Spring plowing is on the verge. The maintenance of agricultural machinery should be implemented in advance. Failure to maintain it in place will directly affect the use and longevity of the agricultural machinery. However, due to the improper application of some agricultural machinery operators when using and maintaining agricultural machinery, the agricultural machinery is damaged during use and maintenance, and the service life of the agricultural machinery is reduced. Therefore, here, the agricultural operator is reminded to pay attention to the following four when maintaining farm machinery before spring plowing. point: 1. The new machine uses the first run-in. After repurchasing the new agricultural machine, in addition to inspection and maintenance, it must be run in strict accordance with the commissioning procedures stipulated in the factory manual. The rotation speed should be from low to high, and the load should be light to heavy in order to eliminate the processing marks on the friction surface of the part and make it available. The smooth surface helps to extend its life. 2. Clean the exhaust pipe in time. Many operators ignore the maintenance of the exhaust pipe of the locomotive during operation. The long-term failure to clean up the carbon deposit of the exhaust pipe will narrow the cross-section of the exhaust pipe and obstruct the exhaust. As a result, the engine's fuel consumption rate will increase and the power will decrease. "Overheating" appears. Therefore, under normal circumstances, at least once a quarter to coke exhaust pipe to clean up to ensure that the exhaust engine exhaust. 3. Empty the oil regularly. When replacing the oil, many operators did not replace all the oil. Instead, they added new oil to the crankcase. This not only failed to meet the operating requirements, but also resulted in accelerated wear of the parts and greatly shortened the service life of the piston and other parts. At the same time, a large amount of impurities in the residual oil will adhere to the wall of the oil gallery, and in severe cases it will block the oil passage. Therefore, it is very important to empty the oil regularly. 4. Do not arbitrarily adjust the valve. Most agricultural hands detect it by experience. They do not use special tools for inspection, but judge the size of the valve clearance by shaking the feeling of the valve rocker. This will have a serious impact on the diesel engine's work. Lighter fuel consumption will increase, engine power will drop, and heavy ones will cause serious piston and valve collisions, reducing the life of the agricultural machinery.
