Operating parameters:

Temperature: -40 ℃~260 ℃

Pressure: ≤ 1MPa

Speed: ≤ 150m/s

Application scope: Can be used for catalytic and coking rich gas compressors, desorption compressors, etc. in petroleum refining production

Application Industry: Petroleum Refining

Structural features: Suitable for working conditions where process gas is not allowed to leak into the atmosphere, but a small amount of sealing gas is allowed to leak into the process gas; Inject a sealing gas with a pressure higher than 0.2-0.3Mpa of the process gas between the two sets of seals, and the leakage direction of the sealing gas always faces the process gas and the atmosphere, ensuring that the process gas will not leak into the atmosphere; The dynamic ring adopts a floating design with strong adaptability to working conditions

Application conditions: Applicable to hazardous gases that are not allowed to leak into the atmosphere, but allow a small amount of sealing gas to leak into the process gas
