葉片泵的分類 葉片泵又分為雙作用葉片泵和單作用葉片泵。雙作用葉片泵只能作定量泵用，單作用葉片泵可作變量泵用。 雙作用葉片泵因轉(zhuǎn)子旋轉(zhuǎn)一周，葉片在轉(zhuǎn)子葉片槽內(nèi)滑動(dòng)兩次，完成兩次吸油和壓油而得名。 單作用葉片泵轉(zhuǎn)子每轉(zhuǎn)一周，吸、壓油各一次，故稱為單作用。
葉片泵的工作原理葉片泵轉(zhuǎn)子旋轉(zhuǎn)時(shí)，葉片在離心力和壓力油的作用下，尖部緊貼在定子內(nèi)表面上。這樣兩個(gè)葉片與轉(zhuǎn)子和定子內(nèi)表面所構(gòu)成的工作容積，先由小到大吸油后再由大到小排 油，葉片旋轉(zhuǎn)一周時(shí)，完成兩次吸油與排油。
葉片泵的注意事項(xiàng)葉片泵的管理要點(diǎn)除需防干轉(zhuǎn)和過載、防吸入空氣和吸入真空度過大外，還應(yīng)注意： 1．泵轉(zhuǎn)向改變，則其吸排方向也改變?nèi)~片泵都有規(guī)定的轉(zhuǎn)向，不允許反。因?yàn)檗D(zhuǎn) 子葉槽有傾斜，葉片有倒角，葉片底部與排油腔通，配油盤上的節(jié)流槽和吸、排口是按既定轉(zhuǎn)向設(shè)計(jì)。可逆轉(zhuǎn)的葉片泵必須專門設(shè)計(jì)。 2．葉片泵裝配 配油盤與定子用定位銷正確定位，葉片、轉(zhuǎn)子、配油盤都不得裝反， 定子內(nèi)表面吸入?yún)^(qū)部分易磨損，必要時(shí)可將其翻轉(zhuǎn)安裝，以使原吸入?yún)^(qū)變?yōu)榕懦鰠^(qū)而繼續(xù)使用。
型號 PV7 的液壓泵是變量葉片泵。
主要由泵體、轉(zhuǎn)子、葉片、定子環(huán)、壓力控制器和調(diào)節(jié)螺栓組成。圓形的定子環(huán)夾持在小調(diào)節(jié)活塞和大調(diào)節(jié)活塞之間。此環(huán)的第三個(gè)接觸點(diǎn)是高度調(diào)節(jié)螺栓。被驅(qū)動(dòng)的轉(zhuǎn)子在定子環(huán)內(nèi)轉(zhuǎn)動(dòng)。轉(zhuǎn)子槽內(nèi)的葉片由于離心力的作用壓在定子環(huán)上。
力士樂REXROTH葉片泵吸油和排油過程
用來傳遞油液的腔由葉片、轉(zhuǎn)子、定子環(huán)和配油盤形成。
為了在投入使用時(shí)確保泵的運(yùn)行功能，定子環(huán)由大調(diào)節(jié)活塞后面的彈簧壓在其偏心位置 (排油位置)。
當(dāng)轉(zhuǎn)子轉(zhuǎn)動(dòng)時(shí)，油腔的容積增大，并且通過吸油通道吸油。當(dāng)油腔達(dá)到大容積時(shí)，它脫離吸油側(cè)。轉(zhuǎn)子繼續(xù)轉(zhuǎn)動(dòng)，此腔和壓油側(cè)接通，并使其容積減小，通過壓油通道壓油到系統(tǒng)。
類型 PV7...A 液壓泵是直動(dòng)式葉片泵，其排量體積可調(diào)。
基本上由殼體，蓋板，轉(zhuǎn)子，葉片，定子環(huán)，壓縮彈簧，調(diào)整螺釘和控制板組成。為限制大流量，該泵配有調(diào)節(jié)螺釘。驅(qū)動(dòng)轉(zhuǎn)子在定子環(huán)中旋轉(zhuǎn)。轉(zhuǎn)子中導(dǎo)入的葉片在離心力的作用下貼緊定子環(huán)的內(nèi)跑合面。
吸油和排油過程
運(yùn)輸流體所需的腔室由葉片，轉(zhuǎn)子，定子環(huán)，控制板和蓋板組成。
轉(zhuǎn)子旋轉(zhuǎn)時(shí)室體積增加，腔室通過吸油通道填充流體。達(dá)到大室體積后，腔室從吸油側(cè)分離。
隨著轉(zhuǎn)子繼續(xù)旋轉(zhuǎn)，高壓流體側(cè)的連接打開，腔室縮小并迫使流體通過壓力油口進(jìn)入系統(tǒng)。
壓力控制
定子環(huán)由彈簧固定在其初始的偏心位置。系統(tǒng)中所需的大工作壓力是在調(diào)節(jié)螺釘處通過彈簧設(shè)定。增大的壓力是由于對抗彈簧力的工作阻力作用于定子
環(huán)內(nèi)跑合面的壓力側(cè)而產(chǎn)生的。
達(dá)到相關(guān)壓力（由設(shè)定的彈簧力決定）后，定子環(huán)朝零位置的方向移出其偏心位置。流量自我調(diào)節(jié)至當(dāng)時(shí)所需的值。當(dāng)達(dá)到
彈簧處設(shè)置的大設(shè)定壓力時(shí)，泵會(huì)將流量調(diào)回至幾乎為零。工作壓力得到保持，且僅更換泄露流體。流體的損失和加熱從而降至低水平。

