Product Description

High-manganese steel plates are adopted by extensible arms in the steel pipe inner wall shot blasting machine. The hydraulic motor drives the blast wheels to operate and the steel pipe inner wall shot blasting machine is provided with a hydraulic power unit, a motor and a PLC full-automatic variable frequency control unit which are imported from Germany. Automatic shot blasting technique is adopted by the steel pipe inner wall shot blasting machine/shot peening machine to remove surface corrosion. The high-speed projectile flow beams that are blasted by the high-efficient blast wheels are used to smash scales, rusty layers and dirts on the inner surfaces of the steel pipes so as to obtain a fine glossy surface and enhance the strengths of extension and compression of workpieces, meanwhile to increase adhesion for painting of the inner surface and thereby achieving purposes of preventing corrosion, protecting pipes and prolonging the service life of steel pipes. The degrees of finish and roughness of the workpiece surfaces that are cleaned can reach relative standards.
Working principal of the steel pipe inner wall shot blasting machine: the machine is a roller conveyor shot blasting machine. The steel pipe is placed on the feeding conveying roller and the installation position and conveying speed of the riding wheels are set according to different pipe diameter. The installation angle of the riding wheels can be adjusted to make the steep pipe rotate and go forward. 

The steel pipe entering the blasting area of the blasting chamber is subjected to being attacked and rubbed by the intensive abrasives that are thrown out by the two powerful and efficient blast wheels mounted on the bottom of steel pipe inner wall shot blasting machine, in order to make the scale, rusty layer and other things on the surface be quickly fallen off and make the surface obtain a gloss finish with a certain roughness and show the metal color.During shot blasting, the fallen-off abrasive and dust go through the chamber body hopper and the lower chute and accumulated on the lower of the elevator, then elevated to the separator on the upper of the machine. The separated clean abrasives fall into the hopper of the separator for abrasive cycle use. The dust produced during shot blasting is conveyed to the dust collecting system through the exhaust pipe. After the dust is processed by the dust collecting system, the granular dust is captured and collected and the purified air is discharged to the atmosphere. After the steel pipe is processed, the steel pipe is conveyed out of the blasting chamber and go into the unloading end of the conveyor roller.
