The installed capacity of the cabinet type centrifugal fan box accounts for 30% to 40% of the total power of the production line. Strengthening the maintenance and upkeep of the online centrifugal fan is particularly important, especially for the severe wear of the fan impeller, which causes the fan rotor to be unbalanced, resulting in an increase in the amplitude of the entire fan and seriously affecting the normal operation of production. Therefore, how to perform dynamic balancing and eliminate unbalanced factors for fans on construction sites? In years of fan maintenance and management work, the author has summarized an effective and simple drawing method, namely the use of drawing method, to find the light spot position of the impeller and add counterweights at the light spot position to clear the imbalance of the fan.
Cabinet style centrifugal fan cases have gradually been widely used and have become one of the main equipment in processes such as ironmaking and sintering. However, in our application process, we often encounter vibration exceeding the standard due to blade wear and deformation, which affects the normal operation of the fan and even causes production line shutdown. The cabinet centrifugal fan case must be operated correctly according to the above instructions during application, so as to fully demonstrate its performance and bring us higher benefits.
