Metal casting processes divide into two categories basedon mold type: (l) expendable mold and (2) permanentmold. In expendable mold casting operations. the mold issacrificed in order to remove the cast part. Since a newmold is required for each new casting, production rates inexpendable-mold proc..

轴向活塞泵是一种典型的同轴的泵,它的汽缸和传动轴是平行的(如图4—13),它的往复运动被一个平板形凸轮带动,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汽缸筒的同一轴线所以不能旋转。在定量泵中,凸轮盘必须要严格的安装在合适的位置上结果它与汽缸筒的中心线以垂线方向倾斜25度的角度交叉。..
