Oil circuit control issues in centrifugal compressors
Thread Content
As stated in the title, I am seeking information on the lubrication oil circuits for the radial and thrust bearings of centrifugal compressors, the control of the floating ring seal oil circuit, as well as the role played by the oil sump at a high level in ensuring the safe and stable operation of the compressor! It would be best to have an oil circuit diagram. Thank you!
The high-level oil tank is designed according to accident scenarios, such that in the event of an accident, the compressor continues to operate inertially with an oil pressure of 0.05 MPa in the unit. Installation height: 5-6 m. You can draw the oil circuit diagram by yourself based on the actual site conditions.
Tilting pad support bearings, in which the pads can swing around a pivot point to ensure they are in the optimal position during operation. The function of a thrust bearing is to withstand the axial thrust that is not completely counteracted by the compressor, as well as the axial thrust generated by the coupling
