空气是人们生活中很重要的，缺少了空气人们就会感到窒息活不下去，空气中的氧气也是维持人生命很基本的要素，所以要时刻保持着室内的通风，满足人们对于氧气的需求，这也是浙江通风管道对于人们生活的作用。在人群密集或者相对于封闭的空间中空气的不流通、呼出的二氧化碳等等都会使得空气不流通，所以要时刻记得通风，尤其是在工厂中更要注意。
Air is very important in people's lives. Without it, people will feel suffocated and unable to survive. Oxygen in the air is also a fundamental factor in maintaining human life. Therefore, it is necessary to maintain indoor ventilation at all times to meet people's demand for oxygen. This is also the role of ventilation ducts in people's lives in Zhejiang. The lack of air circulation, exhaled carbon dioxide, and other factors in densely populated or enclosed spaces can cause air circulation, so it is important to always remember to ventilate, especially in factories.
1、风管安装前未清除内部杂物
1. Failure to remove internal debris before installing the air duct
风管安装前应清除内、外杂物，并做好清洁和成品，施工后及时封堵管口，如不清除杂物，将会造成系统阻力加大，严重时堵塞过滤网和管道。
Before installing the air duct, the internal and external debris should be removed, and the cleaning and finished products should be done well. After construction, the pipe mouth should be sealed in a timely manner. If the debris is not removed, it will increase the system resistance, and in severe cases, block the filter screen and pipeline.
2、风管系统安装后不按规定作漏光、漏风检查和试验
2. Failure to conduct light and air leakage checks and tests as required after the installation of the air duct system
漏光或漏风量测定是对通风空调施工质量的一项检验措施，必需严格按要求规范进行检验，若风管系统安装后不按规定作漏光、漏风检查型槽模具 一次性止血带 保定水处理设备 一次性止血带 保定空压机 北京真空泵和试验，可能会造成系统大量漏风，使整个系统和项目工程达不到使用要求，增加不必要的返工和浪费，同时也浪费了能源。
Measurement of light or air leakage is an inspection measure for the quality of ventilation and air conditioning construction, and it is necessary to strictly follow the required specifications for inspection. If the air duct system is not inspected and tested for light or air leakage according to regulations after installation, it may cause a large amount of air leakage in the system, making the entire system and project process unable to meet the usage requirements, increasing unnecessary rework and waste, and also wasting energy.
