Such as pulping, cleaning and desanding, liquid level adjustment of each pulp tank or storage tank, thickening and diluting before entering the net and the like, require a large amount of clear water or white water. In production equipment, many equipment need sealing water, such as centrifugal pumps, refiners, pressure screens and the like, and the sealing water plays a role in cooling bearings besides sealing gaps between shafts and sealing elements. However, the sealing water used in the paper manufacturing equipment has more strict requirements, and not only needs higher pressure to meet the requirements of sealing, cooling and the like, but also has certain cleanliness to prevent the pipeline from being blocked and damage to the sealing element or equipment. Therefore, if the sealing water can be used for laying pipelines and realizing an independent supply system, the sealing water is different from water used in different working sections of different daily areas, and the sealing water plays a vital role in ensuring stable production operation and equipment safety. In addition, the recycling of the sealing water can make a certain contribution to saving the using amount of the clean water.
