VICKERS威格士PVH柱塞泵價(jià)格優(yōu)現(xiàn)貨庫(kù)存處理
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(kāi)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(guò)程可分為以下三個(gè)階段。
1、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(chēng)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(kāi)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。
2、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(kāi)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。
3、回油過(guò)程
威格士柱塞向上供油，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(guò)去后，在彈簧的作用下，柱塞又下行。此時(shí)便開(kāi)始了下一個(gè)循環(huán)。
威格士柱塞泵是往復(fù)泵的一種，屬于體積泵，其柱塞靠泵軸的偏心轉(zhuǎn)動(dòng)驅(qū)動(dòng)，往復(fù)運(yùn)動(dòng)，其吸入和排出閥都是單向閥。當(dāng)柱塞外拉時(shí)，工作室內(nèi)壓力降低，出口閥關(guān)閉，低于進(jìn)口壓力時(shí)，進(jìn)口閥打開(kāi)，液體進(jìn)入；柱塞內(nèi)推時(shí)，工作室壓力升高，進(jìn)口閥關(guān)閉，高于出口壓力時(shí)，出口閥打開(kāi)，液體排出。帶滑靴結(jié)構(gòu)的軸向柱塞泵是目前使用zui廣泛的軸向柱塞泵，安放在缸體中的柱塞通過(guò)滑靴與斜盤(pán)相接觸，當(dāng)傳動(dòng)軸帶動(dòng)缸體旋轉(zhuǎn)時(shí)，斜盤(pán)將柱塞從缸體中拉出或推回，完成吸排油過(guò)程。柱塞與缸孔組成的工作容腔中的油液通過(guò)配油盤(pán)分別與泵的吸、排油腔相通。變量機(jī)構(gòu)用來(lái)改變斜盤(pán)的傾角，通過(guò)調(diào)節(jié)斜盤(pán)的傾角可改變泵的排量。
