Operating parameters:

Temperature: -40 ℃~260 ℃

Pressure: negative pressure~0.2MPa

Speed: ≤ 150m/s

Application scope: Can be used for working conditions where the compressor inlet is close to atmospheric pressure, such as ammonia compressors in fertilizer plants, ethylene and propylene compressors in ethylene plants, etc

Structural features: suitable for working conditions where the pressure of the sealed gas is close to that of the atmosphere; Adding a first stage labyrinth seal before the series dry gas seal can increase the pressure of the first stage seal gas, ensure that the first stage seal of the series seal is in a positive pressure difference state, and also reduce the flow rate of returned seal gas to the compressor, improving compressor efficiency. The second stage seal in the series seal can still play an auxiliary safety role; The dynamic ring adopts a floating design with strong adaptability to working conditions

Application condition: suitable for working conditions where the pressure of the sealed gas is close to the atmosphere
