The composition of the asphalt distributor: it is composed of automobile chassis, asphalt tank, asphalt pump and spraying system, heat transfer oil heating system, combustion system, pneumatic system and circuit system. The hydraulic system of the vehicle is driven by the power take-off. Asphalt spraying is controlled by the electric control and air control system to control the flow rate of the asphalt pump and the opening of the asphalt valve, which is evenly sprayed onto the road surface from the pipeline, after spraying, and nozzle. As the asphalt distributor has a variety of optional configurations, the working principles of different configurations are also different, as follows:
1. The working principle of ordinary asphalt distributor:
As shown in the picture above, because the ordinary asphalt distributor adopts old-fashioned sprinklers, the amount of spraying cannot be adjusted, which is more fuel-intensive, so this ordinary asphalt distributor is used less. PTO→hydraulic pump→asphalt pump hydraulic motor→asphalt pump→spraying (the boom is manually turned on and off, and the cab has a key to start), the type of asphalt sprayed: emulsified asphalt
2. The working principle of the standard asphalt distributor:
As shown in the figure above, the standard asphalt distributor is controlled on the rear working platform, through the power take-off → hydraulic pump → asphalt pump hydraulic motor → asphalt pump → spraying (button operation on the rear working platform, with one-key start in the cab), Therefore, when spraying, a driver is required to drive, and an operator is required to control the rear working platform. The appearance is the same as that of the intelligent type. The types of sprayed asphalt: emulsified asphalt, modified emulsified asphalt, hot asphalt, SBS modified asphalt Wait;
3. The working principle of the intelligent asphalt distributor:
As shown in the figure above, the intelligent asphalt spreader can realize all the spraying operations by one driver in the cab. In-cab computer touch-screen operation ensures accurate spraying of the amount and width of spraying, which means that one operator can be saved. If your sprinkler construction volume is large, it is recommended to choose an intelligent type, because saving one manpower a year can save a lot of money, and the intelligent type sprinkler is not much more expensive than the standard type. Types of sprayed asphalt: emulsified asphalt, modified emulsified asphalt, hot asphalt, SBS modified asphalt, etc.;
4. The working principle of rubber asphalt distributor:
The rubber asphalt distributor adopts imported asphalt pump, add agitator and double burner on the basis of intelligent configuration. We can't distinguish it from the appearance alone. The rubber asphalt distributor is the all-around king among the distributors, which can sprinkle all kinds of asphalt, that is to say, the rubber asphalt distributor can sprinkle rubber asphalt, hot asphalt, emulsified asphalt, etc.
On the basis of intelligent configuration, the rubber asphalt distributor adopts imported asphalt pump, agitator, and dual burners. We can't tell the difference from the appearance alone. The rubber asphalt distributor is the all-around king among the distributors, which can sprinkle all kinds of asphalt, that is to say, the rubber asphalt distributor can sprinkle rubber asphalt, hot asphalt, emulsified asphalt, etc
