　　Installation position: The installation of the air duct should meet the design requirements, with accurate positioning and firm fixation.
　　连接严密性：风管与设备、管道的连接应严密，无漏风现象。
　　Tightness of connection: The connection between the air duct and the equipment or pipeline should be tight without any air leakage.
　　支吊架设置：风管支吊架的设置应合理，满足风管承重和热膨胀的要求。
　　Support and hanger installation: The installation of air duct support and hanger should be reasonable and meet the requirements of air duct load-bearing and thermal expansion.
　　四、密封性测试
　　4、 Sealing test
　　测试设备：密封性测试应采用专业设备，测试压力和时间应符合规范要求。
　　Testing equipment: Professional equipment should be used for sealing testing, and the testing pressure and time should meet the requirements of the specifications.
　　漏点处理：测试过程中发现的漏点应及时进行修补，并重新测试直至合格。
　　Leakage handling: Leakage points discovered during the testing process should be repaired in a timely manner and retested until they are qualified.
　　五、清洁度检查
　　5、 Cleanliness check
　　安装前清洁：风管系统在安装前，应对材料进行清洁，确保无灰尘、油污等污染物。
　　Cleaning before installation: Before installing the air duct system, the materials should be cleaned to ensure that there are no pollutants such as dust and oil stains.
　　安装过程清洁：安装过程中应采取措施，防止污染物进入风管内部。
　　Cleaning during installation: Measures should be taken during the installation process to prevent pollutants from entering the interior of the air duct.
　　安装后检查：系统安装完成后，应对风管内部进行清洁度检查，确保达到使用要求。
　　After installation inspection: After the system installation is completed, the cleanliness inside the air duct should be checked to ensure that it meets the requirements for use.
　　六、性能测试
　　6、 Performance testing
　　测试内容：风管系统在投入使用前，应进行性能测试，包括风量、风压、噪音等指标。
　　Test content: Before putting the air duct system into use, performance tests should be conducted, including indicators such as air volume, air pressure, and noise.
　　测试人员：性能测试应由专业人员进行，测试结果应满足设计要求和使用标准。
　　Testers: Performance testing should be conducted by professionals, and the test results should meet the design requirements and usage standards.
　　调整或更换：对于不符合性能要求的风管系统，应及时进行调整或更换，直至满足要求。
　　Adjustment or replacement: For air duct systems that do not meet performance requirements, they should be adjusted or replaced in a timely manner until the requirements are met.
　　七、其他注意事项
　　7、 Other precautions
　　验收记录：风管系统的验收过程应有详细的记录，包括材料、加工、安装、测试等各个环节。
　　Acceptance Record: The acceptance process of the air duct system should have detailed records, including materials, processing, installation, testing, and other aspects.
　　验收报告：验收完成后，应编制验收报告，报告中应详细描述验收过程、结果及存在的问题。
　　Acceptance report: After the acceptance is completed, an acceptance report should be prepared, which should describe in detail the acceptance process, results, and existing problems.
　　签字确认：验收报告应由项目负责人、监理工程师和施工单位共同签字确认。
　　Signature confirmation: The acceptance report should be jointly signed and confirmed by the project leader, supervising engineer, and construction unit.
　　综上所述，风管验收过程中需要关注的细节问题涵盖了材料、加工、安装、测试等多个方面。只有严格按照规范和标准执行验收程序，才能确保风管系统的质量和安全性。
　　In summary, the details that need to be paid attention to during the acceptance process of air ducts cover multiple aspects such as materials, processing, installation, and testing. Only by strictly following the specifications and standards in the acceptance procedures can the quality and safety of the air duct system be ensured.
