山東裝載機http://www.sgx498.com/發動機拉缸是指活塞與汽缸相互運動造成嚴重表面損傷，損傷原因大多是由于運動部位的潤滑油膜受到局部破壞或有異物雜屑摩擦而造成的，下面永保機械的有關專家就給大家詳細分析一下。
1、山東裝載機活塞與氣缸配合間隙過小，導致磨損加劇，雜物進入后，造成的磨損傷害也加大，油路系統出現問題或機油選用不當，導致活塞與氣缸之間潤滑不良，無法給活塞及氣缸提供足夠的油膜的保護，造成磨損、劃傷。
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、山東裝載機發動機大修后，沒有磨合好就長時間高速或超負荷運轉，部件磨合不完全，磨損加大，磨損產生的碎屑還會對氣缸和活塞造成二次傷害。
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、山東裝載機http://www.sgx498.com/空氣濾清系統出現問題，空氣雜質混入燃燒室后附著在汽缸壁上，雜質在燃燒中碳化，變成顆粒，傷害氣缸和活塞，長期超載低速運行，加大對活塞和氣缸的磨損。
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 .
