High adjustability: provide a variety of adjustment parameters, can be adjusted according to different working conditions.
Working principle
The working principle of A8516-040 governor mainly includes the following aspects:
Speed measurement: The governor measures the actual speed of the turbine through the speed measurement device.
Deviation comparison: The measured speed is compared with the set value to obtain the speed deviation.
Control signal generation: According to the speed deviation, the corresponding control signal is generated.
Actuator action: The control signal drives the actuator (such as speed regulating valve) to change the steam flow at the turbine inlet.
Closed-loop control: Through the feedback loop, the control signal is constantly adjusted to maintain the stability of the speed.
