Cleaning method of central air-conditioning pipe

1, first of all, use a robot with a camera to enter the central air-conditioning pipe, and see the pollution in the pipeline, so that the next step will be more.

2, conscientiously look at the design and installation drawings of central air conditioning pipes, work out a detailed pipeline cleaning plan, and obtain the consent of customers, then choose the right cleaning equipment.

3, open two holes in the proper location of the central air conditioning duct, then use the airbag to block the ends of the pipes in the two openings.

4. Use a suitable hose to connect the vacuum cleaner to one of the construction holes, so that the negative pressure air flow will be generated in the air duct, and all the pollutants and dust in the pipe will be sucked into the vacuum cleaner.

5, after the suction, then choose a suitable cleaning soft shaft brush to clean the pipeline, or use the pipe cleaning robot to complete.

6. After cleaning work, use robot to take pictures of the cleaning condition to confirm the quality of the cleaning.

7, if the quality of the cleaning is over, then the pipeline should be sterilized, and the ultraviolet ray should be used for disinfection, so that the two pollution can be avoided.

8, after all the central air-conditioning cleaning work is completed, we must carefully clean up the site, so as to ensure that the next step can be carried out smoothly.

9, next is the scene resumption, because the seal is removed during the cleaning process, at this time, they should be re installed, and the size of the outlet will also be adjusted to ensure moderate air volume.

10, after all these are completed, even if the central air-conditioning pipe cleaning operation is successfully completed, at this time, we must sort out the details of the construction and submit it to the customer, and everything is done.

1, the pipe butt welding joint should be neat in the inner wall, and the inner side of the steel pipe should not exceed 10% of the wall thickness, and not more than 2mm.

2. When the components of the pipelines are not connected, when the error of the inner cavity exceeds 10% of the wall thickness and does not exceed 2mm or the surface misalignment exceeds 2mm, the repair should be carried out according to the relevant requirements.

When 3 or two pipe ends are assembled, there must be a gap between the blunt edges. Small gap, easy to cause the root of the gap is not welded too large, the root is easy to weld. The gap of the same welding joint should be uniform in all directions, but when the horizontal pipe is fixed beside the large diameter pipe, the contraction of the weld seam should be taken into account and the clearance of the welded joint can be enlarged appropriately.

4. Pipes with equal wall thickness and equal wall thickness can be used for fixing the wrong variables and the corresponding gap. For large diameter pipe formation, the way of spot welding of angle steel at the end of pipe can be adopted.

5, make up the angle of the interface of the group and the gap of the mouth, and check the qualification with the welding ruler and the angle gauge, then fix the interface.

Central air-conditioning pipe cleaning Many details of time can not be ignored. Of course, how to learn how to clean correctly is also needed to understand. The above is to introduce the cleaning methods and cleaning matters of central air conditioning pipes. Here is the end. If you want to know more information about air conditioning, please continue to pay attention to Shanghai's reputation.
