Analysis and Preventive Measures of Stuck Exhaust Valve Actuator of a Marine Diesel Engine
There are many reasons why the exhaust valve actuator of marine diesel engine is stuck,including filter failure,particulate matter entering the system,insufficient material hardness,and accuracy is not up to standard,unreasonable design,fatigue fracture string oil is not complete and the installation process is not up to standard and so on.This paper introduces a failure mode of the exhaust valve actuator stuck during the sea trial period due to the incomplete oil string process of diesel engine factory.Through the joint analysis of the supervi-sion team,shipyards,ship owners and manufacturers,we find the reasons,from simple to difficult,from single accidents to no-accidental accidents,and finally solve the problem.It provides reference for the design,manufac-ture and troubleshooting of diesel engine exhaust valve actuator.
