Taking Roots blower as an example, some basic troubleshooting methods are explained:
1, using the elimination method, first disassemble the air outlet to distinguish whether the motor and blower are normal. If the motor is abnormal, repair the motor first. If the motor is normal, it can be confirmed that the blower is abnormal;
2. If the air outlet is removed and the fan and motor are normal, it is the problem of checking the pipeline valve;
3. The abnormal parts of the fan can be judged from the beginning through the noise changes during fault and normal use. For example, the external part can be handled by itself, such as loose belt, aging, loose base or loose connecting screws, locking and strengthening;
4. If the sound inside the blower is abnormal, identify whether it is a bearing or a foreign body. If foreign objects enter, please remove the air inlet and air outlet and clean them. If the bearing collides with the impeller, please find a professional maintenance person to disassemble it for maintenance. Private maintenance may damage the equipment.
