And finally, when the main helium fan is stopped, acquiring flow change in the deceleration process, and comparing the flow change with a flow value when the fan baffle is in an active full-open position to confirm whether the fan baffle is in an inactive closing state.
It should be noted that, before the fan baffle is located at the "passive on-off position" and is not fully opened, under the same rotation speed of the main helium fan, the main helium fan flow rate of the fan baffle in the "passive on-off position" state is slightly smaller than the main helium fan flow rate of the fan baffle in the "active fully opened" state, so that whether the fan baffle is in the passive on state can be determined by comparing the flow rate value of the rotation speed corresponding to the passive fully opened position with the flow rate of the "active fully opened position".
