1、 箱的選用
液壓(ya)(ya)(ya)在液壓(ya)(ya)(ya)系統(tong)中的主要作用(yong)(yong)為儲油(you)(you)(you)(you)、散(san)熱、分離(li)油(you)(you)(you)(you)中所含(han)及(ji)消除泡沫。選用(yong)(yong)油(you)(you)(you)(you)箱(xiang)首先(xian)要考(kao)慮其(qi)容量(liang)，一般移(yi)動式設備(bei)取(qu)泵(beng)最大流(liu)量(liang)的2～3倍(bei)，固定式設備(bei)取(qu)3～4倍(bei)；其(qi)次考(kao)慮油(you)(you)(you)(you)箱(xiang)油(you)(you)(you)(you)位(wei)(wei)，當(dang)系統(tong)全部液壓(ya)(ya)(ya)伸出后油(you)(you)(you)(you)箱(xiang)油(you)(you)(you)(you)面(mian)不得低于最低油(you)(you)(you)(you)位(wei)(wei)，當(dang)油(you)(you)(you)(you)缸回(hui)縮以后油(you)(you)(you)(you)面(mian)不得高于最高油(you)(you)(you)(you)位(wei)(wei)；最后考(kao)慮油(you)(you)(you)(you)箱(xiang)結構(gou)，傳統(tong)油(you)(you)(you)(you)箱(xiang)內的隔(ge)板(ban)(ban)并不能起沉淀(dian)臟物的作用(yong)(yong)，應沿油(you)(you)(you)(you)箱(xiang)縱(zong)軸線安裝(zhuang)一個垂直隔(ge)板(ban)(ban)。此(ci)隔(ge)板(ban)(ban)一端和(he)油(you)(you)(you)(you)箱(xiang)端板(ban)(ban)之間(jian)留有(you)空位(wei)(wei)使隔(ge)板(ban)(ban)兩邊空間(jian)連通，液壓(ya)(ya)(ya)泵(beng)的進(jin)出油(you)(you)(you)(you)口布置在不連通的一端隔(ge)板(ban)(ban)兩側(ce)，使進(jin)油(you)(you)(you)(you)和(he)回(hui)油(you)(you)(you)(you)之間(jian)的距離(li)最遠，液壓(ya)(ya)(ya)油(you)(you)(you)(you)箱(xiang)多起一些散(san)熱作用(yong)(yong)。
2、 液壓油箱的安(an)裝
按(an)照安裝位(wei)置的不同可分為(wei)上置式(shi)(shi)、側置式(shi)(shi)和下(xia)置式(shi)(shi)。
上(shang)(shang)置式(shi)油箱把液壓泵等裝置安裝在有較好剛度(du)的(de)上(shang)(shang)蓋板上(shang)(shang)，其結構(gou)緊(jin)湊(cou)、應用(yong)最廣。此外(wai)還可在油箱外(wai)殼上(shang)(shang)鑄出散(san)熱翅片，加(jia)強散(san)熱效果，即提高了液壓泵的(de)使用(yong)壽(shou)命。
側置(zhi)式(shi)(shi)油(you)(you)箱是(shi)把液(ye)壓(ya)泵等(deng)裝置(zhi)安裝在油(you)(you)箱旁邊(bian)，占地面積雖大，但安裝與(yu)維修都很(hen)方便，通(tong)常(chang)在系統流(liu)量(liang)和油(you)(you)箱容量(liang)較(jiao)(jiao)大時采用，尤其是(shi)當一個油(you)(you)箱給多臺液(ye)壓(ya)泵供油(you)(you)時使(shi)用。因側置(zhi)式(shi)(shi)油(you)(you)箱油(you)(you)位高(gao)于液(ye)壓(ya)泵吸油(you)(you)口(kou)，故(gu)具有較(jiao)(jiao)好的吸油(you)(you)效(xiao)果。
下置(zhi)式油箱(xiang)是把(ba)液(ye)壓泵置(zhi)于油箱(xiang)底下，不(bu)僅便(bian)于安裝和維(wei)修，而(er)且液(ye)壓泵吸入能力大為改善。
