徐工针对预防性养护新工艺——超薄磨耗层施工特点而研发、可实现乳化沥青洒布与沥青混合料摊铺同步作业的一体化施工设备。采用自主研发的脉冲喷洒控制技术,借鉴喷墨打印原理,通过喷洒杆分段布置和多喷头独立控制,可实现高精度定量喷洒和优异的洒布均匀性,同时可实现自动齐缝、喷洒量随摊铺速度和宽度自动匹配等功能。采用负载敏感液压驱动系统及压力传感技术,通过闭环控制使乳化沥青管路保持恒压,实现喷头喷洒流量
XCMG aimed at the preventive maintenance of new technology - the characteristics of ultra-thin wear layer research and development, emulsified asphalt spreading and asphalt paving operation can be achieved simultaneously integrated construction equipment. Using independent research and development of pulse spraying control technology, drawing on the principle of inkjet printing, the spraying rod segment arrangement and multi-nozzle independent control can realize high-precision quantitative spraying and excellent uniformity of spraying, With paving speed and width automatically match other functions. Load-sensitive hydraulic drive system and pressure sensing technology, the closed-loop control of the asphalt emulsion to maintain constant pressure to achieve nozzle spray flow
