單作用葉片泵

單作用葉片泵的定義:葉片在離力和壓力油的作用下，尖部緊貼在定子內(nèi)表面上。通過改變兩個葉片與轉子和定子內(nèi)表面所構成的工作容積大小變化，完成吸油排油過程，且葉片旋轉一周，完成一次吸油與排油的葉片泵。

特點: 

1.泵每轉一轉，每個密封腔吸油壓油一次

2.轉子上受液壓不平衡力，為非平衡式泵

3.改變偏心距大小，可改變排量，為變量泵

 

單作用葉片泵的工作原理

泵由轉子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。轉子和定子之間存在著偏心。葉片在轉子的槽內(nèi)可靈活滑動，在轉子轉動時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、定子和轉子間便形成了一個個密封的工作腔。

當轉子按逆時針方向旋轉時，右側的葉片向外伸出，密封工作腔容積逐漸加大，產(chǎn)生真空，于是通過吸油口和配油盤上窗口將油吸入。而在圖的左側。葉片往里縮進，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。

 

工作過程分析

單作用葉片泵的定子具有圓柱形內(nèi)表面，定子和轉子間有偏心距。若有Z個葉片，則定子圓周被分成Z部分。這里用r表示轉子外圓半徑，用R表示定子內(nèi)表面半徑。在垂直于轉子軸的平面內(nèi)，s1表示密封工作空間的較小值(即葉片滑出的距離較短)，它在半徑方向的尺寸為[(R-e)-r]; S2表示密封工作空間的較大值(即葉片滑出的距離較長)，它在半徑方向的尺寸為[(R e)-r]。

 

利用等效法推導計算公式

從單作用葉片泵的工作過程可以看出，在離心力的作用下，葉片的頂端一直與定子內(nèi)壁接觸，由于定子內(nèi)表面半徑為R，則其周長為2πR，而葉片的行程為2e,故在轉子轉動一周的過程中，任意相鄰的兩個葉片所圍成的工作腔，在半徑方向上的變化幅度都等于2e.在計算單作用葉片泵的排量時，可將其工作過程等效視為:葉片的頂端先集中在長度為2πR 直線段上，然后同時沿著定子圓周的法線方向移動2e的距離。則密封容積幾何尺寸的變化量可以等效長方體體積。

機床是指制造機器的機器，亦稱工作母機或工具機，習慣上簡稱機床。一般分為金屬切削機床、鍛壓機床和木工機床等�，F(xiàn)代機械制造中加工機械零件的方法很多：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的零件，一般都需在機床上用切削的方法進行終加工。機床在國民經(jīng)濟現(xiàn)代化的建設中起著重大作用。

車床是主要用車刀對旋轉的工件進行車削加工的機床。在車床上還可用鉆頭、擴孔鉆、鉸刀、絲錐、板牙和滾花工具等進行相應的加工。車床主要用于加工軸、盤、套和其他具有回轉表面的工件，是機械制造和修配工廠中使用廣的一類機床。

 

鍛壓機床

鍛壓機床是金屬和機械冷加工用的設備，他只改變金屬的外形狀。鍛壓機床包括卷板機，剪板機，沖床，壓力機，液壓機，油壓機，折彎機等。

 

液壓機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現(xiàn)各種工藝的機器。液壓機一般由本機（主機）、動力系統(tǒng)及液壓控制系統(tǒng)三部分組成。液壓機分類有閥門液壓機，液體液壓機，工程液壓機。

 

液壓機（又名：油壓機）液壓機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傳動的機械，種類很多。當然，用途也根據(jù)需要是多種多樣的。如按傳遞壓強的液體種類來分，有油壓機和水壓機兩大類。

 

液壓機是一種以液體為工作介質(zhì)，用來傳遞能量以實現(xiàn)各種工藝的機器。液壓機除用于鍛壓成形外，也可用于矯正、壓裝、打包、壓塊和壓板等。液壓機包括水壓機和油壓機。以水基液體為工作介質(zhì)的稱為水壓機,以油為工作介質(zhì)的稱為油壓機。液壓機的規(guī)格一般用公稱工作力（千牛）或公稱噸位（噸）表示。鍛造用液壓機多是水壓機，噸位較高。為減小設備尺寸，大型鍛造水壓機常用較高壓強（35兆帕左右），有時也采用 100兆帕以上的非常高壓。其他用途的液壓機一般采用 6～25兆帕的工作壓強。油壓機的噸位比水壓機低。

 

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，使油缸進行運動.液壓機是 利用液體來傳遞壓力的設備。液體在密閉的容器中傳遞壓力時是遵循帕斯卡定律。四柱液壓機的液壓傳動系統(tǒng)由動力機構、控制機構、執(zhí)行機構、輔助機構和工作介質(zhì)組成。動力機構通常采用油泵作為動力機構，一般為積式油泵。為了滿足執(zhí)行機構運動速度的要求， 選用一個油泵或多個油泵。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，同時亦可用于粉末制品、砂輪、膠木、樹脂熱固性制品的壓制。
