● Sandblasting gun for pipe inner wall
道内壁喷砂枪 主要用于小型管道内壁的喷砂处理，因为管道狭小，正常的向前喷射的单进风和 The sandblasting gun for the inner wall of the pipe is mainly used for sandblasting the inner wall of small pipes. Because the pipe is narrow, the normal single-inlet air and
The dual inlet air blasting gun cannot change the direction in the pipe, and it is impossible to blast the inner wall of the pipe. This requires the abrasive to be sprayed forward.
内壁喷砂枪 就是在这种情况下应运而生的。 In order to achieve the purpose of sandblasting the inner wall of the pipeline, the angle of the wall must be changed . In this case , the inner wall sandblasting gun came into being.
从喷砂模式上分： The sandblasting gun on the inner wall of the pipe is divided from the sandblasting mode:
300MM 以下的用散沙头的模式， 300MM 以 There are loose sand head type inner wall guns and rotating inner wall guns. Generally, sand pipe heads with a diameter of less than 300MM are used.
Use the rotary head mode.
从材料上来说：有硬质合金钨钢的，也有碳化硼的。 In terms of materials, the sandblasting gun on the inner wall of the pipeline is made of tungsten carbide or boron carbide.
管道内壁喷砂枪 ，根据客户使用磨料的不同，灵活应用有针对性的材料 The sandblasting gun for the inner wall of the pipeline produced by Dongguan Humen Meijun sandblasting equipment can flexibly apply targeted materials according to the different abrasives used by customers.
And layout, the main purpose is to improve the service life of spare parts under different conditions.
3 major improvements of the 2013 MJ50-300MM inner wall sandblaster:
1) The height of the loose sand head increases, which increases the wear time and increases the life;
2) Increase the diameter of the loose sand head to 32MM, so that the blasting area is increased, and the cleaning of the inner wall of the pipeline is more uniform and concentrated;
3) The inclined surface of the loose sand head is changed from a flat surface to a concave arc, which conforms to the direction of the airflow, reduces the impact angle of the sand particles on the loose sand head, reduces the wear intensity, and makes the sand particles smoother.
Increasing the life of the loose sand head also increases the uniformity of the impact of sand particles on the inner wall of the pipeline.
Internal component installation method:
Step 1: Install the screw and the sand separator first, thread the screw into the sand separator, and tighten the two ends with nuts.
Step 2: Install a screw sheath (small oblong tube), then install a nut, then install a screw sheath, and then a nut;
Step 3: Install the large nozzle in the direction, and the end with the bell mouth is facing the sand separator;
Step 4: Attach the red spray gun screw cap.
The fifth step: the previous nut --- the previous loose sand head --- add a washer --- on the spring-add the washer (optional) --- on the nut.
Step 6: Put the gun body from the front, screw the red spray gun screw cap (polyurethane cap needs to be added with water tape or glued firmly, and the steel sleeve can be tightened), and the assembly is completed.
Step 7: According to the size of the sand blasting pipeline and the strength of the sand blasting, adjust the distance of the scattered sand head from the spray gun mouth.
The reflection angle of the sand particles is large, and the spray pipe is also slightly larger. The reflection angle of the sand particles is smaller at a longer distance, and the spray pipe is also smaller, and the intensity is smaller.
