The lubrication of the supporting bearings of the turbine involves pressure, as well as the lubrication oil pressure in the thrust bearings
Thread Content
Must the lubrication oil pressure of the turbine thrust bearing be higher than that of the supporting bearings?
No, the pressure range for thrust bearings is 0.03 MPa to 1.3 MPa, while the pressure range for radial bearings is 0.09 MPa to 0.13 MPa; as long as it’s within these ranges, it’s fine!
The lubrication flow rate for the thrust bearings is higher than that for the support bearings
Not necessarily; it depends on the process design parameters
