Application of corrosion protection materials for desulfurization pump casing

Thread Content

As an important medium transportation equipment for enterprises, desulfurization pumps not only affect the safe and continuous operation of enterprises, but also have a particularly large impact on energy consumption. Common problems in the desulfurization process of desulfurization pumps include erosion, cavitation, abrasion, etc. Erosion and corrosion are caused by the fact that the PH value of the medium in the desulfurization pump is generally between 4 and 5. Long-term immersion in strong acidic liquids causes erosion and corrosion of the equipment. Cavitation is due to the fact that there is often a certain amount of air in the circulating pump. The collapse of small bubbles during the rapid flow process will cause cavitation to the equipment. The impact of cavitation on the desulfurization pump is far more complex and difficult to predict than solid corrosion. Abrasion: Because the priming slurry often contains a large number of solid particles, such as desulfurization media, these media will wear the pump casing to a certain extent during the flow process, leading to equipment abrasion under acidic conditions. For a long time, companies have usually replaced spare parts to meet the production process requirements, or used steel-lined wear-resistant plastic materials or improved metal materials to extend their service life. In this way, both the production company and the user unit have increased the cost investment. Is there a better way to protect the desulfurization pump casing? Sole carbon nanopolymer material can solve this problem. This material can be used to resist corrosion, wear, and cavitation in fluid environments, and can adapt to alternating changes in temperature. The material has good resistance to chemical corrosion and can protect the shell of the desulfurization pump from erosion and corrosion damage. ； Super wear resistance can resist the abrasion caused by solid particles in the desulfurization slurry ； The material has good leveling properties and fully meets the operating requirements of desulfurization pump equipment. The desulfurization pump casing of a certain company was seriously corroded. By using this material technology, the wear repair and protection of the desulfurization pump was effectively realized on site, and it met the company's usage requirements, which provided a good solution for the company. * * It reduces maintenance costs and downtime, and is highly recognized by enterprises. The specific repair steps are as follows: 1. Prepare the required materials and tools and take safety precautions ； 2. Disassemble and scrub the desulfurization pump to be protected ； 3. Sandblast the desulfurization pump to remove dirt and oxide layers on the surface to achieve a clean and rough finish. ； 4. Mix the Sole carbon nanopolymer material according to the proportion until the color is uniform and there is no color difference. ； 5. Apply the mixed material to the surface of the desulfurization pump casing to be repaired to ensure that it is fully bonded to the pump casing. ； 6. After curing, apply a layer of material to prevent cavitation and improve pump efficiency.
