　　Principle of standard cement slurry spraying truck

　　标准水泥净浆洒布车原理智能型沥青洒布车由汽车底盘、沥青罐体、沥青泵送及喷洒系统、导热油加热系统、液压系统、燃烧系统、控制系统、气动系统、操作平台构成。。怎么计算沥青洒布车的洒布高度和精度？下面一起来了解下吧！

　　The principle of the standard cement slurry spraying truck is that the intelligent asphalt spraying truck consists of a vehicle chassis, asphalt tank body, asphalt pumping and spraying system, thermal oil heating system, hydraulic system, combustion system, control system, pneumatic system, and operating platform.. How to calculate the spraying height and accuracy of an asphalt distributor truck? Let's learn about it together below!

　　后双桥同步碎石封层车采用电气控制，自动化程度高，，能的计算出设备在施工过程中沥青喷洒量和石屑撒布量的多少；按照移动方式，可分为拖行式（挂车式）和自行式2种。拖行式是将沥青罐和洒布系统都装置在挂车底盘上，由牵引车牵引作业；根据沥青罐容量不同，有单轴、双轴和三轴之分。自行式是将沥青罐及洒布系统安装在同一汽车底盘上，是常用的一种，又有车载型、专用型之分。上述沥青洒布车具有加热、保温、洒布、回收及循环等多种功能，可根据底盘*大载重质量确定沥青罐容量。沥青罐容量一般在1500～18000 L范围。

　　The synchronous gravel sealing vehicle for the rear double bridge adopts electrical control, with a high degree of automation, and can calculate the amount of asphalt spraying and stone chip spreading during the construction process of the equipment; According to the mode of movement, it can be divided into two types: trailer type and self-propelled type. Trailer type refers to the installation of asphalt tanks and spraying systems on the trailer chassis, which are operated by a tractor; According to the different capacities of asphalt tanks, they can be classified into single axis, double axis, and three-axis. Self propelled is a commonly used type that installs asphalt tanks and spraying systems on the same vehicle chassis, and can be divided into vehicle mounted and specialized types. The above-mentioned asphalt distributor truck has multiple functions such as heating, insulation, spraying, recycling, and circulation. The capacity of the asphalt tank can be determined based on the weight of the chassis and the maximum load capacity. The capacity of asphalt tanks is generally in the range of 1500 to 18000 L.

　　液压部分采用品牌的元件(液压泵，液压马达)，保证传动性能的可靠按照沥青泵驱动方式，可分为汽车底盘发动机取力驱动和独立发动机驱动2种；

　　The hydraulic part adopts branded components (hydraulic pump, hydraulic motor) to ensure reliable transmission performance. According to the asphalt pump drive method, it can be divided into two types: automotive chassis engine power take-off drive and independent engine drive;

　　沥青泵及管道系统：由沥青泵、过滤器、阀门、喷洒管路、汽缸喷嘴组件等组成。通过阀门的不同组合来控制液态沥青在管道中的流动方向，主要功能如下：自吸加注沥青、后排管喷洒、手提喷管喷洒、循环、回吸、清洗等。相邻的石材接缝必须对齐，缝宽1CM，检查后缝隙要及时补齐。

　　Asphalt pump and pipeline system: composed of asphalt pump, filter, valve, spray pipeline, cylinder nozzle components, etc. By using different combinations of valves to control the flow direction of liquid asphalt in pipelines, the main functions are as follows: self-priming asphalt injection, rear pipe spraying, handheld nozzle spraying, circulation, suction, cleaning, etc. The adjacent stone joints must be aligned with a width of 1cm, and the gaps should be promptly filled after inspection.

　　6方、8方、13方沥青洒布车，沥青洒布车喷洒热沥青注意事项

　　6 square, 8 square, and 13 square asphalt distribution trucks, precautions for spraying hot asphalt with asphalt distribution trucks

　　1、加入热沥青前，罐体内绝不允许有水存在，否则将发生危险。

　　1. Before adding hot asphalt, there must be no water in the tank, otherwise danger may occur.

　　2、导热油温度不能超过280℃。变量泵、沥青泵、导热油泵、液压马达、导热油马达、导热油阀门、导热油过滤器、液压油过滤器、沥青旋转接头、导热油旋转接头电磁阀、换向阀、流量分配阀逆变器、编码器、温度表、转速表、减速机、压力表、铜球阀、雷达、提升气缸、碎石气缸、喷嘴气缸、传感器、燃烧器、液位计、侧位浮球开关、气管、接头、电气元件……等均为国外知名品牌3、喷洒结束，一定要清洗沥青泵和管道。

　　2. The temperature of the heat transfer oil cannot exceed 280 ℃. Variable displacement pumps, asphalt pumps, heat transfer oil pumps, hydraulic motors, heat transfer oil motors, heat transfer oil valves, heat transfer oil filters, hydraulic oil filters, asphalt rotary joints, heat transfer oil rotary joint solenoid valves, directional valves, flow distribution valve inverters, encoders, thermometers, tachometers, reducers, pressure gauges, copper ball valves, radars, lifting cylinders, gravel cylinders, nozzle cylinders, sensors, burners, liquid level gauges, side float switches, air pipes, joints, electrical components, etc. are all well-known foreign brands. 3. After spraying, be sure to clean the asphalt pump and pipelines.

　　4、罐体内剩余沥青必须放尽（包括沉槽）。

　　4. The remaining asphalt in the tank must be emptied (including the settling tank).

　　5、新车行驶2500KM以内，必须到汽车底盘特约维修站做“走保”否则不予三包。

　　5. If the new car travels within 2500KM, it must go to a designated chassis repair station for "maintenance", otherwise it will not be covered by the three guarantees.

　　6、准备在使用热沥青后转换为使用乳化沥青，必须将沥青泵、管道、阀门，罐体内的沥青全部清理干净，否则无法使用。沥青泵及管道系统：由沥青泵、过滤器、阀门、喷洒管路、汽缸喷嘴组件等组成。通过阀门的不同组合来控制液态沥青在管道中的流动方向，主要功能如下：自吸加注沥青、后排管喷洒、手提喷管喷洒、循环、回吸、清洗等。

　　6. To switch from using hot asphalt to using emulsified asphalt, it is necessary to clean all the asphalt in the asphalt pump, pipeline, valve, and tank body, otherwise it cannot be used. Asphalt pump and pipeline system: composed of asphalt pump, filter, valve, spray pipeline, cylinder nozzle components, etc. By using different combinations of valves to control the flow direction of liquid asphalt in pipelines, the main functions are as follows: self-priming asphalt injection, rear pipe spraying, handheld nozzle spraying, circulation, suction, cleaning, etc.
