There are several reasons for the noise of general exhaust pipes, and based on the reasons, targeted measures can be taken:

1. The range hood device is not sturdy enough. If the orientation is not flat, screws are loose, or parts fall off, causing resonance and noise with the bracket during extreme operation, it is necessary to reinstall the range hood or some parts at this moment. It is necessary to make a proper orientation estimation to ensure the correctness of the device.

2. The check valve device is incorrect. For example, if the check valve fails or falls off, resulting in poor smoke exhaust effect, resonance between the oil fume and the check valve in the pipeline, or airflow disturbance, it is easy to produce noise. At this moment, the check valve should be reinstalled or replaced with a new one.

3. The wind turbine blades are deformed and the device is incorrect. Due to long-term use, there is a lot of oil stains attached to the wind turbine, causing imbalance, and perhaps cracking of the blade parts can lead to noise generation. At this time, it is necessary to regularly clean the range hood and replace the wind turbine.

4. The range hood and pipes have not been cleaned for a long time. The oil stains and foreign objects from long-term work are all inside the flue and range hood, and the fan is also unstable, resulting in loud noise. In this way, the range hood and pipes should be cleaned regularly to maintain a normal airflow.

5. The kitchen air is not circulating and closed. This causes poor convection between the range hood and the pipes, preventing negative pressure from forming inside the kitchen, resulting in poor exhaust and noise. Therefore, ventilation in the kitchen is not recommended.

Some measures can also be taken to reduce noise, such as building sound-absorbing bricks on the kitchen wall or top, applying soundproof paint and installing soundproof doors. Of course, you can also choose a noiseless stir fry stove, all of which can reduce noise. One is to lay soundproof bricks on the wall or ceiling, or apply soundproof paint and install soundproof doors, etc; The noise reduction of smoke exhaust pipes can be improved by the company, such as pretending to use soundproof cotton, installing soundproof equipment and silencing systems to reduce the noise of the pipes.
