水泥撒布车洒布不均匀是我们在使用水泥撒布车过程中经常会遇到的问题，为此问题的引起的原因和解决方法公布如下，以方便购车朋友在遇到此类问题时能及时解决，解除大家用车中的烦恼。
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.
水泥撒布车洒布不均匀的主要原因：
The main reasons for uneven distribution of cement spreader are as follows
1.检查沥青喷嘴是否松动或者有堵住的现象；
1. Check whether the asphalt nozzle is loose or blocked;
2.沥青喷嘴位置不统一；
2. The position of asphalt nozzle is not uniform;
3.车速过快或者过慢；
3. The speed is too fast or too slow;
4.沥青粘度过大；
4. The viscosity of asphalt is too high;
5.喷洒管离地高度过高或者过低。
5. The height of spraying pipe from the ground is too high or too low.
水泥撒布车洒布不均匀的解决方法：
Solution to uneven distribution of cement spreader
1.清理全部沥青喷嘴检查是否有损坏的喷嘴及时更换；
1. Clean all asphalt nozzles, check whether there are damaged nozzles and replace them in time;
2.把沥青喷嘴全部调整到统一位置；
2. Adjust all the asphalt nozzles to the same position;
3.降低车速控制均码洒布；
3. Reduce the speed and control the uniform distribution;
4、使喷洒管离地高度可调，闭环控制。
4. The height of the spraying pipe from the ground can be adjusted and controlled in closed loop.
由于喷洒扇面角会受到车速、沥青种类、温度、粘度等因素影响，所以离地高度尽量根据施工经验确定，并以此作为依据进行调整：喷洒管离地高度太大，会减小沥青喷洒冲击力，弱化“冲击一飞溅～匀化”作用；喷洒管离地高度过低，会减小沥青喷洒扇面重叠数，应根据实际情况调节喷洒管高度以提高沥青喷洒效果。
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、改善沥青特性
5. Improving asphalt properties
沥青黏度大，则沥青流动阻力大，喷射成形小，重叠数减小。为了克服这些不足，一般做法是加大喷嘴通径，但这样做势必减小了射流速度，弱化了“冲击一飞溅～匀化”作用，使横向洒布不均匀。为了提高沥青施工工艺性能，应改善沥青特性。
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.
