概述
威格士柱塞泵柱塞往復(fù)運(yùn)動(dòng)總行程L是不變的,由凸輪的升程決定。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。供油開始時(shí)刻不隨供油行程的變化而變化。轉(zhuǎn)動(dòng)柱塞可改變供油終了時(shí)刻,從而改變供油量。柱塞泵工作時(shí),在噴油泵凸輪軸上的凸輪與柱塞彈簧的作用下,迫使柱塞作上、下往復(fù)運(yùn)動(dòng),從而完成泵油任務(wù),泵油過程可分為以下三個(gè)階段。
進(jìn)油過程
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(yùn)動(dòng),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(jìn)油孔打開后,充滿在油泵上體油道內(nèi)的柴油經(jīng)油孔進(jìn)入泵油室,柱塞運(yùn)動(dòng)到下止點(diǎn),進(jìn)油結(jié)束。
供油過程
當(dāng)凸輪軸轉(zhuǎn)到凸輪的凸起部分頂起滾輪體時(shí),柱塞彈簧被壓縮,柱塞向上運(yùn)動(dòng),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(jìn)油孔的上緣時(shí),由于柱塞和套筒的配合間隙很小(0.0015-0.0025mm)使柱塞頂部的泵油室成為一個(gè)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(shí),推開出油閥,高壓柴油經(jīng)出油閥進(jìn)入高壓油管,通過噴油器噴入燃燒室。
回油過程
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(shí),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(shí)便開始了下一個(gè)循環(huán)。
柱塞泵以一個(gè)柱塞為原理介紹,一個(gè)柱塞泵上有兩個(gè)單向閥,并且方向相反,柱塞向一個(gè)方向運(yùn)動(dòng)時(shí)缸內(nèi)出現(xiàn)負(fù)壓,這時(shí)一個(gè)單向閥打開液體被吸入缸內(nèi),柱塞向另一個(gè)方向運(yùn)動(dòng)時(shí),將液體壓縮后另一個(gè)單向閥被打開,被吸入缸內(nèi)的液體被排出。這種工作方式連續(xù)運(yùn)動(dòng)后就形成了連續(xù)供油 。
柱塞泵的維護(hù)
威格士斜盤式軸向柱塞泵一般采用缸體轉(zhuǎn)動(dòng)、端面配流的形式。缸體端面上鑲有一塊由雙金屬板與鋼配油盤組成的摩擦副,而且大多數(shù)是采用平面配流的方法,所以維修比較方便。配油盤是軸向柱塞泵的關(guān)鍵部件之一,泵工作時(shí),一方面工作腔的高壓油把缸體推向配油盤,另一方面配油盤和缸體間的油膜壓力形成對(duì)缸體的液壓反推力使缸體背離配油盤。缸體對(duì)配油盤的設(shè)計(jì)液壓壓緊力Fn略大于配油盤對(duì)缸體的液壓反推力Ff,即Fn/Ff=1.05~1.1,使泵工作正常并保持較高的容積效率。 實(shí)際上,由于油液的污染,往往使配油盤與缸體之間產(chǎn)生輕微磨損。