液壓泵是液壓系統(tǒng)的動(dòng)力元件，是靠發(fā)動(dòng)機(jī)或電動(dòng)機(jī)驅(qū)動(dòng)，從液壓油箱中吸入油液，形成壓力油排出，送到執(zhí)行元件的一種元件。液壓泵按結(jié)構(gòu)分為齒輪泵、柱塞泵、葉片泵和螺桿泵
液壓泵為液壓傳動(dòng)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(dòng)力機(jī)（如電動(dòng)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(jià)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(jià)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(shí)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。
液壓系統(tǒng)的組成及其作用
一個(gè)完整的液壓系統(tǒng)由五個(gè)部分組成，即動(dòng)力元件、執(zhí)行元件、控制元件、輔助元件(附件)和液壓油。
動(dòng)力元件的作用是將原動(dòng)機(jī)的機(jī)械能轉(zhuǎn)換成液體的壓力能，指液壓系統(tǒng)中的油泵，它向整個(gè)液壓系統(tǒng)提供動(dòng)力。液壓泵的結(jié)構(gòu)形式一般有齒輪泵、葉片泵和柱塞泵。
執(zhí)行元件(如液壓缸和液壓馬達(dá))的作用是將液體的壓力能轉(zhuǎn)換為機(jī)械能，驅(qū)動(dòng)負(fù)載作直線往復(fù)運(yùn)動(dòng)或回轉(zhuǎn)運(yùn)動(dòng)。
控制元件(即各種液壓閥)在液壓系統(tǒng)中控制和調(diào)節(jié)液體的壓力、流量和方向。根據(jù)控制功能的不同，液壓閥可分為壓力控制閥、流量控制閥和方向控制閥。壓力控制閥又分為益流閥(安全閥)、誠壓閥、順序閥、壓力繼電器等;流量控制閥包括節(jié)流閥、調(diào)整閥、分流集流閥等，方向控制閥包括單向閥、液控單向閥、梭閥、換向閥等。根據(jù)控制方式不同，液壓閥可分為開關(guān)式控制閥、定值控制閥和比例控制閥。
輔助元件包括油箱、濾油器、油管及管接頭、密封圈、快換接頭、高壓球閥、膠管總成、測壓接頭、壓力表、油位油溫計(jì)等。
液壓油是液壓系統(tǒng)中傳遞能量的工作介質(zhì)，有各種礦物油、乳化液和合成型液壓油等幾大類。

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。
2.轉(zhuǎn)速
工作轉(zhuǎn)速是指泵（或馬達(dá)）在工作時(shí)的實(shí)際轉(zhuǎn)動(dòng)速度。
額定轉(zhuǎn)速是指在額定壓力下，能連續(xù)長時(shí)間正常運(yùn)轉(zhuǎn)的高轉(zhuǎn)速。若泵超過額定轉(zhuǎn)速工作將會(huì)造成吸油不足，產(chǎn)生振動(dòng)和大的噪聲，零件會(huì)遭受氣蝕損傷，壽命降低。
低穩(wěn)定轉(zhuǎn)速是指馬達(dá)正常運(yùn)轉(zhuǎn)所允許的低轉(zhuǎn)速。在此轉(zhuǎn)速下，馬達(dá)不出現(xiàn)爬行現(xiàn)象。
3.排量、流量
排量是指泵（或馬達(dá)）每轉(zhuǎn)一周，由密封容腔幾何尺寸變化而得的排出（或輸入）液體的體積，常用單位是ml/r（毫升/轉(zhuǎn)）。排量可以通過調(diào)節(jié)發(fā)生變化的成為變量泵（或變量馬達(dá)），排量不能變化的成為定量泵（或定量馬達(dá)）。
實(shí)際流量是指泵（或馬達(dá)）工作時(shí)出口處（或進(jìn)口處）的流量。由于泵本身存在內(nèi)泄漏，其實(shí)際流量小于理論流量。由于馬達(dá)本身也存在內(nèi)泄漏，要實(shí)現(xiàn)指定轉(zhuǎn)速，為補(bǔ)償泄漏量，其輸入實(shí)際流量必須大于理論流量。
4.效率
容積效率，對液壓泵是指其實(shí)際流量與理論流量的比值。對液壓馬達(dá)是指其理論流量與實(shí)際流量的比值。
機(jī)械效率，對液壓泵是指其理論轉(zhuǎn)矩與實(shí)際輸入轉(zhuǎn)矩的比值。對液壓馬達(dá)其實(shí)際輸出的轉(zhuǎn)矩為理論轉(zhuǎn)矩克服摩擦力后的轉(zhuǎn)矩，因此其機(jī)械效率為實(shí)際輸出轉(zhuǎn)矩與理論轉(zhuǎn)矩的比值。
總效率是指泵（或馬達(dá)）的輸出功率與輸入功率的比值。總效率等于容積效率與機(jī)械效率的乘積。
