Application Scenarios
Widely applied in industrial steam turbines, utility turbine generators, and turbo-expanders across sectors such as oil and gas, petrochemicals, metallurgy, and municipal boiler heating.
Performance Parameters
- Operating Temperature: Reliable operation in ambient temperatures from 0°C to 60°C.
- Humidity Tolerance: Withstands up to 60% relative humidity (non-condensing).
Material Composition
Constructed from a series of high-reliability printed circuit boards housed in a rugged, module-style metal enclosure designed for secure integration into control panels.
Structural Characteristics
Features a control-room mounting form factor with a front-facing operator interface. The modular design allows for easy access to internal components during maintenance.
Working Principle
The controller continuously samples turbine parameters via analog and digital inputs. Its microprocessor executes control algorithms to calculate the required valve position and outputs precise electrical signals to hydraulic actuators, maintaining the desired speed or load setpoint.
Installation Requirements
Must be mounted in a control panel with adequate ventilation to dissipate heat. Ensure the operating environment remains within the specified temperature and humidity limits to prevent electronic degradation.
Usage Precautions
- Always use the designated programming mode when altering control parameters to prevent unintended turbine behavior.
- Regularly back up the controller’s configuration data to external media.
- Ensure all electrical connections are properly grounded to prevent signal interference.
