1.管板材的開(kāi)槽

Slotting of 1. tubes

板材開(kāi)槽的種類(lèi)有三種：一塊板開(kāi)槽法、二塊板開(kāi)槽法、四塊板開(kāi)槽法。板材開(kāi)槽的方法有兩種：手工開(kāi)槽法、機(jī)械開(kāi)槽法。

There are three kinds of slotted plates: one plate slotting method, two plate slotting method and four plate slotting method. There are two kinds of slotting methods: manual slotting method and mechanical slotting method.

2.密封

2. seal

消音通風(fēng)管道系統(tǒng)建議使用的密封膠帶有：熱敏膠帶、壓敏膠帶兩種。在管道未用膠帶密封前，應(yīng)先使用專用的扒形裝訂針，對(duì)管道的搭接口進(jìn)行固定，裝訂針的間距為50mm一個(gè)。裝訂時(shí)，裝訂針應(yīng)與接縫略呈角度。裝訂針僅用于有蓋舌的搭接口固定，若無(wú)蓋舌，或平接口時(shí)，應(yīng)用膠帶接片進(jìn)行固定，膠帶較大為300mm，每邊少1個(gè)。

Energy saving silencer ventilation duct system recommended sealing tape: heat sensitive tape, pressure-sensitive adhesive tape two. Before the pipe is sealed with adhesive tape, the special binding pin shall be used to fix the interface of the pipe, and the spacing of the binding needle is 50mm. When binding, the binding pin should be slightly angled to the seam. The staple is used only by the tongue cover interface is fixed, if there is no cap tongue or flat interface, application of fixed tape splicing tape, maximum 300mm, each side of at least 1.

3.加固

3. reinforcement

當(dāng)通風(fēng)管道系統(tǒng)內(nèi)部的靜壓負(fù)載使玻纖通風(fēng)管道管道壁出現(xiàn)1%的撓度時(shí)，就需要對(duì)通風(fēng)管道管道進(jìn)行加固。通常消音通風(fēng)管道系統(tǒng)管道可采用以下方法來(lái)進(jìn)行加固：a.拉桿加固法，它是采用鋼彩、套管加固，通常使用在500Pa以下的正壓加固。b.框架加固法，即采用輕鋼龍骨加固。c.抱合加固法，即采用輕鋼龍骨加固，使用在拉桿加固和框架加固無(wú)法應(yīng)用的某些特殊管道上，如900彎管、三通管、悶頭管等。d.防下垂加固法，它用于特殊管道的加固，如變經(jīng)管道加固和迂回管道加固。

When the static pressure of the ventilation duct system makes the 1% deflection of the glass fiber ventilation pipeline wall, it is necessary to reinforce the ventilation pipe and pipeline. Normally, energy-saving, silencing, ventilation, ductwork, piping can be strengthened by the following methods: A. tie bar reinforcement method, which is strengthened by steel color and casing, usually used under 500Pa reinforcement. B. frame reinforcement method, that is, the use of light steel keel reinforcement. C. cohesion reinforcement method, which uses light steel keel reinforcement reinforcement, using some special pipeline cannot be applied in strengthening and frame, such as 900, three elbow pipe and tube bulkhead. D. anti sagging reinforcing method used for reinforcement of special pipes, such as warp reinforcement and bypass reinforcement.

4.破損修補(bǔ)

4. damaged repair

如果是管道外表面很輕微的破損，可以用專用的密封膠帶來(lái)進(jìn)行修補(bǔ)即可。如果是管道內(nèi)表面有輕微破損，則可用舒伯專用修補(bǔ)膠進(jìn)行修補(bǔ)。如果管道外表面的鋁箔層發(fā)生破損，而玻纖保溫層未發(fā)生損壞，則可選用一片合格的鋁箔片進(jìn)行管道鋁箔表面的修補(bǔ)。

If the outer surface of the pipe is slightly damaged, it can be repaired with a special sealed adhesive tape. If there is a slight damage to the inner surface of the pipe, it can be repaired with special repair adhesive. If the aluminum coating on the outer surface of the pipe is damaged and the glass fiber insulation layer is not damaged, a qualified aluminum foil can be used to repair the surface of the pipe foil.

如果管道壁的破損已達(dá)到玻纖保溫層時(shí)，則可將破損的地方切割下來(lái)，開(kāi)出雌雄搭接口，另選一塊完好的板材，根據(jù)切割下來(lái)的玻板尺寸切割好，留下雌雄搭接口，在四周接口上涂上修補(bǔ)膠及粘膠劑，根據(jù)工藝規(guī)范進(jìn)行密封。如果管道的破損比較嚴(yán)重，且破損面積比較大，有可能會(huì)影響通風(fēng)管道系統(tǒng)的正常運(yùn)行時(shí)，就需要對(duì)管道進(jìn)行更換修補(bǔ)，以保證系統(tǒng)的正常運(yùn)行。

If the damaged pipe wall of glass fiber insulation layer has been reached, it can be damaged areas cut out of a male and female interface, choose a block intact plate, according to the size of glass cut cut, leaving a female interface around the interface with the repair glue and adhesive seal, according to process specification. If the damage of the pipeline is serious and the damage area is relatively large, it may affect the normal operation of the ventilation pipe system, so it is necessary to replace and repair the pipe so as to ensure the normal operation of the system.
