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
密(mi)封(feng)件(jian)的(de)工(gong)作(zuo)溫(wen)度(du)取(qu)決(jue)於(yu)密(mi)封(feng)介(jie)質(zhi)的(de)溫(wen)度(du)及(ji)密(mi)封(feng)件(jian)本(ben)身(shen)在(zai)運(yun)動(dong)過(guo)程(cheng)中(zhong)的(de)溫(wen)升(sheng)。溫(wen)度(du)直(zhi)接(jie)影(ying)響(xiang)密(mi)封(feng)性(xing)能(neng)。過(guo)高(gao)的(de)溫(wen)度(du)往(wang)往(wang)會(hui)加(jia)速(su)密(mi)封(feng)材(cai)料(liao)的(de)老(lao)化(hua)，降(jiang)低(di)材(cai)料(liao)的(de)彈(dan)性(xing)、硬度等性能，發生材料硬化;溫度過低也會導致材料加速硬化，失去彈性性能，降低了材料的密封效果。綜上所述，應采用有一定使用溫度範圍的材料。
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);
