The uneven distribution of the asphalt distributor trucks is a problem we often encounter in the process of using the asphalt distributor. For this reason, our company specially publishes the cause and solution of this problem as follows, so as to facilitate car buyers to encounter Such problems can be solved in time to relieve everyone’s troubles in using the car.
The main reasons for uneven distribution of asphalt distributor truck:
1. Check whether the asphalt nozzle is loose or blocked;
2. The position of the asphalt nozzle is not uniform;
3. The vehicle speed is too fast or too slow;
4. The asphalt viscosity is too large;
5. The height of the spray pipe from the ground is too high or too low.
Solution to uneven distribution of asphalt distributor truck:
1. Clean up all asphalt nozzles and check if there are damaged nozzles and replace them in time;
2. Adjust all the asphalt nozzles to a uniform position;
3. Reduce the vehicle speed to control the uniform distribution;
4. The height of the spray pipe from the ground can be adjusted and closed-loop control.
Since the spraying fan angle will be affected by factors such as vehicle speed, asphalt type, temperature, viscosity, etc., the ground clearance is best determined based on construction experience, and adjusted based on this: if the spray pipe is too high above the ground, it will reduce asphalt spraying The impact force weakens the effect of “impact-splash ~ homogenization”; if the height of the spray pipe is too low, it will reduce the overlap of the asphalt spraying fan. The height of the spray pipe should be adjusted according to the actual situation to improve the asphalt spraying effect.
5. Improve asphalt characteristics
The higher the asphalt viscosity, the higher the asphalt flow resistance, the smaller the spray forming, and the smaller the number of overlaps. In order to overcome these shortcomings, the general approach is to increase the nozzle diameter, but this will inevitably reduce the jet velocity, weaken the “impact-splash-homogenization” effect, and make the lateral spreading uneven. In order to improve the performance of asphalt construction process, the characteristics of asphalt should be improved.
