摘要

用于磨料喷射加工的喷射清洁装置有多种实际应用。工作喷嘴是影响加工表面质量的关键设备之一。因此,有必要采用新的方法来提高磨料喷射设备喷嘴的效率,即改进喷嘴的设计,并进一步开发一种新的、相对廉价但有效的喷嘴制造和维护技术。这种技术应能使喷嘴具有较高的耐用性,而对制造材料的硬度或耐磨性参数并无要求。喷嘴应设计成一个长条形穿孔插件,以允许径向气流,迫使研磨材料(河沙)从喷嘴工作面的内壁流出,从而减少与研磨材料的摩擦。这将产生新的磨损条件,从根本上减少喷嘴工作面的磨损。本文旨在根据穿孔插件的应用,为工作喷嘴开发一种更有效的设计。其任务是对穿孔喷嘴的加工过程进行更详细的实验和理论研究,以提高其有效性。研究的结果是设计出了效率更高的新喷嘴。

Ensuring the Abrasive Jet Machining Efficiency Using a Nozzle with a Perforated Insert
Ejector-cleaning devices for abrasive jet machining have various practical applications. The working nozzle is one of the device’s key elements affecting the treated surface quality. There arises the necessity for new approaches to achieving an efficiency increase in abrasive jet equipment nozzles, namely their design improvement and further development of a new, relatively cheap but effective technology for their manufacturing and maintenance. This technology should allow for the high durability of nozzles without being essential for the hardness or wear resistance parameters of the material used for manufacturing. The nozzle should be designed as a long-length perforated insert to allow for radial airflow, forcing the abrasive material (river sand) from the inner walls of the nozzle’s working surface to reduce its friction with the abrasive material. This will result in new wear-out conditions, providing an essential decrease in the wear-out of a nozzle’s working surface. The article aims to develop a more effective design for the working nozzle based on the perforated insert application. The task was set to provide a more detailed experimental and theoretical study of the processes in perforated nozzles to improve their effectiveness. The research resulted in a new design for nozzles with higher efficiency.
