Let’s see what’s going on here

Could you tell me what these parts are?
Is this carbonized due to lubrication, or is it something else?
How did the sliding bearings and gas seals wear out to this extent? Wasn’t anything done to address the high vibration levels and temperatures?
Samsung centrifuge – burned up like this due to insufficient oil supply? Five accessories: tilting shaft bearings, impeller, air seal, primary shaft, volute, gearbox, impeller, secondary and tertiary shafts
Is the anti-surge system not working well?
Has the lubrication been interrupted? It’s smoking at high temperature. The shaft must be damaged!
#A quick reply with # here means gas compressor. Centrifugal compressor with gear speed control. The pressure is generally not high, but the flow rate is large.
Gear machine. High speed requires high maintenance standards. Be careful! !
This device is called an H-type centrifugal compressor; A is the sliding bearing, B is the open impeller, C are the sliding bearing shells, and D refers to three-stage compression. It could be a problem with the engine’s fuel supply system.
①Kiqingwa bearing-grade oil seal. ②Open impeller tie rod structure ③ High-speed bearing stage air seal ④ First-stage stator ⑤ Low-speed rotor 6 High-speed rotor 7 Impeller 8 Should be the third-stage stator. This should be Cooper’s stage 3 centrifugal gear speed-increasing compressor, which is mostly used in air separation projects. The unit likely experienced bearing wear due to a fuel cut-off, and the impeller scraping the guide ring must have caused that as well!
