Rexroth柱塞泵根據傾斜(xie)(xie)(xie)(xie)元件(jian)的不(bu)同,有斜(xie)(xie)(xie)(xie)盤(pan)式(shi)和斜(xie)(xie)(xie)(xie)軸式(shi)兩(liang)種。斜(xie)(xie)(xie)(xie)盤(pan)式(shi)是斜(xie)(xie)(xie)(xie)盤(pan)相對回轉的缸體有一傾斜(xie)(xie)(xie)(xie)角度,而(er)引起柱塞在泵缸中往復運動。
柱(zhu)塞(sai)泵柱(zhu)塞(sai)往復(fu)運動(dong)總行程L是(shi)不(bu)(bu)變的,由凸(tu)(tu)輪的升程決定。柱(zhu)塞(sai)每循(xun)環的供(gong)(gong)油(you)(you)量大小取決于供(gong)(gong)油(you)(you)行程,供(gong)(gong)油(you)(you)行程不(bu)(bu)受凸(tu)(tu)輪軸(zhou)控制是(shi)可變的。供(gong)(gong)油(you)(you)開始(shi)時(shi)刻不(bu)(bu)隨供(gong)(gong)油(you)(you)行程的變化(hua)而(er)變化(hua)。轉(zhuan)動(dong)柱(zhu)塞(sai)可改變供(gong)(gong)油(you)(you)終了時(shi)刻,從(cong)而(er)改變供(gong)(gong)油(you)(you)量。柱(zhu)塞(sai)泵工作時(shi),在(zai)噴油(you)(you)泵凸(tu)(tu)輪軸(zhou)上的凸(tu)(tu)輪與柱(zhu)塞(sai)彈簧(huang)的作用(yong)下(xia),迫使(shi)柱(zhu)塞(sai)作上、下(xia)往復(fu)運動(dong),從(cong)而(er)完成泵油(you)(you)任務,泵油(you)(you)過程可分為(wei)以下(xia)兩個階段。
進(jin)油(you)過程:當凸(tu)(tu)輪的(de)凸(tu)(tu)起部分轉過去(qu)后(hou),在彈(dan)簧(huang)力的(de)作用下(xia)(xia),柱塞(sai)(sai)向下(xia)(xia)運(yun)動,柱塞(sai)(sai)上部空間(稱為泵(beng)油(you)室)產生真(zhen)空度,當柱塞(sai)(sai)上端面(mian)把柱塞(sai)(sai)套上的(de)進(jin)油(you)孔(kong)打開后(hou),充滿在油(you)泵(beng)上體油(you)道內(nei)的(de)柴(chai)油(you)經油(you)孔(kong)進(jin)入泵(beng)油(you)室,柱塞(sai)(sai)運(yun)動到下(xia)(xia)止點(dian),進(jin)油(you)結束
回油(you)過程:柱(zhu)(zhu)(zhu)塞向(xiang)(xiang)上(shang)(shang)(shang)供(gong)油(you),當(dang)上(shang)(shang)(shang)行(xing)(xing)到柱(zhu)(zhu)(zhu)塞上(shang)(shang)(shang)的(de)(de)(de)斜槽(cao)(停供(gong)邊)與(yu)套筒上(shang)(shang)(shang)的(de)(de)(de)回油(you)孔相通時,泵油(you)室低壓(ya)油(you)路便與(yu)柱(zhu)(zhu)(zhu)塞頭部(bu)的(de)(de)(de)中孔和徑(jing)向(xiang)(xiang)孔及斜槽(cao)溝通,油(you)壓(ya)驟然下(xia)(xia)降,出油(you)閥(fa)(fa)在(zai)彈(dan)簧力(li)的(de)(de)(de)作(zuo)用下(xia)(xia)迅速關閉(bi),停止(zhi)供(gong)油(you)。此(ci)后柱(zhu)(zhu)(zhu)塞還要上(shang)(shang)(shang)行(xing)(xing),當(dang)凸輪(lun)的(de)(de)(de)凸起部(bu)分轉過去后,在(zai)彈(dan)簧的(de)(de)(de)作(zuo)用下(xia)(xia),柱(zhu)(zhu)(zhu)塞又下(xia)(xia)行(xing)(xing)。此(ci)時便開始了(le)下(xia)(xia)一個(ge)(ge)(ge)循環。柱(zhu)(zhu)(zhu)塞泵以(yi)一個(ge)(ge)(ge)柱(zhu)(zhu)(zhu)塞為原理介紹,一個(ge)(ge)(ge)柱(zhu)(zhu)(zhu)塞泵上(shang)(shang)(shang)有兩個(ge)(ge)(ge)單(dan)向(xiang)(xiang)閥(fa)(fa),并(bing)且方向(xiang)(xiang)相反,柱(zhu)(zhu)(zhu)塞向(xiang)(xiang)一個(ge)(ge)(ge)方向(xiang)(xiang)運(yun)動時缸(gang)(gang)內(nei)出現負壓(ya),這(zhe)時一個(ge)(ge)(ge)單(dan)向(xiang)(xiang)閥(fa)(fa)打開液(ye)體被(bei)(bei)吸入(ru)缸(gang)(gang)內(nei),柱(zhu)(zhu)(zhu)塞向(xiang)(xiang)另一個(ge)(ge)(ge)方向(xiang)(xiang)運(yun)動時,將(jiang)液(ye)體壓(ya)縮后另一個(ge)(ge)(ge)單(dan)向(xiang)(xiang)閥(fa)(fa)被(bei)(bei)打開,被(bei)(bei)吸入(ru)缸(gang)(gang)內(nei)的(de)(de)(de)液(ye)體被(bei)(bei)排出。這(zhe)種(zhong)工作(zuo)方式連(lian)續運(yun)動后就形成了(le)連(lian)續供(gong)油(you) 。
