柱塞泵一般分為單柱塞泵、臥式柱塞泵、軸向柱塞泵和徑向柱塞泵。
單柱塞泵
結(jié)構(gòu)組成主要有偏心輪、柱塞、彈簧、缸體、兩個單向閥。柱塞與缸體孔之間形成密閉容積。偏心輪旋轉(zhuǎn)一轉(zhuǎn)，柱塞上下往復(fù)運(yùn)動一次，向下運(yùn)動吸油，向上運(yùn)動排油。泵每轉(zhuǎn)一轉(zhuǎn)排出的油液體積稱為排量，排量只與泵的結(jié)構(gòu)參數(shù)有關(guān)。
臥式柱塞泵
臥式柱塞泵是由幾個柱塞（一般為3個或6個）并列安裝，用1根曲軸通過連桿滑塊或由偏心軸直接推動柱塞做往復(fù)運(yùn)動，實(shí)現(xiàn)吸、排液體的液壓泵。它們也都采用閥式配流裝置，而且大多為定量泵。煤礦液壓支架系統(tǒng)中的乳化液泵一般都是臥式柱塞泵。
乳化液泵用于采煤工作面，為液壓支架提供乳化液，工作原理靠曲軸的旋轉(zhuǎn)帶動活塞做往復(fù)運(yùn)動，實(shí)現(xiàn)吸液和排液。
軸向式
軸向柱塞泵（英文名：Piston pump）是活塞或柱塞的往復(fù)運(yùn)動方向與缸體中心軸平行的柱塞泵。軸向柱塞泵利用與傳動軸平行的柱塞在柱塞孔內(nèi)往復(fù)運(yùn)動所產(chǎn)生的容積變化來進(jìn)行工作的。由于柱塞和柱塞孔都是圓形零件，加工時可以達(dá)到很高的精度配合，因此容積效率高
直軸斜盤式
直軸斜盤式柱塞泵分為壓力供油型和自吸油型兩種。壓力供油型液壓泵大都是采用有氣壓的油箱，靠氣壓供油的液壓油箱，在每次啟動機(jī)器之后，必須等液壓漬箱達(dá)到使用氣壓后，才能操作機(jī)械。如液壓油箱的氣壓不足時就啟動機(jī)器，會對液壓泵內(nèi)的與滑靴造成拉脫現(xiàn)象，出會造成泵體內(nèi)回程板與壓板的非正常磨損。
徑向式
徑向柱塞泵可分為閥配流與軸配流兩大類。閥配流徑向柱塞泵存在故障率高、效率

液壓泵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(jī)（如電動機(jī)和內(nèi)燃機(jī)等）的機(jī)械能轉(zhuǎn)換成液體的壓力能。影響液壓泵的使用壽命因素很多，除了泵自身設(shè)計(jì)、制造因素外和一些與泵使用相關(guān)元（如聯(lián)軸器、濾油器等）的選用、試車運(yùn)行過程中的操作等也有關(guān)。
常用液壓泵的種類：
1、按流量是否可調(diào)節(jié)可分為：變量泵和定量泵。輸出流量可以根據(jù)需要來調(diào)節(jié)的稱為變量泵，流量不能調(diào)節(jié)的稱為定量泵。
2、按液壓系統(tǒng)中常用的泵結(jié)構(gòu)分為：齒輪泵、葉片泵和柱塞泵3種。
齒輪泵：體積較小，結(jié)構(gòu)較簡單，對油的清潔度要求不嚴(yán)，價格較便宜；但泵軸受不平衡力，磨損嚴(yán)重，泄漏較大。
葉片泵：分為雙作用葉片泵和單作用葉片泵。這種泵流量均勻、運(yùn)轉(zhuǎn)平穩(wěn)、噪音小、作壓力和容積效率比齒輪泵高、結(jié)構(gòu)比齒輪泵復(fù)雜。

柱塞泵：容積效率高、泄漏小、可在高壓下工作、大多用於大功率液壓系統(tǒng)；但結(jié)構(gòu)復(fù)雜，材料和加工精度要求高、價格貴、對油的清潔度要求高。
一般在齒輪泵和葉片泵不能滿足要求時才用柱塞泵。還有一些其他形式的液壓泵，如螺桿泵等，但應(yīng)用不如上述3種普遍。
液壓泵特點(diǎn)
鋁合金制造、強(qiáng)度高、耐腐蝕、重量輕、適合各種環(huán)境下作業(yè)。
雙速特性減少了打壓次數(shù)，在低壓室快速處于負(fù)載用功狀態(tài)，立刻轉(zhuǎn)換成高壓，縮短每次作業(yè)周期。
配有壓力調(diào)節(jié)閥，可調(diào)節(jié)控制及設(shè)定工作壓力。

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(yùn)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(yùn)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。
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號等系列。系列化是根據(jù)柴油機(jī)單缸功率范圍對供油量的要求不同，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。
