I have been looking at information on the ammonia synthesis process recently, and I would like to ask some questions regarding the turning devices for centrifugal compressors.
Thread Content
What does a typical turbine-driven centrifugal compressor turning gear look like, where is it installed, and how is it started? Does anyone who knows the answer know it? It would be great if there were pictures:$
Could the elder brother explain it in more detail or send two pictures?
The post is about to sink, so I’m boosting it myself~. Does anyone here have photos of the barring device for turbine centrifugal compressors? Please share them so I can learn from them
Have you never seen a turning motor? Generally, on both sides of the turbine, there is a very small motor, the turning motor, which can be started with a single button press; the switches are usually located on the on-site control panel, with start and stop buttons. For the cranking of our three compressors, it basically involves rotating the shaft 360 degrees. The general sequence is as follows: turn on the isolation air supply, start the lubricating oil pump, wait until oil begins to flow out of the unit, start the cranking motor, rotate the shaft 360 degrees, stop the cranking motor, turn off the lubricating oil pump, and once no more lubricating oil flows out of the unit, turn off the isolation air supply
