The failure of Roots blower to produce air may be caused by various reasons. The following are some common reasons and corresponding solutions:
Common reasons
1、 Power issue:
1. The motor power supply phase is reversed, causing the fan to reverse and unable to generate airflow.
2. Loose power cords or unstable power supply voltage can affect the normal operation of the fan.
2、 Mechanical malfunction:
1. The fan impeller is blocked by foreign objects, affecting the airflow.
2. The bearing is burned or worn, causing the fan to operate poorly.
3. The synchronous gear has broken teeth or abnormal clearance, which affects the synchronous rotation of the impeller.
4. There is a problem with the belt transmission system, such as belt breakage or looseness, which leads to a decrease in fan speed.
3、 Pipeline system issues:
1. The air inlet filter is blocked, affecting the entry of gas into the fan.
2. The valve of the outlet pipeline is not open, resulting in the inability to discharge gas.
3. Pipeline water accumulation or blockage at bends increases system resistance.
4、 Abnormal system resistance:
1. The actual system resistance exceeds the rated pressure of the fan, causing the fan to malfunction.
2. The increase in altitude leads to a decrease in actual air volume, requiring re selection or pressure compensation.
5、 Other factors:
1. Improper setting of fan parameters, such as mismatched speed, pressure, and other parameters.
2. The wind turbine has not been maintained for a long time, resulting in component wear or failure.
solution
1、 Check the power supply:
1. Confirm if the motor power phase is correct and adjust the three-phase line sequence.
2. Check if the power cord is securely connected and if the power supply voltage is stable.
2、 Troubleshooting mechanical faults:
1. Clean the foreign objects on the fan impeller to ensure smooth airflow.
2. Check the condition of the bearings and synchronous gears, and replace them promptly if they are damaged.
3. Adjust the belt drive system to ensure that the belt tension is moderate.
3、 Check the pipeline system:
1. Clean the air inlet filter to ensure smooth gas flow into the fan.
2. Confirm that the outlet pipeline valve is open and there is no blockage.
3. Pipeline water accumulation and blockage at bends reduce system resistance.
4、 Adjust system parameters:
1. Use a U-shaped differential pressure gauge to measure the actual system resistance, and adjust it if it exceeds the rated pressure of the fan.
2. Re select or perform pressure compensation based on altitude changes.
5、 Regular maintenance and upkeep:
1. Regularly maintain the Roots blower and check the wear and tear of its components.
2. Timely replace worn or faulty components to ensure the normal operation of the fan.
