Cement spreader refers to the tank type special operation vehicle equipped with thermal insulation container, asphalt pump, heater and spraying system, which is used to spray asphalt; it can also be defined as a kind of pavement construction machinery for spraying liquid asphalt such as hot asphalt, emulsified asphalt and residual oil; it can be widely used in road construction, urban road construction, airport construction, port terminal construction and reservoir construction.

　　水泥撒布车工作原理：

　　Working principle of cement spreader:

　　首先加入施工需要的沥青，启动燃烧加热系统，通过导热油循环进行加热，保温可进行作业。根据喷洒量计算施工车速进行车速标定，计算沥青泵转速摸拟控制操作。校对完毕。沥青泵沥青管道按照小循环方式工作，设定喷洒宽度和沥青泵转速。打开喷头架并提升至适合的施工高度，将沥青循环系统由小循环转入大循环。启动喷洒总控开关，沥青从喷头架喷出，工作区域完成时关闭喷洒总控。沥青喷洒停止，合拢喷头架，沥青管道进行清洗，完成工作。

　　Firstly, asphalt needed for construction is added, and the combustion heating system is started. The heat transfer oil circulation is used for heating, and the insulation can be carried out. According to the spraying amount, calculate the construction speed, calibrate the speed, calculate the speed of the asphalt pump, and simulate the control operation. The proofreading is finished. The asphalt pipeline of asphalt pump works in small circulation mode, and the spraying width and speed of asphalt pump are set. Open the sprinkler frame and lift it to the suitable construction height, and transfer the asphalt circulation system from small circulation to large circulation. Start the spraying master control switch, spray asphalt from the sprinkler rack, and turn off the spraying master control when the working area is completed. Stop the asphalt spraying, close the nozzle frame, clean the asphalt pipeline, and complete the work.
