The main purpose of silicone accessories in membrane sewage treatment plants is to improve system operating efficiency, ensure treatment effectiveness, and extend equipment life. Their functions are closely related to the characteristics of membrane separation technology. Silicone material plays a key role in membrane component protection, system sealing, and auxiliary processing due to its advantages of chemical corrosion resistance, strong flexibility, and good sealing performance.


Overview of O-ring gasket products for membrane sewage treatment plants

The O-ring gasket of membrane sewage treatment equipment is a key sealing component, mainly used for sealing membrane components, pipeline interfaces, and other parts to prevent sewage leakage and external impurities from entering, ensuring the stable operation of the treatment system. Its product types are diverse, covering various materials, specifications, and structural designs, which can meet the sealing needs under different working conditions.

Core characteristics of O-ring gasket for membrane sewage treatment plant

Material diversity: Different rubber materials are selected according to the usage environment, such as ozone resistant ethylene propylene diene monomer (EPDM), high temperature and chemical corrosion resistant fluororubber (FKM), flexible silicone rubber (SIL), oil resistant nitrile rubber (NBR), etc. Among them, fluororubber can be used for a long time at 250 ℃, and EPDM is suitable for water treatment scenarios with high ozone concentration.

Standardization of specifications: The wire diameter range covers 1.00mm to 8.60mm, and some models are labeled according to the inner or outer diameter, such as wire diameter 1.80mm (inner diameter labeling), 2.00mm (outer diameter labeling), etc; The cross-sectional shape is mainly O-shaped, and there are also irregular structures such as star shaped rings, wrapping rings, and overflow rings, which are suitable for different sealing groove designs.

Performance advantages: It has static/dynamic sealing compatibility and can adapt to various motion modes such as rotation and reciprocating; The material has a wide range of medium resistance and can withstand mixed media such as water, oil, and chemical agents; Compact design, easy assembly and disassembly, and relatively low cost.

Application and selection of O-ring gasket for membrane sewage treatment plant

Industry adaptation scenarios

Water treatment industry: used for sealing ceramic membrane cylinders, filtration equipment accessories, aeration tube membranes and other components, with a focus on ozone resistance and acid and alkali resistance. EPDM or fluororubber materials are preferred.

Industrial machinery: When adapting to chemical fiber equipment and pump valve interfaces, O-rings or combination pads can be used to enhance wear resistance and pressure resistance.
