The open sand blasting machine is widely used in the surface derusting and appearance strengthening of steel structures in industries such as machinery, ships, bridges, railways, oil pipelines, boilers and ports, etc., as well as external sculptures and sprays of leather, clothing, glass, stone, etc. Decorative treatment. If equipped with an inner wall blaster, the GP series sand blasting machine can be sandblasted on the inner wall of the pipeline by open blasting.
1. Pre-use preparation and inspection equipment and equipped with abrasive, tapered closure valve (3 pieces on top, the whole working principle: compressed air through the bamboo joints (parts 7 into the sandblast pressure tank. Pressure tank sealed. The abrasive in the pressure tank flows into the sand valve (item 12 compressed air is mixed with the abrasive at the sand valve, and is ejected from the high-speed nozzle (item 14) to treat the workpiece.
2, start the air charge: pressure tank sealing and inflation, connect the compressed air pipe to the bamboo joints (7 turn on the compressed air. Quickly open the ball valve 3 6 cone valve closure (piece 3 up. Adjust the pressure reducing valve (9 Rotate the handle, turn it clockwise to pressurize, counterclockwise to depressurize, and observe the pressure gauge until it reaches the proper working pressure.
3. Work: The nozzle starts high-speed sandblasting and pulls out the gun-shaped manual valve (Piece 16 button. Press the button to stop. Adjust the sand valve (Part 12 Rotary valve handle, clockwise rotation of the abrasive flow decreases, counterclockwise The abrasive flow is increased and the abrasive is adjusted to the proper level. At this point, the blasting operation can begin.
4. Shutdown: First close the sand valve, after the work is completed. Continue sandblasting to drain the remaining sand in the blasting pipe, stop sandblasting, close the ball valve 3 pieces 6 and then open the ball valve 5 pieces 17 Exhaust, until the pressure in the pressure tank drops to zero, the cone-shaped closing valve automatically falls, emptying the oil and water Separator (water accumulation in item 8).
