    山东装载机发动机拉缸是什么原因?

    山东装载机http://www.sdyongbaojixie.com/发动机拉缸是指活塞与汽缸相互运动造成严重表面损伤,损伤原因大多是由于运动部位的润滑油膜受到局部破坏或有异物杂屑摩擦而造成的,下面永保机械的有关专家就给大家详细分析一下。
      
    1、山东装载机活塞与气缸配合间隙过小,导致磨损加剧,杂物进入后,造成的磨损伤害也加大,油路系统出现问题或机油选用不当,导致活塞与气缸之间润滑不良,无法给活塞及气缸提供足够的油膜的保护,造成磨损、划伤。
    Shandong loaders piston and cylinder gap is too small, leading to increased wear, after the debris into the cause of the wear and tear injuries also increased, oil system problems arise or improper oil selection, leading to poor lubrication between the piston and the cylinder, the piston can not give and provide adequate oil film to protect the cylinder, causing wear and tear, scratches.
      
    2、山东装载机发动机大修后,没有磨合好就长时间高速或超负荷运转,部件磨合不完全,磨损加大,磨损产生的碎屑还会对气缸和活塞造成二次伤害。
    After Shandong loader engine overhaul, no good on a long run-in high-speed or overload, components run-incomplete, increased wear, wear debris generated by the cylinder and piston will cause secondary damage.
      
    4、山东装载机http://www.sdyongbaojixie.com/空气滤清系统出现问题,空气杂质混入燃烧室后附着在汽缸壁上,杂质在燃烧中碳化,变成颗粒,伤害气缸和活塞,长期超载低速运行,加大对活塞和气缸的磨损。
    Shandong loader air filtration system problems, air impurities mixed chamber attached to the cylinder wall, the impurities in the combustion carbonization into granules, cylinder and piston damage, long-term overload low speed, increase the piston and cylinder wear .
