The range hood machine equipment is not secure.
If the parts of the range hood are uneven, the screws are loose, and the parts fall off, causing vibration and noise between the actual operation and the support frame, it is necessary to reinstall the range hood or parts, and prepare a budget for the cost of the parts to ensure that the machine equipment is appropriate.
The check valve equipment is incorrect.
For example, the common faults and explosions of this product are likely to cause poor actual performance of the smoke exhaust system. Kitchen fumes are likely to cause co vibration in pipelines and this product, or cyclones are likely to be affected, which can easily cause noise. At this point, the check valve should be reinstalled or replaced with a new check valve.
Impeller blade deformation, equipment error.
因为长期性应用，叶轮附带很多的油渍，造成 不平衡。或许一部分叶子破裂会造成 噪声进攻。这时，应按时清理吸油烟机，必需时要拆换叶轮。
Due to long-term application, the impeller comes with a lot of oil stains, causing imbalance. Perhaps a portion of the broken leaves will cause noise attacks. At this point, the range hood should be cleaned on time and the impeller should be replaced if necessary.
