Materials play a critical role in the performance of high pressure shaft seals. It is important to select materials that are compatible with the fluids being sealed and can withstand the high pressures and temperatures that may be present. Common materials used for high pressure seals include rubber, plastics, and metals, each with their own advantages and limitations. For example, rubber seals are flexible and provide good sealing performance, but may wear out quickly under high pressure conditions. On the other hand, metal seals are more durable but may not provide as tight a seal

The percentage of an oil seal refers to its ability to effectively prevent leakage. A higher percentage indicates a better sealing capacity, with 100% being the ideal value. However, in reality, achieving a perfect seal is often challenging. Therefore, oil seals with percentages ranging from 25% to 35% are commonly used in applications where a high level of sealing performance is required.

Traditional methods for treating inorganic wastewater include physical, chemical, and biological processes. Physical methods, such as sedimentation and filtration, can remove suspended solids but may not effectively eliminate dissolved inorganic contaminants. Chemical methods, like precipitation and ion exchange, can efficiently remove heavy metals but often involve the use of hazardous chemicals and generate secondary waste that requires further treatment. Biological methods, although more environmentally friendly, are generally less effective for removing inorganic pollutants.
