防止镀锌风管震动和噪音的方法。防止震动和噪音是安装全过程中的关键步骤。安装全过程中,镀锌风管的震动和噪音防止主要从以下几个方面入手:
Methods to prevent vibration and noise of galvanized air duct. Preventing vibration and noise is a key step in the whole installation process. Starting with the following aspects of noise prevention during galvanizing and air duct installation:
①风扇安装时,应根据设计要求或施工规范设置减振装置。
① When installing the fan, the vibration damping device shall be set according to the design requirements or construction specifications.
②风机和镀锌风管的联接采用软管联接,风机吸入口处的软管安装应适度松紧,避免因软接过松而降低进出风口面积而产生噪音和震动。防止镀锌风管震动和噪音的方法。
② The connection between the fan and the galvanized air duct adopts hose connection. The hose at the suction inlet of the fan shall be installed with appropriate tightness to avoid noise and vibration caused by reducing the area of the air inlet and outlet due to too loose soft connection. Methods to prevent vibration and noise of galvanized air duct.
③镀锌风管制造、安装和与部件联接,联接严密,无漏风现象,避免漏风噪音。
③ Galvanized air duct shall be manufactured, installed and connected with components. The connection shall be tight without air leakage and avoid air leakage noise.
④为了防止镀锌风管震动,在各系统镀锌风管的转弯处,与通风机和风口的连接处设置固定支架。镀锌风管漏风量测试镀锌风管安装后,需要进行漏风量测试。根据规范,镀锌风管的漏风量测试采用漏光法定性和漏风量测试定量测试相结合的方式,适用于中低压系统的严密性测试;漏风量测试适用于中压系统的抽检和高压系统的全部检测。防止镀锌风管震动和噪音的方法。
④ In order to prevent the vibration of galvanized air duct, a fixed support is set at the corner of galvanized air duct of each system and the connection with ventilator and air outlet. Air leakage test of galvanized air duct after the installation of galvanized air duct, air leakage test is required. According to the specification, the air leakage test of galvanized air duct adopts the combination of light leakage legality and air leakage quantitative test, which is suitable for the tightness test of medium and low voltage system; The air leakage test is applicable to the sampling inspection of medium voltage system and all inspection of high voltage system. Methods to prevent vibration and noise of galvanized air duct.
