The main structure of the steel pipe inner wall sandblasting machine includes a compressed air system, a sand grain supply system and a control system. ‌

The compressed air system provides high-pressure compressed air, which is delivered to the sandblasting gun through a pipeline to provide power for the sandblasting process.

The sand grain supply system is responsible for delivering abrasive particles to the nozzle. Common supply methods include pressure type and gravity type. The pressure supply system pushes abrasive particles from the hopper to the nozzle through compressed air, while the gravity supply allows abrasive particles to flow naturally to the nozzle.

The control system is used to control the working parameters of the sandblasting machine, such as the spraying pressure, spraying time, spraying distance, etc., and adjusts them according to the different requirements of the workpiece to achieve precise sandblasting effects.

The design and configuration of these systems ensure that the sandblasting machine can efficiently and accurately process the inner wall of the steel pipe, remove impurities such as dirt and scale, and ensure the safety and environmental protection of the operation. ‌
