Control method for avoiding false alarm of hot metal chip annunciator

摘要: The invention discloses a control method for avoiding false alarm of hot metal chip annunciator. comprises the following steps: connecting normally open contacts two annunciators in series, wherein are independent working an oil return system and discharging arranged at rear supporting points aeroengine; detecting plug parallel circuit checking state annunciator engine on ground; case that alarmenvironment is not destroyed, eliminating whether alarms or by plug, clearing point bearing worn when issues primary alarm, so as to guarantee reliable operation engine. According annunciator, with set series structures designed. function triggers only realized, meanwhile, detection can be completed without decomposition. effectively avoided, accurate warning achieved, reliability areoengine guaranteed.
