Nowadays, in some rural households, the problem of “reserving lightly and reusing†is common. Here, I would especially like to awaken my farmer friends. It is worth watching out for the use of farm machinery in winter. 1. For agricultural machinery and tools that are not used for a long time in winter, paint should be applied in time and a thorough brushing and maintenance should be carried out. Remove dirt, oil, debris, etc. on the machine. The part where the machine is to be smooth should be filled with smooth oil and the body should be painted. Do a good job of preventing rust and corrosion. Can effectively extend the service life of equipment and avoid unnecessary loss of investment. 2, to have a rain and snow, anti-sun, ventilation, monotonous engine room (carport), do not store in the open air, so that anti-theft, security, fire prevention, safety retention. 3. When the temperature in winter is low and the locomotive is stagnated, cooling water must be drained in time. Irrespective of whether the tractors, agricultural vehicles temporarily used for temporary storage, agricultural vehicles, or joint harvesters that are not used for long-term storage, must open the radiator drain valve, cylinder water jacket drain valve and water tank cover, and crank the crankshaft after entering the warehouse. The water is completely depleted to prevent cold weather cracking the body. 4, in the winter cold frigid weather, the ambient temperature is low, start the engine, you must use hot water to join the cooling system, circulating warm-up engine. Open the water valve first, fill the water tank with hot water of about 70°C, until the discharge valve flows out of the hot water felt by the hot water, then open the drain valve and pour the water around the tank at about 90°C. When driving on icy and snowy roads, it is necessary to slow down the speed at a low speed, and the locomotive must maintain a certain distance from the people and vehicles in front; when turning, it is necessary to slow down and slowly return to the steering wheel. It is forbidden to drive at high speeds and compete for braking, so as to avoid causing a tackle accident. 5, select the appropriate grade of diesel oil. When the locomotive entered the winter, the fuel system should be cleaned. According to regulations, diesel and motor oil used in winter are selected. Usually, the freezing point of diesel oil is selected to be 5-10°C lower than the local temperature, and the engine oil must use the No. 8 diesel engine oil with low viscosity. Before adding the diesel fuel to the fuel tank, it usually takes 48-96 hours to accumulate. After filtering with a silk net, it is added to the fuel tank. Some operators, but also remove the filler filter, this approach is wrong. It will cause debris in the diesel fuel to enter the tank, exacerbating the blockage of the pump, wear of the outlet valve and precision fittings of the injector tip. Decreasing the oil supply pressure, deterioration of fuel injection performance, poor combustion of diesel fuel, and reduced power will greatly shorten the service life of the engine.
