風(fēng)管主要是指空調(diào)系統(tǒng)的
通風(fēng)管道,它常常被忽視但它卻是空調(diào)系統(tǒng)的重要組成部分，那么，我們?cè)诎惭b風(fēng)管時(shí)會(huì)遇到哪些常見(jiàn)問(wèn)題呢?如何解決呢?下面一起來(lái)看看吧。
The air duct mainly refers to the ventilation duct of the central air conditioning system, which is often ignored but it is an important part of the air conditioning system. Then, what common problems will we encounter when installing the air duct? How to solve them? Let's take a look.
風(fēng)管安裝有哪些常見(jiàn)問(wèn)題?
What are the common problems with duct installation?
1、材料不符合質(zhì)量要求
1. Material does not meet quality requirements
這種問(wèn)題是比較讓人頭疼的問(wèn)題，如果材料不符合要求，系統(tǒng)運(yùn)行時(shí)，風(fēng)管會(huì)漏風(fēng)，造成不應(yīng)有的空調(diào)負(fù)荷損失，并且影響風(fēng)管的使用壽命。
This kind of problem is quite a headache. If the material does not meet the requirements, the air duct will leak when the system is running, resulting in the loss of air conditioning load and affecting the service life of the air duct.
2、風(fēng)管出現(xiàn)噪聲
2. Duct noise
引起這種現(xiàn)象的原因可能是板材表面不平整，厚度不均勻，有明顯的壓痕、裂紋、砂眼、結(jié)疤和銹蝕等，或者是風(fēng)管平面下沉，側(cè)面向外凸起，有明顯的變形。
The cause of this phenomenon may be the uneven surface and thickness of the plate, obvious indentation, crack, sand hole, scar and rust, etc., or the air duct plane sinks, the side bulges outwards, and obvious deformation.
3、風(fēng)管翹角、扭曲及彎頭角度不準(zhǔn)
3. The angle of air duct warping, twisting and the angle of elbow are not correct
這是由于板下料放樣不準(zhǔn)確;風(fēng)管兩兩平行，相對(duì)面的板料長(zhǎng)度和寬度不相等;風(fēng)管的四角處咬口寬度不相等;咬口縫設(shè)置部位不對(duì)，手工咬口縫用力大小不一樣;未采取相應(yīng)的加固措施。這樣的情況會(huì)導(dǎo)致矩形風(fēng)管相對(duì)平面不平行、兩端面不平行;折角不平直;對(duì)角線不相等;咬口不嚴(yán)。的直接結(jié)果就是會(huì)使風(fēng)管連接受力不均勻，安裝后的風(fēng)管不平直，法蘭盤(pán)墊片不嚴(yán)密，系統(tǒng)漏風(fēng)，造成空調(diào)負(fù)荷損失，并且縮短使用壽命。
This is due to the inaccurate setting out of slab cutting; the two air ducts are parallel, and the length and width of the slab on the opposite side are not equal; the width of the undercut at the four corners of the air duct is not equal; the location of the undercut joint is not correct, and the strength of the manual undercut joint is not the same; no corresponding reinforcement measures have been taken. In this case, the relative plane of the rectangular air duct is not parallel, and the two ends are not parallel; the angle is not straight; the diagonal is not equal; and the undercut is not strict. The final direct result is that the air duct connection will be uneven in stress, the installed air duct is not straight, the flange gasket is not tight, the system leaks air, resulting in air conditioning load loss, and shortening the service life.
風(fēng)管安裝的解決辦法：
Solutions for duct installation:
1、安裝前對(duì)材料進(jìn)行質(zhì)量檢查
1. Quality inspection of materials before installation
仔細(xì)測(cè)量鋼板厚度，在風(fēng)管安裝前一定要注意先檢查材料出廠合格證書(shū)和材料質(zhì)量證明，然后檢查材料外觀;再測(cè)量鋼板厚度。防止因材料不符合要求而返工。
Carefully measure the thickness of the steel plate. Before installing the air duct, be sure to check the factory certificate and material quality certificate of the materials, then check the appearance of the materials, and then measure the thickness of the steel plate. Prevent rework due to non-conforming materials.
