液(ye)(ye)壓千(qian)斤頂(ding)是指采用柱塞或液(ye)(ye)壓缸作為剛性頂(ding)舉件的千(qian)斤頂(ding)。具有結(jie)構緊湊，工作平穩，頂(ding)撐力(li)(li)大，可自鎖等特點(dian)。液(ye)(ye)壓千(qian)斤頂(ding)的撐頂(ding)能力(li)(li)強，重(zhong)型液(ye)(ye)壓千(qian)斤頂(ding)頂(ding)撐力(li)(li)超過100t。

冠航液壓千斤頂(ding)適用于起(qi)(qi)重(zhong)高度不(bu)(bu)大的(de)各種起(qi)(qi)重(zhong)作(zuo)業(ye)。它由油(you)(you)(you)室、油(you)(you)(you)泵(beng)(beng)、儲油(you)(you)(you)腔、活(huo)塞(sai)、搖把、油(you)(you)(you)閥(fa)等主要部(bu)分組成。工(gong)作(zuo)時(shi)，只要往復(fu)扳動搖把，使手動油(you)(you)(you)泵(beng)(beng)不(bu)(bu)斷向油(you)(you)(you)缸(gang)內(nei)(nei)壓(ya)油(you)(you)(you)，由于油(you)(you)(you)缸(gang)內(nei)(nei)油(you)(you)(you)壓(ya)的(de)不(bu)(bu)斷增高，就迫使活(huo)塞(sai)及活(huo)塞(sai)上面的(de)重(zhong)物(wu)一起(qi)(qi)向上運動。打(da)開回(hui)油(you)(you)(you)閥(fa)，油(you)(you)(you)缸(gang)內(nei)(nei)的(de)高壓(ya)油(you)(you)(you)便(bian)流回(hui)儲油(you)(you)(you)腔，于是重(zhong)物(wu)與活(huo)塞(sai)也就一起(qi)(qi)下落。
