1、液壓密封件之形式選擇
在液壓係統中，常見的密封形式有擠壓型O形密封圈、Y形圈、V形圈、U形圈唇形密封。唇形密封圈主要用於往複動密封，與O形圈等擠壓密封相比，往複動密封使用唇形密封圈具有更好的綜合性能和更長的使用壽命。

2、液壓密封件之材料選擇
密(mi)封(feng)件(jian)形(xing)式(shi)和(he)結(jie)構(gou)現(xian)在(zai)一(yi)般(ban)已(yi)經(jing)定(ding)型(xing)，各(ge)密(mi)封(feng)件(jian)質(zhi)量(liang)區(qu)別(bie)主(zhu)要(yao)在(zai)於(yu)製(zhi)作(zuo)材(cai)料(liao)上(shang)。密(mi)封(feng)材(cai)料(liao)主(zhu)要(yao)使(shi)用(yong)橡(xiang)膠(jiao)和(he)合(he)成(cheng)樹(shu)脂(zhi)。由(you)於(yu)各(ge)種(zhong)材(cai)料(liao)性(xing)能(neng)特(te)點(dian)不(bu)同(tong)，性(xing)能(neng)特(te)點(dian)不(bu)同(tong)，用(yong)途(tu)也(ye)就(jiu)有(you)所(suo)不(bu)同(tong)。選(xuan)用(yong)時(shi)需(xu)根(gen)據(ju)不(bu)同(tong)的(de)使(shi)用(yong)條(tiao)件(jian)和(he)不(bu)同(tong)的(de)使(shi)用(yong)條(tiao)件(jian)作(zuo)出(chu)合(he)適(shi)的(de)選(xuan)擇(ze)。另(ling)外(wai)，某(mou)一(yi)材(cai)質(zhi)的(de)密(mi)封(feng)對(dui)被(bei)密(mi)封(feng)的(de)某(mou)一(yi)工(gong)作(zuo)介(jie)質(zhi)(如礦物油等)表biao現xian較jiao好hao的de密mi封feng性xing能neng，而er對dui另ling一yi介jie質zhi表biao現xian極ji差cha，這zhe就jiu是shi密mi封feng材cai料liao與yu液ye壓ya油you的de相xiang容rong性xing。還hai有you，各ge種zhong不bu同tong的de密mi封feng材cai料liao對dui你ni不bu同tong的de工gong作zuo條tiao件jian表biao現xian出chu不bu同tong的de性xing能neng。有you些xie耐nai熱re，有you些xie不bu耐nai熱re;有些耐酸，有些耐堿，有些耐水，有些耐油;有些抗熱，有些耐低溫，有些耐高溫，等等。這些因素在考慮密封件材料的時候需注意。
