Common troubleshooting methods for air suspension blowers

Thread Content

Compared with traditional Roots blowers, air-suspended centrifugal blowers are more efficient, energy-saving, low-noise, reliable in operation, and require no maintenance for a long time. As a result, a large number of factories gradually use air suspension centrifugal blowers to replace Roots blowers. Its principle structure and advantages have been introduced before. Today we will talk about how to deal with common faults of air suspension blowers. 1. Inverter communication abnormality, inverter abnormality or emergency stop ； Solution: It indicates that the sensor and data communication are abnormal and you need to contact the manufacturer. ； 2. Exceeding the outlet pressure limit value ； Solution: Confirm whether the load (pipeline damage, water level, etc.) has increased significantly ； 3. Exceeding the filter pressure difference limit value ； Solution: Clean or replace suction filter ； 4. Exceeds the motor temperature limit value ； Solution: Take cooling measures such as indoor watering and forced ventilation ； 5. Vibration level limit exceeded ； Solution: Confirm factors causing vibrations from the outside such as earthquakes or pipelines ； 6. Surge occurs ； Solution: Confirm performance curve, if running on SURGE line, increase SV ； 7. Warning for maximum filtration pressure difference of 95% ； Solution: Clean or replace suction filter ； 8. Warning for maximum suction temperature of 95% ； Solution: Maintain indoor air circulation ； 9. Vibration sensor maximum 95% warning: Solution: Contact the manufacturer's technician ； 10. Warning for maximum inverter temperature of 95% ； Solution: Contact the manufacturer's technician ； exist * * Under the guidance of energy conservation and emission reduction policies, choosing high-efficiency and energy-saving blowers will become a new selection trend, and air suspension centrifugal blowers will be more and more widely used.
