1、吸油烟机机器设备不牢固。

1. The range hood machine equipment is not secure.

假如吸油烟机的部位不匀称，螺钉松脱，零件掉下来，使实际操作与支撑架造成共震并造成噪声，这时必须再次安装吸油烟机或零件，而且准备好部位费用预算，以保证 机器设备恰当。

If the parts of the range hood are uneven, the screws are loose, and the parts fall off, causing resonance and noise between the actual operation and the support frame, the range hood or parts must be reinstalled, and a budget for the parts must be prepared to ensure that the machine equipment is appropriate.

2、逆止阀设备是不正确的。

2. The check valve equipment is incorrect.

比如，本产品的常见故障和爆出很有可能造成 排烟系统实际效果不佳。厨房油烟很有可能会在管道和本产品中造成共震，或是气旋很有可能会遭受影响，进而非常容易造成噪声。这时，应再次安装逆止阀或拆换新的逆止阀。

For example, common malfunctions 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 pipes 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.

3、叶轮叶子形变，设备有误。

3. 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 some of the broken leaves will cause noise attacks. At this time, the range hood should be cleaned on time, and if necessary, the impeller should be replaced.
