All kinds of agricultural machinery should be repaired and maintained. During the maintenance of agricultural machinery, attention should be paid to:
1. Some drivers only know how to supplement the engine oil and ignore the quality inspection. As everyone knows, long-term use of oil contains a large number of oxides and metal shavings, resulting in reduced lubricating properties, parts wear increased. Therefore, the engine should be regularly changed according to the specified cycle.
2. Some drivers never clear the exhaust pipe and muffler carbon deposits, resulting in too thick carbon deposits, exhaust cross-sectional area decreases, resulting in exhaust gas exhaust, fresh air into the lack of combustion deterioration.
3. Some drivers never remove scale. Although the cooling water is sufficient, the cooling effect is poor, causing multiple failures.
4. The role of the oil valve is a seal, that is, the plunger oil chamber and the high-pressure fuel pipe to separate, so as not to return; second is to stop the decompression when the oil supply, to ensure that the fuel injectors cut off the oil simply. Even if the delivery valve is of poor quality or worn out, it will cause many diesel engine failures.
5. When the valve leaks, people are used to checking the valve and valve seat, and ignore the check of valve spring quality. It should be pointed out that the lack of elasticity of the valve spring is also one of the causes of the valve leakage failure.
