Tungsten Carbide Nozzle Reduce Abrasion Analysis II

Secondly, compared with the acceleration of water flow, the acceleration of abrasive particles is delayed during the movements in nozzle, which depends on the shape of nozzle, the size and density of grinding compound, etc. Due to the turbulence inside nozzle, the grains of grind compound has higher horizontal speed and collides with inner wall of nozzle, which leads to erosion and abrasion.

Therefore, a reasonable shape of inner wall of nozzle plays a significant role in reducing abrasion. There are two normal methods for reducing abrasion. One is to get a small aspect ratio in order to ensure that the entrance before the most badly wore area. And the other is contrary, which is to get a large aspect ratio to ensure that the entrance after the most badly wore area.
