The Roots blower has malfunctioned and failed to turn, causing concern.
The failure of the Roots blower to operate may be caused by various reasons. The following are some possible reasons and corresponding solutions:
1、 Possible reasons
1. Foreign object stuck:
Large particles enter the fan chamber, blocking the gaps between various parts and preventing the fan from rotating.
2. Impeller issue:
The impeller is damaged or interlocked, causing the fan to jam.
3. Gear damage:
Gear wear or excessive meshing area can prevent the gear from rotating, thereby affecting the rotation of the fan.
4. Bearing damage:
Bearing wear or jamming can cause changes in the clearance between the impeller, casing, and wall panels, resulting in friction and preventing the fan from rotating.
5. Rusted and stuck:
The wind turbine has been idle for a long time, causing rusting. The impeller and the wall panel or casing rust together, or the rust falls off in large areas, resulting in the impeller getting stuck.
6. Component deformation:
Due to insufficient strength of the components or deformation caused by prolonged use, the gaps between the components are damaged, resulting in the fan getting stuck.
7. Motor malfunction:
Malfunctions such as motor burnout and circuit abnormalities prevent the fan from rotating.
8. Process medium influence:
The medium contains a large amount of dust and water vapor, and the dust adsorbs on the surface of the shell and rotor, reducing the gap and causing friction or even jamming of the rotor.
2、 Solution method
1. Cleaning foreign objects:
Clean the foreign objects inside the cavity, and check the gap between the impellers and the reason for the foreign objects falling in to avoid the recurrence of the fault.
2. Check and replace the impeller:
Disassemble and inspect the casing, replace damaged impellers.
3. Replacing gears:
Check the tooth flank clearance, replace worn gears, and use red lead powder to inspect the contact area of the gear meshing part.
4. Replace bearings:
Check the wear of bearings and replace severely worn bearings in a timely manner.
5. Cleaning rust:
Clean the rust by soaking it in kerosene, rinsing it with gasoline, and adjust the gap.
6. Replace deformed components:
Check and replace deformed components to ensure that the gaps between them meet technical requirements.
7. Check and replace the motor:
Check the operating status of the motor and replace or repair the faulty motor in a timely manner.
8. Regular maintenance:
Regularly maintain the fan, including cleaning dust, checking gaps, replacing worn parts, etc., to reduce the possibility of malfunctions.
In summary, the malfunction of the Roots blower disk may be caused by various reasons, and it needs to be investigated and resolved according to the specific situation. During the investigation process, attention should be paid to the operation to avoid causing personal injury or equipment damage. If the problem is complex or uncertain, it is recommended to hire professional technicians for repair.
