How can agricultural machinery avoid "heat stroke" during hot summer days?

As the weather gets hotter, people are thinking about how to avoid the heat. Like people, agricultural machinery is also required to spend the summer, then how can the agricultural machinery to avoid "heat stroke" in the hot summer? In summer, when temperatures are high and agricultural machinery is working in a high-temperature environment, special attention should be paid to the following issues:

1. Be careful about "cooking." When the cooling water “opens the pot,” be careful. The correct way to deal with this is to allow the engine to run at an intermediate speed, open the radiator cover, and release hot air. After cooling, slowly add cold water. When opening the radiator cover, the operator should stand in the upwind position, face not to face the water inlet, so as not to be burned by the high-temperature vapor spray.

2, keep the cooling system clean. Before the arrival of summer, the cooling system should be thoroughly cleaned and cleaned to ensure that the water pump and the radiator pipe are kept open and the cooling water can be circulated properly. In addition, weeds and other objects left on the surface of the radiator should be promptly cleaned.
It is necessary to clean the oily surface of the engine in time. If the oil is too thick on the outside of the engine, it will affect heat dissipation, and it will cause hidden troubles for various parts and components. With the method of high-pressure injection, it will not corrode the cleaning agent of the body parts to clean the engine parts.

3, to prevent leakage. Leakage of the cooling system occurs at the water pump bushings. The water seal nut must be tightened properly. If it is invalid, it indicates that the packing has failed and should be replaced in time. Filler can be wound with graphite powder coated asbestos rope.

4, pay attention to the tightness of the belt. If the fan belt is too loose, it will slip easily, causing the speed of the fan and the pump to drop, resulting in insufficient wind power. If the fan belt is too tight, the bearing load will be too large, which will increase wear and increase power consumption. It is generally required that when the thumb is pressed in the middle of the belt, the amount of belt sag is 10 to 15 mm. Too loose or too tight should be adjusted in time.

5, the correct use of temperature control device. Thermostats are available in both automatic (eg thermostat) and manual (eg thermal screens and blinds). Some drivers think that it is hot in summer and the lower the water temperature, the better. So remove the thermostat. In doing so, the warm-up time of the engine will be greatly prolonged when the cold car starts, and the wear of the parts will be accelerated. Therefore, the thermostat should not be removed during the summer. The heat-insulating curtains and shutters are used to regulate the amount of wind passing through the radiator. In general, no heat-preserving curtains are needed in summer, and the blinds should also be placed in the fully open position.
Look at the temperature of the water table to prevent water shortage: In high-temperature weather, the water in the water tank evaporates faster. Always check the amount of cooling water and pay attention to the water temperature table. When you find water shortage, immediately idling and then add water, and be careful not to immediately open the radiator cover to prevent scalding.

7, the correct choice of oil. Summer temperatures are high and diesel with higher freezing point can be used. In addition, special attention should also be paid to preventing oil spills in the oil supply system because oil spills not only result in wastage of oil, but also cause fires. In addition to diesel, lubricants and greases should also be selected for summer use. Some tractors have an oil-temperature reversing valve. During the seasonal maintenance, the reversing valve should be switched to the position where the oil is connected to the oil radiator.
Anti-deterioration of oil: Lubricants are vulnerable to heat thinning, poor oxidation resistance, perishable, and even cause failures such as the burning of the bearing bushes. Therefore, the crankcase and gear box should be replaced with summer lubricants, and the quantity of oil and oil quality should be checked frequently and replaced in a timely manner.

8, pay attention to the maintenance of the battery. In the summer, moisture in the battery electrolyte evaporates easily. Special attention should be paid to checking the liquid level of the battery. The normal liquid surface should be 10 to 15 mm above the plate, and the electrolyte density of the battery should be adjusted according to regulations. The ventilation holes on the filler cap should be dredged. In addition, temporarily unused batteries should be stored in a cool, ventilated place.

9, anti-burn oil and gas resistance. The higher the temperature is, the faster the evaporation will be, and the easier it will be to form a gas barrier in the oil circuit. Therefore, the fuel filter should be cleaned in summer to keep the oil line open. A wet cloth can be placed on the fuel pump during driving, and the watering can be kept constant to prevent the generation of air resistance. Once the air resistance occurs, the temperature should be immediately stopped to make the oil filled with fuel.

10, prevent engine deflagration. Deflagration of the engine due to overheating will increase the wear on the upper part of the cylinder by 3 to 5 times. Therefore, to completely remove the carbon deposits in the combustion chamber, valve head, etc., check and adjust the fuel supply and fuel supply time to prevent explosion. Cool explosion-proof tires: Summer temperatures are high, and tire rubber is prone to aging. In severe cases, a puncture occurs. Therefore, the tractor should check the tire pressure at any time during the trip and find that the tire is overheated and the air pressure is too high. Stop the vehicle in a cool place and cool down. Do not pour cold water on it and do not put it there. Otherwise, it will cause a puncture on the way.

11, prevent fire. Always check the fastening of the wires and the fuel pipe fittings to prevent sparks due to poor contact or fuel pipe leakage. Do not store oil in plastic buckets to prevent static electricity from catching fire. Under lightning conditions, tank oil must not be overfilled to prevent spillage and fire.
