Influencing Factors Of Sand Blasting Machine

Dec. 18, 2018

The Sand Blasting Machine uses the compressed air to flow at a high speed in the spray gun to form a negative pressure to generate an ejector. The abrasive in the cyclone storage tank is sucked into the spray gun through the sand tube, and then is sprayed by the nozzle to the surface of the workpiece at high speed with the flow of compressed air. Achieve the purpose of sandblasting. In the working state, the compressed air and the sand material are mixed while being sprayed, so that the compressed air is fully utilized, the flow rate of the air and the flow rate of the sand material are easily adjusted, the ideal mixing ratio can be obtained, the energy and the sand material are consumed less, and the cleaning efficiency is high. .

Influencing factors of various aspects of Flour Sand Blasting Machine:

1. Influence of abrasive type on surface results

Abrasives are divided into spherical and diamond-shaped according to the state of the particles. The diamonds (white steel jade and brown corundum) usually used for sand blasting are diamond-shaped abrasives. The glass beads are spherical abrasives. After the three values of P, H and θ are set, the surface obtained by spherical abrasive blasting is smoother, the surface obtained by the diamond abrasive is relatively rough, and the same abrasive has the thickness.

2. The effect of the adjustment of the pressure on the surface results

After the three quantities of S, H, and θ are set, the higher the P value, the higher the velocity of the jet, the higher the blasting efficiency, and the rougher the surface of the workpiece, and conversely, the surface is relatively smooth.

3. The influence of the distance and angle of the spray gun on the surface results

After the P and S values are set, this is the key to the manual sand blasting technology. The spray gun is generally 50 to 150 mm from the workpiece. The farther the spray gun is from the workpiece, the lower the efficiency of the jet flow and the smoother the surface of the workpiece. The smaller the angle between the spray gun and the workpiece, the lower the efficiency of the jet and the smoother the surface of the workpiece.
