柱塞泵柱塞往復運動總行程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。供油開始時刻不隨供油行程的變化而變化。轉(zhuǎn)動柱塞可改變供油終了時刻，從而改變供油量。柱塞泵工作時，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、下往復運動，從而完成泵油任務，泵油過程可分為以下兩個階段。

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^和柱塞為往復運動。當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；當柱塞向前死點移動時，泵腔內(nèi)壓力增大，此時吸入閥關閉，排出閥打開，液體被擠出液缸，達到了吸入和排出的目的。

濾油器的選用
一般粒徑在10μm以下的污染物對泵的影響不太明顯，而大于10μm、特別是在40μm以上時對泵的使用壽命就有明顯影響。液壓油中固體污染顆粒極易使泵內(nèi)相對運動零件表面磨損加劇，為此需要安裝濾油器降低油的污染程度。過濾精度要求：軸向柱塞泵10～15μm，葉片泵為25μm，齒輪泵為40μm。泵的污染磨損可以控制在允許范圍之內(nèi)。高精度濾油器使用日益廣泛，可大大延長液壓泵的使用壽命。
液壓泵原理
是為液壓傳動提供加壓液體的一種液壓元件，是泵的一種。它的功能是把動力機(如電動機和內(nèi)燃機等)的機械能轉(zhuǎn)換成液體的壓力能。圖中為單柱塞泵的工作原理。凸輪由電動機帶動旋轉(zhuǎn)。當凸輪推動柱塞向上運動時，柱塞和缸體形成的密封體積減小，油液從密封體積中擠出，經(jīng)單向閥排到需要的地方去。當凸輪旋轉(zhuǎn)至曲線的下降部位時，彈簧迫使柱塞向下，形成一定真空度，油 箱中的油液在大氣壓力的作用下進入密封容積。凸 輪使柱塞不斷地升降，密封容積周期性地減小和增 大，泵就不斷吸油和排油。
