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.
The main reasons for uneven distribution of cement spreader are as follows
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.
Solution to uneven distribution of cement spreader
1. Clean all asphalt nozzles, check whether there are damaged nozzles and replace them in time;
2. Adjust all the asphalt nozzles to the same position;
3. Reduce the speed and control the uniform distribution;
4. The height of the spraying pipe from the ground can be adjusted and controlled in closed loop.
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. Improving asphalt properties
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.
