In previous years, the rainy season will end today, but this year it seems that we are still under the threat of violence in the season that should have ended. Because of the heavy rain, there are more water in the road, and some places even have to rely on ships to travel. Just as people ridiculed, in addition to having a room and a car this year, you have to have a boat. Of course it is not realistic to buy a ship. We still rely on cars for our trips. However, the car cannot be used as a boat. When driving a car, it is necessary to pay attention to whether the depth of water allows the vehicle to pass through. We often hear people talk about the depth of a certain car's maximum wading, and then the maximum wading depth is not accurate. Can it be used as a criterion for passing water? The answer is: According to the environment, the surrounding vehicles to comprehensively determine the driving situation, can not blindly believe that the maximum wading depth, otherwise you can eat a big loss, affecting the trip does not say, serious will take the car to go. The theoretical wading depth, the first is to look at the height of the exhaust pipe, a slight intake of the exhaust pipe does not cause a flameout, but if the flooded too deep the vehicle will also turn off, and the water will back into the car instantly make hot A three-way catalytic converter cools the permanent damage of the three-way catalytic converter. Second, half the height of the wheel is used as the standard for wading through. However, this standard has no scientific basis and is for reference only. Third, the height of the engine intake. This is the ultimate standard of wading in a car. When the air inlet enters the water, it will be extinguished because there is no air intake, and even it will absorb water and enter the engine to cause permanent damage to the engine. Only overhaul can solve it. However, this is only a theoretical height. The situation in real life is not so ideal. When you are driving in the water, though it is moving forward slowly, it will still provoke splashes, especially in the front part; other vehicles pass by especially large vehicles, such as public transportation. Because of the large size of the car, and because the engine's rear-end driving speed will be faster, the water waves that ignite will be even greater. Once the air intake is sucked into the rain, it is inevitable that the engine will be damaged. From this, we can know that the maximum wading depth does not guarantee foolproof. In heavy rain and rainy weather, we can drive without driving. If you really need to drive, you need to know ahead of time which road sections are seriously flooded and which road sections can pass. If you need to wading but you need to go on the way, you must take the vehicle off. If the water is too deep, do not force it to pass.
Boiler water walls are membrane walls that are made of tubes welded together with or without a strip of metal in between. These walls form the enclosure of the coal combustion chamber. Water wall tubes are also referred to as the evaporator section; they contain water mostly in liquid form which gradually evaporates as it rises in the boiler.
