液壓密封技術的好壞會影響液壓支架的工作質量和壽命。那麼液壓密封件產品應該具備哪些性能呢?
1、耐溫性能

2、耐介質性

3、耐磨性能
材cai料liao的de耐nai磨mo特te性xing是shi動dong密mi封feng的de重zhong要yao性xing能neng指zhi標biao之zhi一yi。耐nai磨mo性xing好hao，則ze使shi用yong壽shou命ming長chang。材cai料liao耐nai磨mo性xing能neng與yu材cai料liao的de硬ying度du有you著zhe密mi切qie的de聯lian係xi，材cai料liao硬ying度du越yue高gao耐nai磨mo性xing越yue好hao，使shi用yong壽shou命ming越yue長chang;

6、彈性
所(suo)謂(wei)擠(ji)壓(ya)型(xing)密(mi)封(feng)就(jiu)是(shi)指(zhi)依(yi)靠(kao)密(mi)封(feng)材(cai)料(liao)受(shou)壓(ya)後(hou)自(zi)身(shen)產(chan)生(sheng)的(de)回(hui)彈(dan)力(li)而(er)得(de)到(dao)密(mi)封(feng)能(neng)力(li)的(de)一(yi)種(zhong)密(mi)封(feng)方(fang)式(shi)。因(yin)為(wei)唇(chun)形(xing)密(mi)封(feng)可(ke)能(neng)存(cun)在(zai)一(yi)定(ding)量(liang)的(de)偏(pian)心(xin)，所(suo)以(yi)需(xu)要(yao)依(yi)靠(kao)材(cai)料(liao)的(de)彈(dan)性(xing)來(lai)補(bu)償(chang)密(mi)封(feng)的(de)接(jie)觸(chu)應(ying)力(li)不(bu)足(zu)等(deng)問(wen)題(ti)。所(suo)以(yi)，材(cai)料(liao)的(de)彈(dan)性(xing)對(dui)於(yu)密(mi)封(feng)效(xiao)果(guo)的(de)好(hao)壞(huai)至(zhi)關(guan)重(zhong)要(yao);
7、硬度
硬ying度du是shi密mi封feng材cai料liao的de重zhong要yao指zhi標biao，主zhu要yao根gen據ju密mi封feng麵mian的de粗cu糙cao度du來lai確que定ding。當dang密mi封feng麵mian比bi較jiao粗cu糙cao時shi，密mi封feng件jian的de硬ying度du要yao低di，這zhe樣yang才cai能neng保bao證zheng密mi封feng效xiao果guo好hao。密mi封feng壓ya力li比bi較jiao高gao的de部bu位wei，則ze要yao求qiu適shi當dang提ti高gao密mi封feng件jian的de硬ying度du，這zhe樣yang可ke以yi防fang密mi封feng件jian過guo度du變bian形xing，防fang止zhi發fa生sheng密mi封feng件jian被bei擠ji出chu的de現xian象xiang。此ci外wai，材cai料liao硬ying度du有you隨sui使shi用yong溫wen度du升sheng高gao而er下xia降jiang的de特te點dian，並bing且qie硬ying度du高gao，材cai料liao的de耐nai磨mo性xing能neng也ye強qiang。
