Will there be a secondary oil pressure before the turbine starts?

Will there be a secondary oil pressure after the start-up oil pressure is established before starting the turbine? Please help.
Yes! If not, how can the volume be turned up? . . . . . .
First, establish the starting oil pressure, then the quick-shut oil pressure, and finally the secondary oil pressure.
There definitely are. Otherwise, how would one be able to adjust things like oil actuators?
Of course, there is a secondary oil pressure; its range is from 1.5 MPa to 4.5 MPa. Once this oil pressure is established, it remains at 1.5 MPa even when the intake valve is closed.
Agree with the person above! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
The secondary oil pressure ranges from 0.15 to 0.45 MPa, corresponding to a valve opening of 0–100. However, the original poster only mentioned the establishment of startup oil; if the quick-shut oil is not established, then there will be no secondary oil pressure. This is because the oil that enters the electro-hydraulic converter is the quick-shut oil, and it is after conversion that the secondary oil pressure is generated. If the quick-shut oil is established, then secondary oil pressure will be present. These are just my personal opinions
Agree with the person above; it’s completely correct. The secondary oil pressure range is 0.15–0.45 MPa, corresponding to a valve opening of 0–100.
There must be one; without secondary oil pressure, how can the hydraulic actuator adjust the opening degree of the speed control valve?
Only after the quick-shut oil is established can the electro-hydraulic converter be supplied with high-pressure oil. If the starting oil is available but the quick-shut oil has not been established, then the secondary oil lacks a power source.
There definitely are; just give it a try. I’ve used our 3 machines to drive over 50 cars already!
