柱塞和柱塞套是一對(duì)精密偶件，經(jīng)配對(duì)研磨后不能互換，要求有高的精度和光潔度和好的耐磨性，其徑向間隙為0.002～0.003mm
柱塞頭部圓柱面上切有斜槽，并通過徑向孔、軸向孔與頂部相通，其目的是改變循環(huán)供油量；柱塞套上制有進(jìn)、回油孔，均與泵上體內(nèi)低壓油腔相通，柱塞套裝入泵上體后，應(yīng)用定位螺釘定位。
柱塞頭部斜槽的位置不同，改變供油量的方法也不同。
出油閥和出油閥座也是一對(duì)精密偶件，配對(duì)研磨后不能互換，其配合間隙為0.01mm 。
出油閥是一個(gè)單向閥，在彈簧壓力作用下，閥上部圓錐面與閥座嚴(yán)密配合，其作用是在停供時(shí)，將高壓油管與柱塞上端空腔隔絕，防止高壓油管內(nèi)的油倒流入噴油泵內(nèi)。
出油閥的下部呈十字?jǐn)嗝妫饶軐?dǎo)向，又能通過柴油。出油閥的錐面下有一個(gè)小的圓柱面，稱為減壓環(huán)帶，其作用是在供油終了時(shí)，使高壓油管內(nèi)的油壓迅速下降，避免噴孔處產(chǎn)生滴油現(xiàn)象。當(dāng)環(huán)帶落入閥座內(nèi)時(shí)則使上方容積很快增大，壓力迅速減小，停噴迅速。

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)，泵油過程可分為以下三個(gè)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(yùn)動(dòng)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(shí)刻不隨供油行程的變化而變化。
④ 轉(zhuǎn)動(dòng)柱塞可改變供油終了時(shí)刻，從而改變供油量。
3. 國產(chǎn)系列柱塞式噴油泵
國產(chǎn)系列柱塞泵主要有A、B、P、Z和Ⅰ、Ⅱ、Ⅲ號(hào)等系列。系列化是根據(jù)柴油機(jī)單缸功率范圍對(duì)供油量的要求不同，以柱塞行程，泵缸中心距和結(jié)構(gòu)型式為基礎(chǔ)，再分別配以不同尺寸的柱塞直徑，組成若干種在一個(gè)工作循環(huán)內(nèi)供油量不等的噴油泵，以滿足各種柴油機(jī)的需要。
國產(chǎn)系列噴油泵的工作原理和結(jié)構(gòu)型式基本相同，以A型泵為例介紹柱塞式噴油泵的構(gòu)造和工作原理。柱塞泵由四大部分組成：分泵、油量調(diào)節(jié)機(jī)構(gòu)、傳動(dòng)機(jī)構(gòu)和泵體
國產(chǎn)最新智能柱塞泵為微處理器智能控制，液晶屏顯示，可與電腦進(jìn)行通訊，具有工作壓力穩(wěn)定、脈動(dòng)小、操作方便等特點(diǎn)。廣泛用于生化、醫(yī)藥、化工、環(huán)保等行業(yè)，滿足以上行業(yè)需要連續(xù)恒壓、恒流輸送液體的要求。

液壓泵是液壓系統(tǒng)的動(dòng)力元件，其功用是給液壓系統(tǒng)提供壓力油，從能量轉(zhuǎn)換角度講，它將是原動(dòng)機(jī)（如發(fā)動(dòng)機(jī)）輸出的機(jī)械能轉(zhuǎn)換為便于輸送的液體的壓力能。液壓馬達(dá)則屬于執(zhí)行元件，它能將輸入液體的壓力能轉(zhuǎn)換為輸出軸轉(zhuǎn)動(dòng)的機(jī)械能，用來拖動(dòng)負(fù)載做功。根據(jù)結(jié)構(gòu)形式，液壓泵與液壓馬達(dá)具體可分為齒輪式、葉片式、柱塞式等類型。
1.液壓泵壓力
液壓泵工作壓力是指泵（或馬達(dá)）在實(shí)際工作時(shí)輸出（或輸入）油液的壓力，由外負(fù)載決定。
額定壓力是指在正常工作條件下，按試驗(yàn)標(biāo)準(zhǔn)規(guī)定能連續(xù)運(yùn)轉(zhuǎn)的最高壓力。其大小受壽命的限制，若超過額定壓力工作，泵（或馬達(dá)）的使用壽命將會(huì)比設(shè)計(jì)的壽命短。當(dāng)工作壓力大于額定壓力時(shí)稱超載。
