②运(yun)行(xing)中产生的(de)异(yi)物a.由于缓冲柱(zhu)塞别劲而形成的(de)摩擦铁粉(fen)或(huo)(huo)铁屑。缓冲装(zhuang)(zhuang)(zhuang)置的(de)配(pei)合间隙很(hen)小，活(huo)塞杆上所受横(heng)向载荷很(hen)大时(shi)，可能(neng)引起烧结(jie)现(xian)象。这些摩擦铁粉(fen)或(huo)(huo)者因(yin)烧结(jie)而产生的(de)已脱(tuo)落掉的(de)金属碎片将留(liu)在(zai)缸(gang)内(nei)。b.缸(gang)壁内(nei)表面的(de)伤痕。活(huo)塞的(de)滑动表面压(ya)力高(gao)，引起烧结(jie)现(xian)象，于是缸(gang)体内(nei)表面发(fa)生挤(ji)裂，被(bei)挤(ji)裂的(de)金属脱(tuo)落，留(liu)在(zai)缸(gang)内(nei)，会造成伤痕。③从管(guan)路(lu)进入的(de)异(yi)物，有(you)多种(zhong)情况。a.清(qing)洗时(shi)不注意。管(guan)路(lu)安装(zhuang)(zhuang)(zhuang)好以后进行(xing)清(qing)洗时(shi)，不应通过缸(gang)体，必(bi)须在(zai)缸(gang)体的(de)油口前边加装(zhuang)(zhuang)(zhuang)旁(pang)通管(guan)路(lu)。这一点(dian)很(hen)重要(yao)。否(fou)则，管(guan)路(lu)中的(de)异(yi)物将进入缸(gang)内(nei)，一旦进入，即难以向外(wai)排(pai)除，反而变(bian)成向缸(gang)体内(nei)输送异(yi)物了。再者，清(qing)洗时(shi)要(yao)考虑安装(zhuang)(zhuang)(zhuang)管(guan)路(lu)操(cao)作(zuo)中所进异(yi)物的(de)取出方法。此外(wai)，对管(guan)内(nei)的(de)腐蚀(shi)等(deng)在(zai)管(guan)路(lu)安装(zhuang)(zhuang)(zhuang)之前即应进行(xing)酸洗等(deng)手续，必(bi)须完全去掉锈蚀(shi)。茂名(ming)自锁液(ye)压(ya)液(ye)压(ya)油缸(gang)按结(jie)构形式(shi)可分(fen)为(wei)活(huo)塞式(shi)、柱(zhu)塞式(shi)、多级伸(shen)缩套(tao)筒式(shi)，齿轮(lun)齿条式(shi)等(deng)；

异物(wu)(wu)(wu)进入缸(gang)内(nei)的(de)(de)途(tu)径(jing)有(you)(you)下(xia)列几种。①进入缸(gang)内(nei)的(de)(de)异物(wu)(wu)(wu)a.由于保管(guan)时(shi)(shi)不(bu)注(zhu)意使(shi)油(you)口敞开着(zhe)，将产生(sheng)时(shi)(shi)刻接受异物(wu)(wu)(wu)的(de)(de)条件，这是(shi) 不(bu)允许的(de)(de)。保管(guan)时(shi)(shi)必(bi)须(xu)注(zhu)入防锈油(you)或者工(gong)作(zuo)油(you)液，并(bing)且塞好(hao)。b.缸(gang)体安(an)装时(shi)(shi)进入异物(wu)(wu)(wu)。进行安(an)装操作(zuo)的(de)(de)场所，条件不(bu)好(hao)，无意识(shi)中即可进入异物(wu)(wu)(wu)。因此(ci)安(an)装地点(dian)周围必(bi)须(xu)整(zheng)理干净(jing)，尤其(qi)是(shi)安(an)放(fang)零(ling)件的(de)(de)地方一定要清扫干净(jing)，不(bu)使(shi)其(qi)存在脏(zang)物(wu)(wu)(wu)。c.零(ling)件上有(you)(you)"毛刺"，或擦洗不(bu)充(chong)分。缸(gang)盖上的(de)(de)油(you)口或缓冲装置(zhi)内(nei)常有(you)(you)钻孔(kong)加(jia)工(gong)时(shi)(shi)留下(xia)的(de)(de)毛刺，应(ying)加(jia)以注(zhu)意，在砂研去除(chu)后(hou)再行安(an)装。
