六、結構與工作原理：
DB－N＊系列(lie)單線潤滑泵(beng)主要由電動機、蝸輪蝸桿(gan)減(jian)速機構、貯油(you)(you)桶、壓油(you)(you)泵(beng)、集油(you)(you)閥、配管等部分(fen)組成(cheng)。
電動(dong)(dong)機通過(guo)聯(lian)軸器驅(qu)動(dong)(dong)蝸輪(lun)蝸桿減速(su)器轉(zhuan)動(dong)(dong)，蝸輪(lun)聯(lian)動(dong)(dong)偏心(xin)軸上的驅(qu)動(dong)(dong)輪(lun)以低速(su)旋轉(zhuan)，由(you)驅(qu)動(dong)(dong)輪(lun)帶動(dong)(dong)壓油(you)(you)泵元件的工(gong)(gong)(gong)作(zuo)(zuo)活(huo)(huo)塞(sai)(sai)作(zuo)(zuo)往(wang)復(fu)(fu)運(yun)動(dong)(dong)，吸(xi)油(you)(you)口(kou)(kou)A的閉(bi)和開(kai)是由(you)工(gong)(gong)(gong)作(zuo)(zuo)活(huo)(huo)塞(sai)(sai)控(kong)制的，在工(gong)(gong)(gong)作(zuo)(zuo)活(huo)(huo)塞(sai)(sai)同(tong)一軸線上配有控(kong)制活(huo)(huo)塞(sai)(sai)，用(yong)來(lai)控(kong)制出(chu)油(you)(you)口(kou)(kou)B，當工(gong)(gong)(gong)作(zuo)(zuo)活(huo)(huo)塞(sai)(sai)右行(xing)(xing)至(zhi)完全封住(zhu)吸(xi)油(you)(you)口(kou)(kou)后(hou)繼續(xu)右行(xing)(xing)，由(you)于(yu)液壓作(zuo)(zuo)用(yong)，推(tui)動(dong)(dong)控(kong)制活(huo)(huo)塞(sai)(sai)一同(tong)右行(xing)(xing)，行(xing)(xing)至(zhi)控(kong)制活(huo)(huo)塞(sai)(sai)上的橫(heng)向(xiang)(xiang)孔(kong)與(yu)出(chu)油(you)(you)孔(kong)接通，這(zhe)(zhe)時單向(xiang)(xiang)閥被打開(kai)，工(gong)(gong)(gong)作(zuo)(zuo)腔(qiang)中(zhong)油(you)(you)脂(zhi)(zhi)被壓出(chu)出(chu)油(you)(you)口(kou)(kou)，然后(hou)工(gong)(gong)(gong)作(zuo)(zuo)活(huo)(huo)塞(sai)(sai)左行(xing)(xing)，同(tong)時由(you)于(yu)彈簧力的作(zuo)(zuo)用(yong)，使控(kong)制活(huo)(huo)塞(sai)(sai)復(fu)(fu)位，工(gong)(gong)(gong)作(zuo)(zuo)腔(qiang)中(zhong)產生真空度，工(gong)(gong)(gong)作(zuo)(zuo)活(huo)(huo)塞(sai)(sai)左行(xing)(xing)至(zhi)打開(kai)吸(xi)油(you)(you)口(kou)(kou)后(hou)，油(you)(you)脂(zhi)(zhi)被吸(xi)入工(gong)(gong)(gong)作(zuo)(zuo)腔(qiang)。這(zhe)(zhe)樣不斷(duan)地往(wang)復(fu)(fu)運(yun)動(dong)(dong)，潤滑油(you)(you)脂(zhi)(zhi)將源(yuan)源(yuan)不斷(duan)地向(xiang)(xiang)各潤滑點供(gong)送。
兩個壓油(you)泵壓送出的(de)油(you)脂通過(guo)集油(you)閥(fa)合并成一路，且閥(fa)上裝(zhuang)有壓力(li)(li)(li)表(biao)和(he)調(diao)壓閥(fa)，可方便的(de)觀察泵的(de)出油(you)壓力(li)(li)(li)和(he)調(diao)定泵的(de)最大出油(you)壓力(li)(li)(li)。
