As the accelerating power of grinding fluid, compressed air passes through the nozzle of gas transmission pipe. In the nozzle, compressed air accelerates the grinding fluid of the nozzle, and passes through the nozzle to the processed surface to achieve the expected processing purpose. In the liquid sand blasting machine, the grinding liquid pump is the feeding power, and the compressed air is the main purpose of accelerating the power sand blasting machine.

Finishing and strengthening the external appearance of parts; Finishing and strengthening of tools, fixtures and materials; Surface finishing of parts before electroplating, oxidation and coating; Remove pollutants on the surface of barrels, tubes, plates, cans and utensils; Sorting of tools, molds, pipes, plates and operating parts; Surface finishing of glass mold, rubber mold, metal casting and extrusion; Repair welds; Surface glaze of workpiece; Remove the oxide scale on the surface of the workpiece and the color difference during and after processing (castings and forgings).

Manual derusting and sand blasting machine is generally divided into box type manual derusting and sand blasting machine and mobile open type manual derusting and sand blasting machine. Box type manual derusting and sand blasting machine generally adopts sand blasting method. The operation principle uses abrasive and gas to impact and cut the surface of the workpiece. The open manual derusting sand blasting machine adopts the pressurized sand blasting method.

Dalian sanding and derusting round pipe outer wall automatic sandblasting machine the special sandblasting machine for pipe outer wall cleaning is a customized sandblasting machine. It is designed with 12 nozzles and equipped with bag type dust removal box. It uses pneumatic automatic / manual dust removal. The sandblasting products need to be driven by the rotating shaft to obtain a uniform sandblasting surface. The utility model is composed of a speed reducing motor, etc., which has stable operation, high sand blasting efficiency and good effect. It is widely used in the sand blasting treatment of round pipe fittings such as selenium drum, metal pipe fittings, glass rod fittings and glass pipe fittings.

Traditional sanding process and equipment are widely used in the treatment of base materials and flat furniture, most of which are inseparable from people's participation. However, for special-shaped solid wood furniture or solid wood carved furniture, its treatment will be more time-consuming and laborious. Even the traditional special-shaped sanding machine can only deal with 70% of the covering surface, and manual post-treatment is also required. Due to the high degree of manual participation in the traditional sanding process, it is easy to have problems in the details in the long run. For example, when polishing the wood door finish, it is easy to wear edges and corners due to uneven strength, and there are serious sand marks when breaking the film.
