VICKERS柱塞泵的維修與保養(yǎng)
液壓柱塞泵
威格士液壓柱塞泵靠氣壓供油的液壓油箱，在每次啟動(dòng)機(jī)器后，必須等液壓漬箱達(dá)到使用氣壓后，才能操作機(jī)械。直軸斜盤式柱塞泵分為壓力供油型的自吸油型兩種。壓力供油型液壓泵大都采用有氣壓的油箱，也有液壓泵本身帶有補(bǔ)油分泵向液壓泵進(jìn)油口提供壓力油的。自吸油型液壓泵的自吸油能力很強(qiáng)，無(wú)需外力供油。對(duì)于自吸油型柱塞泵，液壓油箱內(nèi)的油液不得低于油標(biāo)下限，要保持足夠數(shù)量的液壓油。液壓油的清潔度越高，液壓泵的使用壽命越長(zhǎng)。
威格士柱塞泵工作原理編輯
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，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，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)滑靴與斜盤相接觸，當(dāng)傳動(dòng)軸帶動(dòng)缸體旋轉(zhuǎn)時(shí)，斜盤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)配油盤分別與泵的吸、排油腔相通。變量機(jī)構(gòu)用來(lái)改變斜盤的傾角，通過(guò)調(diào)節(jié)斜盤的傾角可改變泵的排量。
威格士柱塞泵柱塞往復(fù)運(yùn)動(dòng)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(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。

柱塞泵的維護(hù)編輯
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。
