通风管道弯头是如何制作的?

发布人:   发布时间:2021-03-26 17:23:41

通风管弯头(材质SUS201、SUS304、SUS316、SUS321),因其具有优异的耐腐蚀、耐点蚀、耐腐蚀、耐热、强度高等理化性能。因此,对通风管道的弯头,制造商应使板的刚性角为正方形,查抄板的长度、宽度和对角线,并将偏差控制在准许范围内。

Ventilation pipe elbows (SUS201, SUS304, SUS316, SUS321) have excellent physical and chemical properties such as corrosion resistance, pitting corrosion resistance, corrosion resistance, heat resistance and high strength. Therefore, for the elbow of ventilation duct, the manufacturer should make the rigid angle of the plate square, check the length, width and diagonal of the plate, and control the deviation within the allowable range.

1.使用水帘,夏季炎热时,车间温度可控制在28摄氏度以下。对于那些比空调更长的水帘的人来说,人体的凉爽感觉是冷的和不成容忍的。在任何需要通风管道处理设备的环境中,持久风和雨城市造成材料老化、转化、腐蚀和生锈,镀锌钢管镀锌层,但保持铁管,因此不会氧化。

  1. Using water curtain, the temperature of workshop can be controlled below 28 ℃ in hot summer. For those with longer water curtain than air conditioner, the cool feeling of human body is cold and intolerable. In any environment requiring ventilation pipe treatment equipment, long-term wind and rain will cause material aging, transformation, corrosion and rust. Galvanized steel pipe is galvanized, but the iron pipe is kept, so it will not be oxidized.

2.通风管道弯头,是操作自然通风窗口的,自然风和温度差的影响下,窗的总面积是1/3的建筑面积。从展示可以看出,对于普通的低层住宅,该计划可以两壁排气口之间进行选择,并为高层公寓。要求会更高,厨房油烟规划的高度2米以上,和对出口厨房排气,规划成圆孔,直径为170-200mm之间它。温室通常强制通风系统或低压轴流风扇循环风扇。

2. The elbow of ventilation pipe is made of natural ventilation window. Under the influence of natural wind and temperature difference, the total area of the window is 1 / 3 of the building area. It can be seen from the exhibition that for ordinary low rise residential buildings, the plan can choose between the two wall exhaust outlets, and it is a high-rise apartment. The requirements will be higher. The height of kitchen lampblack planning is more than 2 meters, and the outlet kitchen exhaust is planned to be a round hole with a diameter of 170-200 mm. Greenhouse is usually forced ventilation system or low-pressure axial fan circulation fan.

3.按照设计制造尺度的要求,通风管道弯头、采矿用橡胶涂层风管、采矿用塑料通风管等均禁止使用防火有机材料,要求具有阻燃、防静电的矿山安全性能,风管施工及较复杂的民用建筑,在设计阶段,各种工作(暖通、给排水、供照明及建筑)应首先通过空间分隔来确定各种管道的高度范围。

3. According to the requirements of design and manufacturing standards, the use of fire-resistant organic materials is prohibited for ventilation duct elbows, rubber coated ventilation ducts for mining, plastic ventilation ducts for mining, etc., and the mine safety performance of flame retardant and anti-static is required. In the design stage, all kinds of work (HVAC, water supply and drainage, lighting and construction) should first pass the space division To determine the height range of various pipelines.

因此,在工程设计中,必需采用普通的通风管道作为火灾制糖区的排烟管道,以减少对上通风空间的占用和风管的消耗。

Therefore, in the engineering design, the common ventilation pipe must be used as the smoke exhaust pipe in the fire sugar making area, so as to reduce the occupation of the upper ventilation space and the consumption of the air pipe.
