噴油不正時(shí)、各缸工作不正常和各部機件磨損松曠等因素外,主要是支承不當引起的。
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)電機懸置斷裂。
① Broken generator mount.
②發(fā)電機懸置固定螺栓松動(dòng)。
② The fixing bolts of the generator mount are loose.
③發(fā)電機懸置緩沖墊塊失效或脫落。
③ The generator suspension cushion block fails or falls off.
④發(fā)電機懸置位置不當,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.
⑵80千瓦燃氣發(fā)電機診斷與處理方法
⑵ diagnosis and treatment methods of 80 kW gas generator
①診斷發(fā)電機的抖動(dòng)可結合聲響來(lái)判斷。對于原地起動(dòng)的發(fā)電機,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,應仔細檢查懸置是否斷裂,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)電機并沒(méi)有抖動(dòng),而架起驅動(dòng)橋掛擋運轉后產(chǎn)生抖動(dòng),則說(shuō)明是傳動(dòng)部分同軸度偏差過(guò)大,應檢查懸置是否移位。檢查的方法是:在架起驅動(dòng)橋的同時(shí),擰松發(fā)電機固定螺栓,起動(dòng)發(fā)電機運轉,觀(guān)察發(fā)電機懸置有無(wú)擺動(dòng)現象,若有擺動(dòng),則肯定是傳動(dòng)部分同軸度偏差過(guò)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(fā)電機原地起動(dòng)后有異響,且排氣煙色不正,則應按噴油不正時(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對于使用已久的或在惡劣環(huán)境下工作的發(fā)電機,若異響較明顯,應視各機件的松曠程度,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對于剛維修不久的車(chē)輛,則應考慮是否屬動(dòng)平衡失效而造成的車(chē)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.
