Key Considerations for Commissioning Fire Ventilation Cabinet Centrifugal Fans

Key Considerations for Commissioning Fire Ventilation Cabinet Centrifugal FansSeveral critical factors must be addressed during the commissioning process of fire ventilation cabinet centrifugal fans. 1. Startup Considerations for Fire Ventilation Cabinet Centrifugal Fans. After equipment startup, operation can commence using either full voltage or reduced voltage. However, exercise particular caution when selecting the startup method. Generally, for full-voltage startup, ensure the voltage is 5–7 times the rated current of the fire ventilation cabinet centrifugal fan before normal operation. For reduced-voltage startup, the voltage square must be proportional to the torque ratio. Additionally, low-voltage starting is required in two scenarios: First, when the power grid capacity is insufficient. For power exceeding 11kW, low-voltage starting is recommended. Second, pay close attention to the trial operation of the fire ventilation cabinet centrifugal fan. Furthermore, at least two personnel must be present during trial operation: One to control the power supply, and another to monitor the fan's operation in real-time. If any abnormalities are detected, the fan must be immediately stopped before proceeding to the next debugging stage. Consider the input power of the fire ventilation cabinet centrifugal fan. After confirming normal operation, inspect the input power to verify all equipment functions correctly. Similarly, the input power of the fire ventilation cabinet centrifugal fan must remain within the rated current control range and must not exceed the rated current. Beyond the above precautions, for safety reasons, operators must install valves on the inlet or outlet ductwork of the fire ventilation cabinet centrifugal fan. Close the valves after the fan starts. When the fire ventilation cabinet centrifugal fan is operating normally, gradually open the valves until the required operating conditions are achieved.
