空气在人们的生活中的必需品,没有空气人们会感到窒息,空气中的氧气也是维持人们生活的基本元素,所以我们要时刻保持室内通风,满足人们对氧气的需求,这也是通风管道加工对人们生活的影响,但济南通风管道加工过程中涉及到哪些质量问题呢?
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?
通风管道翘角及弯头视点禁绝
Ventilation pipe angle and elbow
①表现:矩形通风管道两相对平面、两端面不平行;折角不平直;对角线不相等;咬口不严。
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影响:会使通风管道连接受力不均匀,装置后的通风管道不平直,法兰盘垫片不严密,体系漏风,形成空调负荷损失,并且缩短使用寿命。
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:板下料放样禁绝确;通风管道两两平行,相对面的板料长度和宽度不相等。
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办法:打开下料时,应对板料严格角方,对每片板料的长度、宽度以及查验对角线,使它们的偏差控制在答应范围内;下料后的板料,应将通风管道相对面的两片板料重合查验尺寸准确性。
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.
由于厨房所在建筑物的格局以及厨房在建筑物中位置不同,有条件的厨房应由建筑物的集中空调系统进行有序送风。但目前所遇到的大部分情况是建筑物没有设置厨房的送风系统。许多带餐厅、厨房等的建筑物,仅设计了集中采暖系统而无集中空调系统。当厨房处于工作状态时,排风系统投入运行,厨房内处于负压状态,新风来源包括室外新风渗透和餐厅的空气大量补入厨房。
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.
