Venturi Nozzle
Gas dynamic of single venturi nozzle is better than straight-hole nozzle, the vortex is improved or ceased to exist, greatly reduced the pressure loss in the same pressure conditions. Abrasive exports increased to more than double the speed, efficiency than the straight-hole nozzle to increase 15% -40%, 20% lower abrasive consumption.
Double venturi nozzles offers a 35% larger blast pattern than a standard long venture with only a very slight loss in abrasive velocity. Designed to be used on jobs where medium cutting action is required with a more even dIspersion of abrasive throughout the larger blast pattern. Excellent for plastic or agricultural abrasives.
Straight Bore Nozzles
1.Density:2.48g/cm3
2.Outter dia:6-110mm; Inner dia:3.2-90mm
3.Length:20-330mm
Straight hole nozzle has the characteristics of a simple structure, only with the converging section and straight section. However, this kind of nozzle also has the problem of the vortex
at the entry area, high pressure loss and low outlet velocity, as lower as 50% of Venturi nozzle.
Straight hole nozzle is usurally used withinthe sand-blasting machines,which have low sprayintensity and narrow closed struture.
