Axial flow fan stator vane adjustment mechanism
Thread Content
The static blade control mechanism of the catalytic axial flow fan has failed; as part of the unit’s self-protection system, the main fan cannot have its blades adjusted automatically before this failure is resolved, but now it is possible to control them. The unit has been put into automatic operation, and the static blades should be able to be adjusted; however, they can no longer be adjusted and have been set directly to 22 degrees. Everything is reversed. Have you encountered this situation before? Please help analyze it – it’s an emergency
Come and take a look; it’s a good chance to learn something along the way*
I think this phenomenon is somewhat similar to a problem with the ITCC control. By the way, is it an electric actuator or a hydraulic one? How is the operation on site? We are using electric actuators here, and the phenomenon you mentioned has not occurred yet; we are waiting for the results. . .
We are also electric actuators, and there are no issues with on-site operation. All switches work
By the way, the signal that enables automatic adjustment of the engine unit and allows adjustment of the static vanes is a pulse signal
