To share: air suspension blower common troubleshooting methods

Compared with traditional Roots blowers, air suspension blowers have the characteristics of more efficient energy saving, low noise, reliable

 operation and long-term maintenance. As a result, a large number of factories have gradually adopted air-suspended centrifugal blowers to 

replace Roots blowers.

Today, let's talk about the treatment of common faults in air suspension blowers.

1. Frequency converter communication is abnormal, frequency converter is abnormal or emergency stop;

Solution: The sensor and data communication is abnormal, you need to contact the manufacturer;

2. Exceed the limit value of outlet air pressure;

Solution: Confirm whether the load (pipeline non-destructive, water level, etc.) has increased significantly;

3. Exceed the filter differential pressure limit;

Solution: Clean or replace the suction filter;

4. Exceed the motor temperature limit;

Solution: Take indoor sprinkling, forced ventilation and other cooling measures;

5. Exceed the vibration level limit value;

Solution: Identify external factors such as earthquakes or pipelines;

6. Surge occurs;

Solution: Confirm the performance curve, if running on SURGE line, increase SV;

7. Filter the maximum pressure difference of 95% warning;

Solution: Clean or replace the suction filter;

8. Maximum suction temperature 95% warning;

Solution: Keep indoor air circulating;

9. Vibration sensor Max 95% warning:

Solution: Contact the manufacturer technician;

10. Frequency converter temperature maximum 95% warning;

Solution: Contact the manufacturer technician;

Under the guidance of the national policy of energy conservation and emission reduction, the selection of energy-efficient blowers will become 

a new choice trend, and air suspension blowers will be more and more widely used.
