Nitrogen seal for reciprocating compressors
Thread Content
As the title suggests, I would like to ask fellow sailors: what pressure is used to control the nitrogen in the compressor’s nitrogen seal in your areas?

It is generally related to the compressor outlet pressure; there is a value of 0.2, and for two-stage compressors it is 0.15 and 0.25 respectively
Here, it’s no higher than 0.1MP. I’d like to discuss with everyone what pressure level is used there.
Our unit regulates the system nitrogen pressure; the pressure is not controlled directly, but each stage of the compressor is equipped with a flow meter to control the flow rate
For this matter, it’s best to ask the manufacturer, as their specifications are the most realistic.
It depends on the design requirements, I guess
0.15 and 0.1 Mpa respectively
Pressure packing 0.1, isolation packing 0.05
It’s best to ask the manufacturer. The value is 0.15 when it’s close to the cylinder, and 0.1 when it’s close to the bearing housing. It was the first no-load test run. Another team was responsible for testing Machine B, while we tested Machine A. They introduced nitrogen without any prior request, and due to the high pressure, one sealing ring was damaged; smoke started coming out immediately
