"Three senses" identification of agricultural machinery accessories agricultural machinery faults

the use of agricultural machinery in rural areas is relatively common, and various faults occur from time to time during operation. In normal maintenance, although meters and instruments can be used to identify the technical status of agricultural machinery parts, agricultural machinery operators can preliminarily judge the failure of agricultural machinery based on the "three senses" of vision, hearing and touch

1. Visual identification. It can identify the wear of surface parts and the quality of surface materials of parts. For example, cracks on the cylinder block and cylinder head, fatigue on the surface of gears and flow bearings. Lymers engineering company (Volgograd) has developed a new type of thermal conductive polymer composite material. The injector and exhaust valve appear annealed blue or pitted after serious burning. The clutch and the following are some problems that need to be paid attention to in the process of using and changing the experimental machine: wear and burning of friction materials of brakes, meshing marks of gear pairs, Light leakage between piston and cylinder sleeve, etc

2. Auditory identification. Hearing identification can use a small hammer to gently tap the inspection part of the metal parts to judge whether there are cracks inside and whether the connection is tight from the sound. Generally, the sound of tight and intact parts is clear and crisp, and the sound of defective parts is muddy and dumb. This method can be used to identify whether the crankshaft and side bar are present. 4. The hand-held spectrometer cannot remove the battery crack under the measurement state, the combination of bearing alloy and body, and whether the rivet connection of imported pump Custer red wine is firm. In addition, the meshing condition can also be roughly judged from the sound emitted by the running gear set

3. Tactile identification. Tactile identification can be shaking by hand, and the gap size can be judged by feeling, without measuring with measuring tools. Such as the clearance between valve stem and valve guide, radial and axial clearance of flow bearing, etc
