摘要： A nozzle and method for mixing abrasive particles with a stream of water and focusing the mixture of abrasive and water exiting the nozzle to improve the ability of the stream to remove paint and other coatings, rust, and scale and the like from a surface for use in operations such as metal finishing. The nozzle includes a spindle that rotates in a housing, the spindle including a chamber in which water passing through a passage in the spindle is mixed with abrasive particles. The passage through the spindle includes a section that is substantially coincident with the rotational axis of the spindle and a section that is angled relative to the section that is coincident with the rotational axis of the spindle, the mixing chamber being located in the off-axis section of and in fluid communication with the passage through the spindle. The mixture of abrasive and water then exits the nozzle from a focal tube that is also located in the angled section of the passage through the spindle such that the mixed water and abrasive defines a circular pattern that maintains the ability to finish the metal while widening the spray pattern, thereby improving the quality and speed of the metal finishing operation.
摘要翻译：一种用于将磨料颗粒与水流混合并将离开喷嘴的研磨剂和水的混合物聚焦的喷嘴和方法，以提高流从表面去除涂料和其它涂层，锈蚀和水垢等的能力在金属加工等操作中。喷嘴包括在壳体中旋转的主轴，所述主轴包括室，其中通过主轴中的通道的水与磨料颗粒混合。通过主轴的通道包括与主轴的旋转轴线基本重合的部分和相对于与主轴的旋转轴线重合的部分成角度的部分，混合室位于离轴并且与通过主轴的通道流体连通。研磨剂和水的混合物然后从焦点管离开喷嘴，焦点管也位于通过主轴的通道的成角度部分中，使得混合水和研磨剂限定圆形图案，其保持完成金属的能力，同时加宽喷涂图案，从而提高金属精加工的质量和速度。
