防止鍍鋅風(fēng)管震動和噪音的方法。防止震動和噪音是安裝全過程中的關(guān)鍵步驟。安裝全過程中，鍍鋅風(fēng)管的震動和噪音防止主要從以下幾個方面入手:
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風(fēng)扇安裝時，應(yīng)根據(jù)設(shè)計要求或施工規(guī)范設(shè)置減振裝置。
① When installing the fan, the vibration damping device shall be set according to the design requirements or construction specifications.
②風(fēng)機(jī)和鍍鋅風(fēng)管的聯(lián)接采用軟管聯(lián)接，風(fēng)機(jī)吸入口處的軟管安裝應(yīng)適度松緊，避免因軟接過松而降低進(jìn)出風(fēng)口面積而產(chǎn)生噪音和震動。防止鍍鋅風(fēng)管震動和噪音的方法。
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鍍鋅風(fēng)管制造、安裝和與部件聯(lián)接，聯(lián)接嚴(yán)密，無漏風(fēng)現(xiàn)象，避免漏風(fēng)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為了防止鍍鋅風(fēng)管震動，在各系統(tǒng)鍍鋅風(fēng)管的轉(zhuǎn)彎處，與通風(fēng)機(jī)和風(fēng)口的連接處設(shè)置固定支架。鍍鋅風(fēng)管漏風(fēng)量測試鍍鋅風(fēng)管安裝后，需要進(jìn)行漏風(fēng)量測試。根據(jù)規(guī)范，鍍鋅風(fēng)管的漏風(fēng)量測試采用漏光法定性和漏風(fēng)量測試定量測試相結(jié)合的方式，適用于中低壓系統(tǒng)的嚴(yán)密性測試；漏風(fēng)量測試適用于中壓系統(tǒng)的抽檢和高壓系統(tǒng)的全部檢測。防止鍍鋅風(fēng)管震動和噪音的方法。
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.