2、吊裝安全要保證
2. Safety of hoisting
潔凈風(fēng)管的吊裝與普通風(fēng)管一樣，要求吊桿、橫擔(dān)、膨脹螺栓、保溫風(fēng)管下部墊木等符合有關(guān)規(guī)范和質(zhì)量驗(yàn)收標(biāo)準(zhǔn)。
The hoisting of clean air duct is the same as that of ordinary air duct, and the suspender, cross arm, expansion bolt, underlay of thermal insulation air duct, etc. are required to meet the relevant specifications and quality acceptance standards.
3、注意展開(kāi)下料步驟
3. Pay attention to unfolding the blanking steps
要讓施工人員對(duì)板料嚴(yán)格檢查，對(duì)每片板料的長(zhǎng)度、寬度以及對(duì)角線，使它們的偏差控制在允許范圍內(nèi);下料后的板料，應(yīng)該將風(fēng)管相對(duì)面的兩片板料重合起來(lái)，檢驗(yàn)尺寸的準(zhǔn)確性;板料咬口預(yù)留尺寸必須正確，以保證咬口寬度一致;咬口縫設(shè)在四角部位，手工咬口合縫時(shí)，用木錘先將咬口兩端部位打緊，再沿全長(zhǎng)均勻打?qū)崱?/div>
The construction personnel shall strictly check the sheet metal, and control the length, width and diagonal of each sheet metal to make their deviation within the allowable range; for the sheet metal after blanking, the two sheets on the opposite side of the air duct shall be overlapped to check the accuracy of the size; the pre reserved size of the sheet metal undercut must be correct to ensure the same undercut width; The seaming joint is set at the four corners. When the seaming joint is made by hand, the center part at both ends of the seaming joint shall be tightened with a wooden hammer first, and then the joint shall be evenly compacted along the whole length.
4、做好漏光檢查
4. Check the light leakage
風(fēng)管地面組裝后，在未做保溫前應(yīng)進(jìn)行漏光檢查，根據(jù)現(xiàn)場(chǎng)情況可按內(nèi)漏光或外漏光檢查，在漏光處需補(bǔ)密封膠，直至無(wú)漏光時(shí)方可進(jìn)行保溫。
After the air duct is assembled on the ground, the light leakage inspection shall be carried out before the heat preservation. According to the site conditions, the light leakage inspection can be carried out according to the internal light leakage or external light leakage. Sealant shall be added at the light leakage place until there is no light leakage.
5、漏風(fēng)量測(cè)試
5. Air leakage test
對(duì)于等級(jí)較高的凈化系統(tǒng)的送回風(fēng)總管和支干管，在地面組對(duì)后除做漏光檢查外，還應(yīng)做漏風(fēng)量測(cè)試。對(duì)于較小的系統(tǒng)可在風(fēng)管安裝后測(cè)試，對(duì)于較大的系統(tǒng)盡可能在地面分段組裝后進(jìn)行，這樣便于發(fā)現(xiàn)問(wèn)題及時(shí)處理。
For the air supply and return main pipe and branch main pipe of the purification system with higher level, besides light leakage inspection, air leakage test shall also be conducted after the ground assembly. For the smaller system, it can be tested after the installation of air duct, and for the larger system, it can be assembled in sections on the ground as much as possible, so that problems can be found and dealt with in time.
6、墊料要選好
6. Select the padding
風(fēng)管法蘭連接處的墊料，應(yīng)選擇不透氣、不產(chǎn)塵、彈性好不易老化的材料，如閉孔海綿橡膠板、軟橡膠板等組成，墊料的厚度5～8mm，接頭處應(yīng)加工成階梯形，嚴(yán)禁直接對(duì)接。
The gasket at the joint of air duct flange shall be made of airtight, dust-free, elastic and aging resistant materials, such as closed cell sponge rubber plate, soft rubber plate, etc. the thickness of the gasket shall be 5-8mm, and the joint shall be processed into ladder shape, and direct butt joint is strictly prohibited.
關(guān)于風(fēng)管安裝的相關(guān)知識(shí)小編就給大家介紹到這里，風(fēng)管安裝是否規(guī)范非常重要，大家在施工過(guò)程中要仔細(xì)。
The relevant knowledge of air duct installation will be introduced here. Whether the air duct installation is standard or not is very important. You should be careful in the construction process.
