通風(fēng)管道是用于工業(yè)和民用建筑的通風(fēng)和空調(diào)工程的金屬或非金屬管道。它們是一種市政基礎(chǔ)設(shè)施，可以使空氣流動(dòng)并減少有害氣體的濃度。大多數(shù)通風(fēng)管道都是由風(fēng)管加工設(shè)備制成。然而，由于各種原因，它可能導(dǎo)致制造的空氣管中的問(wèn)題。
Ventilation ducts are metal or non-metallic ducts used for ventilation and air conditioning engineering in industrial and civil buildings. They are a type of municipal infrastructure that allows air flow and reduces the concentration of harmful gases. Most ventilation ducts are made from duct processing equipment. However, due to various reasons, it may cause problems in the manufactured air ducts.
一、加工材料不符合標(biāo)準(zhǔn)。
1、 The processed materials do not meet the standards.
1.表現(xiàn)形式：板面不均勻，厚度不均勻，有明顯的壓痕，裂縫，沙眼，疤痕和銹跡風(fēng)管平面下沉，側(cè)向突出，變形明顯。
1. Manifestation: Uneven surface and thickness of the board, with obvious indentation, cracks, sand holes, scars, and rust marks. The air duct sinks flat, protrudes laterally, and deforms significantly.
2.效果：運(yùn)行期間，漏風(fēng)增加，空調(diào)負(fù)荷增加，風(fēng)力和性能受到影響。
2. Effect: During operation, air leakage increases, air conditioning load increases, and wind power and performance are affected.
3.原因：材料不合格，不能滿足制作風(fēng)管的需要。
3. Reason: The material is not qualified and cannot meet the needs of making air ducts.
4.措施：在使用風(fēng)道處理設(shè)備制作風(fēng)道之前，必須檢查材料的質(zhì)量證明和材料的外觀厚度，以確保材料可用。
4. Measures: Before using air duct processing equipment to make air ducts, it is necessary to check the quality certificate and appearance thickness of the materials to ensure their availability.
二、風(fēng)管的角度和彎頭的角度。
2、 The angle of the duct and the angle of the elbow.
1.性能：矩形導(dǎo)管兩個(gè)相對(duì)的平面，兩端不平行角度不直對(duì)角線不相等咬不嚴(yán)。
1. Performance: The rectangular conduit has two opposite planes, and the two ends are not parallel, the angle is not straight, the diagonal is not equal, and the bite is not tight.
2.效果：會(huì)使風(fēng)道連接不均勻，風(fēng)道安裝不直，法蘭墊圈不緊，系統(tǒng)漏風(fēng)，造成空調(diào)負(fù)荷損失，縮短使用壽命。
2. Effect: It will cause uneven connection of the air duct, uneven installation of the air duct, loose flange washers, and system air leakage, resulting in loss of air conditioning load and shortened service life.
3.原因：布局不準(zhǔn)確兩個(gè)平行的管道，與坯料的長(zhǎng)度和寬度相反是不一樣的。
3. Reason: Inaccurate layout. Two parallel pipes are different from the length and width of the blank.
4.尺寸：展開(kāi)沖裁時(shí)，紙張應(yīng)嚴(yán)格傾斜，并檢查每張紙的長(zhǎng)度，寬度和對(duì)角線，以便將其偏差控制在允許的范圍內(nèi)沖裁后，應(yīng)通過(guò)在風(fēng)道的另一側(cè)重疊兩個(gè)薄片來(lái)檢查金屬板的尺寸精度。
4. Size: When unfolding punching, the paper should be strictly tilted and the length, width, and diagonal of each sheet of paper should be checked to control its deviation within the allowable range. After punching, the dimensional accuracy of the metal plate should be checked by overlapping two thin sheets on the other side of the air duct.
