Venturi nozzle

Single inlet nozzle:(Venturi nozzle,EnglishVenturi Nozzle)

The structure of the venturi nozzle is divided into three parts: contraction section, straight section and diffusion section, which is difficult to make. The aerodynamic performance of the venturi nozzle is better than that of the straight hole nozzle, the eddy current phenomenon is obviously improved or no longer exists, and the pressure loss is greatly reduced. Under the same pressure condition, the outlet speed of the abrasive can be more than doubled, and the working efficiency is higher than that of the straight hole nozzle. Increases by 15%—40% and reduces abrasive consumption by 20%. The venturi nozzle is generally longer, The venturi nozzle outlet gradually expands the design to make the abrasive initial velocity high and evenly spray on the workpiece surface. This Venturi nozzle with a 1-1/2 inch inlet is widely used in abrasive blasting processes for difficult surfaces.

Double air inlet nozzles(Double Venturi Nozzle):

Consists of two front and rear nozzles. Due to the action of high-speed airflow, a large negative pressure is generated, and the surrounding air is sucked into the nozzles, making the The amount of air ejected is greater than the amount of air sucked in. The blasting area of ​​the double-inlet sandblasting gun is 35% larger than that of the standard single-inlet blasting gun, and the outlet velocity of the blasting medium is approximately reduced. This nozzle is typically used for medium-intensity surface treatment over large areas.
