Working principle of pressure sand blasting machine The liquid sand blasting machine uses a grinding liquid pump as the power supply of the grinding liquid. The grinding liquid pump sends the evenly mixed grinding liquid (mixture of abrasive and water) into the spray gun. Compressed air, as the acceleration power of the grinding fluid, enters the spray gun through the air pipe. In the spray gun, the compressed air accelerates the grinding fluid entering the spray gun, is ejected through the nozzle, and is sprayed onto the surface to be processed to achieve the intended processing purpose. In the liquid blasting machine, the abrasive pump is used to supply power, and the compressed air is used to accelerate the power. The pressure type blasting machine is different from other sand processing equipment. The blasting machine is a kind of abrasive A sand processing equipment to the surface of the workpiece. According to the characteristics of the sand blasting machine, the sand blasting machine is suitable for cleaning the rough surfaces of forgings, stampings and machined parts, used for the pretreatment process before spraying and electroplating, and strengthening the surface of polished parts. 、 Small parts and small batch production.
Sand blasting machine is characterized by inlet air pressure and sand blasting pressure display, and is equipped with pressure reducing valve, which can adjust the blasting pressure as required. A filter is installed at the compressed air inlet to filter out moisture in the compressed air.
The pressure blasting machine interface chemical analysis instrument also needs to use an optical imaging system for analysis in the application. After all, no matter how advanced a computer system is, you can't directly recognize an image like a human. Therefore, the advancement of optical system design is all the key to the instrument.
Generally, an optical imaging system consists of a lens and a CCD that magnify a certain magnification. The effect of specific imaging can be clearly understood only by looking at actual pictures. The criterion for a good imaging effect is that the image background is clear and does not affect the overall observation. The foreground has good imaging, specific to real sense.
