拖拉机故障虽然多种多样,情况复杂,但故障的发生却有一定的规律性,这就需要本着熟悉构造原理,牢记反常现象,按照从简到繁、从易到难、由表及里、减少拆卸、分段检查的原则进行诊断、分析与排除。(1)经验检查法主要是靠操作者的感觉器官,根据机器的反常现象,判断机器故障所在,从而使故障得以预防或排除。常用的经验检查手段有观、闻、问、触、听5种。(1)观察。观察机件的外部特征变化、运动情况、排气烟色、机油颜色、油水泄漏及液面变化的快慢、仪表读数、曲轴箱冒烟情况、火花塞与喷油嘴颜色情况等。如发
Although a variety of tractor failure, the situation is complicated, but the occurrence of the fault there is a certain regularity, which requires the principle of familiarity with the structure, keeping in mind the anomaly, according to from simple to complex, from easy to difficult, from the table and reduce Demolition, the principle of segmented inspection diagnosis, analysis and exclusion. (1) Empirical test method is mainly based on the operator’s sensory organs, according to the abnormal phenomenon of the machine to determine where the machine fault, so that failure can be prevented or eliminated. Common means of experience inspection, observation, smell, ask, touch, listen to 5 kinds. (1) observation. Observe the external characteristics of the parts changes, movement, exhaust smoke color, oil color, oil and water leaks and the speed of liquid changes, instrument readings, crankcase smoke, spark plugs and nozzle color and so on.
