describe
The Steam 5X00497G01 turbine is used in many power plants. an electric appliance
The load of the steam turbine generator fluctuates with changes in electricity
Increase or decrease in consumption. Digital Electrohydraulic (DEH) Control
The system provides steam turbine control to regulate steam 5X00497G01 turbine shaft speed
Respond to different generator loads. A very powerful force is
Valves need to be moved on large turbines. Therefore, the insertion device is
It is required between the DEH control system and the control valve.
The 5X00497G01 Ovation servo driver module provides an interface between Ovations
Controller and electro-hydraulic servo valve actuator. Each controlled turbine
The valve is connected to an electro-hydraulic actuator (servo motor). The servo motor is
Pistons for fluid operation. High pressure hydraulic fluid enters the piston
The cylinder is regulated by a smaller pilot valve. Pilot valve passes through hydraulic fluid
Under the piston to lift the piston and controlled valve, or to transfer hydraulic fluid
Go to the upper side of the piston to lower it and the controlled valve.
The valve position setpoint is maintained by the 5X00497G01 Ovation servo driver electronic device
modular. Ovation controllers typically change setpoints through a 1/0 bus.
Inside the electronic module, the microcontroller provides closed-loop proportional control
Positive integral (PI) control for real-time valve position control.
The valve position setpoint causes the servo driver module to generate an output
The control signal that drives the coil of the electro-hydraulic servo valve actuator. this
The feedback loop is closed, and the position measurement of 5X00497G01 valve is from
DC-LVDT or AC-LVT installed on the valve stem. The electronic module will be connected to two electrohydraulic (EH) actuators
Field. This module provides two independent channels that are electrically isolated
From each other.
5X00497G01 Westinghouse Base Control Unit
Emerson 5X00497G01 BASE COOLER, which is a miniature DC motor and a set of local precision motors
The gear reduction device is assembled as a whole, and the output speed of the DC servo motor is reduced by the reduction mechanism. Therefore, this
The characteristic of this type of motor is that it can output extremely low speeds (up to a few tenths of a revolution per minute) and operate at low speeds
The line is very smooth.
