Regarding the control system of steam turbines
Thread Content
Dear sea friends, I have recently conducted preliminary research on turbine control systems and gained some insights. If you have any questions, you can discuss them in this post. I hope this can be helpful to fellow travelers who need it.
My intention is for sailors to share and discuss any questions they may have
I’ve just started looking into some materials; I’ll definitely ask if I have any questions
What is the relationship between the turbine’s oil actuator and the throttle valve?
A hydraulic actuator is essentially a cylinder that uses piston movement to adjust the opening degree of the control valve. The wrong throttle receives the control oil pressure signal from the electro-hydraulic converter. The wrong throttle is essentially a spool valve that moves the valve core in response to the different oil pressures generated by the electro-hydraulic converter, thereby changing the path of the oil flowing to the actuator (either upward or downward), and thus causing the actuator to change the position of its piston.
The structure of the incorrect throttle is relatively complex; as an operator, it is sufficient to understand its function.
What is the reason why the quick-shut oil cannot be established? ? ? ? ?
Be more detailed about establishing the operation process
