全自动发电机机组活塞销有异响处理方式
编辑:广东瓦格耐电力科技有限公司   发布时间:2017-12-12

全自动发电机组在同样转速下,活塞销的响声比活塞敲缸的声音要尖锐清脆连续,且怠速和温度升高后声响混浊不清。可能导致以上状况原因有:
      ① 活塞销与销座孔配合松旷。
      ② 活塞销与连杆衬套磨损,使间隙过大。
      ③ 机油压力过低,机油飞溅不足,润滑不良引起活塞销严重烧蚀。
      ④ 活塞销卡环脱落,使活塞销自由窜动。
      诊断与处理方法:
      全自动发动机由怠速运转升到中速时,抖动油门,声响随之变化,并且每轰一次油门都能听到明显而清脆的连续响声,则可以认为是活塞销响。
      在较高转速下发出的响声比较严重,转速越高响声也越大;在响声最大的转速下进行断油试验,倘若响声不仅未减弱,反而变得杂乱,说明是活塞销与衬套配合松旷。
      当活塞销响声较明显时,必须进行修理,以免打碎活塞,甚至损坏气缸套、缸盖或缸体。

Generator piston ring has abnormal sound handling

Generator at the same speed, the piston pin sound louder than the piston knocking cylinder sound crisp continuous, and the idling and temperature increased after the sound cloudy. Possible reasons for the above conditions are:

(1) the piston pin is loose with the pin hole.

Piston pin and connecting rod bushing wear, so that the gap is too large.

The oil pressure is too low, the oil spatter is not enough, the bad lubrication causes the piston pin to be ablated seriously.

(4) the piston pin ring shedding to make the piston pin move freely.

Diagnosis and treatment methods:

       The engine idling speed rose to medium speed, the dithering throttle, the sound changes, and every time the throttle can hear a clear and crisp continuous sound, you can think of the piston pin.

       The sound emitted at higher speeds is more serious, the higher the speed the louder the louder; at the maximum speed of the ringing off the oil test, if the sound is not only not weakened, but become cluttered, indicating that the piston pin and bushing with loose Kuang.

       When the piston pin noise is more obvious, must be repaired, so as not to break the piston, or even damage cylinder liner, cylinder head or cylinder.
