Why Do High-Pressure Centrifugal Blower Motors Experience Overcurrent?

A high-pressure centrifugal blower is a type of fluid-handling machinery that relies on input mechanical energy to increase gas pressure and transport gas. High-pressure centrifugal blowers are widely used in factories, mines, tunnels, cooling towers, vehicles, ships, and buildings for ventilation, dust removal, and cooling. Ventilation and induced draft for boilers and industrial furnaces; cooling and air exchange for air conditioning equipment and household appliances; grain drying and sorting; wind tunnel sources; and Hobakaf expansion and propulsion. 8 Causes of Overcurrent in High-Pressure Centrifugal Blower Motors: 1. The main shaft speed exceeds the rated value. 2. Severe vibration in the bearing housing. 3. Airflow exceeds the specified value or there is a leak in the ductwork. 4. The operating conditions of parallel-connected high-pressure centrifugal blowers have deteriorated. 5. During operation, the inlet (or outlet) duct valve is not locked. 6. The motor input voltage is too low, or there is a single-phase power supply failure. 7. The coupling is misaligned, the rubber ring is too tight, or the clearance is uneven. 8. The gas supplied by the high-pressure centrifugal blower has excessive density, is too cold, or is under excessive pressure.
