Guide: to prolong the service life of agricultural machinery and save the cost of purchasing and repairing agricultural machinery, there are many problems to pay attention to in use and daily management. The rational use of agricultural machinery is also the premise to ensure its correct driving, safe operation and minimize the occurrence of various agricultural machinery accidents.

To prolong the service life of agricultural machinery and save the cost of purchasing and repairing agricultural machinery, there are many problems to pay attention to in use and daily management. The rational use of agricultural machinery is also the premise to ensure its correct driving, safe operation and minimize the occurrence of various agricultural machinery accidents.

1. Pay attention to prevent the engine temperature from being too high. In most cases, the water tank is short of water. At this time, do not add cooling water immediately, which will cause the cylinder head or cylinder block to burst and scald personnel. The correct way is to stop the operation, run at a low speed, and slowly add clean cooling water when the water temperature drops to about 70 ° C.

2. Pay attention to prevent the engine water tank scale from being too thick. The engine water jacket scale is too thick, which will reduce the heat dissipation efficiency by 30% - 40%, which is easy to cause the engine to overheat and reduce the power. Therefore, the scale should be cleaned regularly to maintain good cooling performance.

3. Pay attention to prevent air resistance in the fuel system. Once air resistance occurs in the fuel, stop the engine immediately to cool down, and pull the hand oil pump to remove the air to fill the oil circuit with fuel.

4. Pay attention to prevent the viscosity of the used oil and lubricating oil from changing with the temperature. If the temperature increases, the viscosity decreases. Eca-30 or eca-40 diesel engine oil shall be selected in summer.

5. Pay attention to prevent the loose tightness of the fan belt. When working at high temperature, the belt tension decreases, resulting in belt slip, reduced transmission efficiency and easy damage to the belt. Therefore, the tension of engine adhesive tape shall be slightly higher than the standard value when the engine is cold in summer.

6. Pay attention to prevent fire. Always check and fasten all wires and fuel pipe joints to prevent fire caused by poor contact or fuel pipe leakage.

7. Pay attention to prevent high tire pressure, temperature rise, air thermal expansion volume increase, which is easy to cause tire burst. The inflation of tires in summer shall be 5% - 7% lower than that in winter, and it is never allowed to be higher than the standard pressure of tires.

8. Pay attention to prevent air resistance of oil brake pipeline. In summer with high temperature, air resistance of oil brake pipeline is easy to occur, which seriously affects the braking effect. Therefore, in use, first, ensure sufficient brake oil, second, prevent pipeline leakage, and third, discharge the air in time when air resistance occurs. To sum up, there are some precautions when using agricultural machinery in summer. The temperature is high in summer, so we must pay attention to fire and other phenomena.
