防止振動和噪音是安裝通風(fēng)管道過程中的一個關(guān)鍵點。
濟(jì)南通風(fēng)管道在安裝過程中的振動和噪音的預(yù)防主要從以下幾個方面入手，如下：
Preventing vibration and noise is a key point in the process of installing ventilation pipes. The prevention of vibration and noise during the installation of Jinan ventilation pipeline mainly starts from the following aspects:
安裝風(fēng)機(jī)時，應(yīng)按設(shè)計要求或施工規(guī)范設(shè)置減振裝置。風(fēng)機(jī)與通風(fēng)管之間用軟管連接，風(fēng)機(jī)吸入口處的軟管安裝時應(yīng)松緊適度，避免因軟化、松動而減少進(jìn)、出風(fēng)口面積，產(chǎn)生噪音和振動。
When installing the fan, the vibration damping device shall be set according to the design requirements or construction specifications. The fan and the ventilation pipe are connected by hose. The hose at the fan inlet should be installed with appropriate tightness to avoid reducing the area of the air inlet and outlet due to softening and loosening, resulting in noise and vibration.
通風(fēng)管道的制造、安裝及與部件的連接應(yīng)緊密，不得有漏風(fēng)現(xiàn)象，以避免漏風(fēng)噪音。為防止通風(fēng)管道振動，在各系統(tǒng)通風(fēng)管道的彎曲處以及與通風(fēng)機(jī)和風(fēng)口的連接處設(shè)置固定支架。
The manufacturing, installation and connection with components of the ventilation duct shall be tight without air leakage to avoid air leakage noise. In order to prevent the vibration of the ventilation duct, fixed supports shall be set at the bend of the ventilation duct of each system and at the connection with the ventilator and the air outlet.
通風(fēng)管道安裝后，需進(jìn)行漏風(fēng)試驗。根據(jù)規(guī)定，通風(fēng)管道的漏風(fēng)測試采用漏光法和漏風(fēng)定量測試相結(jié)合的方法。漏光法適用于中低壓系統(tǒng)的嚴(yán)密性試驗。氣密性試驗適用于中壓系統(tǒng)的抽樣檢查和高壓系統(tǒng)的全檢。
After the installation of the ventilation duct, the air leakage test is required. According to the regulations, the air leakage test of the ventilation duct adopts the method of combining the light leakage method with the quantitative air leakage test. The light leakage method is applicable to the tightness test of medium and low pressure systems. The air tightness test is applicable to the sampling inspection of the medium pressure system and the full inspection of the high pressure system.
漏光檢測是利用光線對小孔的強(qiáng)烈穿透視覺，定性檢測系統(tǒng)中通風(fēng)管道密封性的方法。測試方法是在黑暗的環(huán)境下，在一定長度的通風(fēng)管道內(nèi)，使用電壓不高于36V、功率大于100W的帶保護(hù)罩的燈泡，從通風(fēng)管道的一端向另一端緩慢移動。如果在測試過程中可以在不銹鋼導(dǎo)管外觀察到光線，說明不銹鋼導(dǎo)管存在漏氣現(xiàn)象，應(yīng)修復(fù)通風(fēng)管的漏氣現(xiàn)象。
Light leakage detection is a method to qualitatively detect the tightness of the ventilation duct in the system by using the strong penetrating vision of light to the small hole. The test method is to use a light bulb with protective cover with voltage not higher than 36V and power greater than 100W in a certain length of ventilation duct in a dark environment, and move slowly from one end of the ventilation duct to the other end. If light can be observed outside the stainless steel conduit during the test, it indicates that there is air leakage in the stainless steel conduit, and the air leakage in the ventilation duct should be repaired.
此外通風(fēng)管道的材料應(yīng)根據(jù)應(yīng)用條件綜合選擇，一些通風(fēng)管道在技術(shù)上需要經(jīng)常移動，這需要柔性材料，如金屬軟管、塑料軟管和橡膠軟管。硬質(zhì)聚氯乙烯塑料板表面光滑，加工方便，但不耐高溫，適用于腐蝕性工業(yè)通風(fēng)和排氣系統(tǒng)。更多相關(guān)內(nèi)容就來我們網(wǎng)站

In addition, the materials of ventilation pipes should be comprehensively selected according to the application conditions. Some ventilation pipes need to move frequently in technology, which requires flexible materials, such as metal hose, plastic hose and rubber hose. Rigid polyvinyl chloride plastic plate has smooth surface and convenient processing, but it is not resistant to high temperature. It is suitable for corrosive industrial ventilation and exhaust system. Come to our website for more relevant content http://www.fsjt-gov.com Ask!
