1. When processing and installing galvanized spiral air ducts for fans, vibration reduction devices should be installed according to design requirements or construction specifications.

2、風(fēng)機.鍍鋅螺旋風(fēng)管加工安裝采用軟管連接，風(fēng)機吸入口的軟管鍍鋅螺旋風(fēng)管加工安裝應(yīng)適度擰緊，避免因軟連接過松而造成噪音和振動，減少進(jìn)出口面積。

2. The processing and installation of fans and galvanized spiral air ducts use hose connections. The hose at the fan suction port for galvanized spiral air duct processing and installation should be moderately tightened to avoid noise and vibration caused by loose soft connections and reduce the inlet and outlet area.

3、制作鍍鋅螺旋風(fēng)管.鍍鋅螺旋風(fēng)管加工安裝及與部件連接，連接緊密，無漏氣現(xiàn)象，避免漏氣噪聲。

3. Produce galvanized spiral air ducts. Process and install galvanized spiral air ducts and connect them to components tightly, without air leakage, to avoid air leakage noise.

4、為了防止鍍鋅螺旋風(fēng)管加工安裝的振動，在每個系統(tǒng)鍍鋅螺旋風(fēng)管加工安裝的轉(zhuǎn)彎處.固定支架設(shè)置在通風(fēng)機與風(fēng)口的連接處。

4. In order to prevent vibration during the processing and installation of galvanized spiral air ducts, a fixed bracket is set at the connection between the ventilation fan and the air outlet at the turning point of each system's galvanized spiral air duct processing and installation.

鍍鋅螺旋風(fēng)管加工安裝漏風(fēng)試驗：鍍鋅螺旋風(fēng)管加工安裝完畢后，應(yīng)進(jìn)行漏風(fēng)試驗。根據(jù)規(guī)范，鍍鋅螺旋風(fēng)管加工安裝的漏風(fēng)試驗采用漏光法和漏風(fēng)試驗定量試驗相結(jié)合，漏光法適用于中間.檢查低壓系統(tǒng)的嚴(yán)密性;漏風(fēng)試驗適用于中壓系統(tǒng)的抽檢和高壓系統(tǒng)的檢測。

Galvanized spiral air duct processing and installation air leakage test: After the processing and installation of galvanized spiral air duct is completed, an air leakage test should be conducted. According to the specifications, the air leakage test for the processing and installation of galvanized spiral air ducts adopts a combination of light leakage method and quantitative air leakage test. The light leakage method is suitable for checking the tightness of the low-voltage system in the middle; The air leakage test is applicable to spot checks of medium voltage systems and comprehensive inspections of high voltage systems.

鍍鋅螺旋風(fēng)管加工安裝漏光法檢測漏光法檢測是一種利用光線對小孔的強透視力來定性檢測系統(tǒng)鍍鋅螺旋風(fēng)管加工安裝嚴(yán)密性的方法。試驗方法是在一定長度的鍍鋅螺旋風(fēng)管加工安裝上，在黑暗的環(huán)境下，在鍍鋅螺旋風(fēng)管加工安裝中使用不超過36的電壓V.功率在100W上述帶有保護(hù)罩的燈泡從螺旋管的一端緩慢移動到另一端。如果在試驗過程中可以觀察到螺旋管外的光線，則表明螺旋管有泄漏點，并修復(fù)螺旋管的泄漏點。

Galvanized spiral air duct processing and installation leak detection method is a method that uses the strong transmittance of light to small holes to qualitatively detect the tightness of the galvanized spiral air duct processing and installation system. The test method is to use a voltage of no more than 36 V and a power of 100W on a certain length of galvanized spiral air duct during processing and installation in a dark environment. The bulb with a protective cover is slowly moved from one end of the spiral duct to the other end. If the light outside the spiral tube can be observed during the experiment, it indicates that there is a leakage point in the spiral tube, and the leakage point of the spiral tube should be repaired.
