Emergency Stopping

Usage:

3508B BPX


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。


发动机停机后要确保辅助发动机运行的外部系统的所有部件都是安全可靠的。

紧急停机按钮

使用紧急停机按钮会关闭燃油系统。 如果发动机装备有空气关断阀,空气关断阀也将启动。关于如何使用紧急停机按钮,请参见原设备制造厂家 (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。


重新起动发动机前使紧急停机按钮复位可能是必要的。

如使用紧急停机按钮,重新起动发动机前必须使两个空气关断阀都复位。

重新起动发动机前必须断开并重新接通 ECM 的电源。

以前机型

重新设定空气关断阀。

当通往电磁阀的电源被中断时,空气关断阀由机油压力启动。 每一个空气关断阀使用一个绕轴旋转的圆板来关断通往后冷却的进气。 发动机因通往燃烧室的空气供给受到限制而停机。 空气关断阀将在以下情况下启动:

注: 用户可以装备一个开关以便启动空气关断阀。

  • 按下紧急停机按钮。

  • 空气关断阀被启动。

  • 发生超速停机。

  • 电子控制模块电源断开。

把回位手柄转到"打开 (OPEN) "位置来使空气关断阀回位。 为在新机型上进行空气关断阀回位,转动六角手柄直到指示灯处在 "打开 (OPEN) "位置。

确保两个空气关断阀都复位。
