There are various reasons for the overheating of Roots blowers, including the following aspects and corresponding treatment methods:
reason
1. Fuel tank issue:
Too much, too thick, or too dirty oil in the fuel tank can cause poor heat dissipation.
2. Filter or muffler blockage:
Blockage leads to poor airflow, increasing the load on the fan and causing overheating.
3. Pressure higher than the specified value:
The operating pressure of the fan is too high, exceeding the design standard, resulting in an increase in the body temperature.
4. Excessive wear of impeller:
After the impeller wears out, the clearance increases, resulting in a decrease in fan efficiency and excessive heat generation.
5. Operation speed issue:
The operating speed is too low, causing the belt to slip and resulting in a decrease in fan efficiency, generating heat.
6. Overheating or poor lubrication of bearings:
The lack of lubrication or poor lubrication of bearings leads to increased friction and heat generation.
7. Poor assembly quality:
Insufficient bearing clearance and gear installation clearance during assembly can lead to increased friction and heat generation.
8. Unfavorable working environment:
The working environment temperature of the fan is too high, resulting in high intake temperature and increased body temperature.
9. Inadequate maintenance:
Improper maintenance of the fan, such as inadequate maintenance of oil level, piping system, V-belt, etc., can lead to overheating of the fan.
processing method
1. Adjust the fuel tank:
Reduce the oil level or replace the appropriate lubricating oil to ensure that the oil level in the tank is moderate and the oil quality is good.
2. Clearing blockages:
Regularly clean components such as filters and mufflers to ensure smooth airflow.
3. Adjust pressure:
Check and adjust the working pressure of the fan to ensure it operates within the specified range.
4. Adjust or replace the impeller:
If the impeller is severely worn, the clearance needs to be adjusted or a new impeller needs to be replaced.
5. Adjust the operating speed:
Check and adjust the operating speed of the fan to ensure that the belt does not slip and runs smoothly.
6. Strengthen bearing lubrication:
Regularly clean and lubricate the bearings, and replace the appropriate lubricating oil.
7. Improve assembly quality:
Ensure that the bearing clearance and gear installation clearance meet the design requirements during assembly.
8. Improving the working environment:
Install air conditioning or take other cooling measures in the fan room to reduce the ambient temperature.
9. Strengthen maintenance and upkeep:
Regularly maintain the fan, including cleaning the pipeline, checking the oil level, replacing worn parts, etc.
In summary, there are various reasons for the overheating of Roots blowers, and corresponding measures need to be taken according to specific situations. By strengthening maintenance, adjusting working parameters, and improving the working environment, the temperature of the fan can be effectively reduced, and its operating efficiency and stability can be improved.
