JDSG-4-1 Sand Blasting Machine for Steel Pipe Inner/Internal Wall Surface Rust Scale Cleaning
Application
JD SG4-1 series pipeline in wall sandblaster is a special device supporting the use cost sandblasting equipment to clean the pipeline in wall. It can be used in manual work, also in automatic work if equipped with other devices. Applicable for the pretreatment before coating for pipeline inner wall within the inner diameter range 300mm-900mm in the oil, chemical, ship, etc. industries.
Feature
1. JD SG4-1 Sandblaster is commonly used as a supporting tool for other bigger sandblasting equipment to clean the inner wall of pipeline, and it could be operated manually or automatically.
2. The working principle of JD SG 4-1 is changing the shooting angle of the abrasive stream by using a cone shape blasting head or rotary blasting head to cleaning the inner wall of pipeline. The structure is simple and easy for maintenance.
3. Driven by pneumatic motor, two nozzles rotating at the same time, sandblasting efficiency doubled.
4. The major parts use the imported material, largely extending the machine lifetime and lowering down use costs for customers.
5. The cleanness level reaches Sa2.5-Sa3.
Operating principle
When cleaning the inner wall of the pipe, it is necessary to configure a pressure feeding sandblasting machine and an air
compressor with enough air volume. The sandblasting hose of the sandblasting machine is connected with the inner wall cleaner of the pipe, and the manager is pushed into the top of the pipe to clean the work.
The equipment is the use of sand blasting machine pressure sent out of the air abrasive mixed flow, spray to the pipe inner wall cleaner cone nozzle, so that the abrasive guide to form a cone shape diffusion, so as to impact the pipe inner wall, to achieve the purpose of pipe inner wall cleaning.
Remark
1.JD SG4-1 series is a special supporting device for JD pressure sandblasting machine.
2. Adjust the degree of tightness of outer joint can in a way adjust the spinning speed of spinning nozzle holder. And the speed should be controlled within 30~500r/min.
3.If spinning nozzle holder stops spinning or spinning too slowly, it may be because of under pressure, too tight outer joint, stuck bearings or jamed nozzle. Stop the machine, and then adjust and check.
4.Before working,pipeline in wall sandblaster should be put in the in wall from one side to another, and dry pressed air must be inlet. When working, blasting pipe should be pulled out slowly to make it get out at a constant speed. If the cleaning quality can’t meet the requirements, work again to get the satisfactory effect.
5.If the abrasives are blocked and can not be sprayed out, it should be closed down first and exhaust, then have a check. 6). Quick-wear parts should be checked regularly,they should be replaced timely if worn, or they would have a bad influence on the efficiency and the blasting quality,and maybe Exhaust bring accidents
