300-900mm pneumatic rotating inner wall sandblasting gun
300-900MM sandblaster for inner wall of pneumatic rotating pipeline needs to be matched with pressure sandblaster and air compressor, which is equivalent to the normal use of single-inlet and double-inlet sandblasting guns, but only using two guns 360 degrees Rotary spray to achieve the purpose of cleaning the inner wall of the pipeline.
The inner wall sand blaster nozzle is made of high temperature sintered pure boron carbide material. Its hardness is extremely high, second only to diamond, and it is resistant to abrasion, which prolongs the service life of wearing parts to the limit. This sandblaster is suitable for sandblasting the inner wall of φ300-900mm pipe.
The main air bag of the 300-900 inner wall sand blaster is imported from Taiwan. The high-pressure air is used to blow the air motor blades in the air bag, so that the gear is rotated to drive the nozzle Y-shaped seat to rotate 360, and then the two are mounted on the Y The nozzles at a 90 ° distribution in front of the seat rotate at a uniform speed to achieve a uniform 360-degree blasting. At the same time, the inner wall sand blaster moves back and forth linearly at a uniform speed along the length of the pipe, thereby achieving the purpose of cleaning the inner wall of all lengths of the pipeline. After cleaning The rear surface quality grade can reach Sa2.5-Sa3.
300-900 inner wall sand blaster is suitable for abrasives: brown corundum, copper ore, quartz sand, cast steel shot, cast steel sand, corundum and other abrasives with a particle diameter of less than 2mm.
