故障的根本原因如下:

  • 空气压力低

  • 导线

  • 控制阀

  • 中继阀

  • 马达

  1. 充入空气系统压力。

  1. 修理和/或更换导线。

  1. 修理和/或更换控制阀。

  1. 修理和/或更换中继阀。

  1. 修理和/或更换马达。

空气起动马达已失去电源。

故障的根本原因如下:

  • 空气压力低

  • 润滑不当

  • 零件磨损

  • 漏气

  1. 如有必要,充注空气系统。 检查空气系统有无泄漏。 检查空压机是否正常工作。

  1. 检查润滑系统。

  1. 检查零件有无磨损。 更换磨损的零件。

    1. 检查叶片有无损坏。 如果任意一端的叶片宽度低于 32 mm (1.25 in),则更换叶片。

    1. 检查转子轴承。 如果轴承松动或损坏,则更换轴承。

    1. 检查转子有无划伤。 试着利用砂布清除划伤。 如果划伤不能清除,则更换转子。

    1. 检查气缸有无裂纹和/或划伤。 如有必要,更换气缸。

  1. 检查有无磨损的密封。 封堵排气口后在进口上施加 205 kPa (30 psi) 的压力。 将装置放入不易燃的液体中 30 秒。 如果出现气泡,则更换马达密封。

小齿轮不与飞轮啮合。

可能的根源是离合器和/或其他零件断裂。 更换离合器。

小齿轮与飞轮啮合,但飞轮不转动。

可能的根源是轴和/或轮齿断裂。 检查轴和轮齿有无损坏。 更换所有损坏的零件。

小齿轮与飞轮间啮合不当。

可能的根源是小齿轮轴缺少润滑。 拆下小齿轮后在花键和小齿轮上涂抹润滑脂。
