Nowadays, many countries have opened rail routes, and people can easily travel to their destinations by train. It is precisely because of the great changes in transportation modes that we can enjoy better travel conditions. The mainland undertakes more important passenger and freight tasks, and trains run normally every day, promoting the transportation of goods between multiple cities, and people can also reach their destinations in a very short time.
In the process of taking the train, people enjoy the scenery along the way, and even some people will get off the train along the way, just to experience a different cityscape. Despite this, most passengers do not realize that the train needs to be sprayed with sand during the journey, so what is going on?
In the traditional impression, sand, as a particularly important building material for houses, is very expensive to sell, and the price of one ton of sand is maintained at about 100 yuan. Coupled with the labor cost of building a house, this makes people try to choose sand that is very cost-effective, thereby saving a part of the cost of building materials. Against this backdrop, many people can't predict that sand will come in handy before the train travels, and even when multiple trains face emergency braking or special weather, they will activate the sandblasting device.
In fact, when the train starts or goes uphill, the drag becomes very large. At this time, there is no very strong friction between the rail and the wheel, and it is very likely that a slip will occur. Let's take a simple example, for example, people drive a particularly cost-effective car, the car is driving on the road in winter, and a thin layer of ice is formed on the road. In this way, the friction between the wheels and the road surface is greatly reduced, the wheels cannot function normally, and the car is particularly easy to slip, affecting safe travel.
Whenever the car has less friction with the ground, the car cannot run normally, and people will think of various ways to make the car work normally. Among the many methods, this includes sprinkling a thin layer of sand on the ice. In this way, sand increases friction between the two, and grainy sand increases wheel friction. Whenever people use this method, the situation of the car slipping will be greatly improved.
In fact, the principle of the staff to start the train sandblasting device is very consistent with the principle of preventing the car from slipping. Due to the large number of carriages on the train, each carriage contains a large number of goods and some passengers. Although the train has a very high train power, while increasing the power, the staff needs to take into account the particularly realistic problems to prevent the train from slipping for a long time.
Skidding will affect the normal operation of the train, and it is particularly difficult to speed up the train. At this point, one must come up with a very reasonable solution that increases the friction between the track and the wheels and indirectly increases the traction of the train. When the friction between the train and the rail is very normal, the train can maintain a smooth running state and ensure that the train reduces the probability of slippage in the process of running.
In general, trains have changed the way most people travel, and many people's preferred means of transportation when traveling to long-distance destinations is the train. However, many people only care about the internal environment of the train, but they never understand many small details of the train's operation. The train sandblasting device is not optional, but the relevant personnel in the process of continuous accumulation of experience, and finally establish a small setting to ensure the normal operation of the train.
The device can increase the friction between the train wheels and the rails, and when the train is normally started, the sandblasting device plays a role, increasing the friction between the two, thus ensuring the normal operation of the train and continuously transporting passengers to their destinations. This is not only the wisdom of human beings, but also reflects the continuous progress of trains.
