The uneven distribution of cement spreader is an inevitable problem in the process of using cement spreader. Therefore, our cement spreader taxi rental company has announced the causes and solutions of this problem as follows, so as to facilitate the friends who buy and rent cars to solve such problems in a timely manner and relieve everyone's troubles.
1、 Main reasons for uneven distribution of cement spreader
1. Check whether the asphalt nozzle is loose or blocked;
2. The position of asphalt nozzle is not uniform;
3. The speed is too fast or too slow;
4. The viscosity of asphalt is too high;
5. The height of spraying pipe from the ground is too high or too low.
Solutions for uneven distribution of cement spreader:
1. Clean all asphalt nozzles and check whether there are damaged nozzles and replace them in time;
2. Adjust all asphalt nozzles to the same position;
3. Reduce the speed and control the uniform distribution;
4. The height of spraying pipe from the ground can be adjusted and closed-loop controlled.
As the spray fan angle 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 and adjusted based on it: if the spraying pipe is too high from the ground, 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 overlapping number 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. Improving asphalt properties
When the asphalt viscosity is high, the asphalt flow resistance 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 transverse distribution uneven. In order to improve the performance of asphalt construction technology, asphalt properties should be improved.
