Key properties and material selection of seals in water treatment equipment

With the increasing shortage of water resources and the increasingly serious environmental pollution, water treatment equipment plays a vital role in ensuring water resources safety and environmental protection. As one of the indispensable components of water treatment equipment, seals play a key role in the stable operation and long-term use of equipment. This article will discuss the key properties of seals in water treatment equipment and the importance of material selection.

Key performance of seals in water treatment equipment

Corrosion resistance: Water treatment equipment often needs to treat a variety of water quality, including water containing acids, bases, oxides, salts and other chemicals. Therefore, seals need to have excellent corrosion resistance and can work stably in corrosive environments for a long time.

High pressure resistance: high pressure water flow is often present in water treatment equipment, and the seals need to be able to withstand the impact of high pressure water flow, maintain stable sealing performance, and prevent water leakage.

Wear resistance: Seals in water treatment equipment often need to run for a long time, so they need to have good wear resistance, be able to resist water erosion and friction, and maintain the long-term reliability of seals.

The importance of sealing material selection

Fluororubber (FKM) : Fluororubber has excellent corrosion resistance and high temperature resistance, and is suitable for highly corrosive and high temperature environments in water treatment equipment.

Polytetrafluoroethylene (PTFE) : PTFE has good corrosion resistance and low friction coefficient, which is suitable for sealing valves, pumps and other parts of water treatment equipment.

Neoprene rubber (NBR) : NBR has good oil resistance and wear resistance, and is suitable for some seals in water treatment equipment that need to withstand lubricating oil, fuel oil and other media.

Conclusion

Seals play a crucial role in water treatment equipment, and their performance and material selection directly affect the stable operation and long-term use of the equipment. When selecting sealing materials, it is necessary to fully consider the working environment and requirements of the water treatment equipment, and select sealing materials with excellent corrosion resistance, high pressure resistance and wear resistance to ensure the safe and reliable operation of the equipment, and provide strong support for ensuring the safety of water resources and environmental protection.
