Overspeed Trip Systems

Discussion GroupSuggested Topics: Electronic overspeed detection system (speed sensors and logic devices) Number, logic Speed sensing gear Sensor type Electro-hydraulic solenoid valves De-energize to shutdown (API default) Number, location, orientation (vertical or horizontal) Built in position sensor Detection system to alarm on failure of the coil; change online Capable of on-line testing without defeating trip protectionEmergency trip valve(s)/combined trip and throttle valve(s) "Mechanical latch type" and "Oil operated/actuated type" Periodic online exercising - partial stroke test (frequency) Full instrument loop "proof" test (frequency) Valve overhaul (repair shop, overhaul frequency, etc.) Systems with duplicate trip valves arranged in parallel OEM upgrades (i.e. metallurgy, etc.) Non-return valve on extraction turbines Overspeed initiates a signal to close non-return valve Types (spring-loaded hydraulic actuated cylinder; pneumatic actuated cylinder) Valve overhaul (repair shop, overhaul frequency, etc.) Testing Mechanical overspeed system Test frequenc
