Winter farm machinery put five off
First, maintenance off. After entering winter, it is necessary to perform a high standard maintenance on the tractor and thoroughly remove, clean, adjust and lubricate all parts of the tractor to ensure the oil circuit, circuit and water passage, and no oil leakage or water leakage. Leakage, no leakage, good starting engine when used, power, and good operation. Second, antifreeze off. The volume expansion of the water in the tractor's cooling system after freezing will freeze the radiator, tank, body, and cylinder head. Therefore, when the minimum temperature in the winter is close to 0 degrees, the water in the cooling system must be released in time after each use of the vehicle, and it must be thoroughly cleaned. Third, use oil off. The diesel used in tractors is generally No.10, No.0, No.10, No.20 and No.30. The number is the temperature of the freezing point. Diesel oil contains wax, which is generally 7 degrees higher than the freezing point, there will be wax precipitation, at this time, its fluidity worse. Therefore, in the selection of diesel oil, the oil with a freezing point lower than the local temperature of 5 degrees to 10 degrees should be used. In addition, winter oil viscosity, will bring difficulties to lubrication and start should be replaced with No. 8 diesel engine oil. Lubricants in the gearbox and rear axle shall be replaced with No. 11 diesel engine oil or with No. 20 gear oil. Fourth, start off. Before starting the engine, it is necessary to fully warm up the body, and repeatedly add and release hot water under 90 degrees until the released water temperature reaches 30 degrees, and then add hot water over 90 degrees before starting. In the case of locomotives using batteries, the specific gravity of the electrolyte should be increased to 1.3-1.4, and should be charged after discharging 25% to prevent the electrolyte from freezing or decreasing in specific gravity. At the time of electric start, the time for each start shall not exceed 5 seconds, and once it starts, it shall stop for 1 minute before starting again. Fifth, security clearance. Leave the engine idle for a few minutes after starting the engine and cover the radiator insulation curtain. Keep the water temperature above 40°C, and start the engine only after the oil pressure is normal. Only when the water temperature is above 70°C can the load be operated. Traffic in winter should pay special attention to safety. Clutches, steering systems, brake systems, etc. must be carefully adjusted to make it flexible and reliable.
