7 柴油机故障及其排除柴油机故障使动力性、经济性指标下降、使用寿命缩短,甚至不能继续可靠地工作,酿成事故。因此,对柴油机故障不能等闲视之。柴油机产生故障,主要是由于不遵守操作规程,长期使用后零件的磨损、腐蚀、老化、疲劳点蚀、连接的松动等引起零件的损坏和变形,以及由此产生机件调整的破坏,加上技术保养不善,导致柴油机技术状态的不断恶化。正确使用和及时技术保养是防止和减少故障的最有效方法。一旦发生故障,必须及时检查、认真分析原因和判断故障发生的可能部位,及时排除,以免造成更大的事故。 7.1 起动困难主要由于环境温度过低,起动转速不够,燃油供给系统有故障,压缩压力不足等原因引起的。
7 diesel engine failure and its troubleshooting Diesel engine power, economic indicators decline, shortened service life, or even can not continue to work reliably, causing accidents. Therefore, the diesel engine failure can not be ignored. Diesel failure, mainly due to failure to comply with operating procedures, the wear and tear of parts after long-term use, corrosion, aging, fatigue pitting, loose connections and other parts caused damage and deformation, as well as the resulting mechanical damage to adjust, Poor technical maintenance, leading to the deteriorating technical status of diesel engines. Proper use and timely technical maintenance are the most effective ways to prevent and reduce malfunctions. In the event of failure, must be promptly checked, carefully analyze the causes and determine the possible parts of the fault occurred, and promptly ruled out in order to avoid a greater accident. 7.1 difficult to start mainly due to low ambient temperature, starting speed is not enough, the fuel supply system is faulty, compression pressure caused by insufficient and other reasons.
