During the maintenance process of Roots blower, common faults and their handling methods mainly include the following aspects:
1、 Insufficient air volume
1. Reason:
The impeller is severely worn and the clearance is too large.
The belt is loose and the speed decreases.
The filter mesh is clogged.
Pipeline leakage.
2. Handling method:
Or replace the impeller.
Adjust or replace the belt to ensure proper tension.
Clean or replace the filter screen.
Check for pipeline leaks.
2、 Fan overheating
1. Reason:
The oil level in the fuel tank is too high or the oil quality is poor.
Filter or muffler blockage.
The operating pressure is higher than the specified value.
Poor ventilation and high indoor temperature.
2. Handling method:
Adjust the oil level to ensure clean oil quality.
Blockage of filters or mufflers.
Reduce the operating pressure to the specified value.
Improve ventilation conditions and reduce indoor temperature.
3、 Bearing malfunction
1. Reason:
The bearings are severely worn and have clearance.
Loose bearings or improper installation.
2. Handling method:
Replace severely worn bearings.
Adjust the bearing clearance to ensure correct installation.
4、 Belt malfunction
1. Reason:
The belt is too tight or too loose.
The belt is severely worn.
2. Handling method:
Adjust the tension of the belt to ensure it is appropriate.
Replace the severely worn belt.
5、 Impact sound
1. Reason:
The gear position is abnormal.
Friction between impeller, casing, and wall panel.
2. Handling method:
Adjust the gear position to ensure correct meshing.
Adjust the gap between the impeller and the wall panel to avoid friction.
6、 Oil leakage issue
1. Reason:
The fuel tank is too high and leaks out through the drain port.
The sealing components are aging or damaged.
The ventilation openings of the wall panels and fuel tanks are blocked.
2. Handling method:
Lower the oil level to the appropriate position.
Replace aging or damaged seals.
Clear the ventilation opening to ensure smooth oil flow.
7、 Vibration
1. Reason:
The balance of the impeller has been disrupted.
There are foreign objects adhering to the impeller.
2. Handling method:
Clean up foreign objects on the impeller and restore balance.
Check and tighten the connecting bolts to ensure the stability of the equipment.
8、 Other faults
1. Sudden increase in exhaust pressure: Check the system to eliminate resistance.
2. Poor cooling: Check if the temperature and flow rate of the cooling water are normal.
3. Overload operation: Identify the cause and reduce the load.
When repairing the Roots blower, make sure that the power is turned off and the rotating part of the blower has stopped to ensure the safety of the maintenance personnel. Meanwhile, daily maintenance and upkeep are also important measures to prevent malfunctions from occurring.
