The asphalt sprinkler is a black pavement construction machinery, which is the main equipment for roads, urban roads, airports, and port pier construction.The equipment mainly sprays different types of asphalt pavement to meet the construction requirements of different levels of pavement layers, adhesive layers, upper and lower seals, and fog block layers.
However, some asphalt spray cars on the market are not satisfactory, and the horizontal uneven spraying phenomenon will occur. The typical horizontal uneven spraying phenomenon is horizontal stripes.At this time, some measures can be taken to effectively improve the horizontal uniformity of asphalt spray.
1. Improve asphalt characteristics
The asphalt viscosity is large, the asphalt flow resistance is large, the spray forming is small, and the overlap is reduced.In order to overcome these deficiencies, the general method is to increase the radius diameter, but this will inevitably reduce the speed of the shot, weaken the effect of "impact one splash ~ uniform", making the horizontal sprinkler uneven.In order to improve the performance of asphalt construction, asphalt characteristics should be improved.
2. Make the spray tube high -level high -level, closed -loop control
Because the spraying fan angle will be affected by factors such as speed, asphalt type, temperature, viscosity, etc., the height of the ground is determined according to construction experience, and it is adjusted as a basis.
3. Improve the nozzle structure
This has the following purpose: First, to adapt to the structure of the spray tube, the distribution of asphalt flow of each nozzle is close to the same;Third, the design requirements for design are to meet the construction requirements of different varieties of asphalt and different sprinkles.
4. Properly increase the speed of sprinkle
As long as the speed of the intelligent asphalt sprinkle is changed within a reasonable range, it has no effect on the asphalt sprinklers vertical uniformity.Because when the speed is faster, the amount of asphalt in the unit time becomes larger, and the amount of asphalt spraying on the unit area remains unchanged, and the speed change of the vehicle has a greater impact on the horizontal uniformity.
