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);
4、抗拉強度

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。
