4.Installation and maintenance

Installation and connection:

Install the speed governor to the control cabinet or operating platform near the steam turbine.

Connect the sensors and actuators according to the instructions to ensure correct signal transmission and action execution.

Power supply and communication:

Provide the required power to the speed governor.

Connect the speed governor to the host computer or monitoring system using the appropriate communication interface.

Ensure the correct configuration and parameter setting of the communication interface.

Parameter setting and control program writing:

Set the control parameters of the speed governor according to the turbine model,operation requirements and control system requirements.

Use supported programming languages(such as C++,C#,etc.)to write the control program.

Download the written control program to the speed governor,and debug and test it.

Operation and maintenance:

Start the turbine and control system,and run the speed governor.

During operation,pay close attention to the operating status and parameter changes of the speed governor.

Adjust and control the speed and output power of the turbine in time.

Regular maintenance and care are also important measures to ensure the normal operation and service life of the speed governor.
