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。
為了在投入使用時確保泵的運行功能，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)動時，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，它脫離吸油側(cè)。轉(zhuǎn)子繼續(xù)轉(zhuǎn)動，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)時所需的值。當(dāng)達(dá)到
彈簧處設(shè)置的大設(shè)定壓力時，泵會將流量調(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。

在應(yīng)用的各種液壓設(shè)備中，液壓泵是關(guān)鍵性的元件，它們的性能和壽命在很大程度上決定著整個液壓系統(tǒng)的工作能力，隨著時代的發(fā)展和技術(shù)的進(jìn)步，液壓泵性能越 來越完善，在各種工業(yè)設(shè)備、行走機(jī)構(gòu)以及船舶和飛機(jī)上都得到了廣泛應(yīng)用。因此對于葉片泵相關(guān)知識的學(xué)習(xí)和認(rèn)識十分必要，特別是對于從事液壓相關(guān)方面工作的人更顯得尤為重要。
液壓泵作為現(xiàn)代液壓設(shè)備中的主要動力元件，它決定著整個液壓系統(tǒng)的工 作能力。在液壓系統(tǒng)中，液壓泵的功能主要是將電動機(jī)及內(nèi)燃機(jī)等原動機(jī)的機(jī)械能轉(zhuǎn)換 成液體的壓力能，向系統(tǒng)提供壓力油并驅(qū)動系統(tǒng)工作。 
在液壓傳動與控制中使用最多 的液壓泵主要有齒輪式、葉片式和柱塞式三大類型。其中葉片泵是在近代液壓技術(shù)發(fā)展早期實用的一種液壓泵。 
葉片泵與齒輪式、柱塞式相比，葉片泵具有尺寸小、重 量輕、流量均勻、噪聲低等突出優(yōu)點。在各類液壓泵中，葉片泵輸出單位液壓功率所需 重量幾乎是最輕的，加之結(jié)構(gòu)簡單，價格比柱塞泵低，可以和齒輪泵競爭。 
定量葉片泵為雙作用葉片泵，是現(xiàn)今已經(jīng)發(fā)展成熟，并在工業(yè)領(lǐng)域得到應(yīng)用的一種液壓泵，雙作用葉片泵是一般不能變量的，且徑向力平衡的,因此工作情況較其它泵良好，被應(yīng)用于液壓系統(tǒng)領(lǐng)域，成為液壓工業(yè)上不可或缺的關(guān)鍵性元件。
液壓葉片泵的發(fā)展史 液壓葉片泵的發(fā)展史即為葉片泵從誕生到發(fā)展的歷史，作為液壓系統(tǒng)的關(guān)鍵性動力元件，它隨著液壓系統(tǒng)的誕生而誕生，隨著液壓技術(shù)的發(fā)展而發(fā)展，并不斷完善以適應(yīng)新的液壓系統(tǒng)的性能要求。 

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，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，完成兩次吸油與排油。
 
葉片泵的注意事項葉片泵的管理要點除需防干轉(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。因為轉(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。可逆轉(zhuǎn)的葉片泵必須專門設(shè)計。 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)部分最易磨損，必要時可將其翻轉(zhuǎn)安裝，以使原吸入?yún)^(qū)變?yōu)榕懦鰠^(qū)而繼續(xù)使用。

單作用葉片泵的工作原理
單作用葉片泵構(gòu)造 基本結(jié)構(gòu)：定子、轉(zhuǎn)子、葉片、配油盤（吸、排口）、殼體（吸、排接管）、前、后 蓋板。 定子型線是圓，轉(zhuǎn)子也是園，二者存在偏心距。 片間工作空間：葉片、定子內(nèi)表面、轉(zhuǎn)子外表面、配油盤或蓋板圍成。
