Winter agricultural machinery insulation antifreeze measures

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, fuel consumption increases, and it is prone to freezing. 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 Wares”:

First, to 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 and cracking machine parts, one day after the end of the operation, the small throttle should be running a few minutes, the standby temperature is reduced and then turn off the flame and put the 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 battery electrolyte (1.28 ~ 1.31), 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.

Third, the correct choice of oil, because diesel contains paraffin components, when the temperature drops close to the freezing point of diesel (above 7 °C or so) when the precipitation of paraffin, blocking the oil. Therefore, the freezing point of the selected diesel should be higher than the ambient minimum temperature of 5°C~10°C, and light diesel oils with low freezing point and good fluidity No. 0, -10, and -20 can be selected. For lubricating oils, on the basis of the lubricating system, use winter lubricating oils such as CA20 (original grade HC-8), CA30 (original grade HC-11) with low viscosity, or use thickened engine oil. It contains additives that increase the viscosity at high temperatures and lower 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 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.
