O形密封圈長處與加工

O形(xing)(xing)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)圈(quan)(quan)是用丁腈橡膠(jiao)(jiao)、硅膠(jiao)(jiao)、氟(fu)膠(jiao)(jiao)原料制成，用于液(ye)壓(ya)氣動(dong)元(yuan)(yuan)件的(de)(de)動(dong)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)活塞密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)、活塞桿密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)和靜(jing)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)軸向密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)。它是液(ye)壓(ya)工程中(zhong)(zhong)運(yun)用最廣泛的(de)(de)一種密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)件僅限(xian)于低速反轉密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)設(she)備(bei)。O形(xing)(xing)圈(quan)(quan)是安裝在(zai)溝槽中(zhong)(zhong)，適量緊縮(suo)(suo)的(de)(de)O形(xing)(xing)截(jie)面(mian)(mian)的(de)(de)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)環(huan)。衡水高(gao)科橡塑制品(pin)有限(xian)廠家(jia)的(de)(de)O形(xing)(xing)圈(quan)(quan)在(zai)模具中(zhong)(zhong)硫化成形(xing)(xing)，其(qi)尺(chi)(chi)度常用其(qi)內徑和截(jie)面(mian)(mian)直徑來定(ding)義。與(yu)(yu)其(qi)他密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)元(yuan)(yuan)件相比，O形(xing)(xing)圈(quan)(quan)有很多長處：1、構(gou)(gou)造細(xi)巧，裝拆便利(li)。2、價格低廉，體積(ji)小(xiao)。3、很多規(gui)范(fan)尺(chi)(chi)度在(zai)全球規(gui)模可供現貨(huo)，便利(li)維護與(yu)(yu)修理(li)。O形(xing)(xing)圈(quan)(quan)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)規(gui)劃(hua)(hua)的(de)(de)主要內容是截(jie)面(mian)(mian)直徑的(de)(de)緊縮(suo)(suo)率和拉伸(shen)(shen)，對(dui)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)功能和運(yun)用壽命有重(zhong)要意(yi)義。想要O形(xing)(xing)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)圈(quan)(quan)構(gou)(gou)成杰出的(de)(de)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)作(zuo)用，就(jiu)(jiu)要構(gou)(gou)成合理(li)的(de)(de)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)圈(quan)(quan)緊縮(suo)(suo)量與(yu)(yu)拉伸(shen)(shen)量，那么(me)O形(xing)(xing)圈(quan)(quan)尺(chi)(chi)度與(yu)(yu)溝槽尺(chi)(chi)度的(de)(de)準確匹配就(jiu)(jiu)變成了重(zhong)要的(de)(de)要素。密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)設(she)備(bei)規(gui)劃(hua)(hua)加工時，O形(xing)(xing)圈(quan)(quan)緊縮(suo)(suo)量過(guo)大則會致使O形(xing)(xing)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)圈(quan)(quan)橡膠(jiao)(jiao)應(ying)力松(song)懈(xie)而導(dao)致走漏(lou)；緊縮(suo)(suo)量過(guo)小(xiao)，就(jiu)(jiu)會導(dao)致走漏(lou)。同樣(yang)，O形(xing)(xing)圈(quan)(quan)工作(zuo)中(zhong)(zhong)拉伸(shen)(shen)過(guo)度，也會加快老化而導(dao)致走漏(lou)。世界各國的(de)(de)規(gui)范(fan)對(dui)此都(dou)有較嚴厲的(de)(de)規(gui)定(ding)。
