The protection system monitors steam turbine total train parameters and ensures safety and reliability by the following action: Start-up (optional) provides a safe, reliable fully automatic start-up and will shut down the turbine on any abnormality, Trip valve exerciser allows trip valve stem movement to be confirmed during operation without shutdown, Rotor overspeed monitors turbine rotor speed and will shutdown turbine when maximum allowable speed (trip speed) is attained, Excessive process variable signal monitors all train process variables and will shutdown turbine when maximum value is exceeded. This will release the pin and the trip will be activated. By clicking 'Accept cookies' or by using this website you confirm agreeing to this.

In a matter of seconds, the system completes a partial stroke of the trip valve, and the turbine operators can quickly determine if the trip valve is functioning properly or requires attention. Theme: Machine protection, The API Standard 670 is an industry standard and describes the minimum requirements for a machine protection system (MPS). Solenoid valves are designed to be normally energized to close. At normal speeds, the bolt stays at the same position; however if the speed of the engine rises beyond the pre-set range, the centrifugal force generated by the heavy head of the bolt makes it fly out of the spring and nuts compression pressure.
