The complete composition of an asphalt distributor truck:
The intelligent asphalt distributor truck consists of a chassis, asphalt tank, asphalt pumping and spraying system, heat transfer oil heating system, hydraulic system, combustion system, control system, pneumatic system, and operating platform.
(1) Asphalt Tank
It consists of an inner liner, insulation material, outer shell, baffles, combustion chamber, asphalt pipes inside the tank, heat transfer oil pipes, air tank, filler neck, volumetric gauge, and decorative panels. The tank is an elliptical cylinder, with two layers welded from steel plates, filled with aluminum silicate insulation material (50-100mm thick) between the two layers, and covered with stainless steel plates. There is a trough at the bottom to facilitate the absorption of asphalt from the tank. Five mounting feet at the bottom of the tank are welded to the sub-beam and then fixed to the chassis. The outer layer of the combustion chamber is the heat transfer oil heating chamber, with a row of heat transfer oil heating pipes at the bottom. The volumetric gauge indicates the level of asphalt in the tank.
(2) Power Transmission System
It consists of a power take-off and pump drive device, hydraulic system, etc. Generally, a power take-off (PTO) mounted on the chassis engine or transmission output port drives the hydraulic pump, providing the necessary power for the asphalt spraying device. The hydraulic system consists of a hydraulic pump, overflow valve, directional valve, hydraulic motor, and hydraulic pipelines.
(3) Asphalt Pump and Piping System
This system consists of an asphalt pump, filter, valves, spraying pipelines, and cylinder nozzle assemblies. Different combinations of valves control the flow direction of liquid asphalt in the pipeline. Its main functions include: self-priming asphalt filling, rear-pipe spraying, hand-held spraying, circulation, back suction, and cleaning.
(4) Asphalt Heating and Heat Transfer Oil System
This system consists of a combustion heating system and a heat transfer oil circulation heating system.
(5) Asphalt Pipeline Cleaning System
This system has two parts: diesel cleaning and high-pressure air flushing. The diesel cleaning part consists of a diesel tank, inlet copper ball valve, and pipelines. The high-pressure air flushing part consists of an air tank, check valve, and air valve.
(6) Electrical and Control System
The electrical control system consists of two parts: DC circuits and AC circuits. The DC circuit consists of a power take-off, reducer, cooler, hydraulic reversing valve, rear nozzle lifting, rear work light control circuit, and automatic control system circuit; the AC circuit consists of a generator, burner, and heat transfer oil motor circuit.
