葉片泵-不銹鋼葉片泵-KAYSEN泵業(yè)
GERMANY KAYSEN PUMP CO .,LTD
葉片泵，是轉子槽內的葉片與泵殼(定子環(huán))相接觸，將吸入的液體由進油側壓向排油側的泵。
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，完成一次吸油與排油。
一、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(tǒng)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。
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(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(qū)和兩個壓油區(qū)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。
主要特點：
葉片泵的管理要點除需防干轉和過載、防吸入空氣和吸入真空度過大外，還應注意：
●泵轉向改變，則其吸排方向也改變葉片泵都有規(guī)定的轉向，不允許反。因為轉子葉槽有傾斜，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、排口是按既定轉向設計?？赡孓D的葉片泵必須專門設計。
●葉片泵裝配 配油盤與定子用定位銷正確定位，葉片、轉子、配油盤都不得裝反，定子內表面吸入區(qū)部分最易磨損，必要時可將其翻轉安裝，以使原吸入區(qū)變?yōu)榕懦鰠^(qū)而繼續(xù)使用。
●拆裝 注意工作表面清潔，工作時油液應很好過濾。
● 葉片在葉槽中的間隙太大會使漏泄增加，太小則葉片不能自由伸縮，會導致工作失常。
●葉片泵的軸向間隙 對ηv影響很大。
●小型泵-0.015～0.03mm
●中型泵-0.02～0.045mm
●油液的溫度和粘度 一般不宜超過55℃，粘度要求在17～37mm2/s之間。粘度太大則吸油困難；粘度太小則漏泄嚴重。

Vortex pump
Vane pump
The vane pump is a pump in which the vane in the rotor groove is in contact with the pump casing (stator ring), and the sucked liquid is pressed from the oil inlet side to the drain side.
When the vane pump rotor rotates, the vane is pressed against the inner surface of the stator under the action of centrifugal force and pressure oil. The working volume formed by the two blades and the inner surface of the rotor and the stator is firstly drained from small to large and then drained from large to small. When the blade rotates for one week, the oil absorption and the oil discharge are completed.
First, the working principle of single-acting vane pump
The pump consists of rotor 1, stator 2, vane 3, oil distribution plate and end cover. The inner surface of the stator is a cylindrical hole. There is an eccentricity between the rotor and the stator. The blade can flexibly slide in the groove of the rotor. Under the action of the centrifugal force of the rotor rotating and the pressure oil flowing into the blade root, the blade top is closely attached to the inner surface of the stator, so that two adjacent blades, the oil distribution plate, the stator and the rotor A sealed working chamber is formed between the two. When the rotor rotates in the counterclockwise direction, the blades on the right side of the figure protrude outward, and the volume of the sealed working chamber gradually increases to generate a vacuum, so that the oil is sucked through the suction port 6 and the window on the oil distribution plate 5. And on the left side of the figure. The blade is retracted inward, the volume of the sealed cavity is gradually reduced, and the oil in the sealed cavity is pressed out through the other window of the oil distribution plate and the pressure port 1 and outputted to the system. In the process of turning the rotor one turn, the pump sucks oil and pressure each time, so it is called single-acting pump. The rotor is subjected to radial hydraulic imbalance, so it is also called unbalanced pump, and its bearing load is large. By changing the amount of eccentricity between the stator and the rotor, the displacement of the pump can be changed, so the pumps are variable pumps.
Second, the working principle of double-acting vane pump
Its principle of action is similar to that of a single-acting vane pump. The only difference is that the stator surface is composed of two long-radius arcs, two short-radius arcs and four sections of transition curves, and the stator and rotor are concentric. . In the case where the rotor of the illustrated rotor rotates clockwise, the volume of the sealed working chamber gradually increases at the upper left and lower right corners, which is the oil absorption zone, which gradually decreases in the lower left corner and the upper right corner, and is the oil pressure zone; the oil absorption zone There is a section of oil seal between the oil and pressure zones to separate them. Each time the rotor of the pump rotates once, each sealed working chamber completes the oil suction and oil pressure operations twice, so it is called a double-acting vane pump. The two oil suction zones and the two oil pressure zones of the pump are radially symmetrical, and the hydraulic pressure acting on the rotor is radially balanced, so it is also called a balanced vane pump.
The instantaneous flow of the double-acting vane pump is pulsating, and the pulsation rate is small when the number of vanes is a multiple of four. For this reason, the number of blades of the double-acting vane pump is generally 12 or 16.
main feature:
In addition to anti-drying and overloading, anti-inhalation air and suction vacuum, the management points of the vane pump should also pay attention to:
● If the pump is changed in direction, the suction and discharge direction also changes the vane pump to have the specified steering, and it is not allowed to reverse. Because the rotor groove is inclined, the blade is chamfered, the bottom of the blade is connected to the oil discharge chamber, and the throttle groove and the suction and discharge ports on the oil distribution plate are designed according to the predetermined steering. Reversible vane pumps must be specially designed.
●The vane pump is equipped with the positioning pin of the oil distribution plate and the stator. The vane, rotor and oil distribution plate are not reversed. The suction part of the inner surface of the stator is most vulnerable to wear. If necessary, it can be flipped over to make the original suction zone. Become a drain and continue to use.
● Disassembly and assembly Note that the working surface is clean and the oil should be well filtered during operation.
● The gap between the blades in the groove is too large, which will increase the leakage. If it is too small, the blades will not be able to expand and contract freely, which will lead to malfunction.
● The axial clearance of the vane pump has a great influence on ηv.
●Small pump -0.015～0.03mm
● Medium pump - 0.02 ~ 0.045mm
● The temperature and viscosity of the oil should not exceed 55 °C, and the viscosity should be between 17 and 37 mm2/s. If the viscosity is too large, oil absorption is difficult; if the viscosity is too small, the leakage is serious.
