1. Equipment usage and brief introduction
CLW5250GLQZ asphalt distributor is a kind of intelligent automatic high-tech product that professionally distributes emulsified asphalt, diluted asphalt, hot asphalt, high viscosity modified asphalt, etc. It is used to spread the permeable oil, waterproof layer and adhesive layer of the bottom layer of asphalt pavement for high-grade highways. The distributor is composed of an automobile chassis, an asphalt tank, an asphalt pumping and spraying system, a heat conduction oil heating system, a hydraulic system, a combustion system, a control system, a pneumatic system, and an operating platform. The truck is easy to operate. On the basis of absorbing various technologies of similar products at home and abroad, it has added a humanized design that ensures the quality of construction and highlights the improvement of construction conditions and construction environment. Its reasonable and reliable design ensures the uniformity of asphalt distribution, computer control is stable and reliable, and the technical performance of the vehicle has reached the world’s advanced level. The truck can work under harsher conditions after all aspects of our company’s improvement

◆ Equipment performance characteristics
1. The truck adopts the chassis of China Euro Heavy Duty Truck, and the original full-power power take-off of the chassis guarantees the zero-start work of the equipment; excellent and powerful truck rying capacity, flexible and light maneuverability, and beautiful and atmospheric appearance, providing the majority of intercity logistics customers Safe, efficient and reliable service;
2. According to the needs of spraying volume and working width, the computer can truck ry out any combination of row nozzles;
3 Both manual and automatic control modes can realize the individual control of each nozzle, thus realizing arbitrary adjustment of the spraying width.
4 Asphalt distribution control can be done not only in the cab, but also on the operating platform at the rear of the vehicle;
5 The automatic control system of the vehicle can measure the speed of the vehicle and automatically calculate the rotation speed of the asphalt pump according to the input spreading amount, spraying width and asphalt type, and then automatically adjust the number of asphalt pumps through the system.
6 The heating system adopts imported Italian burners with automatic ignition and temperature control functions;
7 The inter Euro advanced imported high-viscosity asphalt pump can be used to pump the external asphalt into the tank to achieve “self-priming” and also pump the asphalt out of the tank;
8 Parts of key parts of the whole machine (such as German Rexroth hydraulic pump A11V040EP20D-10L, hydraulic motor 05-130-BD31, Belgian asphalt pump TGGP125-185, proportional valve EFBG-03-160-HF, German Siemens original control system CLW- 48-01, etc.) adopt inter Euro ly renowned components to ensure the reliability of the whole machine and increase the service life;
9 Under the premise of ensuring that the maintenance and disassembly of other parts are not hindered, each part of the ladder and handrails are arranged for easy operation;
10 All heat pipes are equipped with a thermal insulation layer outside to reduce heat dissipation and avoid scalding operators;
11 Vehicle-mounted rapid heating system (10-15℃/h), which can improve heating efficiency and reduce construction auxiliary time to ensure spreading temperature;
12 Asphalt spraying rod adopts a three-stage folding structure, double or multiple spraying can be realized by moving the spraying rod up and down, and the spraying range can be expanded by moving the spraying rod left and right, and obstacles can be effectively avoided;
13 The manual spraying function allows the asphalt to be sprayed through the hand nozzle, which is flexible and convenient, and is suitable for small areas and corner construction conditions. Connect the hand spray gun. Open the main oil valve, open the transfer valve, open the oil return valve, and use the oil return valve to adjust the pressure of the spray gun.
14 The asphalt tank is equipped with a sedimentation drain, and is equipped with a liquid level display, alarm and safety devices;
15-stroke nozzle This function can blow the remaining bitumen from the nozzle through diesel fuel and high-pressure air to prevent the bitumen from freezing on the nozzle, which can greatly improve the service life of the nozzle. Close the main oil valve, return valve, open the pneumatic valve, open the self-priming valve and open the nozzle in turn
16 A good insulation layer can ensure that the static insulation performance index is ≤12℃/8 hours, and it is anti-corrosive and durable;
17 The outer packaging of the truck is made of stainless steel plate, which is anti-corrosive, durable and beautiful.
3. Matters needing attention when using the equipment
1. The asphalt pump and pipeline must be cleaned when the spreader truck finishes one operation or changes the construction site, otherwise it will not work next time.
2. Before spraying, the distributor must check whether the valve positions are correct.
The hot bitumen added into the bitumen tank must reach a working temperature of 160~180℃. For long-distance transportation or working time is too long, a heating device can be used for heat preservation, but it cannot be used as an oil melting furnace.
3. The asphalt tank cannot be filled too full, and the fuel filler cap must be closed tightly to prevent the asphalt from overflowing during transportation.
4. When using a burner to heat the asphalt in the tank, the asphalt height must exceed the upper plane of the combustion chamber, otherwise the combustion chamber will be burned out.
5. If the asphalt pump and pipeline are blocked by the solidified asphalt, the pump can not be forced to rotate, but a blowtorch can be used for baking. Avoid directly baking ball valves and rubber parts.
6. When spraying asphalt at first, start slowly and keep the truck running at a low speed. Do not slam on the accelerator to prevent damage to the clutch, asphalt pump and other components.
7. This truck has two front and rear consoles. When using the front console, switch to the front control. At this time, the rear console can only control the lifting of the nozzle. When using the rear console, you need to turn the switch to the rear control. At this time, the front console has no effect. In addition, each small nozzle switch can be used to open and close the rear console.
8. After the daily operation is completed, if there is remaining asphalt, it must be returned to the asphalt pool, otherwise it will not work next time if it solidifies in the tank. If the truck or working device fails and it is determined that it cannot be repaired in a short time, the asphalt in the tank must be drained.
