Due to the cold weather in winter, there are many difficulties in the use and maintenance of agricultural machinery. The engine is difficult to start and the fuel consumption increases. It is prone to freezing and prone to traffic accidents. In order to improve the service life and economic efficiency of agricultural machinery, a series of effective measures for insulation and antifreeze should be taken in the winter, and read “Insulation and Antifreeze Waresâ€: First, strengthen the body insulation 1, tractors and other agricultural machinery should be parked in the garage as much as possible to prevent erosion and freezing by rain and snow. 2, start the engine must be warmed up in advance, the method is: to the cooling system filling 60 °C hot water, pause, release and then heat the water until the temperature reaches 40 °C or more to start; release lubricating oil, water After heating, it is injected into the machine (note that the oil pan cannot be directly heated with an open flame); use an electric flame preheater for a short time. 3, cover the engine insulation curtain, insulation sleeve, if necessary, in front of the radiator with cardboard blocking the wind. 4, some engine with organic oil radiator, should switch the switch to the "winter" position, so that the oil does not flow through the oil radiator. Second, to prevent freezing machine parts 1. After the day's operation is completed, the small throttle should be operated for a few minutes. After the standby temperature is lowered, the flame is turned off and the cooling water is discharged. Pay attention to not be able to operate with full throttle, full power, sudden flameout, and immediate release of water to prevent the body from cracking due to sudden cooling. When opening the water tank cover and all drain switches, be sure to drain the net. Not only in the winter, but also in the late autumn, early spring, and the cold wave, when the temperature may reach 5 °C or less, pay attention to the release of water. 2. In the cold season, antifreeze should be added to the cooling water. 3. 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. 4. Appropriately increase the proportion of battery electrolyte (1.28 to 1.31), and use a supplementary charging method to keep the battery in a fully charged state, so that the battery will not lose too much capacitance and freeze-cracking batteries due to low temperatures. shell. three. Correct selection of oil 1. Because diesel contains paraffin components, when the temperature drops close to the freezing point of diesel (above 7°C), there is precipitation of paraffin and blockage of the oil circuit. Therefore, the freezing point of the selected diesel should be higher than the ambient minimum temperature of 5 °C ~ 10 °C, you can choose low freezing point, good fluidity 0,-10,-20 light diesel oil. 2. For lubricants, on the basis of the lubrication system, use winter lubricants such as CA20 (original grade HC-8), CA30 (original grade HC-11), etc., which are less viscous, or use thickening. Oil, which contains Additives that increase the viscosity at high temperatures and lower the viscosity at low temperatures, improves engine cold start performance. In the transmission and rear axle, No. 20 gear oil is available. 3, in the hydraulic system, optional 40 hydraulic oil. 4, in order to reduce the viscosity of grease (commonly known as butter), reduce the engine's running resistance, the number should be selected in the winter of small grease. For example, No. 1 and No. 2 lithium grease. Fourth, pay attention to driving safety When the tractor is engaged in road transport operations, due to the frozen road surface, the attachment performance between the tractor's walking device and the road surface is deteriorated, and the tires are prone to slipping and a driving accident occurs. To this end: 1. To control the speed of the vehicle, do not exceed the speed and overload; Should make full use of the engine's drag effect. 2. When driving on icy and snowy roads, you should select the front wheel rim to avoid slamming the steering wheel and emergency braking. Otherwise, the vehicle is prone to sideways slipping and cause a car accident. 3, in order to prevent slipping, you can add snow chains on the drive wheel. 4, with the car with triangular wood, shovel and other tools. Once the car is trapped, remove the floating soil immediately and do not slam the clutch.
