Summer high temperature season is the busy season when agricultural machinery is engaged in harvesting, mechanical cultivation or irrigation and drainage. However, field operations are heavy and slippery. Therefore, overheating of machinery often occurs. Several cooling measures are introduced. 1, carefully remove the scale of the engine cooling system. When the scale thickness exceeds 1 mm, the cooling capacity of the cooling system will be significantly reduced. There are many chemical methods to remove scale, and the operator can inject 0.3%-0.4% aqueous solution with ammonium nitrate into the cooling system. The cleaning solution should be replaced after 4-5 days. 2. Check whether the amount of cooling water is sufficient, whether the tension of the pump transmission tape is too loose and slipping, whether the fan is deformed or reversed, and if necessary, replenish and adjust to maintain the normal working state of the cooling system. If the water tank is often panned, you should find out the reason and troubleshoot before you start the operation. You should not blindly pour cool water. 3, rational use of oil. In summer, diesel No. 0 or No. 10 should be used; engine oil pan with No. HC-11 oil; transmission, steering gear and rear axle with No. 90 gear oil. 4. Reasonably manipulate and adjust the unit's tillage depth and work width to prevent overloading of the unit and avoid a sharp rise in the temperature. Rinse dirt and oil from the body frequently, remove stalks or other debris from the gaps in the radiator to prevent it from dissipating heat. 5. When the machine is at rest, it should be stopped in a shaded and ventilated place to avoid the sun exposure.
