In rural areas, there are often some operators who use agricultural machinery because they do not know how to maintain the technology or some bad habits that they usually develop, which causes the agricultural machinery to be damaged during use, thus reducing the service life of the agricultural machinery, mainly in the following aspects. :

First, the engine oil is added cumulatively. Many machine operators do not replace all the oil when they change the oil. Instead, they add new oil to the crankcase, so that the oil continuously “accumulates”. It is mistaken to do so, which not only ensures the lubrication of the diesel engine, but also saves money. As everyone knows, the oil has deteriorated after long-term use, the impurities increase, and the lubrication quality decreases. At this time, even if the new oil is often replenished, the quality of the oil can not meet the requirements, resulting in faster wear of the parts, greatly shortening the cylinder liner, piston and other machines. The service life of the piece. At the same time, a large amount of impurities in the oil will adhere to the oil passage wall, and in severe cases, the oil passage will be blocked, resulting in failures such as holding shafts and burning tiles.

Second, adjust the valve clearance at will. Most of the operators do not need special tools to check, but the size of the valve clearance is judged by shaking the feel of the valve rocker arm. This will affect the operation of the diesel engine. The lighter fuel consumption increases and the engine power decreases. It collides with the valve and even causes major failures such as rotten pistons, broken links, broken crankshafts, and cylinders.

Third, do not clean the exhaust pipe carbon deposits for a long time. Most of the operators neglect the maintenance of the exhaust pipe of the locomotive, and do not clean the carbon deposits of the exhaust pipe for a long time. As a result, the cross section of the exhaust pipe is narrowed and the exhaust gas is blocked, resulting in an increase in fuel consumption of the engine, a decrease in power, and "overheating". phenomenon. Therefore, in general, the exhaust pipe coke should be cleaned once a quarter to ensure that the diesel engine exhaust is smooth.

Fourth, the new machine will not be put into operation and put into the load operation. After purchasing the new machine, in addition to the inspection and maintenance, it must be run in strict accordance with the test run procedures specified in the factory manual. The speed is from low to high, and the load is light to heavy to eliminate the uneven surface of the friction surface. Traces to make the surface smooth. After some machines bought back the new agricultural machinery, they did not press the test run-in to the machine and directly put into operation, resulting in a greatly shortened service life of the machine.

5. No inspection before and after the operation. Many operators do not take the inspection before and after the operation, causing the agricultural machinery to loosen, fall off, and even harm the human body during the operation. Therefore, before and after the agricultural machinery is put into operation, it is necessary to carefully stop the bolts, nuts, split pins, etc. in various parts. The loose parts should be tightened in time, and the lost parts should be repaired in time. The worn and deformed parts should be repaired immediately to avoid small loss. (Wandan)
