Internal structure diagram of a centrifugal compressor
Thread Content
Dear seniors: Are there high-resolution images of the internal structure of centrifugal compressors? It would be great if there were descriptions of each component, and animations would be even better. Also, what is the function of the primary seal gas, secondary seal gas, and isolation gas in centrifugal compressors? Finally, it comes to the commissioning of the centrifugal compressors – which one should be started first and which one later? It’s an emergency! Thanks first!

1. Before starting up, introduce isolation gas first, followed by sealing gas (the booster pump should also be activated). 2. Establish oil pressure and rotate the turbine shaft. 3. Direct steam to the pipe in front of the shut-off valve to warm it up
The function of dry gas is to maintain a certain gap in the mechanical seal, while the function of isolation gas is to prevent lubricant from leaking into the mechanical seal and damaging it
