This vehicle is easy to operate. On the basis of absorbing various technologies of similar products at home and abroad, it has added the technical content to ensure the quality of construction and the humanized design to highlight the improvement of construction conditions and environment. Its reasonable and reliable design ensures the uniformity of asphalt distribution. The computer control is stable and reliable. The technical performance of the entire vehicle has reached the world's top level. After various improvements by our company, this vehicle can operate under harsher conditions.
Iii. Scope of Application
The product has a wide range of applications and low requirements for environmental conditions. It is suitable for: 1. Highway construction: construction of high-grade pavement base layer, bonding layer and waterproof layer. 2. Maintenance projects: Construction of county and township-level oil roads, asphalt overlay, and layer-by-layer paving techniques. 3. Special purposes: Construction of airport runways, port terminals, reservoirs and other road surfaces.
Iv. Manufacturer Advantages
Products can be customized according to the specific requirements of customers' construction to meet the personalized needs of different construction scenarios and enhance the compatibility of equipment with construction.
When other construction equipment is needed, the full range of products can be rented to save equipment purchase costs and flexibly meet short-term construction demands.
When vehicles are idle, we provide business introductions to help customers make full use of equipment resources and generate additional income.
Second-hand car trade-in and trading address the disposal issues during equipment updates and iterations, ensuring the continuous flow of equipment value.
V. Performance Characteristics and Advantages Description
This vehicle adopts a specially customized chassis for National VI standards, featuring excellent and powerful carrying capacity, flexible and lightweight handling, and a beautiful and elegant appearance design. It provides safe, efficient and reliable services for a wide range of intercity logistics customers.
2. The manual control mode of the post-operation platform can achieve individual control of each group of nozzles, thereby enabling general arbitrary adjustment of the spray width. The lifting and lowering of the spray rod can be adjusted freely through the rear working platform cylinder.
3. The heating system adopts Riello burners, featuring automatic ignition and temperature control functions.
4. With the internationally advanced high-viscosity asphalt pump, the external asphalt can be pumped into the tank to achieve self-priming, and the asphalt inside the tank can be pumped out.
5. The key components of the entire machine (such as hydraulic pumps, hydraulic motors, asphalt pumps, etc.) all adopt internationally renowned parts to ensure the reliability of the entire machine and extend its service life.
6. Under the premise of ensuring that it does not hinder the maintenance and disassembly of other parts, ladders and handrails for each part are arranged to facilitate operation.
7. All heat pipes are equipped with heat insulation layers on the outside, which not only reduces heat dissipation but also prevents scalding of operators.
8. The vehicle-mounted rapid heating system (10-15℃/h) enhances heating efficiency and reduces auxiliary construction time, ensuring the spraying temperature.
9. The asphalt spraying rod adopts a three-section folding structure. By moving the spraying rod up and down, double or multiple sprays can be achieved. By moving the spraying rod left and right, the spraying range can be expanded and obstacles can be effectively avoided.
10. The manual spraying function enables asphalt to be sprayed through the hand spray pipe, which is flexible and convenient, and is suitable for small-scale and corner construction
"Sure. Connect the hand spray gun properly. Open the main oil outlet valve, the switch valve, and the return oil valve. Use the return oil valve to adjust the pressure of the spray gun.
11. The interior of the asphalt tank is equipped with a sedimentation and drainage tank, as well as a liquid level display, alarm and safety devices.
12. Nozzle flushing: This function can blow out the remaining asphalt on the nozzle through the high-pressure air generated by the idling of the asphalt pump, preventing the asphalt from freezing on the nozzle and significantly extending the service life of the nozzle. Close the main oil outlet valve, the return oil valve, open the pneumatic valve, open the self-priming valve, and then open the nozzle in sequence
13. A good insulation layer can ensure that the static insulation performance index is ≤12℃ for 8 hours, and it is anti-corrosive and durable.
14. The outer packaging of this vehicle is made of stainless steel plates, which are anti-corrosive, durable, and elegant.
Vi. Precautions for Equipment Use
When the spreader finishes one operation or changes the construction site, the asphalt pump and pipelines must be cleaned; otherwise, it will not be able to work next time.
2. Before spraying, the sprinkler truck must check whether the positions of all valves are correct.
The hot asphalt added to the asphalt tank must reach a working temperature of 160 to 180 degrees Celsius. For long-distance transportation or prolonged operation, a heating device can be used for insulation, but it cannot be used as an oil melting furnace. Asphalt overflows.
When heating the asphalt inside the tank with a burner, the height of the asphalt must exceed the upper plane of the combustion chamber; otherwise, the combustion chamber will be burned out.
5. If the asphalt pump and pipelines are blocked by solidified asphalt, the pump should not be forcibly rotated. A blowtorch can be used for baking, but direct baking of ball valves and rubber parts should be avoided.
When starting to spray asphalt at the beginning, the vehicle should start slowly and keep a low speed. Do not step hard on the accelerator to prevent damage to components such as the clutch and asphalt pump.
7. At the end of each day's work, if there is any remaining asphalt, it must be returned to the asphalt tank; otherwise, it will solidify in the tank and cannot be used next time. If a vehicle or working device malfunctions and it is determined that it cannot be repaired in a short time, all the asphalt in the tank must be drained completely.
