Tungsten Carbide Nozzle Lifespan Improving III

The diameter of nozzle entrance is determined by the flow and pressure. If we narrowing the exit diameter, the pressure and the flow velocity will become greater when the flux is constant so that the sand impact kinetic energy is enhanced and the abrasion of nozzle entrance is severer. Compared with nozzles with different convergent angle, as conical nozzle, the smaller convergent angle, the flow is more stable and the less loss of energy. In addition, lengthen the nozzle appropriately is beneficial for decreasing abrasion, which lengthen the path of the abrasive curve arriving.
