Non-stop wind switch system

Introduction to the structure and characteristics of the AHKJ-1 butterfly valve switching damper horizontal testing damper type non-stop air reversing system: The switching of the system is completed by the non-stop wind turbine monitoring and monitoring system, which controls the butterfly valve to switch the air door and the horizontal test door. The switching steps are as follows: ① During the normal operation of fan 1, the shutdown begins. First, open the horizontal test air door of fan 2 and turn on the backup fan of fan 2 to put it in an idle state. (The so-called idle state refers to the airflow entering from the horizontal test damper and exiting from the air outlet, achieving hot standby before starting up.) ② After the online monitoring unit of the system detects that the second standby fan is operating normally, open the second butterfly valve to switch the air door, close the second horizontal test air door, and at the same time close the butterfly valve switch a…
