The correct running-in and technical maintenance of new large and medium-sized tractors

In recent years, the implementation of the national agricultural machinery purchase subsidy policy has mobilized the enthusiasm of farmers to purchase and use agricultural machinery. Large and medium-sized tractors have also developed rapidly. The advanced and applicable large and medium-sized tractors have become more and more efficient and efficient. It has been welcomed by the majority of farmers and has become a way for peasants to become rich and make a good living. However, some users lack experience in the use of management technology, heavy use, light maintenance, and failure to perform break-in and technical maintenance according to technical requirements, resulting in premature aging of newly acquired tractor technology, affecting the performance of mechanical performance and shortening the service life. Unnecessary economic loss to users. Therefore, the majority of purchasers must use the newly purchased tractor correctly, reasonably and efficiently, pay attention to the running-in and technical maintenance of the tractor, and ensure a good state of technology in order to obtain maximum economic benefits.

First, we must do a good job of the tractor. Before the new tractor is used, it must be worn in. The running-in is an important means to extend the service life of the tractor. Because the parts after processing, the surface contains different degrees of tool marks, if you do not run into a large load operation, it will quickly make parts of the uneven friction surface damage, greatly enhance the part wear, thereby reducing Tractor life. The purpose of running-in is to gradually grind and smooth the rough and uneven friction surface, obtain a relatively smooth and hard pressure surface, and also get the most suitable fit clearance. After the tractor is put into normal operation, it can withstand the load and be extended. The service life lays a good foundation.

Tractor running-in should follow the following rules: 1. Preparation before running-in: check the external bolts, nuts, if there is loosening should be tightened in time; according to the lubrication table, add grease to each lubrication point, check the engine oil pan, transmission rear axle , Lubricator, front axle, steering oil tank, steering gear, air filter oil surface position, according to the lubrication table requirements on the lubrication part of grease or lubricating oil; add fuel and cooling water, check the electrical connection; The shift lever is in the neutral position, the hand throttle is in the idle position, and the hydraulic handle is in the lowered position.

2. Idling of the engine: After the engine is started, the engine is idled for 5 minutes, and then gradually raised to the nominal speed for air running. The idle running time of the engine should generally be about 15 minutes.

3. The running-in of the hydraulic system. Start the engine, manipulate the lifter handle, lift the suspension several times, observe whether the hydraulic system sucks the top card, and then hang the implement or weight with a weight of less than 500kg. Operate the lifter handle at the rated engine speed. The farm equipment will be raised and lowered steadily, with no less than 50 times. If the tractor is hydraulically steered and the tractor is stationary, the engine runs at low, medium, and high speeds, steering the steering wheel to see if it is light and steady.

4. The tractor idling running: In the idle running process, the engine speed should be controlled at about 1500 rev / min, the speed from low to high by the file, the final reverse gear running, the tractor idle running time should be about 5 hours.

5. The tractor's load running-in: Tractor load running is to bring a certain load to run, run-in principle: the load gradually increases from small to large, speed from low to high by file. The specific operation method differs from vehicle to vehicle. Refer to the load comparison table in the instruction manual. The normal running-in time should be more than 50 hours.

When running in, it must be strictly in accordance with the requirements of the instructions, not terrible trouble and reduce the running-in or shorten the running-in time.

6. Maintenance after running-in: after running-in, there will be some metal dust or dirt in the transmission system, lubrication system and hydraulic system mixed in the lubricating oil, so it is necessary to clean and replace all the lubricating oil and hydraulic oil. The lubricant and hydraulic oil should be released when the engine is shut down and shut down. After the cleaning is completed, the new lubricant and hydraulic oil should be added as required. When replacing the lubricating oil, the respective filter should be cleaned or replaced as required. In addition, the necessary maintenance and adjustment of the tractor must also be carried out in accordance with the instructions for use.

Second, do a good job of technical maintenance of the tractor

1. Should pay attention to frequency technical maintenance and cumulative working time technical maintenance

Shift maintenance is carried out at the beginning and end of each shift. It mainly includes auscultating the engine for abnormalities and checking the instrument, removing dust and dirt; checking the oil sump of the engine and the oil level of the gearbox; insufficient to add; checking whether the front and rear hub nuts are loose , Check and tighten the bolts and nuts of the brakes, steering gear and other key parts; check the air filter to remove dust; add grease to each lubrication point according to the lubrication table; squeeze out all the mud and water until the cleaning. Grease overflow; Check the tank, fuel tank level, lack of time should be added.

The accumulative working time technical maintenance is divided into multiple levels. After reaching a certain working time, this level of maintenance will be carried out and the maintenance items will be carried out according to the requirements of the tractor instructions.

2. Use clean oil

The fuel must be purchased at a reputable gas station to meet the national standard of diesel. The diesel can be used after 24 hours of sedimentation. The sediment cup should be cleaned frequently. In summer, diesel No. 0 is used, and in winter, diesel No. 10, No. 20, or No. -35 is to be replaced according to changes in temperature. Lubricating oil and hydraulic oil must be filled with plates and grades that are in compliance with the regulations. The oil used for transmission of hydraulic oil must be precipitated after at least 48 hours before use. Diesel engine oils of different brands and different manufacturers are forbidden to be mixed.

3. Do a good job of maintenance of the tractor storage period.

Farmland operations are seasonal and after a working season, tractors often have to store for a long time. Doing maintenance during storage is extremely important for maintaining a good state of technology. After the end of the work season, it is necessary to remove the engine oil from the heat engine, replace the engine oil, turn off the engine with a small throttle for a few minutes, fill the fuel tank with diesel, clean and maintain the air filter, and release the cooling water in winter. Place all the joysticks in the neutral position, adjust the tractor's front wheels and suspension rods to the lowest position; remove the batteries and put them in a room where the ventilation and light are not lower than 10°C. Check once a month if necessary. To supplement the charge; put the front and rear axles of the tractor up to make the tires slightly off the ground and let the tire air go away. In addition, according to the requirements of the tractor's instructions, check and adjustment of the valve clearance, fuel supply time, clutch stroke, etc. should be done so that the tractor is always in good technical condition.

Description:

Vitamin A is involved in the process of formation and preservation of function of epithelial tissues and mucous membranes, is important for fertility and is essential for vision. Vitamin D3 regulates and corrects calcium and phosphate metabolism in blood and plays an important role in the uptake of calcium and phosphate from the intestines. Especially in young, growing animal's vitamin D3 is essential for the normal development of skeleton and teeth. Vitamin E is as a fat-soluble intracellular antioxidant, involved in stabilising unsaturated fatty acids, thereby preventing toxic lipo-peroxides formation. Furthermore, vitamin E protects the oxygen-sensitive vitamin A from oxidative destruction in this preparation.


Indications:

Treatment and prevention of vitamin deficiencies in farm animals, such as growth disturbances, weakness of new-born animals, neonatal anemia, sight disturbances, intestinal troubles, convalescence, anorexia, not-infectious reproductive disturbances, rechitis, muscle weakness, muscular tremor and myocardial failure with difficulties in breathing; worm infections.
