The principle that should be paid attention to when designing a local exhaust cover
1. The local exhaust cover should be surrounded as possible or close to harmful passive, so that the harmful and passive limit and smaller local space should be surrounded.The range of aspiration should be reduced as much as possible for easy capture and control.
2. The direction of the inhalation airflow of the exhaust hood should be consistent with the direction of pollution air.
3. The contaminated inhalation airflow is not allowed to pass through the respiration area of ??people.When designing, you must fully consider the position and scope of the operator.
4. The exhaust hood should strive to be simple structure and low cost, which is easy to install and maintain.
5. The configuration of the local exhaust cover should be coordinated with the production process, and strive not to affect the process operation.
6. It is necessary to avoid and weaken the impact of interference and interference airflow, wearing air, and sending atmospheric flow on inhalation airflow.
The above is the principle that you should pay attention to when designing a local exhaust cover. I hope that the above content can help everyone. Thank you for your viewing and support. In the later period, more information will be sorted out. Please pay more attention to us ——
