In the cold winter, the fuel flowability of agricultural machinery deteriorates, the viscosity of lubricating oil increases, and the water is prone to freezing, which brings many difficulties to the use and maintenance of agricultural machinery. In order to improve the service life and economic benefits of agricultural machinery, a series of effective insulation and antifreeze measures should be adopted for agricultural machinery in winter.
1. Cover the engine with insulation curtains and insulation cover. If necessary, use cardboard to block the wind in front of the tractor radiator to reduce the entry of cold air. Insulation of the tractor is not good, it is difficult to start, but also will aggravate machine wear, therefore, the engine should be fitted with insulation or insulation curtain. Some engines equipped with organic oil radiators should be toggled to the "Winter" position so that the oil does not flow through the oil radiator. Cold areas should be replaced with low freezing point winter oils, such as diesel No.10.
2. Tractors and other agricultural machinery should be parked in the garage as much as possible to prevent wind, sun, rain and snow erosion and freezing.
3. Thoroughly clean the filter, oil pan, and transmission. Otherwise, different grades of lubricant will be mixed to reduce the lubrication effect.
4. Replace fuel and lubricants for winter use in a timely manner. In winter, fuel with a low freezing point should be used. Diesel with a high freezing point is easily solidified and the engine cannot be operated. As the viscosity of ordinary lubricating oil increases as the temperature decreases, resulting in poor fluidity, the frictional resistance increases when the machine moves, and the cold start is often caused when the tractor is started, and even accidents such as burning of tiles and axle suspension occur. Therefore, in the winter, oils in oil pans, air compressors and hub bearings should be replaced with lubricants used in winter; gear oils in transmissions, transfer cases, differentials, and steering gears should be changed. Gear oil used in winter.
5. Thoroughly clean the tank. In order to ensure the purity of diesel oil and reduce freezing, it is also necessary to clean the fuel tank frequently. It is generally required to clean it once every 20 days. It must not be brushed when cleaning, and it can only be cleaned with gasoline or diesel oil. If the inside of the paper filter element is found to be deformed or worn out, it should be replaced with a new one. The pressure regulator on the filter seat cannot be cleaned with gasoline, so as not to damage the sealing gasket of the pressure regulator valve. Conditions can be installed antifreeze fuel tank device, with oil tank insulation cover antifreeze, so that the tractor in the normal winter energy saving start and drive.
6. Fill and replace antifreeze in time. Before using antifreeze, first remove the original antifreeze from the engine and then clean the waterway. It is best to fill the antifreeze specified by the manufacturer to avoid damaging the waterway in the future. In addition, the amount of antifreeze should be appropriate, and must not be ignored.
7. Put the cooling water. When the water is drained, the water release switch should be fully open (normally the engine has two discharge switches, one on the cylinder block and one on the outlet of the bottom of the radiator) and the radiator fill cover. After the water is drained, the engine can be started to run for a while. In order to drain the cooling water. In addition, the cooling system should be cleaned before entering the winter to prevent debris from clogging the radiator and the engine drain switch.
8. Regularly release the water in the fuel tank to strictly prevent the water from mixing into the diesel oil to prevent the diesel from freezing.
9. Properly increase the proportion of battery electrolyte, use the method of charging to keep the battery in a fully charged state, so that the battery will not lose too much capacitance due to low temperature and the battery shell will freeze.
