通風(fēng)管道作業(yè)條件：一般送風(fēng)機(jī)系統(tǒng)和空調(diào)系統(tǒng)的安裝，要在建筑物圍護(hù)結(jié)構(gòu)施工完，障礙物已清理，地面無(wú)雜物的條件下進(jìn)行。風(fēng)管加工對(duì)空氣潔凈系統(tǒng)的安裝，應(yīng)在建筑物內(nèi)部安裝部件的地面已做好，墻面已抹灰完畢，室內(nèi)無(wú)灰塵飛揚(yáng)或有防塵措施的條件下進(jìn)行。

Working conditions of ventilation duct: generally, the installation of forced draft fan system and air conditioning system shall be carried out after the construction of building envelope, the obstacles have been cleared and the ground is free of sundries. The installation of air cleaning system for air duct processing shall be carried out under the condition that the ground of the components installed inside the building has been completed, the wall has been plastered, and there is no dust flying or dust-proof measures in the room.

一般除塵系統(tǒng)風(fēng)管安裝宜在廠房的工藝設(shè)備安裝完或設(shè)備基礎(chǔ)已確定，設(shè)備連接器、罩體方位已知的情況下進(jìn)行。檢查現(xiàn)場(chǎng)預(yù)留孔洞位置、尺寸應(yīng)符合圖紙要求，每邊比實(shí)際截面大100mm。

The air duct of general dust removal system should be installed after the process equipment of the plant is installed or the equipment foundation has been determined, and the orientation of equipment connector and cover body is known. Check that the position and size of the reserved holes on site shall meet the requirements of the drawing, and each side shall be 100mm larger than the actual section.

通風(fēng)管道材質(zhì)要求：各種安裝材料應(yīng)具有出廠合格證明書(shū)或質(zhì)量鑒定文件及產(chǎn)品清單。風(fēng)管成品不允許有變形、扭曲、開(kāi)裂、孔洞、法蘭脫落、開(kāi)焊、漏鉚、漏打螺栓孔等缺陷;安裝的閥體、風(fēng)口等部件應(yīng)檢查調(diào)節(jié)裝置是否靈活，消聲片、油漆層有無(wú)損傷。安裝使用的材料：螺栓、螺母、墊圈、墊料、密封條、自攻螺釘，拉鉚釘，焊條、各種帆布、無(wú)紡布、射釘、膨脹螺栓應(yīng)符合產(chǎn)品質(zhì)量要求。鐵皮管道廠家在制作時(shí),其所用板材、螺旋風(fēng)管廠家型材以及其他主要成品材料制作要求十分嚴(yán)格。焊縫應(yīng)作外觀檢查,不應(yīng)有氣孔、砂眼、夾渣、裂紋等缺陷,焊接后鋼板的變形應(yīng)矯正。

Material requirements for ventilation duct: various installation materials shall have factory certificate or quality appraisal document and product list. The finished air duct shall be free of deformation, distortion, cracking, holes, flange falling off, open welding, missing riveting, missing bolt holes and other defects; For the installed valve body, air outlet and other components, check whether the regulating device is flexible and whether the silencing sheet and paint layer are damaged. Materials used for installation: bolts, nuts, washers, gaskets, sealing strips, self tapping screws, pull rivets, welding rods, various canvas, non-woven fabrics, shooting nails and expansion bolts shall meet the product quality requirements. During the production of sheet iron pipe manufacturers, the production requirements of plates, profiles of spiral air duct manufacturers and other main finished materials are very strict. The weld shall be visually inspected without defects such as pores, sand holes, slag inclusions and cracks. The deformation of the steel plate after welding shall be corrected.

鐵皮風(fēng)管的風(fēng)道與風(fēng)口接合用帶保溫層的軟管連接。鐵皮風(fēng)管的風(fēng)道安裝應(yīng)平、直, 共板風(fēng)管主風(fēng)道安裝不直度≤1.5㎜/m,不平度≤1㎜/m。鐵皮風(fēng)管和配件表面平整、圓弧均勻、縱向接縫應(yīng)錯(cuò)開(kāi),咬口縫應(yīng)緊密,寬度均勻。鐵皮管道廠家介紹鐵皮風(fēng)管除具有剛度好、強(qiáng)度大的優(yōu)點(diǎn)外，又具有吸音降噪、保溫隔熱不需要二次保溫的性能，克服了以前復(fù)合風(fēng)管強(qiáng)度弱，外壁易破損的弱點(diǎn)，發(fā)揚(yáng)了鍍鋅鐵皮的優(yōu)勢(shì)，風(fēng)管廠家使用壽命更長(zhǎng)，且美觀大方，更顯尊貴本色。內(nèi)層保溫材料為有機(jī)材料中不燃性能＊好的酚醛泡沫，管道在成型后不需要二次保溫，并且具有和消聲功能。

The air duct of the iron sheet air duct is connected with the air outlet with a hose with an insulating layer. The air duct of iron sheet air duct shall be installed flat and straight. The non straightness of the main air duct of common plate air duct shall be ≤ 1.5mm/m and the non flatness shall be ≤ 1mm / m. The surface of iron sheet air duct and accessories shall be flat, the arc shall be uniform, the longitudinal joints shall be staggered, the undercut joints shall be tight and the width shall be uniform. In addition to the advantages of good stiffness and high strength, iron duct has the performance of sound absorption, noise reduction, thermal insulation and no need for secondary insulation. It overcomes the weakness of weak strength of composite duct and easy damage of outer wall in the past, and carries forward the advantages of galvanized iron sheet. The service life of air duct manufacturers is longer, beautiful and generous, showing more noble nature. The inner insulation materials are nonflammable properties of organic materials * good phenolic foam. The pipes do not need two heat preservation after molding, and have antibacterial and silencing functions.
