如何評價O型(xing)密(mi)(mi)封(feng)(feng)的(de)(de)(de)(de)(de)能力呢？分兩步走：1，首先評價O型(xing)密(mi)(mi)封(feng)(feng)圈(quan)的(de)(de)(de)(de)(de)強度。O型(xing)密(mi)(mi)封(feng)(feng)是為(wei)補償結(jie)構(gou)件(jian)的(de)(de)(de)(de)(de)公差(cha)而設計，由于設計或(huo)者結(jie)構(gou)件(jian)相(xiang)對運動的(de)(de)(de)(de)(de)原(yuan)因使得(de)在結(jie)構(gou)件(jian)產(chan)生了配合間(jian)隙(xi)，為(wei)滿(man)足實際工況需要，O型(xing)密(mi)(mi)封(feng)(feng)圈(quan)需要變形(xing)(xing)而填充(chong)整個空間(jian)。不管怎么(me)變形(xing)(xing)，其橫截(jie)面(mian)上主要受到結(jie)構(gou)件(jian)的(de)(de)(de)(de)(de)剪切(qie)(qie)力使其變形(xing)(xing)（受壓和(he)受拉(la)變形(xing)(xing)相(xiang)對較(jiao)小），由此(ci)，需要評估O型(xing)圈(quan)的(de)(de)(de)(de)(de)剪切(qie)(qie)強度。其剪切(qie)(qie)力由結(jie)構(gou)件(jian)件(jian)的(de)(de)(de)(de)(de)剪切(qie)(qie)載荷(he)作(zuo)為(wei)外載，O型(xing)圈(quan)的(de)(de)(de)(de)(de)橫截(jie)面(mian)積作(zuo)為(wei)剪切(qie)(qie)面(mian)，獲(huo)得(de)的(de)(de)(de)(de)(de)剪切(qie)(qie)應力和(he)O型(xing)圈(quan)的(de)(de)(de)(de)(de)剪切(qie)(qie)強度進行比較(jiao)；安徽o型(xing)密(mi)(mi)封(feng)(feng)件(jian)價格有時也可以采用浸透潤滑(hua)油(you)(you)的(de)(de)(de)(de)(de)氈圈(quan)式加(jia)油(you)(you)裝置。

油壓(ya)缸(gang)如何(he)選(xuan)擇適合的密(mi)(mi)封(feng)(feng)(feng)圈？液(ye)壓(ya)缸(gang)用密(mi)(mi)封(feng)(feng)(feng)圈在輕載運(yun)用中(zhong)(zhong)，單獨密(mi)(mi)封(feng)(feng)(feng)元(yuan)器件(jian)(jian)沒法保證零泄(xie)露和(he)(he)長期性使用期限。因(yin)為油壓(ya)缸(gang)的液(ye)壓(ya)缸(gang)立(li)即裸露于外(wai)部自然環境中(zhong)(zhong)，因(yin)而防止泄(xie)漏尤為重要。解決(jue)方法是串(chuan)連系(xi)(xi)統(tong)(tong)(tong)。該系(xi)(xi)統(tong)(tong)(tong)中(zhong)(zhong)的每一(yi)個(ge)密(mi)(mi)封(feng)(feng)(feng)件(jian)(jian)都(dou)是有其特殊(shu)的作用，而且(qie)要確保每一(yi)個(ge)元(yuan)器件(jian)(jian)間的相互影響(xiang)能產(chan)生一(yi)個(ge)性能的密(mi)(mi)封(feng)(feng)(feng)系(xi)(xi)統(tong)(tong)(tong)。串(chuan)連密(mi)(mi)封(feng)(feng)(feng)系(xi)(xi)統(tong)(tong)(tong)這兒強烈(lie)推薦二種(zhong)關鍵配備。第一(yi)種(zhong)是單邊聚四氟乙(yi)烯滑(hua)動密(mi)(mi)封(feng)(feng)(feng)做(zuo)為道(dao)(dao)密(mi)(mi)封(feng)(feng)(feng)，含有單邊聚四氟乙(yi)烯或聚氨(an)酯材料(liao)滑(hua)動密(mi)(mi)封(feng)(feng)(feng)做(zuo)為第二道(dao)(dao)密(mi)(mi)封(feng)(feng)(feng)。它可以容許一(yi)層(ceng)薄浮(fu)油根據道(dao)(dao)密(mi)(mi)封(feng)(feng)(feng)，另外(wai)具(ju)備的泵回吸工作能力(li)。可完成零泄(xie)露，低(di)摩(mo)擦(ca)，降低(di)損(sun)壞。此外(wai)，上(shang)邊談(tan)及的第二道(dao)(dao)密(mi)(mi)封(feng)(feng)(feng)件(jian)(jian)具(ju)備出色的滑(hua)動特性和(he)(he)較大耐磨性能。第二種(zhong)配備是BufferSeal，其具(ju)備集成化平墊圈和(he)(he)做(zuo)為第二道(dao)(dao)密(mi)(mi)封(feng)(feng)(feng)的聚氨(an)酯材料(liao)U形(xing)圈。比(bi)第一(yi)種(zhong)更(geng)具(ju)有成本效益，而且(qie)可達到系(xi)(xi)統(tong)(tong)(tong)所必(bi)須的高耐磨性能或工作壓(ya)力(li)轉變。升級之(zhi)后(hou)的BufferSeal也能為U形(xing)圈出示潤化，防止干摩(mo)擦(ca)運(yun)作。
