注意

紧急停机控制装置只用于紧急情况。 切勿把紧急停机装置或控制装置用于正常的停机过程。


确保发动机停机后,辅助发动机运行的外部系统的所有部件安全可靠。

紧急停机按钮

使用紧急停机功能会切断燃油。 同时也会启用空气切断阀。 有关紧急停机按钮的操作信息,请参阅设备 OEM 提供的说明。


注意

在找到迫使发动机紧急停机的问题并予以纠正以前,不要起动发动机。


重新起动发动机前可能有必要使紧急停机按钮复位。

如果使用紧急停机按钮,则必须首先复位空气切断阀,然后才能重新起动发动机。

重新起动发动机前必须断开并重新接通 ECM 的电源。

空气关断阀(如有配备)

(1) 手动释放按钮
(2) 作用轴

空气切断阀由油压促动。 空气切断阀使用一个移动板来阻止空气进入发动机。 发动机因通往燃烧室的空气供给受到限制而停机。 空气切断阀将在以下情况下开动:

  • 按下紧急停机按钮。

  • 空气切断阀启用。

  • 发生超速停机。

  • 电子控制模块断电。

手动释放按钮 (1) 是作为一种安全特性提供,可以允许维修人员在开始维修前释放切断阀。 手动释放按钮不得用于在运转的发动机上释放切断阀。 所需的拉动力为 316 至 414 N (71 至 93 lb)

注: 客户可以装备一个开关以便启用空气切断阀。

重新起动发动机前,必须手动复位空气切断阀。 要复位空气切断阀,使用棘轮转动作用轴 (2),直到轴锁入"开启"位置。
