The thick steel plate round air duct is connected with the stainless steel air duct. First, the two sides of each pipe are rolled out with ribs, and one end of each pipe is reduced to a hole. When installing the equipment, insert the opening into the small opening according to the cyclone direction, use the steel hoop to tightly connect the drum hoops on both sides, and finally use the anchor bolt to wear it in the middle of the earrings to fix and tighten.

您引薦通風(fēng)管道抗震支架在生產(chǎn)制造時(shí),應(yīng)注意什么這些乞求:

What should you pay attention to when you introduce the anti-seismic support of ventilation duct

1、通風(fēng)管道抗震支架的形式、材料、生產(chǎn)加工規(guī)格、安裝間隔、生產(chǎn)制造精密度、電焊焊接等應(yīng)切合設(shè)計(jì)方案乞求,不可隨便變更,打孔必不可少選用臺(tái)鉆或手鉆,不可用氧乙炔焰開(kāi)孔.

1. The form, material, production and processing specification, installation interval, manufacturing precision and electric welding of the anti-seismic support for ventilation pipe shall meet the requirements of the design scheme, and shall not be changed at will. It is necessary to use bench drill or hand drill for drilling, and oxyacetylene flame shall not be used for drilling

2、抗震支架的絲桿園鋼應(yīng)依據(jù)風(fēng)管安裝設(shè)計(jì)標(biāo)高適當(dāng)提取.套絲不適合太長(zhǎng),絲口尾端不適合超過(guò)固定支架值,山東省通風(fēng)管道不可阻礙吊頂裝飾的工程施工.

2. The screw rod steel of the anti-seismic support should be extracted according to the design elevation of the air duct installation. The sleeve wire is not suitable to be too long, the end of the wire mouth is not suitable to exceed the fixed support value, and the ventilation pipe in Shandong Province should not hinder the construction of the ceiling decoration project

3、抗震支架的絲桿應(yīng)豎直,外螺紋應(yīng)完好無(wú)損、明亮.

3. The screw rod of seismic support shall be vertical, and the external thread shall be intact and bright

4、通風(fēng)管道抗震支架生產(chǎn)制造進(jìn)行后,應(yīng)中斷防銹處理后刷防腐漆二遍,再耍深灰色油漆二遍.埋進(jìn)墻、混泥土的位置不可漆料.

4. After the anti-seismic support of ventilation pipe is manufactured, the anti-corrosion treatment shall be interrupted, and then the anti-corrosion paint shall be painted twice, and then the dark gray paint shall be painted twice. The position buried in the wall and concrete shall not be painted

5、矩形框金屬材料水準(zhǔn)通風(fēng)風(fēng)管在較大容許安裝間距下,支架的少規(guī)格型號(hào)應(yīng)切合標(biāo)準(zhǔn),環(huán)形金屬材料水準(zhǔn)通風(fēng)風(fēng)管在山東省通風(fēng)管道大容許安裝間距下,支架的小規(guī)格型號(hào)應(yīng)切合標(biāo)準(zhǔn).關(guān)鍵用以通風(fēng)風(fēng)管與構(gòu)件(如熱管散熱器、靜壓箱側(cè)正壓送風(fēng)口等)的相接。設(shè)備時(shí)塑料軟管兩邊套在銜接的管內(nèi)，隨后用尤其軟的卡把塑料軟管箍緊。

5. When the rectangular frame metal material level ventilation duct has a large allowable installation distance, the small specification of the support should meet the standard. When the ring metal material level ventilation duct has a large allowable installation distance in Shandong Province, the small specification of the support should meet the standard. The key is to connect the ventilation duct with components (such as heat pipe radiator, positive pressure air supply outlet on the side of static pressure box, etc.). When using the equipment, both sides of the plastic hose are sheathed in the connecting pipe, and then the plastic hose is clamped tightly with a particularly soft clamp.
