The reason why the sandblasting machine sandblasting surface density is inconsistent
In the use of sand blasting machine, if the density of sand surface is inconsistent, it is likely to be caused by internal failure of the equipment, so we need to find out the cause of the problem in time, so as to solve the problem reasonably and ensure the use of the equipment.(1) Sandblasting equipment in sandblasting gun walking speed is not stable. When the speed of the spray gun is slow and that of the spray gun is fast, the sand emitted by the two is the same per unit time, but the distribution area of the sand is small in the former and large in the latter. Because the same amount of sand is distributed on the surface of different areas, it is inevitable to appear dense and inconsistent phenomenon.
(2) The air pressure of sandblasting machine is unstable in the process of operation. When an air compressor is used for multiple spray guns, the air pressure is more difficult to stabilize, when the air pressure is high, the sand is more inhaled and ejected, and when the air pressure is low, it is the opposite, that is, the amount of sand inhaled and ejected is less. When the amount of sand is much, the sand surface is bound to appear dense, while when the amount of sand is little, the sand surface is bound to be sparse.
(3) The nozzle distance from the surface of the workpiece is too close and far. When the nozzle of the spray gun is close to the surface of the parts, the spray range is small, but it is more concentrated and dense. When the nozzle of the spray gun is far from the surface of the parts, the sand is still sprayed so much, but the sprayed area is expanded, and it will appear sparse.
The above is the reason for the inconsistent density of the sand surface of the sand blasting machine. According to the introduction, we can better distinguish the problem, so as to solve the problem quickly and ensure the use efficiency of the equipment.
