一、前言缸套与活塞环在工作时,承受着350℃左右的高温和40～80公斤/厘米~2高压气流的作用。活塞环还以0.7～2.6公斤/厘米~2的彈性压力和每分钟2000～4000次的高速往复运动与缸套进行磨擦,这种磨擦在缸套上部是干式和半干式,它使环与缸壁产生强烈的刮削、疲劳和粘附磨損。湿式缸套的外部还直接与冷却水接触,使缸套內壁受高温气体循环加热,外壁受水冷却。缸套內壁凝成的湿气,又与燃料和潤滑油在汽缸內的燃燒殘留物(无水酸)結合成酸,使缸套和活塞
First, the foreword Cylinder liner and piston ring at work, bear the high temperature of about 350 ℃ and 40 ~ 80 kg / cm ~ 2 high-pressure air flow role. Piston ring also with 0.7 ~ 2.6 kg / cm ~ 2 elastic pressure and 2000 ~ 4000 times per minute high-speed reciprocating motion and cylinder liner friction, the friction in the upper cylinder liner is dry and semi-dry, it makes the ring Strong shaving, fatigue and adhesive wear with cylinder wall. The outer part of the wet liner is also in direct contact with the cooling water, so that the inner wall of the liner is heated by the high temperature gas circulation and the outer wall is cooled by water. Condensed moisture inside the liner wall, but also with the fuel and lubricating oil in the cylinder combustion residues (anhydrous acid) combined into acid, so that the cylinder liner and piston
