美國原廠出售VICKERS柱塞泵 威格士柱塞泵,，是由電動機提供泵的動力，經(jīng)鼓型齒聯(lián)軸器帶動減速機轉(zhuǎn)動,。由減速機減速帶動曲軸旋轉(zhuǎn),。通過曲柄連桿機構(gòu)，將旋轉(zhuǎn)運動轉(zhuǎn)變?yōu)槭诸^和柱塞為往復(fù)運動,。當(dāng)柱塞向后死點移動時,，泵容積腔逐步增大，泵腔內(nèi)壓力降低,，當(dāng)泵腔壓力低于進口壓力時,，吸入閥在進口端壓力作用下開啟，液體被吸入,；當(dāng)柱塞向前死點移動時,，泵腔內(nèi)壓力增大，此時吸入閥關(guān)閉,，排出閥打開,，液體被擠出液缸，達到了吸入和排出的目的,。
美國原廠出售VICKERS柱塞泵 威格士柱塞泵是活塞或柱塞的往復(fù)運動方向與缸體中心軸平行的柱塞泵,。軸向柱塞泵是利用與傳動軸平行的柱塞在柱塞孔內(nèi)往復(fù)運動所產(chǎn)生的容積變化來進行工作的,。由于柱塞和柱塞孔都是圓形零件，加工時可以達到很高的精度配合,，因此容積效率高,，運轉(zhuǎn)平穩(wěn)，流量均勻性好,，噪聲低，工作壓力高等優(yōu)點,，但對液壓油的污染較敏感,，結(jié)構(gòu)較復(fù)雜，造價較高,。
威格士柱塞泵工作階段
工作時,，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)運動,，從而完成泵油任務(wù)，泵油過程可分為以下三個階段,。
結(jié)論：通過上述討論,，得出下列結(jié)論
① 柱塞往復(fù)運動總行程L是不變的，由凸輪的升程決定,。
② 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
