This paper set the dry gas seal and the characterization parameters of its stable operation as the research object. A changed hypothesis model was established for the characterization parameters of stable operated dry gas seal. At the same time, the change rules and the relationships between relating characterization parameters of stable operated dry gas seal was studied based on gas lubrication theory and correlation analysis software, which can verify and improve the characterization parameter model for stable operation. The nondestructive testing methods for the correlation characterization parameters was studied, which can achieve the new method suitable for field application criterion of the stable operated dry gas seal, reduce the energy, raw material waste and environmental pollution caused by early failure or improper follow change of the dry gas seal and achieve the goal of energy conservation and emissions reduction.Therefore, the theory analysis in this paper is to improve the stable operation of dry gas seal, save energy, reduce emissions and enhance safety application, which can provide more theoretical support on the efficient service and safe operation of dry gas seal equipment.
