PVH098柱塞泵型號PVH098R01AJ30A25000000100100010A
【簡單介紹】
【詳細(xì)說明】
威格士vickers當(dāng)凸輪的凸起部分轉(zhuǎn)過去后,在彈簧力的作用下,柱塞向下運動,柱塞上部空間(稱為泵油室)產(chǎn)生真空度,當(dāng)柱塞上端面把柱塞套上的進油孔打開后,充滿在油泵上體油道內(nèi)的柴油經(jīng)油孔進入泵油室,柱塞運動到下止點,進油結(jié)束。供油過程
威格士vickers當(dāng)凸輪軸轉(zhuǎn)到凸輪的凸起部分頂起滾輪體時,柱塞彈簧被壓縮,柱塞向上運動,燃油受壓,一部分燃油經(jīng)油孔流回噴油泵上體油腔。當(dāng)柱塞頂面遮住套筒上進油孔的上緣時,由于柱塞和套筒的配合間隙很?。?.0015-0.0025mm)使柱塞頂部的泵油室成為一個密封油腔,柱塞繼續(xù)上升,泵油室內(nèi)的油壓迅速升高,泵油壓力>出油閥彈簧力+高壓油管剩余壓力時,推開出油閥,高壓柴油經(jīng)出油閥進入高壓油管,通過噴油器噴入燃燒室?;赜瓦^程
威格士vickers柱塞向上供油,當(dāng)上行到柱塞上的斜槽(停供邊)與套筒上的回油孔相通時,泵油室低壓油路便與柱塞頭部的中孔和徑向孔及斜槽溝通,油壓驟然下降,出油閥在彈簧力的作用下迅速關(guān)閉,停止供油。此后柱塞還要上行,當(dāng)凸輪的凸起部分轉(zhuǎn)過去后,在彈簧的作用下,柱塞又下行。此時便開始了下一個循環(huán)。結(jié)論:通過上述討論,得出下列結(jié)論
① 威格士vickers柱塞往復(fù)運動總行程L是不變的,由凸輪的升程決定。
② 威格士vickers柱塞每循環(huán)的供油量大小取決于供油行程,供油行程不受凸輪軸控制是可變的。
③ 供油開始時刻不隨供油行程的變化而變化。
④ 轉(zhuǎn)動柱塞可改變供油終了時刻,從而改變供油量。
