The road maintenance vehicle is a kind of heat preservation and material storage maintenance vehicle. This product adopts diesel burner and electric heating to realize the heating and heat preservation of asphalt mixture. It has many functions, such as road cutting, crushing, emulsified asphalt spraying, discharging, compaction, waste material storage and so on. The operation is convenient. What is the working principle of the asphalt road maintenance vehicle?

Asphalt pavement maintenance vehicle is mainly applicable to the rapid repair of asphalt pavement such as expressway, grade highway, urban road, airport runway, stadium, city square, etc; It can repair and repair pavement potholes, cracks, local aging, looseness, bumps and other diseases with rapid and high-quality thermal regeneration; The road maintenance cost is low, and the effect is remarkable in energy conservation and emission reduction; It has broad market prospects.

The working principle of the asphalt pavement maintenance vehicle is: use the high-pressure water generated by the high-pressure water pump, spray it through the high-pressure nozzle of the water spray frame, use the kinetic energy of the high-pressure water flow, clean it in a high-pressure, low flow way, strong decontamination, efficient water saving, and can clean the old stains on the pavement; Or spray high-pressure water through the left (right) corner to clean the kerb, sidewalk and guardrail isolation area; High pressure spray gun can also be used to clean road signs, billboards, elevated roads, etc; The spray system has powerful functions of spray dust reduction, spraying air disinfectant and adjusting air humidity. The high-pressure water pump is driven by auxiliary engine → reducer → coupling; The low-pressure waterway system adopts a two-stage impeller centrifugal pump, which has high efficiency, large watering width and long range of water gun. It can also be equipped with greening irrigation and self-priming functions. The low-pressure water pump is directly driven by the chassis transmission power take-off through the transmission shaft.

That's all for the introduction of the working principle of asphalt pavement maintenance vehicles. At present, asphalt pavement maintenance vehicles are widely used in the rapid repair and daily maintenance of asphalt pavement pit diseases on expressways, national and provincial trunk lines and municipal roads.
