管道疏通流程是什么?

  生活用水下水道的化学清洗较之锅炉等设备清洗要复杂些,但只要清洗者根据实际情况采取相应的措施,制定一份详细清洗方案,清洗起来有目标性,效率也会提高不少,所以我们应该先做好计划!
  The chemical cleaning of domestic sewage is more complicated than that of boiler and other equipment, but as long as the cleaner takes corresponding measures according to the actual situation and formulates a detailed cleaning plan, the cleaning is targeted and the efficiency will be improved a lot, so we should make a plan first!
  管道疏通流程如下:
  The pipeline dredging process is as follows:
  1.在清洗之前,首先应搞清楚管道的来龙去脉,并了解使用年限,使用情况,堵塞情况,埋入和有没有其它公司来清洗过等问题。不要首先就对已损坏的设备和管线更换,这样会造成损坏度加大,如有水泥等结构材料的设备和管道,清洗时尽量与系统隔开,避免腐蚀。
  1. Before cleaning, the origin and development of the pipeline should be made clear, and the service life, usage, blockage, embedment and whether other companies have cleaned the pipeline. Do not replace the damaged equipment and pipelines first, which will increase the degree of damage. If the equipment and pipelines with structural materials such as cement are cleaned, they should be separated from the system as far as possible to avoid corrosion.
  2.分段将需要清洗的管线分成若千个清洗段,这一工作在清洗前要做好。
  2. Divide the pipeline to be cleaned into thousands of cleaning sections by sections, and this work should be done well before cleaning. 
  各种建筑物,其楼层数、单元数不相同,下水道和设备容积也不尽一样。为便于管道疏通,一般要分成几个小的清洗段,分段的办法主要根据下水道的容积、楼层的高低、清洗方便,以及分段的可能性。一般以一个单元内的两层楼为一段较好。
  The number of floors and units of buildings is different, and the volume of sewers and equipment is also different. In order to facilitate the pipeline dredging, it is generally divided into several small cleaning sections. The segmented method is mainly based on the volume of the sewer, the height of the floor, the convenience of cleaning, and the possibility of segmenting. Generally, it is better to take two floors in a unit as a section.

  3.堵口这是管道清洗中的重要一环。首先将自上而下的一个分段处堵死,此分段处一般在管道干线的观察孔(手孔)处,然后将与大气相通的通口和与其他管线并联的通口堵死,只留下该段上方的两个通口,一个口用来进清洗液,一个口用来排除气体。堵口处应能承受1-2公斤厘米2的压力,避免清洗时,由于液柱静压而使堵口破袭。堵口处若有阀门,不完全依靠阀门堵口,因为阀门使用年久,不易关严,应采取与其他堵口相应的措施。
  3. Plugging is an important part of pipeline cleaning. First, block up a section from the top to the bottom, which is generally at the observation hole (hand hole) of the main pipeline, and then block the vent connecting with the atmosphere and the vent in parallel with other pipelines, leaving only two ports above the section, one for cleaning fluid and the other for gas removal. The plug should be able to bear a pressure of 1-2 Kgcm 2 to avoid breaking the plug due to the static pressure of the liquid column during cleaning. If there is a valve at the plug, it is not completely dependent on the valve plug, because the valve has been used for a long time and is not easy to close tightly, corresponding measures should be taken with other plug.
  4.试漏堵口工作完毕后,要进行试漏。试漏的方法是这样:从留下的该段上方的进液口处向里加水,直至加满该系统,并观察水位是否下降,若下降,查找漏处,处理漏口,若能保持水位,即可进行下一-步操作。
  4. After the completion of leak test and plugging, leakage test shall be conducted. The method of leakage test is as follows: add water from the liquid inlet above the left section until the system is filled, and observe whether the water level drops. If it drops, find the leakage and deal with the leakage. If the water level can be maintained, the next operation can be carried out.
  5.清洗按分成的若干段自上而下逐段进行清洗,加酸的方法同试漏加水的方法一样,一般采用浸泡式清洗。若清洗速度过慢或停止后垢还没洗净,可适当更换一部分清洗液,继续清洗,直至洗净。一段洗净后,将二段的下堵口堵死,打开第 一段的堵口,使清洗液流入二段清洗,若清洗液浓度不够,可采取部分更换或全部更换,直至洗净。第三段、第四段……依次进行。几个单元清洗方法步骤相同,一个单元清洗完毕应放入大量的水冲洗,打开所有的堵口,使系统恢复正常。
  5. The cleaning shall be carried out from top to bottom according to several sections. The method of adding acid is the same as that of leakage test and water adding. Generally, immersion cleaning is adopted. If the cleaning speed is too slow or the scale has not been cleaned after stopping, a part of the cleaning solution can be replaced appropriately, and the cleaning will continue until it is cleaned. After cleaning the first section, block the lower plug of the second section, open the plug of the first section to make the cleaning fluid flow into the second stage cleaning. If the concentration of the cleaning solution is not enough, partial or full replacement can be adopted until the cleaning. Third, Fourth In turn. The cleaning methods of several units are the same. A large amount of water should be put into a unit after cleaning, and all the plugs should be opened to make the system return to normal.
