空氣在人們的生活中的必需品，沒有空氣人們會(huì)感到窒息，空氣中的氧氣也是維持人們生活的基本元素，所以我們要時(shí)刻保持室內(nèi)通風(fēng)，滿足人們對(duì)氧氣的需求，這也是通風(fēng)管道加工對(duì)人們生活的影響，但濟(jì)南通風(fēng)管道加工過程中涉及到哪些質(zhì)量問題呢?
Air is a necessity in people's life. People will feel suffocated without air. The oxygen in the air is also the basic element to maintain people's life. Therefore, we should always maintain indoor ventilation to meet people's demand for oxygen, which is also the impact of ventilation pipe processing on people's life. But what quality problems are involved in the process of Jinan ventilation pipe processing?
通風(fēng)管道翹角及彎頭視點(diǎn)禁絕
Ventilation pipe angle and elbow
①表現(xiàn)：矩形通風(fēng)管道兩相對(duì)平面、兩端面不平行;折角不平直;對(duì)角線不相等;咬口不嚴(yán)。
① Performance: two relative planes and two ends of rectangular ventilation duct are not parallel; the angle is not straight; the diagonal is not equal; the bite is not tight.
②影響：會(huì)使通風(fēng)管道連接受力不均勻，裝置后的通風(fēng)管道不平直，法蘭盤墊片不嚴(yán)密，體系漏風(fēng)，形成空調(diào)負(fù)荷損失，并且縮短使用壽命。
② Influence: it will make the ventilation pipe connection stress uneven, the ventilation pipe after the device is not straight, the flange gasket is not tight, the system air leakage, resulting in air conditioning load loss, and shorten the service life.

③原因：板下料放樣禁絕確;通風(fēng)管道兩兩平行，相對(duì)面的板料長度和寬度不相等。
③ Causes: the setting out of plate cutting is strictly forbidden; the ventilation pipes are parallel, and the length and width of plate on opposite side are not equal.
④辦法：打開下料時(shí)，應(yīng)對(duì)板料嚴(yán)格角方，對(duì)每片板料的長度、寬度以及查驗(yàn)對(duì)角線，使它們的偏差控制在答應(yīng)范圍內(nèi);下料后的板料，應(yīng)將通風(fēng)管道相對(duì)面的兩片板料重合查驗(yàn)尺寸準(zhǔn)確性。
④ Methods: when opening the blanking, the angle of the sheet should be strictly square, and the length, width and diagonal of each sheet should be checked, so that their deviation can be controlled within the allowable range; after blanking, the two sheets on the opposite side of the ventilation pipe should be overlapped to check the size accuracy.
由于廚房所在建筑物的格局以及廚房在建筑物中位置不同，有條件的廚房應(yīng)由建筑物的集中空調(diào)系統(tǒng)進(jìn)行有序送風(fēng)。但目前所遇到的大部分情況是建筑物沒有設(shè)置廚房的送風(fēng)系統(tǒng)。許多帶餐廳、廚房等的建筑物，僅設(shè)計(jì)了集中采暖系統(tǒng)而無集中空調(diào)系統(tǒng)。當(dāng)廚房處于工作狀態(tài)時(shí)，排風(fēng)系統(tǒng)投入運(yùn)行，廚房內(nèi)處于負(fù)壓狀態(tài)，新風(fēng)來源包括室外新風(fēng)滲透和餐廳的空氣大量補(bǔ)入廚房。
Due to the different layout of the building where the kitchen is located and the different position of the kitchen in the building, the conditional kitchen should be orderly supplied by the building's central air conditioning system. But at present, most of the situation is that the building does not have a kitchen air supply system. Many buildings with restaurants and kitchens are only designed with central heating system but without central air conditioning system. When the kitchen is in the working state, the exhaust system is put into operation, and the kitchen is in the negative pressure state. The fresh air sources include outdoor fresh air infiltration and a large amount of restaurant air into the kitchen.
