      At present, the main chemical pumps used by petroleum, chemical, pharmaceutical, printing and dyeing enterprises in China can be divided into metal pumps and non-metal pumps. But it needs anti-corrosion, corrosion resistance is generally stainless steel, Stainless Steel Self-Priming pump, stainless steel magnetic pump and so on. Most of the non-metals are cast iron shell steel lined with polymer polyethylene, such as desulfurization pump, mortar pump, but also lined with fluoroplastics, such as fluoroplastics pump, fluoroplastics magnetic pump, fluoroplastics self-priming pump and so on. Today we will talk about the anti-corrosion measures of stainless steel magnetic pumps in stainless steel pumps. Only with effective measures can the pumps have a long life and safe use in chemical production.

      According to physical analysis, it can be known that the common chemical pumps are basically two-stage motor pumps with a speed of 2900 r/min. Cavitation and turbulent corrosion easily caused by excessive speed are the main causes of corrosion. F, Cl separation from intergranular and local corrosion and increase of solid content are another important reasons for the aggravation of corrosion. Through inquiry and test of relevant data, stainless steel material was selected and a new type of stainless steel magnetic pump was used. The performance parameters of the pump were consistent with those of the previous pump, while the speed of the pump was reduced by one time to 1450 r/min. The corrosion rate was significantly reduced. At the same time, the power seal was used to effectively prevent leakage. Leakage.

      Improving pump material

      Through the analysis of the medium composition, a high-grade stainless steel was chosen, in which the composition of Cr, Mo and Ni was proportioned and controlled accordingly. In addition, CLl element was added to improve the F corrosion resistance of the alloy. At the same time, the heat treatment technology level of parts and the precision of spare parts processing were improved. Stainless steel 304:Universal type No. 18/8 stainless steel. Products such as corrosion resistant containers, tableware, furniture, railings, medical equipment. The standard ingredient is 18% chromium plus 8% nickel. The stainless steel is non-magnetic and can not be changed by heat treatment to change its metallographic structure. The GB brand is 0Cr18Ni9.

      304L: It has the same characteristics as 304, but low carbon makes it more resistant to corrosion and easy to heat treatment. However, it has poor mechanical properties and is suitable for welding and products that are not easy to heat treatment.

      Practice has proved that the measures taken by our factory are very effective to ensure the safety and stability of various corrosive media, can obviously solve the problem of corrosion, and has achieved better economic and environmental benefits. Therefore, we believe that with the development of manufacturing technology in the manufacturing industry, the pump problem in the chemical industry will be gradually improved and solved.
