②运行中(zhong)产生的异(yi)物(wu)a.由于缓冲柱塞(sai)(sai)别(bie)劲而(er)形成的摩擦铁粉(fen)或(huo)(huo)铁屑。缓冲装(zhuang)置的配合间(jian)隙(xi)很(hen)(hen)小，活(huo)塞(sai)(sai)杆上所受(shou)横向(xiang)载荷(he)很(hen)(hen)大时(shi)，可能引(yin)起烧结(jie)现(xian)象。这些(xie)摩擦铁粉(fen)或(huo)(huo)者因烧结(jie)而(er)产生的已脱落掉的金(jin)属碎片将留(liu)(liu)在缸(gang)(gang)(gang)内(nei)(nei)。b.缸(gang)(gang)(gang)壁内(nei)(nei)表(biao)面的伤痕(hen)。活(huo)塞(sai)(sai)的滑动表(biao)面压(ya)力高，引(yin)起烧结(jie)现(xian)象，于是缸(gang)(gang)(gang)体(ti)内(nei)(nei)表(biao)面发生挤裂，被(bei)挤裂的金(jin)属脱落，留(liu)(liu)在缸(gang)(gang)(gang)内(nei)(nei)，会造成伤痕(hen)。③从管路进(jin)入的异(yi)物(wu)，有(you)多(duo)种情况(kuang)。a.清(qing)洗(xi)时(shi)不(bu)注意(yi)。管路安(an)装(zhuang)好以后进(jin)行清(qing)洗(xi)时(shi)，不(bu)应通过缸(gang)(gang)(gang)体(ti)，必须在缸(gang)(gang)(gang)体(ti)的油口前(qian)边加装(zhuang)旁通管路。这一(yi)点很(hen)(hen)重要(yao)。否则，管路中(zhong)的异(yi)物(wu)将进(jin)入缸(gang)(gang)(gang)内(nei)(nei)，一(yi)旦进(jin)入，即难(nan)以向(xiang)外(wai)排除(chu)，反(fan)而(er)变成向(xiang)缸(gang)(gang)(gang)体(ti)内(nei)(nei)输(shu)送异(yi)物(wu)了。再者，清(qing)洗(xi)时(shi)要(yao)考虑安(an)装(zhuang)管路操作中(zhong)所进(jin)异(yi)物(wu)的取(qu)出方法(fa)。此外(wai)，对管内(nei)(nei)的腐蚀等(deng)在管路安(an)装(zhuang)之前(qian)即应进(jin)行酸洗(xi)等(deng)手续，必须完全(quan)去掉锈蚀。茂名自(zi)锁(suo)液(ye)压(ya)液(ye)压(ya)油缸(gang)(gang)(gang)按结(jie)构(gou)形式可分(fen)为活(huo)塞(sai)(sai)式、柱塞(sai)(sai)式、多(duo)级伸缩套筒式，齿轮齿条式等(deng)；

异(yi)(yi)物进入(ru)缸(gang)(gang)内的(de)途(tu)径有下列几种(zhong)。①进入(ru)缸(gang)(gang)内的(de)异(yi)(yi)物a.由于保管时(shi)不(bu)(bu)注意使油(you)口敞开(kai)着(zhe)，将产生时(shi)刻(ke)接受异(yi)(yi)物的(de)条件(jian)，这是 不(bu)(bu)允许的(de)。保管时(shi)必须注入(ru)防(fang)锈油(you)或(huo)者工作油(you)液，并且塞(sai)好。b.缸(gang)(gang)体安装时(shi)进入(ru)异(yi)(yi)物。进行安装操作的(de)场所，条件(jian)不(bu)(bu)好，无(wu)意识中即可进入(ru)异(yi)(yi)物。因此安装地点(dian)周围(wei)必须整(zheng)理干净，尤其是安放零件(jian)的(de)地方一定要清扫干净，不(bu)(bu)使其存在(zai)脏物。c.零件(jian)上(shang)(shang)有"毛刺"，或(huo)擦(ca)洗不(bu)(bu)充分。缸(gang)(gang)盖上(shang)(shang)的(de)油(you)口或(huo)缓(huan)冲装置内常有钻孔加工时(shi)留(liu)下的(de)毛刺，应(ying)加以注意，在(zai)砂研去除后再(zai)行安装。
