廣泛應(yīng)用于鋼鐵、冶金、鋁行業(yè)、石油化工、航天、船舶制造、煤炭、水泥、電力、汽車、工程機(jī)械、食品、藥業(yè)、林業(yè)、紡織、皮革、造紙等行業(yè)領(lǐng)域

葉片泵的管理要點(diǎn)除需防干轉(zhuǎn)和過(guò)載、防吸入空氣和吸入真空度過(guò)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zui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。
3．拆裝 注意工作表面清潔，工作時(shí)油液應(yīng)很好過(guò)濾。
4. 葉片在葉槽中的間隙太大會(huì)使漏泄增加，太小則葉片不能自由伸縮，會(huì)導(dǎo)致工作失常。
5．葉片泵的軸向間隙 對(duì)ηv影響很大。
1)小型泵-0.015～0.03mm
2)中型泵-0.02～0.045mm
6．油液的溫度和粘度 一般不宜超過(guò)55℃，粘度要求在17～37mm2/s之間。粘度太大則吸油困難；粘度太小則漏泄嚴(yán)重。

一、單作用葉片泵的工作原理
泵由轉(zhuǎn)子1、定子2、葉片3、配油盤和端蓋等部件所組成。定子的內(nèi)表面是圓柱形孔。轉(zhuǎn)子和定子之間存在著偏心。葉片在轉(zhuǎn)子的槽內(nèi)可靈活滑動(dòng)，在轉(zhuǎn)子轉(zhuǎn)動(dòng)時(shí)的離心力以及通入葉片根部壓力油的作用下，葉片頂部貼緊在定子內(nèi)表面上，于是兩相鄰葉片、配油盤、定子和轉(zhuǎn)子間便形成了一個(gè)個(gè)密封的工作腔。當(dāng)轉(zhuǎn)子按逆時(shí)針?lè)较蛐D(zhuǎn)時(shí)，圖右側(cè)的葉片向外伸出，密封工作腔容積逐漸增大，產(chǎn)生真空，于是通過(guò)吸油口6和配油盤5上窗口將油吸入。而在圖的左側(cè)。葉片往里縮進(jìn)，密封腔的容積逐漸縮小，密封腔中的油液經(jīng)配油盤另一窗口和壓油口1被壓出而輸出到系統(tǒng)中去。這種泵在轉(zhuǎn)子轉(zhuǎn)一轉(zhuǎn)過(guò)程中，吸油壓油各一次，故稱單作用泵。轉(zhuǎn)子受到徑向液壓不平衡作用力，故又稱非平衡式泵，其軸承負(fù)載較大。改變定子和轉(zhuǎn)子間的偏心量，便可改變泵的排量，故這種泵都是變量泵。
二、雙作用葉片泵的工作原理
它的作用原理和單作用葉片泵相似，不同之處只在于定子表面是由兩段長(zhǎng)半徑圓弧、兩段短半徑圓弧和四段過(guò)渡曲線八個(gè)部分組成，且定子和轉(zhuǎn)子是同心的。在圖示轉(zhuǎn)子順時(shí)針?lè)较蛐D(zhuǎn)的情況下，密封工作腔的容積在左上角和右下角處逐漸增大，為吸油區(qū)，在左下角和右上角處逐漸減小，為壓油區(qū)；吸油區(qū)和壓油區(qū)之間有一段封油區(qū)把它們隔開。這種泵的轉(zhuǎn)子每轉(zhuǎn)一轉(zhuǎn)，每個(gè)密封工作腔完成吸油和壓油動(dòng)作各兩次，所以稱為雙作用葉片泵。泵的兩個(gè)吸油區(qū)和兩個(gè)壓油區(qū)是徑向?qū)ΨQ的，作用在轉(zhuǎn)子上的液壓力徑向平衡，所以又稱為平衡式葉片泵。
雙作用葉片泵的瞬時(shí)流量是脈動(dòng)的，當(dāng)葉片數(shù)為4的倍數(shù)時(shí)脈動(dòng)率小。為此，雙作用葉片泵的葉片數(shù)一般都取12或16。

