轴向柱塞泵 Axial Piston Pumps

轴向柱塞泵 Axial Piston Pumps(中文1900字,英文1300字)
轴向柱塞泵是一种典型的同轴的泵，它的汽缸和传动轴式平行的，它的往复运动被一个平板型凸轮带动，也叫摆动盘，倾斜盘，或旋转斜盘。这个盘位于一个平面穿过主动轴和气缸筒的同一轴线，所以不能旋转。在定量泵中，凸轮盘必须要求严格的安装在合适的位置上，结果它与气缸筒的中心线以垂直方向倾斜25度的角度交叉。变量传输的轴向柱塞泵的设计是有意图的，所以凸轮盘与气缸筒中心线的正交处变化范围在0°到20°或25°到两侧。每个活塞杆的末端被用来与凸轮盘相接触，因为汽缸体和活塞的转配同传动轴，一起旋转。这引起了活塞在气缸内的互换。活塞的长度是与角度成比例的，这个角度是凸轮盘的位置与气缸筒中心线垂直方向的角度。

Axial Piston Pumps
In axial piston pumps of the in-line type, where the cylinders and the drive shaft are parallel ,the reciprocating motion is created by a cam plate, also known as a wobble plate ,tilting plate ,or swash plate .This plate lies in a plane plate that cuts across the center line of the drive shaft and cylinder barrel and does not rotate .In a fixed-displacement pump ,the cam plate will be rigidly mounted in a position so that it intersects the center line of the cylinder barrel at an angle approximately 25 degrees from perpendicular .Variable-
delivery axial piston pumps are designed ,so that the angle that the cam plate makes with a perpendicular to the center line of the cylinder barrel may be varied from zero to 20 or 25 degrees to one or both sides. One end of each piston rod is held in contact with the cam plate as the cylinder block and piston assembly rotates with the drive shaft This causes the pistons to reciprocate within the cylinders .The length of the piston stroke is proportional to the angle that the cam plate is set from perpendicular to the center line of the cylinder barrel .
