葉片泵的工作原理及結構一、雙葉片泵的工作原理

1、定子(內腔型線):

1）兩段長半徑圓弧

2）兩段短半徑圓弧

3）四段過渡曲線

2、轉子:

有若干葉槽，內有葉片。旋轉時，葉片受離心力及液壓力作用下，外頂定子內壁，并在槽內往復滑動。

3、配油盤:

在定子和轉子兩側，盤上有兩對吸、排口，在定子、轉子、葉片和配油盤之間形成若干個工作空間。

葉片由短轉向長半徑時,葉片間v增大，p降低，經配油盤吸油。葉片由長向短半徑時,葉片間v減小，經配油盤的排出口排油。當葉片位于密封區時,正好將吸、排口隔開，葉片間v不變，沒有困油問題。轉子轉一周，每工作v都吸、排兩次（雙作用泵）。

二、單作用葉片泵的工作原理

定子內腔型線是圓，轉子軸與定子偏心。逆時針回轉時，工作v右半轉增大，左半轉v 減小。從兩側配油盤的吸、排口吸排油。

兩相鄰葉片轉到吸、排油口間的密封區時，所接觸定子曲線不是與轉子同心的圓弧。密封區的圓心角略大于相鄰葉片所占圓心角。

葉間工作v 先略有增大，然后略有縮小，會產生困油現象，但不太嚴重。通過在排出口邊緣開三角形卸荷槽的方法即可解決。

定子、轉子和軸承受徑向力作用，屬非卸荷式葉片泵。工作p不宜太高，q的均勻性也比雙作用差。

移動定子可改變偏心的方向及大小，可做成n恒定而q可變的雙向或單向的無級變量泵。其中用得較多的是限壓式變量葉片泵。

葉片泵轉子旋轉時，葉片在離心力和壓力油的作用下，尖部緊貼在定子內表面上。這樣兩個葉片與轉子和定子內表面所構成的工作容積，先由小到大吸油后再由大到小排油，葉片旋轉一周時，完成兩次吸油與排油。

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，圖右側的葉片向外伸出，密封工作腔容積逐漸增大，產生真空，于是通過吸油口6和配油盤5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，密封腔中的油液經配油盤另一窗口和壓油口1被壓出而輸出到系統中去。這種泵在轉子轉一轉過程中，吸油壓油各一次，故稱單作用泵。轉子受到徑向液壓不平衡作用力，故又稱非平衡式泵，其軸承負載較大。改變定子和轉子間的偏心量，便可改變泵的排量，故這種泵都是變量泵。

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半徑圓弧、兩段短半徑圓弧和四段過渡曲線八個部分組成，且定子和轉子是同心的。在圖示轉子順時針方向旋轉的情況下，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，在左下角和右上角處逐漸減小，為壓油區；吸油區和壓油區之間有一段封油區把它們隔開。這種泵的轉子每轉一轉，每個密封工作腔完成吸油和壓油動作各兩次，所以稱為雙作用葉片泵。泵的兩個吸油區和兩個壓油區是徑向對稱的，作用在轉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流量是脈動的，當葉片數為4的倍數時脈動率小。為此，雙作用葉片泵的葉片數一般都取12或16。
適合多種不同速度和粘度范圍

可提供聯軸泵可和軸向柱塞泵和內嚙合齒輪泵連接使用

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，圖右側的葉片向外伸出，密封工作腔容積逐漸增大，產生真空，于是通過吸油口6和配油盤5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，密封腔中的油液經配油盤另一窗口和壓油口1被壓出而輸出到系統中去。這種泵在轉子轉一轉過程中，吸油壓油各一次，故稱單作用泵。轉子受到徑向液壓不平衡作用力，故又稱非平衡式泵，其軸承負載較大。改變定子和轉子間的偏心量，便可改變泵的排量，故這種泵都是變量泵。

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半徑圓弧、兩段短半徑圓弧和四段過渡曲線八個部分組成，且定子和轉子是同心的。在圖示轉子順時針方向旋轉的情況下，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，在左下角和右上角處逐漸減小，為壓油區；吸油區和壓油區之間有一段封油區把它們隔開。這種泵的轉子每轉一轉，每個密封工作腔完成吸油和壓油動作各兩次，所以稱為雙作用葉片泵。泵的兩個吸油區和兩個壓油區是徑向對稱的，作用在轉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流量是脈動的，當葉片數為4的倍數時脈動率小。為此，雙作用葉片泵的葉片數一般都取12或16。
