Is a pressure booster pump required for the dry gas seal of a centrifugal ammonia compressor?
Thread Content
Dear experts, the dry gas seal for ammonia compressors supplied by SHENGU does not come equipped with a pressurization system (pressure pump); it is stated that a high-pressure nitrogen supply source with a pressure of 0.3 MPa higher than the compressor’s stall pressure is sufficient to eliminate the need for such a pressurization system. Please, experts, could you explain this? Thank you
If there is high-pressure nitrogen, a booster pump is not needed; the system pressure of the ammonia compressor is not high anyway – 0.4 MPa of nitrogen is sufficient for a system pressure of 1.6 MPa
Sometimes a medium gas is used; at the start, the pressure is not high, so the booster pump starts automatically~~~~
Expert, what nitrogen pressure is required? Is a booster pump installed on the ammonia compressor currently in use? Thank you

That means there’s no need to install a pressure booster pump, right?
Our nitrogen pressure is 0.6 MPa, while the pressure used in the device is around 0.38 MPa. It depends on the manufacturer to determine whether this pressure is low enough; if it is too low, then sealing won’t be possible :victory::victory:
Either a booster pump or an external air source that meets the requirements – either one will do
What is the minimum pressure required for the air supply? Please explain. Thank you very much. Is there a pressure booster pump in use currently?
Low pressure at startup; a booster is required, with an outlet pressure of 6.9 MPa
It is not recommended to use a pressure booster pump; medium-pressure nitrogen should be used instead
