Inventory Of Anti-corrosion Measures For Submersible Sewage Pumps

In the chemical production environment, submersible sewage pumps in the sewage discharge link need to be exposed to various corrosive chemicals in the sewage for a long time.

In the chemical production environment, submersible sewage pumps in the sewage discharge link need to be exposed to various corrosive chemicals in the sewage for a long time. Combined with the influence of a series of factors such as the actual working environment. It is easy to have blind spots in operation and maintenance, or to accumulate corrosive chemicals, thereby increasing the possibility of corrosion and reducing the service life of machinery. So where can we start to improve the anti-corrosion ability of submersible sewage pumps?

1. Strengthen the optimization of equipment structure

In order to enhance the corrosion resistance of the equipment, the structural design of the mechanical equipment should be optimized during the design process. When designing, try to choose a relatively simple structure to meet the needs of users, and choose a more anti-corrosion structure at the dead corner. The material is strong, and various methods are used to reduce the gap during the installation stage, thereby improving the corrosion resistance of the mechanical equipment.

2. Strengthen the corrosion resistance of the equipment

When designing its anti-corrosion strength, specific factors such as the medium, service life, use environment, and frequency of use of the equipment should be fully considered, and the design should be strengthened in terms of material thickness and material. Selection of pretreatment techniques and protective coatings. Improve the anti-corrosion strength of sewage pumps and sewage pump stations, and prolong the operating life of the equipment.

3. Choose the right material

Choosing the right sewage pump manufacturing material is the first choice to improve the anti-corrosion performance of the equipment. Different types of metals have different corrosion protection properties and functional advantages. According to different operating media, production environments, and functional requirements, suitable metal materials should be selected for different equipment or different parts of the same equipment. For example, in the production of acetic acid, due to the presence of iodine corrosion, different metal materials such as zirconium, Haas material, and stainless steel are used in different reaction areas. In addition, equipment made of steel as the main material has better acid corrosion resistance than iron, and the corrosion resistance of synthetic metals is better than that of single metals. But when choosing materials, not only its corrosion resistance must be considered, but also many aspects such as manufacturing cost and performance should be considered comprehensively.

4. Rational use of coated corrosion inhibitors

A corrosion inhibitor is a substance that can reduce the corrosion of metals in environmental media. Its working principle is to use its own molecular adsorption characteristics to prevent corrosive gas molecules in the air from contacting the metal surface, and finally achieve the purpose of anti-corrosion.

5. Strengthen equipment management

In the long-term operation of WQ submersible sewage pump, its anti-corrosion performance will gradually decline. Therefore, strengthening equipment management is an important measure to ensure the long-term stable operation of equipment. It should be recognized that the daily maintenance and dynamic monitoring of chemical equipment are essential to ensure its stable operation, establish a responsible system, equip professional and technical personnel, and regularly and regularly conduct corrosion testing and data analysis on chemical equipment. Establish equipment operation database and failure database.
