Damage to the five bad habits of agricultural machinery

When many engine oils need to be replaced, not all of them are replaced. Instead, fresh oil is added to the crankcase to make the oil “accumulate†continuously. This mistakenly means that it not only ensures the lubrication needs of the diesel engine, but also saves expenses. As everyone knows, oil after long-term use has deteriorated, impurities increased, lubrication quality decreased, at this time, even if often add fresh oil, oil quality can not meet the requirements, resulting in accelerated wear of parts, greatly reducing the cylinder liner, piston and other machines The service life of the parts. At the same time, a large amount of impurities in the oil will adhere to the wall of the oil passage. In severe cases, the oil passage will be blocked, resulting in the occurrence of troubles such as shaft-shafting and burning of tiles.
To adjust the valve clearance at will Most operators do not use special tools for inspection. Instead, they judge the size of the valve clearance by shaking the feel of the valve rocker arm. Even if it is true, it will affect the work of the diesel engine. The lighter fuel consumption will increase and the engine power will drop. In severe cases, the piston and the valve will collide, even causing the piston to rot, the connecting rod and the broken rod. Crankshaft, hit the cylinder body and other major faults.
Do not clean the carbon deposit of the exhaust pipe for a long time Most operators ignore the maintenance of the exhaust pipe of the locomotive. They do not clean the carbon deposit 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 engine fuel consumption. Increase, power drop, "overheating" phenomenon. Therefore, under normal circumstances, the exhaust pipe coke should be cleaned once every quarter to ensure the smooth exhaust of the diesel engine.
After the new machine is put into operation, the new machine is put into load operation to buy back a new machine. In addition to inspection and maintenance of the new machine, it must be run in strict accordance with the commissioning procedures specified in the instruction manual. The rotation speed is from low to high and the load is light to heavy. Eliminates the uneven machining marks on the friction surface of the part to make it smooth. Some operators bought back new farm machines and did not perform test run-in directly on the machines as required, resulting in a significant reduction in the service life of the machines.
Before and after the operation, many operators did not check that the inspections before and after the operation were not proper, which resulted in the loosening of parts of the agricultural machinery during operation and even harmed the human body. Therefore, before and after the operation of agricultural machinery, it is necessary to carefully stop the inspection of bolts, nuts, washers, cotters and other loose parts in time to tighten, the missing should be promptly filled, wear deformation of the parts should be repaired immediately, to prevent small losses.
