How to better avoid the overload problem of Roots fan
Roots fan in the process of using how to better avoid the overload problem of Roots fan? On this issue Roots fan editorial take you to understand.
1. Due to the structural characteristics of the Roots blower, it is not permitted to return the exhaust gases directly to the inlet of the blower for a long period of time, which would change the temperature of the inlet and thus the safety of the machine . If the return is to be regulated, cooling measures are required.
2. When the Roots blower is operated under rated conditions, the surface temperature of each rolling bearing normally does not exceed 95°C, the temperature of 90% of the lubricating oil in the mailbox does not exceed 65°C, and the vibration speed The large diameter of the bearing section is not greater than 6.3 mm/s. During operation of the blower, always pay attention to the condition of the lubricant and the oil level.
3. Adjustments should be made slowly and the load should be adjusted slowly to guide the rated power. It is not permissible to adjust to the rated load at one time. The rated load is the difference in static pressure between the intake and exhaust ports. When the pressure at the exhaust port is normal, watch for changes in the pressure at the intake port to avoid overloading.
4. During normal fan operation, do not close the intake and exhaust valves completely or allow overload operation.
5. If you want to stop the Roots blower, do not stop it at full load and stop the load gradually before stopping to avoid damaging the machine.
