ATOS柱塞泵

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(guò)程可分為以下三個(gè)階段。 　進(jìn)油過(guò)程 　當(dāng)凸輪的凸起部分轉(zhuǎn)過(guò)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(guò)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(guò)噴油器噴入燃燒室。
