发动机冷却水泵叶轮装配高度检测方法的研究

发动机冷却水泵叶轮装配高度的常用检测方法有四种:用三坐标检测,用通止规类专用检具检测,用带有百分表的专用检具检测,用激光传感器组成的专用检测工位检测,这四种检测方法检测原理不同,判定方法存在差别。

There are four common measuring methods for the impeller assembling height of engine cooling water pump： CMM, go-no gogage, special gauge with dial indicator, special station built by laser sensor. These four methods have different theory, and the judgementmethods are also different.
