防止鍍鋅風(fēng)管震動(dòng)和噪音的方法。防止震動(dòng)和噪音是安裝全過(guò)程中的關(guān)鍵步驟。安裝全過(guò)程中，鍍鋅風(fēng)管的震動(dòng)和噪音防止主要從以下幾個(gè)方面入手:

Methods to prevent vibration and noise from galvanized air ducts. Preventing vibration and noise is a crucial step throughout the installation process. During the entire installation process, the vibration and noise prevention of galvanized air ducts mainly focus on the following aspects:

①風(fēng)扇安裝時(shí)，應(yīng)根據(jù)設(shè)計(jì)要求或施工規(guī)范設(shè)置減振裝置。

① When installing fans, vibration damping devices should be set up according to 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(guò)松而降低進(jìn)出風(fēng)口面積而產(chǎn)生噪音和震動(dòng)。防止鍍鋅風(fēng)管震動(dòng)和噪音的方法。

② The connection between the fan and the galvanized air duct adopts a flexible hose connection. The installation of the flexible hose at the fan inlet should be moderately loose to avoid noise and vibration caused by the reduction of the inlet and outlet area due to loose soft connections. Methods to prevent vibration and noise from galvanized air ducts.

③鍍鋅風(fēng)管制造、安裝和與部件聯(lián)接，聯(lián)接嚴(yán)密，無(wú)漏風(fēng)現(xiàn)象，避免漏風(fēng)噪音。

③ Galvanized air duct manufacturing, installation, and connection with components, with tight connections and no air leakage, to avoid air leakage noise.

④為了防止鍍鋅風(fēng)管震動(dòng)，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(cè)試鍍鋅風(fēng)管安裝后，需要進(jìn)行漏風(fēng)量測(cè)試。根據(jù)規(guī)范，鍍鋅風(fēng)管的漏風(fēng)量測(cè)試采用漏光法定性和漏風(fēng)量測(cè)試定量測(cè)試相結(jié)合的方式，適用于中低壓系統(tǒng)的嚴(yán)密性測(cè)試；漏風(fēng)量測(cè)試適用于中壓系統(tǒng)的抽檢和高壓系統(tǒng)的全部檢測(cè)。防止鍍鋅風(fēng)管震動(dòng)和噪音的方法。

④ In order to prevent vibration of galvanized air ducts, fixed brackets are installed at the turning points of galvanized air ducts in each system, and at the connection points with ventilation fans and air vents. After the installation of galvanized air ducts, a leakage test is required. According to the specifications, the leakage test of galvanized air ducts adopts a combination of leakage detection and quantitative testing, which is suitable for the tightness test of medium and low voltage systems; The air leakage test is applicable to the sampling inspection of medium pressure systems and all inspections of high pressure systems. Methods to prevent vibration and noise from galvanized air ducts.