力士樂(lè)齒輪泵  齒輪泵是依靠泵缸與嚙合齒輪間所形成的工作容積變化和移動(dòng)來(lái)輸送液體或使之增壓的回轉(zhuǎn)泵。由兩個(gè)齒輪、泵體與前后蓋組成兩個(gè)封閉空間，當(dāng)齒輪轉(zhuǎn)動(dòng)時(shí)，齒輪脫開側(cè)的空間的體積從小變大，形成真空，將液體吸入，齒輪嚙合側(cè)的空間的體積從大變小，而將液體擠入管路中去。吸入腔與排出腔是靠?jī)蓚€(gè)齒輪的嚙合線來(lái)隔開的。齒輪泵的排出口的壓力*取決于泵出處阻力的大小。


zui基本形式就是兩個(gè)尺寸相同的齒輪在一個(gè)緊密配合的殼體內(nèi)相互
嚙合旋轉(zhuǎn)，這個(gè)殼體的內(nèi)部類似“8”字形，兩個(gè)齒輪裝在里面，齒輪的外徑及兩側(cè)與殼體緊密配合。來(lái)自于擠出機(jī)的物料在吸入口進(jìn)入兩個(gè)齒輪中間，并充滿這一空間，隨著齒的旋轉(zhuǎn)沿殼體運(yùn)動(dòng)，zui后在兩齒嚙合時(shí)排出。
齒輪泵也叫正排量裝置，即像一個(gè)缸筒內(nèi)的活塞，當(dāng)一個(gè)齒進(jìn)入另一個(gè)齒的流體空間時(shí)，液體就被機(jī)械性地?cái)D排出來(lái)。因?yàn)橐后w是不可壓縮的，所以液體和齒就不能在同一時(shí)間占據(jù)同一空間，這樣，液體就被排除了。由于齒的不斷嚙合，這一現(xiàn)象就連續(xù)在發(fā)生，因而也就在泵的出口提供了一個(gè)連續(xù)排除量，泵每轉(zhuǎn)一轉(zhuǎn)，排出的量是一樣的。隨著驅(qū)動(dòng)軸的不間斷地旋轉(zhuǎn)，泵也就不間斷地排出流體。泵的流量直接與泵的轉(zhuǎn)速有關(guān)。


液壓站又稱液壓泵站，是獨(dú)立的液壓裝置，它按驅(qū)動(dòng)裝置（主機(jī)）要求供油，并控制油流的方 向、壓力和流量，它適用于主機(jī)與液壓裝置可分離的各種液壓機(jī)械下。 用戶購(gòu)買后只要將液壓站與 主機(jī)上的執(zhí)行機(jī)構(gòu)（油缸和油馬達(dá)）用油管相連，液壓機(jī)械即可實(shí)現(xiàn)各種規(guī)定的動(dòng)作、工作循環(huán)。 
液壓站[The hydraulic pressure stands ]液壓站是由液壓泵、驅(qū)動(dòng)用電動(dòng)機(jī)、油箱、溢流閥等構(gòu)成的液壓源裝置或包括控制閥在內(nèi)的液壓裝置。按驅(qū)動(dòng)裝置要求的流向、壓力和流量供油，適用于驅(qū)動(dòng)裝置與液壓站分離的各種機(jī)械上，將液壓站與驅(qū)動(dòng)裝置（油缸或馬達(dá)）用油管相連，液壓系統(tǒng)既可實(shí)現(xiàn)各種規(guī)定的動(dòng)作。工作原理：電機(jī)帶動(dòng)油泵工作提供壓力源，通過(guò)集成塊、液壓閥等對(duì)驅(qū)動(dòng)裝置（油缸或馬達(dá)）進(jìn)行方向、壓力、流量的調(diào)節(jié)和控制，實(shí)現(xiàn)各種規(guī)定動(dòng)作。葉片泵分為雙作用泵和單作用泵：
雙作用泵工作原理：它由定子、轉(zhuǎn)子、葉片和配油盤等組成。定子內(nèi)壁近似橢圓形。葉片安裝在轉(zhuǎn)子徑向槽內(nèi)并可沿槽滑動(dòng)，轉(zhuǎn)子與定子同心安裝。當(dāng)轉(zhuǎn)子轉(zhuǎn)動(dòng)時(shí)，葉片在離心力的作用下壓向定子內(nèi)表面，并隨定子內(nèi)表面曲線的變化而被迫在轉(zhuǎn)子槽內(nèi)往復(fù)滑動(dòng)，相鄰兩葉片間的密封工作腔就發(fā)生增大和縮小的變化。葉片由小半徑圓弧向大半徑圓弧處滑移時(shí)，密封工作腔隨之逐漸增大形成局部真空，于是油箱中油液通過(guò)配油盤上吸油腔吸入；反之將油壓出。轉(zhuǎn)子每轉(zhuǎn)一周，葉片在槽內(nèi)往復(fù)滑移2次，完成2次吸油和2次壓油，并且油壓所產(chǎn)生的徑向力是平衡的，故稱雙作用式，也稱平衡式。
