1、通風管道加工安裝時,根據(jù)設(shè)計要求或施工規(guī)范要求,設(shè)置減振裝置。

1. During the processing and installation of ventilation pipes, vibration damping devices shall be set according to the design requirements or construction specifications.

2、通風管道加工安裝采用軟管連接,風機吸入口的軟管鍍鋅螺旋風管加工安裝應適度擰緊,避免因軟連接過松而造成噪音和振動,減少進出口面積。

2. The ventilation duct shall be processed and installed with hose connection. The galvanized spiral air duct at the fan inlet shall be properly tightened to avoid noise and vibration caused by loose soft connection and reduce the area of inlet and outlet.

3、制作鍍鋅螺旋風管、鍍鋅螺旋風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. The galvanized spiral air duct shall be manufactured, processed, installed and connected with components, and shall be tightly connected without air leakage and noise.

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

4. In order to prevent the vibration of the processing and installation of the galvanized spiral air duct, the turning and fixing bracket of the processing and installation of the galvanized spiral air duct of each system are set at the connection of the fan and the air outlet.

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

Air leakage test for processing and installation of galvanized spiral air duct: after processing and installation of galvanized spiral air duct, air leakage test shall be conducted. According to the specification, the air leakage test for the processing and installation of galvanized spiral air duct adopts the combination of the light leakage method and the quantitative test of the air leakage test. The light leakage method is applicable to the middle. Check the tightness of the low-voltage system; The air leakage test is applicable to the sampling inspection of the medium-voltage system and the overall inspection of the high-voltage system.

鍍鋅螺旋風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)鍍鋅螺旋風管加工安裝嚴密性的方法。試驗方法是在一定長度的鍍鋅螺旋風管加工安裝上,在黑暗的環(huán)境下,在鍍鋅螺旋風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,并修復螺旋管的泄漏點。

Light leakage method for processing and installation of galvanized spiral air duct The light leakage method is a method to qualitatively detect the tightness of the processing and installation of galvanized spiral air duct of the system by using the strong penetration of light to the small hole. The test method is to use a voltage of not more than 36 V and a power of 100W in the processing and installation of galvanized spiral air duct with a certain length, and in the dark environment, the bulb with protective cover moves slowly from one end of the spiral duct to the other end. If the light outside the spiral tube can be observed during the test, it indicates that the spiral tube has a leakage point, and repair the leakage point of the spiral tube.

系統(tǒng)鍍鋅螺旋風管加工安裝漏光檢測采用分段檢測,總結(jié)分析方法:被測系統(tǒng)鍍鋅螺旋風管加工安裝不允許多條縫明顯漏光,低壓系統(tǒng)鍍鋅螺旋風管加工安裝每10米接縫不超過2個漏光點,100米接縫平均不超過16個;中壓系統(tǒng)鍍鋅螺旋風管加工安裝每10個接縫,漏光點不超過1個,100米接縫平均不超過8個。

The light leakage detection for the processing and installation of the galvanized spiral air duct of the system adopts sectional detection, and the summary and analysis method: the processing and installation of the galvanized spiral air duct of the system under test shall not allow multiple seams to have obvious light leakage, and the processing and installation of the galvanized spiral air duct of the low-voltage system shall not exceed 2 light leakage points every 10 meters, and the average of the 100 meters of joints shall not exceed 16; For the processing and installation of galvanized spiral air duct of medium pressure system, there shall be no more than 1 light leakage point for every 10 joints, and no more than 8 joints for 100 meters on average.
