There have been investigations and more than five years of driver rear-end accidents. Because they feel good about themselves and drive faster, but they have already caused an accident when they act. On the other hand, novice driver's rear-end accident is relatively small, so the old and new drivers must pay attention to the distance in the end is it? How to maintain the distance? Baidu Encyclopedia of the interpretation of the safety car distance is: when the motor vehicle driving on the highway, the speed exceeds 100 kilometers per hour, the safety car distance is more than 100 meters; the speed is less than 100 kilometers per hour, the minimum safety car distance may not Less than 50 meters. The reason why the start-to-talk novice driver was caught in a rear-end accident was that many novice drivers did not know how to determine the safe distance from the beginning, but they remained vigilant and the speed was slow, so that there was enough time to deal with the previous car. distance. At this time, it also involves the problem of safe vehicle distance. How should the old and new drivers judge the safety car distance? In response to this, some old drivers who have had an accident have had a simple, easy-to-learn method for determining the distance between the front and the rear, called the "three-second distance." The specific determination method is: Before the car passed a certain marker, it took three seconds. After three seconds your car arrives at the marker and is within safe distance. If you reach or pass the marker within three seconds, it means that the safety distance is not enough. When the safety distance is not enough, the front vehicle will be braked. In most cases, your car will collide. This decision method has already recorded the speed of the two vehicles before and after, which is simple and easy. The faster the speed, the longer the three-second distance travels. If you have a good vision ahead of you, you can see the driving conditions of several cars in front of you. The three-second car distance can be flexibly controlled and shortened appropriately. When the front is a big passenger, especially a large truck, do not think that the distance of the front brake is longer than yours, or that you should keep the distance of three seconds. The accidents caused by the rear-end collisions with large trucks are always fearful and uneasy. Many drivers will use this three-second distance and feel useful for driving safety
It is mainly used for cooling the hot pellets come out of Pellet Mill. The high temperature 70°C-90°C pellet after cooling is less than 3°C-5°C ambient temperature, and reduce to safe moisture content. The cooling pellets not only increase the pellets hardness but also prevent mildew, eaay for storage and transportation.
The counter flow cooling principle is adopted to cool the pellets with high temperature and high moisture. Hot air touches hot pellets and cool air touches cool pellets so as to avoid the pellet surface crack by shock cooling produced by direct contact between cool air and hot pellets. At the same time, the airclosed airclock is adopted for feeding and bigger air inlet area, therefore it can get better cooling effects.
