目前,定量叶片泵上的定子,普遍采用等加速曲线,以实现容积变化。由于曲线升程大(相对正弦曲线)、变化剧烈(在0、α/2、α处有柔性冲击),圆弧、曲线交接多,故定子曲线的加工、检验一直存在问题。内曲线的质量好坏,直接影响泵的性能。从现有检测手段看,除了定子圆弧段孔径可用通用量具检测外,其他项目,诸如:曲线形状、对称度(中心对称、角度对称)喇叭口、垂直度以及局部缺陷均无法检查。定子内曲线比较仪是一台综合检查工
At present, the stator on the quantitative vane pump generally adopts the acceleration curve so as to realize the volume change. Due to large curve (relatively sinusoidal curve), dramatic changes (in 0, α / 2, α at a flexible impact), arcs, curves and more transfer, so the stator curve processing, testing there is always a problem. The quality of the curve is good or bad, a direct impact on pump performance. Judging from the current testing methods, other items such as curve shape, symmetry (center symmetry, angular symmetry), bell mouth, squareness and local flaw can not be inspected except for the aperture of the stator arc segment can be detected with a universal gauge. The stator curve comparator is a comprehensive inspection workers
