Does the overall gear-type compressor have a coupling?
Thread Content
I saw that API617 consists of four chapters, one of which is dedicated to gear compressors in their entirety. Could those who are experts tell me how a gear compressor as a whole is defined? And do gear compressors come with couplings?
A coupling is required to connect the input shaft of the toothed compressor to the drive machine.
A integral gear compressor is one in which the compressor and the speed increase gearbox are combined into one unit; there is no coupling inside it, but there is a coupling between it and the drive mechanism, usually a diaphragm coupling.
Agree with the opinion above. Integrating speed increase with centrifugal compression is an innovation; it’s unknown how many stages this can achieve.
We have a Siemens turbine compressor that is of the fully geared type; the turbine (the driving unit) is connected directly to the gearbox, without the use of a coupling. I was wondering why it’s connected directly and not via a coupling
An overall gear-type compressor is essentially one in which impellers are installed at both ends of the gears, allowing for multiple stages to be created. A coupling is required; the compressor has an input shaft, a gear shaft, and a high-speed shaft for mounting the impeller, etc
