一(yi)般(ban)地說，測(ce)量(liang)(liang)(liang)時造(zao)成深度不(bu)大(da)的(de)細長形(xing)劃(hua)傷(shang)是(shi)輕(qing)微(wei)的(de)，不(bu)影響運(yun)行精(jing)度，但如果測(ce)量(liang)(liang)(liang)桿頭(tou)(tou)尺寸調節(jie)不(bu)當，測(ce)量(liang)(liang)(liang)觸頭(tou)(tou)硬行嵌(qian)入(ru)，會造(zao)成較為重(zhong)度的(de)傷(shang)痕(hen)(hen)。解(jie)決此(ci)問題的(de)對策，首(shou)先是(shi)測(ce)量(liang)(liang)(liang)出調節(jie)好的(de)測(ce)量(liang)(liang)(liang)頭(tou)(tou)的(de)長短(duan)度，此(ci)外，用(yong)一(yi)張只在(zai)測(ce)量(liang)(liang)(liang)位置上(shang)開孔的(de)紙帶，貼在(zai)缸壁內表面(mian)，即不(bu)會產生上(shang)述(shu)形(xing)狀(zhuang)劃(hua)痕(hen)(hen)。測(ce)量(liang)(liang)(liang)造(zao)成的(de)輕(qing)微(wei)劃(hua)痕(hen)(hen)，一(yi)般(ban)用(yong)舊砂布(bu)的(de)反(fan)面(mian)或馬糞紙即可擦去。
液壓(ya)缸(gang)結構基本上可以分為缸(gang)筒(tong)和(he)(he)缸(gang)蓋、活塞(sai)和(he)(he)活塞(sai)桿、密封(feng)裝置、緩沖裝置和(he)(he)排氣裝置五(wu)個部分。今(jin)天威海力建小編著(zhu)重帶(dai)著(zhu)大家了解一(yi)下缸(gang)筒(tong)和(he)(he)缸(gang)蓋。
缸筒(tong)和缸蓋
一(yi)般來說，缸筒(tong)(tong)(tong)(tong)和缸蓋的(de)(de)結構(gou)(gou)形(xing)(xing)式(shi)和其(qi)使(shi)用(yong)(yong)(yong)的(de)(de)材料有關。工(gong)(gong)作(zuo)壓力p＜10MPa時(shi)，使(shi)用(yong)(yong)(yong)鑄鐵；p＜20MPa時(shi)，使(shi)用(yong)(yong)(yong)無(wu)縫鋼管(guan)；p＞20MPa時(shi)，使(shi)用(yong)(yong)(yong)鑄鋼或(huo)(huo)鍛(duan)鋼。法蘭連接式(shi)，結構(gou)(gou)簡單，容(rong)(rong)易加(jia)(jia)工(gong)(gong)，也容(rong)(rong)易裝(zhuang)拆，但(dan)外形(xing)(xing)尺(chi)寸(cun)和重(zhong)(zhong)量都(dou)較(jiao)大(da)(da)，常用(yong)(yong)(yong)于(yu)(yu)鑄鐵制(zhi)的(de)(de)缸筒(tong)(tong)(tong)(tong)上。半環連接式(shi)，它(ta)的(de)(de)缸筒(tong)(tong)(tong)(tong)壁部因(yin)開了(le)環形(xing)(xing)槽(cao)而削弱了(le)強度，為此(ci)有時(shi)要加(jia)(jia)厚缸壁，它(ta)容(rong)(rong)易加(jia)(jia)工(gong)(gong)和裝(zhuang)拆，重(zhong)(zhong)量較(jiao)輕(qing)，常用(yong)(yong)(yong)于(yu)(yu)無(wu)縫鋼管(guan)或(huo)(huo)鍛(duan)鋼制(zhi)的(de)(de)缸筒(tong)(tong)(tong)(tong)上。螺紋連接式(shi)，它(ta)的(de)(de)缸筒(tong)(tong)(tong)(tong)端部結構(gou)(gou)復(fu)雜，外徑加(jia)(jia)工(gong)(gong)時(shi)要求(qiu)保證內(nei)外徑同心，裝(zhuang)拆要使(shi)用(yong)(yong)(yong)工(gong)(gong)具(ju)，它(ta)的(de)(de)外形(xing)(xing)尺(chi)寸(cun)和重(zhong)(zhong)量都(dou)較(jiao)小(xiao)，常用(yong)(yong)(yong)于(yu)(yu)無(wu)縫鋼管(guan)或(huo)(huo)鑄鋼制(zhi)的(de)(de)缸筒(tong)(tong)(tong)(tong)上。拉桿(gan)連接式(shi)，結構(gou)(gou)的(de)(de)通用(yong)(yong)(yong)性大(da)(da)，容(rong)(rong)易加(jia)(jia)工(gong)(gong)和裝(zhuang)拆，但(dan)外形(xing)(xing)尺(chi)寸(cun)較(jiao)大(da)(da)，且較(jiao)重(zhong)(zhong)。焊接連接式(shi)，結構(gou)(gou)簡單，尺(chi)寸(cun)小(xiao)，但(dan)缸底處(chu)內(nei)徑不易加(jia)(jia)工(gong)(gong)，且可能引起變形(xing)(xing)。
液(ye)壓缸泄漏帶來的(de)危害很多(duo)，既是液(ye)壓缸產生各種故障的(de)原(yuan)因之一(yi)，又是影響(xiang)安(an)全(quan)、污染(ran)環(huan)境的(de)重要因素，所(suo)以應引起足夠的(de)重視。
液壓(ya)(ya)缸(gang)的泄(xie)(xie)漏(lou)包括(kuo)外(wai)(wai)泄(xie)(xie)漏(lou)和外(wai)(wai)泄(xie)(xie)漏(lou)兩種情況。外(wai)(wai)泄(xie)(xie)漏(lou)是指液壓(ya)(ya)缸(gang)缸(gang)筒和缸(gang)蓋、缸(gang)底(di)、油口、排氣閥、緩(huan)沖調節(jie)閥、缸(gang)蓋與活(huo)塞(sai)(sai)桿處(chu)等外(wai)(wai)部的漏(lou)油，容易從外(wai)(wai)部直接觀察(cha)出。內(nei)(nei)泄(xie)(xie)漏(lou)是指液壓(ya)(ya)缸(gang)內(nei)(nei)部高壓(ya)(ya)腔的壓(ya)(ya)力油向低壓(ya)(ya)腔滲漏(lou)，它發(fa)生在活(huo)塞(sai)(sai)與缸(gang)內(nei)(nei)壁、活(huo)塞(sai)(sai)內(nei)(nei)孔與活(huo)塞(sai)(sai)桿連(lian)接處(chu)。內(nei)(nei)泄(xie)(xie)漏(lou)不(bu)能(neng)直接觀察(cha)到(dao)。不(bu)論是內(nei)(nei)泄(xie)(xie)漏(lou)和外(wai)(wai)泄(xie)(xie)漏(lou)，其泄(xie)(xie)漏(lou)的原因主要是密封不(bu)良(liang)、連(lian)接處(chu)接觸不(bu)良(liang)等。
