Inventory of anti-corrosion measures for submersible sewage pumps

In the chemical production environment, the submersible sewage pumps in the sewage discharge link of Solar Water Pump Manufacturers need long-term contact with various corrosive chemicals in sewage.

In the chemical production environment, submersible sewage pumps in the sewage discharge process need long-term contact with various corrosive chemicals in the sewage. Combined with the influence of a series of factors such as the actual working environment. Operation and maintenance are prone to blind spots, or the accumulation of corrosive chemicals, which increases the potential for corrosion and reduces the lifespan of the machinery. So where should we start to improve the anti-corrosion ability of the submersible sewage pump?

1. Strengthen the optimization of equipment structure

In order to enhance the corrosion resistance of equipment, the structural design of 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 in 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 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. Choose pretreatment techniques and protective coatings. Improve the anti-corrosion strength of sewage pumps and sewage pumping stations, and prolong the operating life of 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. Appropriate metal materials should be selected for different equipment or different parts of the same equipment according to different operating media, production environment and functional requirements. For example, in the production of acetic acid, due to the presence of iodine corrosion, different metal materials are used in different reaction zones, such as zirconium, Hass material, stainless steel, etc. In addition, the 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.

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 anticorrosion.

5. Strengthen equipment management

During long-term operation of Sewage Pump Factory WQ submersible sewage pump, its anti-corrosion performance will gradually decline. Therefore, strengthening equipment management is an important measure to ensure long-term stable operation of equipment. It should be recognized that the daily maintenance and dynamic monitoring of chemical equipment is essential to ensure its stable operation. A responsibility system should be established, professional technicians should be assigned, and corrosion testing and data analysis of chemical equipment should be carried out on a regular basis. Establish equipment operation database and failure database.
