Which is higher, the oil pressure of the turbine radial bearing or that of the thrust bearing?
It should be the same, oil coming from one oil pump.
As the engine speed increases, the oil pressure in both the radial bearings and the thrust bearings decreases, but the decrease is relatively greater in the thrust bearings
Random group load; the thrust bearing experiences a relatively greater decrease
The radial pressure is low, while the pressure at the thrust pads is high
The radial pressure is low, while the pressure at the thrust pads is high
The pressure of the thrust is low, while the radial pressure is high.
The pressure is normally around 0.15 MP; it varies depending on the control valve used to regulate the flow into the bearing
In my opinion, it is best to adjust the oil pressure in each oil inlet line according to the manufacturer’s technical specifications; there is usually a minimum requirement. When making adjustments, the pressure can be increased slightly based on the temperature of the bearing shells – generally, the pressure for radial bearing shells should be higher than that for thrust bearing shells.
Refer to the specifications: the pressure in the radial bearings should be 0.09–0.13 MPa, while the pressure in the thrust bearings should be 0.024–0.13 MPa. The specific values vary from machine to machine, but the differences are not significant. According to the data, the oil pressure requirement for the thrust bearings is slightly lower than that for the support bearings!
Agree with what was said above; the specific settings still need to be adjusted according to the temperature!
