Sand blasting machines are the category of air conveying machinery. The compressed air is used to transport the powdery particles (1~4mm in diameter) from one place to another in the pipeline. During the process of converting kinetic energy into potential energy, the high-speed moving sand particles wash the surface of the object to improve the surface of the object. Quality effect

Sand blasting machines are the category of air conveying machinery. The compressed air is used to transport the powdery particles (1~4mm in diameter) from one place to another in the pipeline. During the process of converting kinetic energy into potential energy, the high-speed moving sand particles wash the surface of the object to improve the surface of the object. Quality effect


principle:

The sand is pushed forward by the compressed air in the pipeline and appears in two states: suspension and pulsation.


The ideal working condition requirement is that the sand has a uniform floating flow state in the pipeline. The appropriate sand amount and the appropriate air volume and wind pressure are the most important factors determining the flow effect of the sand. The air volume should be such that the air flow rate in the pipeline At least greater than the sedimentation velocity of the largest particle of sand, the wind pressure is sufficient to overcome the friction loss and resistance of the air in the pipeline to promote the flow of sand, so as to ensure the smooth flow of sand in the pipeline.


However, as the pipeline grows, the wind pressure gradually decreases, the airflow velocity decreases, and the suspended particles first appear non-uniformly suspended flow, and then the uneven flow state occurs. When the air velocity is less than a certain value, a pulsating flow state occurs. As the airflow speed is further reduced, a part of the material particles will stagnate at the bottom of the pipeline, and the other part will slide forward to move, thereby causing the stagnant material layer to move unsteadily, and finally forming a blockage, resulting in work failure. This is what the blasting process seeks to avoid [1].


Due to the impact of the abrasive on the surface of the workpiece and the cutting action, the surface of the workpiece obtains a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece are improved, thereby improving the fatigue resistance of the workpiece and increasing it. The adhesion between the coating and the coating prolongs the durability of the coating film, and also facilitates the leveling and decoration of the coating, removes impurities, mottling and oxide layers on the surface, and at the same time roughens the surface of the medium to eliminate residual stress of the workpiece. And the effect of increasing the surface hardness of the substrate.


The main purpose

Sandblasting is an extremely widely used process in mechanical manufacturing. Parts for forging, casting, heat treatment and surface treatment must be sandblasted to remove oxide scale, sand, old coating and molten salt heat. Corrosion, etc.
