Details

Meijun Model: MJ300-900MM Inner Wall Sandblaster:

The gun head is designed to rotate 360 degrees, and the nozzle is made of high temperature sintered pure boron carbide.

Suitable for rust removal, oxidation layer cleaning, anticorrosive engineering, and pre-painting treatment of pipeline inner walls

  管道内壁喷砂枪 Sandblasting gun for inner wall of pipeline

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双进风喷 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, normal single-inlet and double-inlet blasting forward spraying.

The sand gun cannot change the direction in the pipe, so it is not possible to blast the inner wall of the pipe. This requires that the abrasive sprayed forward must change the angle direction.

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 inner wall sandblasting gun emerged at the historic moment.

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 以上用旋转头的模式。 There are loose sand head type inner wall guns and rotary inner wall guns. Generally, the sand head mode is used for pipes with a diameter of less than 300MM, and the rotary head mode is used for more than 300MM .

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.

管道内壁喷砂器 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和布局, The sandblasting gun for the inner wall of the pipeline produced by Dongguan Humen Meijun sandblasting equipment can flexibly apply targeted materials and layouts according to the different abrasives used by customers.

The main purpose is to improve the service life of spare parts under different conditions.

MJ300-900MM Pneumatic Rotary Pipeline Sandblaster
MJ300-900MM sandblasting device for inner wall of pneumatic rotating pipeline needs to be used together with pressure sandblasting machine and air compressor, which is equivalent to the normal use of single inlet and double inlet.
The sand blasting gun is just a 360 degree rotation spray with 2 guns to achieve the purpose of cleaning the inner wall of the pipe.
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 wear and tear.
Life. This sandblaster is suitable for sandblasting the inner wall of φ300-900mm pipe.
The main air bag of the MJ300-900 inner wall sand blaster is imported from Taiwan. The high-pressure air is used to blow the air motor blades in the air bag, thereby driving the gear to drive the nozzle.
The Y-shaped seat rotates 360 degrees, and then drives two nozzles installed at a 90 ° distribution in front of the Y-shaped seat to rotate at a uniform speed to achieve a uniform 360-degree blasting purpose. At the same time, the inner wall blaster
It moves back and forth linearly at a constant speed along the length of the pipe, so as to achieve the purpose of cleaning the inner wall of all lengths of the pipe. The cleaned surface quality grade can reach Sa2.5-Sa3.
The sand blasting device can manually and uniformly pull the sand blasting operation, and can also be used in conjunction with the automatic conveying device to achieve automatic operation.
E.g:
1) Use a uniform speed motor to pull back the sand blasting tube at a uniform speed to achieve a uniform speed back movement;
2) Install the fixed track into the pipeline to realize the sand blaster automatically retreat along the track at a uniform speed.
MJ300-900 inner wall sandblaster 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.

款 MJ50-300MM 2013 MJ50-300MM
Three major improvements of the sandblaster on the inner wall of the pipeline:
1) The increase in height increases the wear time, which also 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 is more compliant with the direction of the air flow, reduces the impact angle of the sand particles on the loose sand head, reduces the wear intensity, makes the sand particles smoother, and increases the life of the loose sand head. Impact of sand particles on the inner wall of the pipe.
 
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.
