防止振动和噪音是安装通风管道过程中的一个关键点。
济南通风管道在安装过程中的振动和噪音的预防主要从以下几个方面入手，如下：
Preventing vibration and noise is a key point in the process of installing ventilation pipes. The prevention of vibration and noise during the installation of Jinan ventilation pipeline mainly starts from the following aspects:
安装风机时，应按设计要求或施工规范设置减振装置。风机与通风管之间用软管连接，风机吸入口处的软管安装时应松紧适度，避免因软化、松动而减少进、出风口面积，产生噪音和振动。
When installing the fan, the vibration damping device shall be set according to the design requirements or construction specifications. The fan and the ventilation pipe are connected by hose. The hose at the fan inlet should be installed with appropriate tightness to avoid reducing the area of the air inlet and outlet due to softening and loosening, resulting in noise and vibration.
通风管道的制造、安装及与部件的连接应紧密，不得有漏风现象，以避免漏风噪音。为防止通风管道振动，在各系统通风管道的弯曲处以及与通风机和风口的连接处设置固定支架。
The manufacturing, installation and connection with components of the ventilation duct shall be tight without air leakage to avoid air leakage noise. In order to prevent the vibration of the ventilation duct, fixed supports shall be set at the bend of the ventilation duct of each system and at the connection with the ventilator and the air outlet.
通风管道安装后，需进行漏风试验。根据规定，通风管道的漏风测试采用漏光法和漏风定量测试相结合的方法。漏光法适用于中低压系统的严密性试验。气密性试验适用于中压系统的抽样检查和高压系统的全检。
After the installation of the ventilation duct, the air leakage test is required. According to the regulations, the air leakage test of the ventilation duct adopts the method of combining the light leakage method with the quantitative air leakage test. The light leakage method is applicable to the tightness test of medium and low pressure systems. The air tightness test is applicable to the sampling inspection of the medium pressure system and the full inspection of the high pressure system.
漏光检测是利用光线对小孔的强烈穿透视觉，定性检测系统中通风管道密封性的方法。测试方法是在黑暗的环境下，在一定长度的通风管道内，使用电压不高于36V、功率大于100W的带保护罩的灯泡，从通风管道的一端向另一端缓慢移动。如果在测试过程中可以在不锈钢导管外观察到光线，说明不锈钢导管存在漏气现象，应修复通风管的漏气现象。
Light leakage detection is a method to qualitatively detect the tightness of the ventilation duct in the system by using the strong penetrating vision of light to the small hole. The test method is to use a light bulb with protective cover with voltage not higher than 36V and power greater than 100W in a certain length of ventilation duct in a dark environment, and move slowly from one end of the ventilation duct to the other end. If light can be observed outside the stainless steel conduit during the test, it indicates that there is air leakage in the stainless steel conduit, and the air leakage in the ventilation duct should be repaired.
此外通风管道的材料应根据应用条件综合选择，一些通风管道在技术上需要经常移动，这需要柔性材料，如金属软管、塑料软管和橡胶软管。硬质聚氯乙烯塑料板表面光滑，加工方便，但不耐高温，适用于腐蚀性工业通风和排气系统。更多相关内容就来我们网站

In addition, the materials of ventilation pipes should be comprehensively selected according to the application conditions. Some ventilation pipes need to move frequently in technology, which requires flexible materials, such as metal hose, plastic hose and rubber hose. Rigid polyvinyl chloride plastic plate has smooth surface and convenient processing, but it is not resistant to high temperature. It is suitable for corrosive industrial ventilation and exhaust system. Come to our website for more relevant content //zzlkdzc.com Ask!
