Agricultural vehicle winter water attention
1. Do not fire first and add cooling water After the agricultural vehicle is started, the temperature of the engine body rises sharply and the instantaneous temperature of the combustion chamber can reach over 1000 degrees. Therefore, when the cold water is added to the tank, the body, the cylinder liner, the cylinder head, and the vortex chamber insert will be easily cracked due to sudden cooling. Linkages, etc. will also be deformed. The correct method is to fill the tank with 80°C hot water before starting. 2. Don't rush to put water after the completion of agricultural vehicles. The winter temperature is low, the outdoor temperature is generally around 0°C, and the temperature in the north will be lower. After the agricultural vehicle finishes the work, if you just turn off the heat, let go of the cooling water. At this time, the body temperature is high. Around 90°C, large temperature difference with the outside, cooling speed, easily cause cracking of the water tank, engine parts, cylinder head, etc. At this time, the engine should be idled for 5 minutes to 6 minutes, and the temperature of the standby body should be reduced to 50°C to 60°C. Let go of the cooling water. 3. Pay attention to the observation of the release of water when the long-term use of agricultural vehicles, scale, impurities, etc. are likely to exist in the drain switch, causing the switch to block, so that the cooling water is not exhausted, causing the engine to crack. Therefore, when the agricultural vehicle is used for water discharge in winter, the operator should carefully observe the water discharge situation at the side of the machine. If the water flow is not smooth, the drain switch should be opened to allow the cooling water in the body to be fully discharged. 4. Turn the crankshaft after releasing the water. When the large-and-middle agricultural vehicle is opened and the water release switch is used to release water, the cooling water in the tank is often not used up. A part of the cooling water remains in the waterway, and there is still a frozen body. may. Therefore, after releasing the cooling water in the water tank in winter, it is necessary to crank the crankshaft several times to drain the water in the water channel.
