水泥撒布車灑布不均勻是我們?cè)谑褂盟嗳霾架囘^(guò)程中經(jīng)常會(huì)遇到的問(wèn)題，為此問(wèn)題的引起的原因和方法公布如下，以方便購(gòu)車朋友在遇到此類問(wèn)題時(shí)能及時(shí)，解除大家用車中的煩惱。
The uneven distribution of cement spreader is a problem we often encounter in the process of using cement spreader. The causes and solutions of this problem are announced as follows, so as to facilitate the car buyers to solve such problems in time and relieve the troubles in the car.
水泥撒布車灑布不均勻的主要原因：
The main reasons for uneven distribution of cement spreader are as follows
1.檢查瀝青噴嘴是否松動(dòng)或者有堵住的現(xiàn)象；
1. Check whether the asphalt nozzle is loose or blocked;
2.瀝青噴嘴位置不統(tǒng)一；
2. The position of asphalt nozzle is not uniform;
3.車速過(guò)快或者過(guò)慢；
3. The speed is too fast or too slow;
4.瀝青粘度過(guò)大；
4. The viscosity of asphalt is too high;
5.噴灑管離地高度過(guò)高或者過(guò)低。
5. The height of spraying pipe from the ground is too high or too low.
水泥撒布車灑布不均勻的方法：
Solution to uneven distribution of cement spreader
1.清理全部瀝青噴嘴檢查是否有損壞的噴嘴及時(shí)更換；
1. Clean all asphalt nozzles, check whether there are damaged nozzles and replace them in time;
2.把瀝青噴嘴全部調(diào)整到統(tǒng)一位置；
2. Adjust all the asphalt nozzles to the same position;
3.降低車速控制均碼灑布；
3. Reduce the speed and control the uniform distribution;
4、使噴灑管離地高度可調(diào)，閉環(huán)控制。
4. The height of the spraying pipe from the ground can be adjusted and controlled in closed loop.
由于噴灑扇面角會(huì)受到車速、瀝青種類、溫度、粘度等因素影響，所以離地高度盡量根據(jù)施工經(jīng)驗(yàn)確定，并以此作為依據(jù)進(jìn)行調(diào)整：噴灑管離地高度太大，會(huì)減小瀝青噴灑沖擊力，弱化“沖擊一飛濺～勻化”作用；噴灑管離地高度過(guò)低，會(huì)減小瀝青噴灑扇面重疊數(shù)，應(yīng)根據(jù)實(shí)際情況調(diào)節(jié)噴灑管高度以提高瀝青噴灑效果。
Because the angle of the spraying fan is affected by the speed, asphalt type, temperature, viscosity and other factors, the height above the ground should be determined according to the construction experience as far as possible, and adjusted on this basis: if the height of the spraying pipe above the ground is too high, the impact force of asphalt spraying will be reduced, and the effect of "impact splash homogenization" will be weakened; If the height of spraying pipe is too low, the overlap of asphalt spraying fan will be reduced. The height of spraying pipe should be adjusted according to the actual situation to improve the asphalt spraying effect.
5、改善瀝青特性
5. Improving asphalt properties
瀝青黏度大，則瀝青流動(dòng)阻力大，噴射成形小，重疊數(shù)減小。為了克服這些不足，一般做法是加大噴嘴通徑，但這樣做勢(shì)必減小了射流速度，弱化了“沖擊一飛濺～勻化”作用，使橫向?yàn)⒉疾痪鶆颉榱颂岣邽r青施工工藝性能，應(yīng)改善瀝青特性。
When the viscosity of asphalt is high, the flow resistance of asphalt is high, the spray forming is small, and the overlap number is reduced. In order to overcome these shortcomings, the general method is to increase the nozzle diameter, but this will certainly reduce the jet velocity, weaken the "impact splash homogenization" effect, and make the lateral distribution uneven. In order to improve the performance of asphalt construction technology, the characteristics of asphalt should be improved.
