識(shí)別發(fā)電機(jī)組新舊方法你知道嗎?

發(fā)布時(shí)間:2023-04-15 發(fā)布人:中拓 發(fā)布來(lái)源:http://www.ptvydps.cn/
一問(wèn):就是詢問(wèn)柴油機(jī)的購(gòu)置時(shí)間、用途及出售原因,修理情況和更換過(guò)哪些主要零部件,使用中有些什么問(wèn)題等,以對(duì)該機(jī)有個(gè)比較全面的解。
One question: It is to inquire about the purchase time, purpose, and reason for sale of the diesel engine, the repair status, which main components have been replaced, and any problems encountered during use, in order to have a comprehensive understanding of the engine.
二看:就是看該機(jī)型是否屬淘汰機(jī)型,再?gòu)耐獗砜床裼蜋C(jī)的新舊程度,后檢查零部件是否齊全,有無(wú)損壞。
Secondly, it is to first check whether the model is an outdated model, then to see the degree of novelty of the diesel engine from its appearance, and finally to check whether the components are complete and undamaged.
三試:就是試機(jī),柴油發(fā)電機(jī)組的具體方法是
Three tests: test the engine. The specific method of diesel generator set is
搖轉(zhuǎn)曲軸,使噴油泵供油,如噴油嘴發(fā)出清脆的噴油聲,說(shuō)明柱塞副和噴油嘴性能尚好;如齒輪室內(nèi)無(wú)異常聲響,說(shuō)明齒輪的磨損不嚴(yán)重。
Shake the crankshaft to supply oil to the fuel injection pump. If the fuel injection nozzle emits a crisp sound, it indicates that the performance of the plunger pair and fuel injection nozzle is still good; If there is no abnormal sound inside the gear compartment, it indicates that the wear of the gear is not severe.
工業(yè)尾氣發(fā)電機(jī)組
上下晃動(dòng)飛輪,如無(wú)響聲、無(wú)明顯晃動(dòng),說(shuō)明曲軸主軸頸與軸瓦的間隙不大;轉(zhuǎn)動(dòng)飛輪,如無(wú)嗒嗒聲,說(shuō)明曲軸連桿軸頸與連桿瓦之間的磨損不嚴(yán)重。
Shake the flywheel up and down, if there is no sound or obvious shaking, it indicates that the clearance between the crankshaft main journal and the bearing shell is not large; If there is no clicking sound when rotating the flywheel, it indicates that the wear between the crankshaft connecting rod journal and connecting rod bearing is not severe.
使氣缸減壓,搖轉(zhuǎn)曲軸,當(dāng)拆除減壓時(shí),如活塞的反彈力大,飛輪迅速回轉(zhuǎn),說(shuō)明氣缸套、活塞、活塞環(huán)的磨損水平小。這時(shí)機(jī)油壓力表讀數(shù)應(yīng)不低于1或機(jī)油壓力指示紅色浮標(biāo)能很快升起,手壓浮標(biāo)應(yīng)費(fèi)力。
Depressurize the cylinder and rotate the crankshaft. When decompressing, if the rebound force of the piston is large, the flywheel rotates rapidly, indicating that the wear level of the cylinder liner, piston and piston ring is small. At this point, the reading of the oil pressure gauge should not be less than 1 or the red float indicating oil pressure can quickly rise, and manual pressure on the float should be laborious.
起動(dòng)柴油機(jī)比較容易,排氣無(wú)色或淺灰色,轉(zhuǎn)速穩(wěn)定,無(wú)雜音,則說(shuō)明柴油機(jī)技術(shù)狀態(tài)良好。
Starting a diesel engine is relatively easy, with colorless or light gray exhaust, stable speed, and no noise, indicating that the diesel engine is in good technical condition.
