During long-term use, it is inevitable that some faults and problems may occur with the Three Leaf Roots blower. The following is a detailed guide for the maintenance of the Three Leaf Roots blower:
1、 Repair steps
1. Inspection and Diagnosis
By observing the sound, vibration, and temperature of the Roots blower during operation, the type and location of the fault can be preliminarily determined.
After shutdown, conduct a detailed inspection of various components of the Roots blower, including impellers, bearings, seals, filters, etc. Check whether the impeller is worn or deformed, whether the bearings are damaged, whether the seals are aged or damaged, and whether the filter is clogged.
2. Disassemble the fan
Separate the coupling, remove the foot screws, and lift out the fan.
Remove the coupling and end cover, and sequentially disassemble the gear, bearing, bearing seat, and air seal.
Remove the wall panel (the fan should be lifted up when removing the wall panel) and lift out the rotor.
3. Cleaning components
Clean the disassembled components to remove oil stains, dust, and impurities. When cleaning, it is important to use appropriate cleaning agents and tools to avoid damaging the components.
4. Replace damaged components
According to the inspection results, replace worn or damaged components such as impellers, bearings, seals, etc. During the replacement process, it is important to ensure that the model and specifications of the new component are consistent with those of the original component.
5. Adjust the gap
Check and adjust the gaps between impellers, impellers and wall panels, impeller tops and casings, and other components. Ensure that the gap is within the specified range to ensure the normal operation and performance of the fan.
6. Reinstall and debug
After replacing the components, assemble them in the reverse order of disassembly. During assembly, attention should be paid to the assembly position and sequence of each component to avoid deviations.
Adjust the assembled fan, including the balance of the impeller and the clearance of the bearings. Ensure that the fan runs smoothly without vibration and that the coordination between various components is good.
7. Trial operation
After completing assembly and adjustment, conduct a trial run. Observe whether the fan runs smoothly, without any abnormal sounds or vibrations.
During the trial operation, check the temperature and sealing condition of each component. Ensure that the temperature and sealing condition of each component of the fan meet the requirements under normal operation.
2、 Common faults and solutions
1. The fan noise is too loud
Possible reasons: damaged or worn fan impeller, worn bearings, loose fan shaft, dust or foreign object blockage.
Solution: Replace the impeller, replace the bearings, tighten the fan shaft screws, and regularly clean and remove dust.
2. Unstable operation of the fan
Possible reasons: The gap between the fan impeller and the housing is too large, the impeller itself is worn, and the bearings are damaged.
Solution: Adjust the gap between the impeller and the housing again or replace the impeller and bearings.
3. The fan temperature is too high
Possible reasons: Excessive wear of internal components of the fan, increased operating resistance, and blocked radiator.
Solution: Clean the fan, replace severely worn components, and inspect and clean the radiator.
4. Unstable air pressure
Possible reasons: Damaged air pressure sensor, loose fan frame, and air leakage in the pipeline.
Solution: Replace the air pressure sensor, tighten the screws of the fan frame, check and repair the air leakage.
3、 Daily maintenance and upkeep
1. Regular cleaning
Regularly clean the dust and debris inside the fan to maintain its cleanliness.
2. Lubrication and maintenance
Lubricate and maintain easily worn components such as bearings to extend their service life.
3. Check for wear and tear
Regularly check the wear of the fan impeller and other components, and replace severely worn parts in a timely manner.
4. Operating standards
When operating the Roots blower, follow the operating procedures and requirements. Avoid overloading and overspeed operation to ensure that the fan operates in a suitable environment.
Through the above maintenance guidance and daily maintenance measures, the service life of the Three Leaf Roots blower can be effectively extended, ensuring the normal operation of industrial production.
