High Pressure Sandblasting Gun Head

The High Pressure Sandblasting Gun Head is divided into two types: an extrusion type sandblasting gun (commonly known as a high pressure sandblasting gun head) and a suction type sandblasting gun (commonly known as a general pressure sandblasting gun head). In terms of materials, sandblasting guns are classified into boron carbide, alloy steel, tungsten carbide, and iron. The most durable is a boron carbide blasting gun with a service life of 500-700 hours.

The compressed air is used as the power, and the working pressure established in the pressure tank by the compressed air is pressed into the sand pipe through the sand discharging valve and injected through the sandblasting gun, and sprayed onto the surface to be processed to achieve the desired processing purpose. In high-pressure blasting gun heads, compressed air is both the propulsion power and the acceleration power of the jet.
The high-pressure blasting guns are roughly divided into two types: a double-intake blasting gun and a smashing wind blasting gun. The single-inlet air is a straight tube, and the structure is a venturi type.

The double inlet air is divided into two sections, and there are 8 small openings in the middle, which play the role of secondary air intake. In this large and small, one-to-one nozzle arrangement, due to the action of high-speed airflow, an adequate The large negative pressure draws the surrounding air into the nozzle, so that the amount of air ejected is larger than the compressed air entering the nozzle, and the exit speed of the abrasive is increased. In addition, the diameter of the outlet of the double inlet blasting gun is smaller than that of the single inlet. Larger, the divergence surface of the abrasive stream is 30% larger than the single inlet air, and the blasting efficiency is higher.
