Operating parameters:

Temperature: -40 ℃~260 ℃

Pressure: ≤ 8MPa

Speed: ≤ 150m/s

Application scope: It can be used for circulating hydrogen compressors, high-pressure hydrogenation compressors, natural gas compressors with high hydrogen sulfide content in petroleum refining production, as well as cracking gas, ethylene, propylene gas compressors, synthetic gas compressors, etc. in ethylene production

Structural features: Suitable for working conditions where neither process gas leakage into the atmosphere nor blocking gas entry into the machine is allowed; In addition to the process gas itself, an additional path of nitrogen gas needs to be introduced as the gas used in the middle labyrinth of the second stage seal. When the primary seal fails, the secondary seal can play a supplementary safety role; The dynamic ring adopts a floating design with strong adaptability to working conditions

Application condition: Suitable for working conditions where neither process gas is allowed to leak into the atmosphere nor sealing gas is allowed to enter the machine
