Dredge clean    

in recent years, chemical cleaning of the area has gradually expanded. Use chemical cleaning of boiler and heat exchange equipment scale has been adopted by more people, in many parts of the chemical cleaning is also from this perspective, and has made great economic, energy-saving contribution to the cause.  

  This type of work, large, wide, will continue to be one of its main areas of cleaning. Meanwhile chemical cleaning or there is a large potential market and area, namely hotels, restaurants, residential sewer cleaning, this type of cleaning is also a pressing social need. Currently due to various reasons there is not a lot of roll out, but from the work unit, the effect is very significant, is deeply welcome the user. At district level, especially in large,, chemical cleaning of small city workers to enter in this field, for life out of the city.  , Such as hotels, restaurants, residential buildings, life with water pipes after the delivery, for more than 10 years, jams can occur in a few years (not including careless use of sewer to the foreign body blockage), bring great inconvenience to people's lives, especially in very particular about tall, this is a very painful thing. In recent years in many cities, this kind of problem reflected very strongly, with the improvement of people's living standards as well as modern housing, this problem will become more prominent.  

  This problem occurs because, due to water containing calcium, magnesium and other fouling substance, second is used in the process, the water in the mixing of sediment, urine or oil and other things, make it easier for sewage than water scaling. Shortly after the new building, sectional area of the pipe began to decrease, lacking flow down, and finally blocked. At this point it is necessary to take measures to clean up.  

of course, located in the Interior bent, fine and complicated pipe cleaning is a very troublesome thing. Have been using artificial mechanical dredge or practice of replacing all pipes, doing so is not only time-consuming, labour-intensive, and the problem cannot be solved, still be blocked soon, attention. Chemical cleaning can cause this problem is successfully solved.  

  at present, some hotels, restaurants, residential cleaning, cleaner works well, welcomed by using units. But for now, more to worry about this kind of problem, for chemical cleaning workers to publicize, to solve the problem.   Water sewer cleaning and cleaning of boilers and other equipment have the same points, but also has its own characteristics.  

  plumbing and construction processes;

1. check the cleaning object   hotels, restaurants, residential sewer lines and equipment, bathroom, Jacuzzi, sprinkler, basins, pools and its connected pipeline; pool, urinal toilet stool and its connected pipeline; kitchen sinks, floor drains and connecting pipes and their connection to outdoor sewage pipe and so on. Before cleaning, first figure out pipe context and understanding of life, use of congestion, buried and exposed portion of a building is damaged, and so on. The damaged equipment and pipelines must be replaced, cleaning can be carried out. In parallel with the query pipeline, pay attention to understand the material, except for cast iron and ceramics, but also what kind of material in the system, equipment for structural materials such as cement and piping, best to separate it from the system when cleaning to avoid corrosion.  

2. subparagraph   will need to be cleaned into a clean section of the pipeline, this work before the cleaning must be done well. Various buildings, its number of floors, number of cells are not the same, sewers and volume are not the same device. To facilitate the plumbing, cleaning is generally divided into several small, segmented approach based largely on sewer capacity, floor height, easy cleaning, and the possibility of segmentation. Generally three or four stories within a unit for a better.  

3. closure work   This is an important part of cleaning. First of all will be blocked at the first fragment from the top down, this segment general observation holes in pipeline (hole) and then communicated with the air vents and other pipeline parallel vents blocked, leaving only two vents at the top of the paragraph, to a port into cleaning liquid, an opening used to exclude air. Closing at 1-2 should be able to withstand the pressure kg/cm 2, avoid cleaning, closing because of liquid column hydrostatic break attack. If at the closure valves, better not to depend entirely on the valve closing, because the valves are used for a long time, not locked, and other closing the corresponding measures should be taken.  

4. leakage test   after the completion of the closure, to leak test. Leak test method is this: from the left of the paragraph at the top of the liquid inlet to the water, fill the system and observe the water level is falling, falling, find the leak, leak, if you can keep the water level, you can proceed.  

5. cleaning   cleaning into a number of segments one by one from the top down, method of adding acid to leak water in the same way, generally using immersion cleaning. If the speed is too slow or stopped, the scale didn't wash, part may be appropriate to replace the cleaning solution, continue cleaning until clean.   Wash in the first paragraph, under the second paragraph of the closure blocked, open the closure of the first paragraph, so cleaning cleaning solution into the second paragraph, concentration If cleaning is not enough parts to replace or replace all can be taken until clean. Third and fourth paragraphs ... ... One by one. Cleaning method of the same, completion of a range of cleaning should be put in a lot of water, open all closure, to bring the system back to normal.   Chemical cleaning, domestic water sewerage than some cleaning of boilers and other equipment are complex, but as long as the cleaners take appropriate measures according to actual situation, develop a detailed cleaning program, cleaning is safe and reliable, looking the chemical cleaning staff to enter in this field.
