General pressure manual dry sandblasting machine (cart turntable type) - working principle This machine uses suction sandblasting, which uses compressed air to flow at high speed in the nozzle to form negative pressure to produce an ejection effect, and the abrasive in the cyclone separator box It is sucked into the nozzle through the hose, and then sprayed from the nozzle to the surface of the workpiece at high speed with the compressed air flow to achieve the purpose of sandblasting. one. Features of this machine. This machine has novel design, simple and reliable structure, easy operation, good processing efficiency and low energy consumption. .This machine is equipped with an adjustable cyclone separator, which can separate abrasives that can be used again and useless tiny dust. The vacuum cleaner only absorbs dust, so it can greatly reduce the consumption of abrasives. 3. The main parts of this machine are made of high-quality imported parts, which are safe, reliable and have a long service life. two. Scope of use: This machine can clean the rough surfaces of forged castings, welded parts, heat-treated parts, stamping parts and machined parts, remove scale, residual salt and burrs, and is used in pre-treatment processes before spraying and electroplating. This machine is also used to spray glass beads and strengthen the surface of decorative parts. Suitable for single piece and small batch production of medium and small parts. three.

Main technical specifications: Overall dimensions of the host** Working cabin dimensions**3 Separator motor power supply Machine lighting energy-saving lamps Air volume.3/ Working pressure (/) Dust removal method: Equipped with a bag dust removal box, use a foot switch to start pneumatic dust removal The device vibrates for dust removal, and the operator only needs to step on the foot switch to remove dust once or twice every hour. Machine carrying capacity: Machine net weight: 5. Regarding the installation of the machine, the sandblasting machine should be placed on a flat and solid ground at the work site, without anchor bolts. .Use a compressed air hose to connect the compressed air source to the air inlet joint of the sand blasting machine filter pressure regulator valve. Compressed air consumption: (using spray gun nozzle aperture, air nozzle aperture). Compressed air pressure (br) . . . . Compressed air consumption (3/) . . . . Power supply. Insert the power plug of the sandblasting machine into the power socket. The power socket must have a grounding terminal. 3. Operating procedures for loading abrasives: Select appropriate abrasives according to processing needs and load them into the storage box at the bottom of the cyclone separator. The amount of abrasives loaded at one time is about 3-3. Adjustment of compressed air pressure: Adjust the filter pressure valve to control the compressed air pressure entering the nozzle according to work needs. The working pressure can be selected within the range of br. Dust cleaning Clean the dust every hour. The specific operation is: turn off the power switch, step on the dust cleaning foot switch at the left bottom for - minutes to make the dust bag vibrate and shake off the dust, then open the bottom cover of the dust box, and use The container holds the dust and throws it away. Machine operation methods. Turn on the power switch, the light will turn on, and the separator motor will start. B. Open the working cabin, place the parts to be processed on the mesh board, and close the working cabin. Insert work gloves with both hands, hold the spray gun in one hand, grasp the workpiece with the other hand, and aim the spray gun nozzle at the workpiece to be sprayed. ． Press the foot switch lightly to open the compressed air and enter the spray gun. The abrasive will be injected from the bottom of the separator tank into the spray gun according to the set injection volume, and will be sprayed onto the surface of the workpiece to be processed at high speed under the action of the compressed air. ． During the sandblasting process, on the one hand, it is necessary to maintain an appropriate spray distance and angle between the spray gun and the work space; on the other hand, the spray gun and the work space must be moved relative to each other so that the surface of the workpiece is evenly processed by the abrasive spray frame until satisfactory results are achieved. result. ． After the processing is completed, the feet must be removed from the foot switch, and the working hatch can be opened and the parts taken out only after the nozzle stops spraying abrasive. ． If you still need to continue processing parts, do not turn off the separator and lighting power supply in the middle. ． When work is stopped after get off work, the separator and lighting power supply should be turned off.
