在内燃机、拖拉机以及其它农业机械的使用过程中,有时会遇到这种情况:某个零件忽然异乎寻常地发生损坏,换用了新品后不久又同样损坏,并且接二连三地损坏。为尽量减少或杜绝这种情况的发生,下面谈谈零件连续损坏的原因以及防止的注意事项,供大家参考。零件连续损坏的原因除了某批零件的质量不合格以外,造成零件连续损坏的原因通常有以下几点: 一、在检修中更换了某零件(新品或修复品),而该零件的某一部位不合技术要求,安装时又没有发现,从而引起其它有关零件的连续损坏。例如,某团场有一台东方红—54推土机,在一次修理时更换了新的后桥壳,修出后试运转不到两小时,动力输出轴就折断了。换上一根新轴,一个多小
In the use of internal combustion engines, tractors and other farm machinery, there are times when a part suddenly and unexpectedly breaks down, becomes damaged shortly after it is replaced with new one, and is damaged one after another. To minimize or eliminate the occurrence of this situation, the following talk about the reasons for continuous damage to the parts and prevent precautions for your reference. The reasons for the continuous damage to parts Except for the quality of some parts which are not qualified, the reasons for the continuous damage to the parts are as follows: First, a part (new or repaired) is replaced during maintenance, and a part of the part Not meet the technical requirements, installation and did not find, causing other continuous damage to the parts. For example, a group field Dongfanghong-54 bulldozers, a repair time to replace the new rear axle housing, repair after the trial run less than two hours, the PTO shaft broken. Put on a new shaft, a little more
