Introduction to Dry Gas Seals
Dry gas seals are a type of mechanical seal used in rotating equipment, such as pumps and compressors. They are designed to prevent the leakage of process gas by creating a non - contacting seal interface. Unlike traditional wet seals that rely on a liquid film for lubrication and sealing, dry gas seals use a gas film. This offers several advantages, including reduced power consumption, lower maintenance requirements, and enhanced environmental friendliness as they minimize the risk of fluid leakage into the atmosphere. Dry gas seals are widely used in various industries, such as oil and gas, chemical, and power generation.
