山東裝載機(jī)http://m.hdwzhs.com/發(fā)動(dòng)機(jī)拉缸是指活塞與汽缸相互運(yùn)動(dòng)造成嚴(yán)重表面損傷，損傷原因大多是由于運(yùn)動(dòng)部位的潤(rùn)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(jī)械的有關(guān)專(zhuān)家就給大家詳細(xì)分析一下。
　　
1、山東裝載機(jī)活塞與氣缸配合間隙過(guò)小，導(dǎo)致磨損加劇，雜物進(jìn)入后，造成的磨損傷害也加大，油路系統(tǒng)出現(xiàn)問(wèn)題或機(jī)油選用不當(dāng)，導(dǎo)致活塞與氣缸之間潤(rùn)滑不良，無(wú)法給活塞及氣缸提供足夠的油膜的保護(hù)，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(jī)發(fā)動(dòng)機(jī)大修后，沒(méi)有磨合好就長(zhǎng)時(shí)間高速或超負(fù)荷運(yùn)轉(zhuǎn)，部件磨合不完全，磨損加大，磨損產(chǎn)生的碎屑還會(huì)對(duì)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(jī)http://m.hdwzhs.com/空氣濾清系統(tǒng)出現(xiàn)問(wèn)題，空氣雜質(zhì)混入燃燒室后附著在汽缸壁上，雜質(zhì)在燃燒中碳化，變成顆粒，傷害氣缸和活塞，長(zhǎng)期超載低速運(yùn)行，加大對(duì)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 .
