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 adopted for agricultural machinery in the winter, mainly in the following four aspects: 1, strengthen the body insulation 1 Tractors and other agricultural machinery should be parked in a garage as much as possible to prevent them from being eroded by ice and rain. 2 start the engine to warm up in advance, by filling the cooling system with hot water of about 60 °C, stop for a while, release and then heat the water until the temperature reaches 40 °C or more to start; release the lubricant, insulation After the injection into the machine (note that the oil pan can not be directly heated with an open flame); short-term use of electric flame preheater and so on. 3 Cover the engine with insulation curtains and insulation sleeves. If necessary, use cardboard to block the wind. 4 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. 2, to prevent freezing machine parts 1 After the day's work is finished, the small throttle should be operated for a few minutes, and the standby temperature should be lowered before turning off and cooling water. 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 Properly increase the proportion of the battery electrolyte (1.28 to 1.31), use a supplementary charging method to maintain 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 . 3, the correct choice of oil 1 Because diesel contains paraffin components, when the temperature drops close to the freezing point of diesel (above 7°C or so), there is a precipitation of paraffin and the oil path is blocked. 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 lubricating oils, 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 thicker motor oils. It contains additives that increase the viscosity at high temperatures and reduce the viscosity at low temperatures, and can improve the engine's low temperature start-up performance. In the transmission and rear axle, No. 20 gear oil is available. 3 In the hydraulic system, optional No. 40 hydraulic oil. 4 In order to reduce the viscosity of grease (commonly known as butter) and reduce the running resistance of the engine, a small number of greases should be used in winter. For example, No. 1 and No. 2 lithium grease. 4, pay attention to traffic safety When the tractor is engaged in road transport operations, due to the freezing of the road surface, the attachment performance between the tractor's traveling device and the road surface is deteriorated, and the tire is liable to slip and cause a traffic accident. For this reason: 1 To control the speed of traffic, do not overspeed and overload; Do not slide on a slippery slope, and make full use of the engine's resistance. 2 When driving on icy and snowy roads, you should select the front wheel rim to avoid striking the steering wheel and emergency braking. Otherwise, the vehicle will easily cause a sideways slip and cause a car accident. 3 In order to prevent slippage, snow chains can be added to the drive wheels. 4 Carry tools such as triangular wood and shovels. Once the car is trapped, remove the floating soil immediately and do not slam the clutch.
