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
因yin為wei材cai料liao在zai介jie質zhi中zhong的de溶rong脹zhang程cheng度du是shi密mi封feng性xing能neng好hao壞huai的de關guan鍵jian因yin素su，所suo以yi在zai選xuan擇ze液ye壓ya密mi封feng件jian材cai料liao時shi，第di一yi要yao考kao慮lv的de因yin素su是shi所suo選xuan擇ze的de材cai料liao能neng否fou很hen好hao地di與yu密mi封feng介jie質zhi相xiang容rong;如(ru)果(guo)密(mi)封(feng)材(cai)料(liao)和(he)密(mi)封(feng)流(liu)體(ti)相(xiang)容(rong)，會(hui)導(dao)致(zhi)密(mi)封(feng)件(jian)膨(peng)脹(zhang)或(huo)收(shou)縮(suo)，在(zai)使(shi)用(yong)初(chu)期(qi)就(jiu)發(fa)生(sheng)故(gu)障(zhang)。密(mi)封(feng)件(jian)膨(peng)脹(zhang)引(yin)起(qi)摩(mo)擦(ca)阻(zu)力(li)增(zeng)加(jia)，同(tong)時(shi)會(hui)使(shi)密(mi)封(feng)件(jian)滾(gun)動(dong)。密(mi)封(feng)件(jian)收(shou)縮(suo)會(hui)引(yin)起(qi)預(yu)壓(ya)量(liang)減(jian)少(shao)，偏(pian)心(xin)補(bu)償(chang)能(neng)力(li)降(jiang)低(di)，直(zhi)至(zhi)泄(xie)漏(lou)。
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;
4、抗拉強度

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。
