型號(hào)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(duì)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。

機(jī)床是指制造機(jī)器的機(jī)器，亦稱工作母機(jī)或工具機(jī)，習(xí)慣上簡稱機(jī)床。一般分為金屬切削機(jī)床、鍛壓機(jī)床和木工機(jī)床等。現(xiàn)代機(jī)械制造中加工機(jī)械零件的方法很多：除切削加工外，還有鑄造、鍛造、焊接、沖壓、擠壓等，但凡屬精度要求較高和表面粗糙度要求較細(xì)的零件，一般都需在機(jī)床上用切削的方法進(jìn)行終加工。機(jī)床在國民經(jīng)濟(jì)現(xiàn)代化的建設(shè)中起著重大作用。
車床是主要用車刀對(duì)旋轉(zhuǎn)的工件進(jìn)行車削加工的機(jī)床。在車床上還可用鉆頭、擴(kuò)孔鉆、鉸刀、絲錐、板牙和滾花工具等進(jìn)行相應(yīng)的加工。車床主要用于加工軸、盤、套和其他具有回轉(zhuǎn)表面的工件，是機(jī)械制造和修配工廠中使用廣的一類機(jī)床。

鍛壓機(jī)床
鍛壓機(jī)床是金屬和機(jī)械冷加工用的設(shè)備，他只改變金屬的外形狀。鍛壓機(jī)床包括卷板機(jī)，剪板機(jī)，沖床，壓力機(jī)，液壓機(jī)，油壓機(jī)，折彎機(jī)等。

液壓機(jī)是一種以液體為工作介質(zhì)，根據(jù)帕斯卡原理制成的用于傳遞能量以實(shí)現(xiàn)各種工藝的機(jī)器。液壓機(jī)一般由本機(jī)（主機(jī)）、動(dòng)力系統(tǒng)及液壓控制系統(tǒng)三部分組成。液壓機(jī)分類有閥門液壓機(jī)，液體液壓機(jī)，工程液壓機(jī)。

液壓機(jī)（又名：油壓機(jī)）液壓機(jī)是一種利用液體靜壓力來加工金屬、塑料、橡膠、木材、粉末等制品的機(jī)械。它常用于壓制工藝和壓制成形工藝，如：鍛壓、沖壓、冷擠、校直、彎曲、翻邊、薄板拉深、粉末冶金、壓裝等等。
它的原理是利用帕斯卡定律制成的利用液體壓強(qiáng)傳動(dòng)的機(jī)械，種類很多。當(dāng)然，用途也根據(jù)需要是多種多樣的。如按傳遞壓強(qiáng)的液體種類來分，有油壓機(jī)和水壓機(jī)兩大類。

液壓機(jī)是一種以液體為工作介質(zhì)，用來傳遞能量以實(shí)現(xiàn)各種工藝的機(jī)器。液壓機(jī)除用于鍛壓成形外，也可用于矯正、壓裝、打包、壓塊和壓板等。液壓機(jī)包括水壓機(jī)和油壓機(jī)。以水基液體為工作介質(zhì)的稱為水壓機(jī),以油為工作介質(zhì)的稱為油壓機(jī)。液壓機(jī)的規(guī)格一般用公稱工作力（千牛）或公稱噸位（噸）表示。鍛造用液壓機(jī)多是水壓機(jī)，噸位較高。為減小設(shè)備尺寸，大型鍛造水壓機(jī)常用較高壓強(qiáng)（35兆帕左右），有時(shí)也采用100兆帕以上的超高壓。其他用途的液壓機(jī)一般采用6～25兆帕的工作壓強(qiáng)。油壓機(jī)的噸位比水壓機(jī)低。

基本原理是油泵把液壓油輸送到集成插裝閥塊，通過各個(gè)單向閥和溢流閥把液壓油分配到油缸的上腔或者下腔，在高壓油的作用下，使油缸進(jìn)行運(yùn)動(dòng).液壓機(jī)是利用液體來傳遞壓力的設(shè)備。液體在密閉的容器中傳遞壓力時(shí)是遵循帕斯卡定律。四柱液壓機(jī)的液壓傳動(dòng)系統(tǒng)由動(dòng)力機(jī)構(gòu)、控制機(jī)構(gòu)、執(zhí)行機(jī)構(gòu)、輔助機(jī)構(gòu)和工作介質(zhì)組成。動(dòng)力機(jī)構(gòu)通常采用油泵作為動(dòng)力機(jī)構(gòu)，一般為積式油泵。為了滿足執(zhí)行機(jī)構(gòu)運(yùn)動(dòng)速度的要求，選用一個(gè)油泵或多個(gè)油泵。低壓（油壓小于2.5MP）用齒輪泵；中壓（油壓小于6.3MP）用葉片泵；高壓（油壓小于32.0MP)用柱塞泵。各種可塑性材料的壓力加工和成形，如不銹鋼板的擠壓、彎曲、拉深及金屬零件的冷壓成形，同時(shí)亦可用于粉末制品、砂輪、膠木、樹脂熱固性制品的壓制。
