大型液壓站的規模大小，可劃分為三類。規模較小的單機型液壓站，通常為動力型或復合型整體式液(ye)(ye)(ye)壓(ya)站(zhan)。中(zhong)等規模的(de)機組(zu)型液(ye)(ye)(ye)壓(ya)站(zhan)，則(ze)多采(cai)用復合型分離式結構(gou)。中(zhong)央型液(ye)(ye)(ye)壓(ya)站(zhan)是(shi)大規模的(de)液(ye)(ye)(ye)壓(ya)站(zhan)，高置這種液(ye)(ye)(ye)壓(ya)站(zhan)可以對液(ye)(ye)(ye)壓(ya)系統進行集中(zhong)管理。

大(da)型液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)站(zhan)(zhan)按照通用(yong)(yong)(yong)(yong)性(xing)程(cheng)度可將(jiang)液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)站(zhan)(zhan)分為(wei)專(zhuan)用(yong)(yong)(yong)(yong)液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)站(zhan)(zhan)和通用(yong)(yong)(yong)(yong)液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)站(zhan)(zhan)兩(liang)類(lei)。工業設備(bei)(bei)所(suo)用(yong)(yong)(yong)(yong)的(de)液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)站(zhan)(zhan)都是根據主機(ji)的(de)某種工藝目的(de)專(zhuan)門設計和制(zhi)(zhi)造的(de)，一(yi)(yi)般(ban)不具有(you)通用(yong)(yong)(yong)(yong)性(xing)，屬于專(zhuan)用(yong)(yong)(yong)(yong)液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)站(zhan)(zhan)范疇。針對現代(dai)機(ji)械設備(bei)(bei)的(de)一(yi)(yi)些共性(xing)特和使用(yong)(yong)(yong)(yong)要(yao)求，近年來，有(you)些液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)制(zhi)(zhi)造商(shang)還(huan)為(wei)用(yong)(yong)(yong)(yong)戶提供一(yi)(yi)類(lei)通用(yong)(yong)(yong)(yong)化液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)裝(zhuang)置(zhi)。這類(lei)通用(yong)(yong)(yong)(yong)化液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)裝(zhuang)置(zhi)常將(jiang)大(da)部分控制(zhi)(zhi)元(yuan)(yuan)件與液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵及其驅動電機(ji)，油箱等集(ji)成(cheng)在一(yi)(yi)起，這種液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)裝(zhuang)置(zhi)稱為(wei)液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)多功能液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)工作站(zhan)(zhan)。這類(lei)液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)裝(zhuang)置(zhi)一(yi)(yi)般(ban)為(wei)便攜式(shi)結構，體積與重量較(jiao)小(xiao)，一(yi)(yi)般(ban)由液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)元(yuan)(yuan)件廠專(zhuan)門生產(chan)。
