1·The changing of detailed structure of diesel nozzle tip greatly affect the flow characteristics in the nozzle hole and the performance of the following breakup of spray.
柴油机喷嘴头部细微结构的变化对内部流动有显著的影响，进而影响到喷雾油束雾化性能。
2·Runner plate design with balanced and stable runner as well as even heat distribution: open hot runner nozzle tip for high temperature and high wear-resisting engineering plastics;
流道平衡稳定、热量分布均匀的流道板设计； 针对高温高耐磨工程塑料的开放式热流道喷嘴嘴尖；
3·The hollow-axis motor drives the offset nozzle and rotates the arc on the tip of wire at high speed, so as to ensure enough penetration into the sidewalls in narrow gap welding.
在该系统中，焊丝穿过电机的空心轴后从导电嘴的偏心孔送出，电机带动导电杆和偏心导电嘴旋转，从而使焊丝端部的电弧以一定直径高速旋转，以保证窄间隙焊接接头具有足够的侧壁熔深。
4·The relationship model of static head in tundish, atomization pressure on the tip of nozzle and the mass median droplet diameter was established.
本文建立了静压头、雾化压力与雾化熔滴尺寸的模型关系。
