注意 |
---|
发动机带负荷运行后立即停机会引起过热并加快发动机零部件的磨损。 在发动机停机以前,让发动机逐渐冷却下来。 |
- 脱开被驱动设备。
- 对于发电机组,断开主断路器。
- 对于工业发动机,使压缩机或泵卸载。 分离离合器(如有配备)。 将变速箱和 / 或其它动力输出附件置于 NEUTRAL(空档)位置。
注: 在避免产生爆燃的速率下卸去负载。
- 降低发动机转速到低怠速。
注: 长期怠速会造成过量机油消耗和相关的问题。 请参阅本操作和保养手册, "发动机操作"专题(操作章节)。
- 在低怠速转速下运行发动机经过冷却时间。
如果之前发动机在低负载下运行,停机前让发动机在低怠速运行 45 秒 到 1.5 分钟。
如果之前发动机在高负载下运行,停机前让发动机在低怠速运行 3 到 5 分钟。
- 关断燃气供给以关停发动机。
发动机将逐渐停下来。 在发动机停机之后,确保为发动机运行提供外部支持的所有系统是安全可靠的。
