Do not start the fire and add cooling water. After the agricultural vehicle was started, the temperature of the engine body rose rapidly and the instantaneous temperature of the combustion chamber could reach more than 1000 degrees Celsius. At this time, adding cold water to the tank, it is easy to cause the body, cylinder liner, cylinder head and vortex chamber inserts to crack due to rapid cooling, the piston. Linkages, etc. will also be deformed. The correct method is to fill the tank with 80°C hot water before starting.
Do not rush to release water after the agricultural vehicle is finished. In winter, the temperature is low, and the outdoor temperature is generally below 0°C. After the agricultural vehicle finishes its work, the cooling water is discharged if the flame is turned off. At this time, the temperature of the body is as high as about 90°C, and the temperature difference between the outside and the outside is large, and the cooling rate is fast, which easily causes the water tank. Cracking of engine parts, cylinder heads, etc. At this time, the engine should be idled for 5 to 6 minutes, and the temperature of the standby body should be reduced to 50~60°C before releasing the cooling water.
Pay attention when watching the water. When the agricultural vehicle is used for water discharge in winter, the operator should carefully observe the water discharge at the side of the machine. If the water flow is not smooth, the drain switch should be opened so that the cooling water in the machine body can be fully discharged.
After cranking the water, crank the crankshaft several times. When large and medium-sized agricultural vehicles put water, they often cannot drain the cooling water in the tank. After the cooling water in the tank is released in winter, it is necessary to crank the crankshaft several times to drain the water in the water channel.
3D Printing plastic process is the process about Cnc Machining. The heating head heats the hot melt material (ABS resin, nylon, wax, etc.) to a critical state, exhibiting a semi-fluid property. Under the control of the computer, the two-dimensional geometric information movement track determined along the CAD, the nozzle squeezes the material of the semi-flow state. Pressed out and solidified to form a thin layer of contoured shape.
